iPhone 4 now plays 1080p videos easily, then why Galaxy S can't - Galaxy S I9000 Q&A, Help & Troubleshooting

http://blog.gsmarena.com/iphone-4-now-plays-1080p-videos-easily-does-some-xviddivx-magic-too/
Seems like some people managed to play 1080p on iPhone 4.
SGS has almost the same CPU with better GPU and option for overclock.
What is the reason that is preventing us from playing 1080p? Not good enough app or something else?

1080p on a 4" screen? no thank you.

We just seems to be needing a good codec to play 1080p. So it should just be a software limitation unless the GPU is capped at 720p!

I would never watch 1080p on 4'' screen (even though some people would)
I'm just curios about the hardware.
@Prankey,
I guess SGX 540 can play 1080p if SGX 535 can.

I'll make a wild guess here:
iOS has all the software needed for full hardware acceleration while Android don't.

How is this a development related question?
And I thought galaxy can play 1080 without problems (didnt try though, as its very stupid).

so iPhone display is 960 x 640 pixels?
1080P is 1920 x 1080 pixels
unless it can output HDMI, seems pretty pointless to me.

The screen resolution is 800x480 anyway so the extra resolution does not benefit you at all. It's just a minor convenience to avoid converting the video but you're wasting battery power to decode the video and a lot of space. 720p is enough of a battery and space waster.

1080p isn't even listed as a file which can be played. You can't even upload it via iTunes, so there is no official hardware acceleration built in for 1080p.

I guess it is a development question, because it may be related with codecs, drivers, etc.
But no, it can't. I have tried it, even though I'm not about to watch full HD on my SGS

We can use microUSB to HDMI and we have DLNA. So it would be useful to us. Anyway, as I've already said my interest is about hardware capabilities not watching full HD on my phone.

You still have to convert the video though for these devices still cause h.264 codec support for mobile devices don't support all of what the codec can do. It's also wasted bit rate as well. It's better to have a lower resolution video with a decent bit rate then it is to have a video with a massive resolution but not enough of a bit rate to smooth out artifacts. this resolution race for videos on mobile phones is a tad stupid.

Rock player plays 1080p for me.
The Video I tried was a bit choppy though but acceptable.
(I guess about 15-18fps). I only tried one Video wich I accidentally loaded on my device.
As far as I now Rock player does not use any GPU acceleration though pretty impressive what this little CPU is capable of.
Definatly plays full hd better then my atom netbook.

all the extra processing is wasted on a 4" screen
actually iphone4 is only 3.5" not even 4"
720p is more than enough on the 4"

I wasn't talking about hardware accelerated 1080p playback. I was talking about how everything in iOS is adapted to support as much of the hardware features as possible, while Android is not adapted to support the SGS hardware in any other way than Samsung just tossing in (semi)working drivers.

1/ there is no point, resolution-wise
2/ with iphone there is a VERY limited range of file formats you CAN actually play, so you will spend half your life converting to a format that apple can control. Most my 1080p movies are mkv format, a format that works on Galaxy S but not on iphone. All my SD movies are Divx and Xvid, again, not compatible with iphone.
Mark.

Well actually we can! Rockplayer can do it so please stop spamming this forum!
You apple fanboy

And why not? 802.11n is more than enough for that...

Anything that can be done on the iphone 4 can be done on the galaxy s, just needs the right software to be made.
The only difference between the iphone 4 and the GS is the software, the screen, and the galaxy s having one generation newer gpu
Anyway what's the point in this? sd cards have a 4gb filesize limit, 1080p would waste so much battery for no benefit over a 720p file

technical spec yes
real life usage, not so great
wireless N is what i use for my home teather, yes it "works" but load time is horrible, as well as the random cut offs, then waiting for the load time again.... it's a pain in the aussie
it's much more convenient to first copy the entire movie into the hard drive via wireless N, then watch it
but that defeats the entire purpose of streaming a movie

The Acer Liquid can play 720P videos but not the HD2, WTH?

Just saw this :
http://www.mobiletechworld.com/2009/12/21/acer-liquid-reviewed/
WTH? It's either HTC's fault or Microsofts'/WinMo.Kinda sad that a 1Ghz SnapDragon can't do it compared to the underclocked Acer Liquid.
So what? 720p playback is ONLY useful if you don't have to convert the files or if you want to play them on a TV.
No phone is able to play 720p video without conversion. So the only advantage would be to be able to play HD video via TV out. But the HD2 does not have TV out, so 720p playback would be absolutely useless on the HD2.
On the Acer , like on any other phone, you STILL have to convert the files. It will only play .mp4 video in 720p.
If you play them on the phone, then it doesn't matter whether you convert them to 720p or 480p, the screen is only 800x480 pixels. You have to convert them anyways.
And yes, it's HTC's fault, because they don't fully use the Snapdragon chipset. It has nothing to do with Windows Mobile. But it doesn't matter anyways unless the phone has TV out.
Maybe in a not so far, far away future, it will make sense to have 1080p (or even higher, who knows) capable mobile devices - as soon as they are intended to deliver that high resolution content to a really, really large display.
Watching 480 lines of resolution on a 4.3" screen comes close to watching a 1080p BluRay movie on a 50" TV set, no?
As of today, I am just happy with what HD2 delivers... and for the home cinema experience, I do prefer the "big" screen anyway.

But as the HD2 does not have TV out, 720p playback would be useless.
(because you'd not be ably to use files from your PC without conversion anyways)
Who says you cant play them with out conversion? I have never converted one file to play on my phone. So yes it would be useful. It its capable of doing it, why the hell cant it, there is not argument here.
It can do it, so it should be able to, simple as that.

720p works only with hardware acceleration. Hardware acceleration works only for videos converted to the right file format.
No phone currently supports 720p playback without conversion because conversion is needed in order to use the hardware acceleration that the (Snapdragon) chipset provides.
It doesn't matter whether you own an Acer Liquid, an HTC Bravo or an HTC HD2, none of them will play your 720p .avi files from your PC. You have to convert them first.
Conclusion: 720p playback without TV out is useless. Period.
I'm pretty sure HTC left out the HD playback support because they wanted to save money on developing/purchasing the necessary software/drivers. And that is a wise decision for a device without TV out, because 720p playback is useless when you still have to convert the files and have no TV out.
Heu HD2 is able to play 720p
The only bad thing is the non support of AC3 in coreplayer

That is only the case because of the stupidity and narrow-mindedness of HTC and Qualcomm (and, to a degree, Microsoft). There is no technical reason why an application shouldn't be able to handle a much wider range of codecs and still take full advantage of hardware acceleration. But Qualcomm insists on charging too much for the intellectual property rights to run software that is optimised for its hardware; HTC is too mean-minded to pay Qualcomm's fees and too lazy to ship its own multi-format software player (compare with, say, Samsung, whose proprietary video player software is both hardware-accelerated and extremely flexible about formats); and Microsoft can't be arsed to make Pocket Media Player support a sufficient range of formats and codecs either.
One can even quite reasonably blame the authors of Coreplayer for not having yet launched a version capable of using NEON instructions for video acceleration (something that is in the public domain and not under Qualcomm's control). All in all it's a bloody waste.

I completely disagree. Plenty of video is only available in 720p format; even for stuff that is available in 720p and low-res versions, the low-res version is often so low-res that downscaling the HD version would look a lot better on a screen the size of the HD2. It would be enormously much more convenient if one could simply download and play the 720p version without having to spend hour after hour after hour on conversion, and use only one version of the fule on both the phone and a desktop PC. Obviously this is not something you personally would find useful, but that doesn't mean you have to be such a dog-in-the-manger about it: the attitude of "I don't want to do it, therefore no one needs to or should be allowed to" is really rather narrow-minded.
Shasarak,
you don't understand. You are making assumptions that are simply not true. Let me correct you:
That is only the case because of the stupidity and narrow-mindedness of HTC and Qualcomm (and, to a degree, Microsoft).

Wrong: It has NOTHING to do with Microsoft and HTC. Nothing. It is only because of the Qualcomm chipset, that only supports acceleration for certain video formats.
BUT this is not an 'issue' limited to Qualcomm! There is no phone chipset that supports hardware acceleration of different video formats!
There is no technical reason why an application shouldn't be able to handle a much wider range of codecs and still take full advantage of hardware acceleration.

I don't know about the reasons, but fact is that NO phone chipsets supports that acceleration. So there must be a reason.
Even IF Microsoft or HTC would develop/pay for the appropriate software, the phones would STILL not be able to play other file formats because the chipset simply doesn't support it.
And other chipsets (not from Qualcomm) don't support it either.
It would be enormously much more convenient if one could simply download and play the 720p version without having to spend hour after hour after hour on conversion,
Click to expand...

Sure, it would be more convenient.
BUT as I explained several times: It doesn't matter whether the phone supports 720p playback or not, because conversion is always necessary due to limitations of the chipset, which only supports acceleration for certail formats (which applies not only to Qualcomm chipsets, but to every other chipset as well).
Obviously this is not something you personally would find useful, but that doesn't mean you have to be such a dog-in-the-manger about it: the attitude of "I don't want to do it, therefore no one needs to or should be allowed to" is really rather narrow-minded.

Thsi is not my attitude.
PLEASE READ PROPERLY BEFORE YOU ATTACK PEOPLE.
I explained to you in detail why 720p playback ability does NOT mean that conversion is not necessary. Thus, your argument of "not having to convert the videos" is misplaced. As you can read in the article above, the Acer Liquid ONLY plays 720p video that has been converted. And this is the case with any other phone as well, because of the reasons I explained above.
I dont know much about playback in 720p on the HD2 yet, but
Damien123_666 has done loads of camera tweaks (very good by the looks of it) and if you notice, he is working on recording in 720p
im working on 720p, micro-modes, bmp files and also increased video quality so keep looking for updates daily
Click to expand...
Click to collapse
So theres obviously the potential
Damiens thread is about recording 720p video, not playing it. Afaik Snapdragon has the potential of recording 720p video.
Here it's true, HTC is to blame for not enabling it.
But what I was talking about is 720p playback.
This is only possible with hardware acceleration.
Hardware acceleration is only possible for certain formats.
This means: Even if your phone supports 720p playback, you still have to convert the files.
Shasarak said that 720p would be a benefit because we would not have to convert the files.
But that's not true.
Even if HTC would develop/purchase the necessary software, we would STILL have to convert the videos.
(like on the Liquid, see the linked post)
That means: The argument of "not having to convert the videos" is not applicable here, because it doesn't matter whether the phone supports 720p or not, the files must ALWAYS be converted.
This means: The only advantage of 720p would be playing back HD videos on a TV.
But our HD2 does not have TV out.
This means: 720p playback capability would not be useful for us, as we would still have to convert the files and we don't have TV out.
I hope that was clear enough now.
@Shasarak
You CAN blame HTC/Microsoft for not enabling 720p playback, that's true.
BUT even IF they would enable it, they could ONLY enable it for certain file formats. You CAN NOT blame them for not enabling 720p for all formats, because this is a hardware limitation that exists on all other phones as well, no matter what manufacturer or OS.
I think you will find that people were blaming HTC for not enabling support. No one was complaining about it being available on only certain formats.
If my phone is capable of something, then I would like it to be able to do it. Simple as that.
No, you got it wrong, too.
People are not only blaming HTC for not enabling 720p playback, they are also blaming HTC/MS for not enabling it for all formats, and that's nonsense because that is not HTC's or MS's fault but a hardware limitation.
Just because the hardware is capable doesn't mean you can expect the support. It also needs software and that adds additional developing costs!
If HTC would have enabled it, they would have had additional costs, which means the phone would have been more expensive for you.
You can only expect what you pay for. You paid NOT for 720p video support, because that was not advertised anywhere by HTC.
HTC made the desicion not to enable it in order to be able to sell the phone at lower price. You either respect that desicion or buy another phone. You can not expect anything that nobody promised to you.
And as explained before, due to the fact that conversion is ALWAYS needed, 720p support is useless without TV out. You should be happy that you didn't have to pay for a useless feature.
seed_al
WTF are you talking about? Convertion is always needed? The CPU will downscale the video on the fly to fit the screen. You don't seem to know much (just like the Zunehd does). Any CPU is capable of.playing any format as long as the software enables it. You don't seem to understand this. SnapDragon just like nVidia's Tegra APX (& iPhone 3GS) is capable of decoding 720p WMV/MP4/H.264 at a bitrate up to 14bit/s 29fps. Even a feking Pentium2 can do this but at something like 0.02fps. The fact is that the software/drivers on WinMo aren't provided on the HD2
@MasterTP
Wrong. Completely.
You're mixing up hardware and software decoding! Do some research.
Of course any CPU can play anything. But only with software decoding, no hardware acceleration!
Hardware acceleration is only possible for certain formats. You even said that yourself: Snapdragon is cabable of decoding H.264/MP4 with the right software. But nothing else. Same for Tegra, iPhone and all the others!
That means even IF HTC had enabled 720p support, we would still have to convert the videos. Exactly what I said above. So please, next time, think before you post, instead of mixing everything up.
You guys are mixing everything up! I really don't know how to explain it any clearer.
I'll try one last time:
Okay, first of all: You have to distinguish between software and hardware decoding.
Every CPU can decode anything via software with the right codecs. That's what programs like Coreplayer do.
BUT: Software decoding is slow. Much too slow for 720p HD video.
THUS: 720p playback is only possible with hardware decoding.
Snapdragon, Tegra etc. support hardware decoding of 720p video.
BUT: Only for certain formats and only with the right software.
THUS: If HTC would provide the software, we could play 720p video like the Acer Liquid.
BUT: We would still have to convert the video files! (same for Acer Liquid, iPhone etc.)
THUS: The 720p playback capability would not free us from having to convert the videos!
THUS: The only advantage would be the ability to play 720p video on a TV.
BUT: Our HD2 does not have TV out.
THUS: 720p playback capability would not help us at all. We would still have to convert the videos and we would still have no TV out.
Okay, I think this is as clear as it gets. Got it now?
This thread made me lol
Personally I want my phone's battery to get hot enough for use as a hotplate.
There isn't a technical reason not to un-enable this non-feature, so HTC are stupid and m$ is evil.
F.Y.I Macbooks can do this since 2006 so don't say I'm uninformed

No, I'm afraid you're the one who is mixing things up. It is indeed the situation at the moment is that only certain video player applications can make use of hardware acceleration on the HD2, and that those applications are only capable of playing a limited range of video formats. You make the mistake of assuming that, because this is the case, there must be something about those video formats which makes it inherently easy to play them with hardware acceleration, while it is inherently not possible to play any other format that way.
That is not true. There is no technical reason why someone cannot make a video player app which can play back any video and take advantage of hardware acceleration while doing it; the reason this hasn't happened is because of a combination of money-grubbing, selfishiness and incompetence on the part of Qualcomm, HTC, Microsoft, and a few other companies too.
If either Qualcomm were to release full details of their hardware, or HTC were prepared to spend a little more money, someone would then be able to write a video player app which could play back as many formats as Coreplayer and use full hardware acceleration while doing it. Whether that theoretical application could play back 720p video smoothly is another question; but I wouldn't be surprised. Assuming it could, such an application would require no conversion of 720p material to play it.

I don't know what seed_al was talking about.
I can play 720p video on my Touch HD (not HD2), but the performance is terrible.
If CPU is powerful enough, and software can utilize the GPU, playing back 720p (.avi) smoothly on a phone is possible for sure.

[Q] Possible to mod the camera to record in 1080p ?

Any devs looking at the possibility to record movies in fullhd, 1080p ? I seem to remember I read somewhere that it should be capable of it.
Well if it is capable of recording in full-HD then why wouldn't Samsung themselves implement it so to make more sales?

Exactly my point, there could be a thousand of different reasons. But maybe our devs inhere are a bit sharper than Samsung themselves...
People have made mods that claim an extra 20 - 30 megabytes of RAM. When these are applied problems are noticed with 720p recording. Imagine the ram usage for 1080p. I don't think its worth the hassle.
1080p used in mobile phones do you think will be much better?
come on!
i dont think so...
Especially since the audio is still bollixed... if they fixed that first.

Dont think it need it.
First if hardware permit to record 1080p stream the 5megapixels chip wont manage to provide 1080p frames with a decent framerate.
then if it could the optics wont be able to resolve the resolution gain.compared with n8 nokia or iphone 4 720p output you can see what there s place for improvement in this way(sharpest optic and better sensibility)
but may our dev can work on compression level to keep more fine detail , sensibility management or faster autofocus without resolution change.
think this is the only reasonable improvement we could expect by software mod
Well, I have problems with 1080p playing, let alone recording.
Anyway, the hardware is 100% capable of 1080p recording and it would be really cool if some can mod it.

Hummingbird is capable of 1080p hardware decoding/encoding. It's equipped with hardware encoders/decoders. Both of them require decent amount of RAM reserved. I think that was the issue.
5mpix sensor is perfectly capable of delivering decent framerate @720p, why wouldn't it be capable of 1080p?
Resolution is enough, there might be bandwidth limiting factors between sensor-CPU.
Optics is perfectly capable of making quite sharp photos @5mpix, why wouldn't it be capable of shooting just 1920x1080?
There will be no software mod enabling 1080p recording, without hacking into hardware codecs/drivers.
Even if the framerate would go down to 15-20 fps, I would personally really like this feature. Some moments are best captured in highest resolution possible. An idea about the memory could be to allocate needed amount on demand, thereafter releasing it again?
Thanks for confirming that our Galaxy S is indeed hardware-wise capable of recording in 1920x1080.
Actually, why 1080p? It doesn't NEED to be 1080p. Why can't we add support for 800p (800lines vertical res) or even 960p.
We keep thinking about making the jump to 1080p, but is there any reason why would couldn't ramp up the resolution higher on the camera? Just because your TV expects 720p, doesn't mean computers do when playing it back...

800p and 960p are not common, so it would make things awkward. Can't play it on a 720p screen and not properly on a 720p screen.
BTW although noticable I don't think the difference between 1080p and 720p is that big. So I don't think anyone would really notice the difference between 720p and 960p and if so probably more as a placebo than a real difference.

I agree on the odd formats. However, going from 720p to 1080p is a significant improvement, especially if you have a large ( 46" + ) flat panal to view things on.
I would be very interested in this. And for everyone saying its not needed, this is a development forum. Many many many things that are done are "not needed" but still pretty cool. He asked if it could be done, lets stick to if it can, not if it should.

720 from 5 meg camera is already seriously pushing it, almost hack wise. Normally only 8 meg cameras should support it. And im not speaking about 1080...
The sensors usually can't deliver 30 fps at 1080p even if the hardware can encode it (which ive seen no tech specs of,just various "web claims" aka moot stuff)
It's not because its a 5MP sensor etc, its about how much data can go through the sensor after it's captured (that's before the CPU/DSP!!) You have very good 5MP 1080p cameras, because the sensors can handle it. They also cost more. I highly doubt the one in the SGS can handle much more than 720p at 30fps.
i'd rather have the image processing improved than 1080p, since 1080p (if it could be done that is) will be approx the same quality as 720p, use twice the space and need twice the power to decode on other systems.
in fact even the encoder can maybe be optimized. i'm not familiar with the hummingbird, but the OMAP's have TI's own such hardware codecs and while its proprietary you can implement your own codec accelerated by the DSP.
HummingBird's codec produce "very average" 720p H264 mainline (i believe?) at 10-12mbits (!)
Compare with x264 4mbit 720p H264 high profile quality for the same source, it blasts it away quality wise and is 2/2.5x smaller in file size. besides it has a zillion options depending if you want quality, latency etc.
bottom line, if a genius would accelerate x264 via the DSP it would be awesome.
I know the x264 team worked on the OMAP DSP with little success, mostly due to rather cryptic documentation
There are plenty of PC displays which AREN'T 1080P (only cheap ones). 1080p and 720p is optimal for TV's, but not computer displays. There are plenty of computer displays which are 1200 lines vertical resolution.
And I've found a difference between 720p and 1080p, but it's more obvious on larger displays which supports higher resolutions
I'd rather have slow-motion and a proper app that enables video editing/cutting/sound mixing just with Iphone 4.

I'm inclined to agree, theres room for improvement at 720p, its like the same logic as low end cameras and camera phones alike ramping up the pixel count doesn't directly mean better quality..
Plus the phone although it should be able to currently doesn't like playing back 1080p videos...
I'm not saying everyones going to want to watch 1080p on an 800 x 400 panel, just saying you might want to play back what you've just recorded to see how its come out..

[Q] 1080p mkv/ts/m2ts refusing to play

so here's my issue. it seems the video player itself has issues displaying 1920x1080 video. 1280x720 works fine, same video. same bitrate, same everything. this seems crocked.
do we know of any workaround for getting a 1080p to work. i've heard of people pulling it off, but i've spent three hours on this and i really believe it to be the player. i've tried third party clients and they're about 5fps. it's irksome.
help plz?
You know we have two different video players right? We have video player, and we also have movie player or something else like that. Try it.

What do you expect to get from playing such large videos on the Cappy? I transcode mine to 720X480 in .mkv and they are simply stunning with zero playback issues. The Cappy supports the low end HD resolution of 1280X720, not the Blu-Ray rez of 1920X1080. And it supports that rez in shooting video so that it can be played back on a larger screen. There's no benefit to playing back videos that size on the device. Resize them, you won't notice any difference in picture quality and you'll save a ton of storage space.
I have 315 bluray movies half are 1080p other is 720p so half of my media is watchable on my cappy and my tab. I use Tversity to stream to my ps3 and everything but if there was away to make it only transcode 720p to mobile devices or have a player that will resize it for us that would be awesome.

May be more of a codec problem than anything else.
While I never put anything bigger than 720p on my phone (since 1080p has no appreciable visual increase in quality on the phone screen, but a MUCH larger file size), I definitely have played 1080p on my phone before. Hence why I think it may simply be that 1080p MKV w/ certain codecs might not work. Remember that media files *legally* downloaded from the internet will often have slight variations in the parameters used when converting to MKV w/ x264/VC1/etc codec. Hence just because 2 files are "720p x264" in a Matroska container doesn't mean they are actually identically encoded. And the Galaxy S can sometimes be a bit picky about what formats it "automagically" supports and which it doesn't.
And by the way, as you clearly noticed, the "Video Player" app in Android is the only one to use the GPU to accelerate video playback. Other apps might work, but they will run the CPU way harder, and give you worse battery life. Monitoring the "time_in_state" to see what the CPU is running at, I can play 720p x264/MKV files with the CPU at only 400 MHz. Obviously, sometimes the default player won't play what you want, but it's much better to use it if at all possible.

This is the main reason I stick with the built-in player. I was on a flight from Ft. Lauderdale to St. Louis to L.A. on Tuesday and I watched 3 movies of close to six hours total length. Landed in L.A. with 31% battery still remaining.
my reasons for wanting to play 1080p is irrelevant to the scenario, i'd just like to see it done.
i considered a codec issue shammy, but i extracted a 60second sample from my crank copy and left it in 1920x1080mkv and tried it. no dice. i handbraked it to 1920x1080mp4 no dice. i once again handbraked it to 1280x720mp4. worked fantastical without any change in any settings except res. hence why i think its a limitation on res rather than codec/bitrate.
i am just IRKED all around at this. time to hit the irc and start screaming at people until somebody gives me an answer huh lmfao

How do you lose quality by resizing for the device you'll be playing on? All those extra pixels of HD resolution on a 800X420 screen do not yield better quality, they just require more CPU/GPU to process and more storage space. Nothing is gained by playing HD-sized videos on the Cappy. Absolutely nothing.
I own a small HD video production company in L.A., but don't take my word for it.
I was talking about playing the same media file from my Ps3 on my tv. I'd rather not convert my 1080p files to 720 just for my hand held I'd rather have a better way to do all of it using the files I currently have. Tversity works good but not perfect for over 3G but when I had my iPhone it would play pretty good using airvideo over 3G but there has to be something to make it all work

It would be nice to be able to do this I suppose..but if you don't mind...Why ?
If you play it on any other thing but your phone..you will not really benefit from having it this way..and also..you won't really have enough storage to hold it to be able to watch a full featured film.
Until Samsung gets off their asses and fixes the issue with making the usb-hdmi cable you will never get the output capable of seeing any difference than what you can easily do right now at 720p...If you want to ***** about something...that is what I would ***** about..They had those cables available for 1 month..and not many was ever shipped out to the stores when they introduced the phone...I've e-mailed them every week since October and the only reply is they are working on it...so...I'm not holding my breath on seeing it anytime soon since they are working on the next line of phones already..

How about I send you my 12TB of video and you can convert it all into 480p, would that suffice for you? since you have such an issue with what I do with my device and provide absolutely no helpful solution, you do it! I sure hope you have couple dual 12core opterons sitting around, because it's gonna take you awhile. currently, encoding crank.mkv time remaining: 1h5m. now realistically i'd never convert my entire collection, just whatever video I want to watch at the time. but guess what? When i'm leaving or doing something I do not have an hour to wait. It's almost faster to download a 480p copy, you realize that right. converting while dealing with 1080p is not fast, nowhere near it. I find it unlikely you have any experience in the matter, i'm sure i've put more time and effort into this than your useless 30 second out of line response, so "chump" take the attitude and leave my thread please.

i started with 1920x1080 crank 60s sample gone through handbrake reducing it to about 6mb.
1920x1080 through
1282x726 do not play. at all. unknown file.
1280x720 and below play without issue, and play damn well.
the file is exactly the same codec and container, just resized. so i believe it to be an issue with the player.

Could it possibly be that your video is simply beyond what the player and/or the device is designed to handle? Square peg, round hole, I say. 1280x720 is indeed within the scope of the HD specification, so there is no fraud in saying the device can play HD content. It just can't play the high end of the HD spectrum. Live with it or get another device.
He's just trying to find away to not reconvert 3,000 hours of videos... if there was away for the computer to transcode to 720p to the device but leave it 1080p for the ps3 but not make 2 files for one video.... how hard is it to want that??? Tversity works for that but it don't detect the device as a mobile device that wants 720p it either does 1080 or goes way low and looks like crap... we want it to do both 720p for they device Ans 1080p for the ps3 at the same time.

I understand that, but it's like complaining that his old tube TV won't display HD signals. Or that his DVD player won't play BD discs. It just wasn't designed to do it. For a device to transcode 1080p to 720p on the fly would require a lot more horsepower than what the Captivate has under the hood. Accept and move on.
First, I understand why you want this; it's a matter of convenience and I don't blame you.

It may be the same codec and container, but what is the bitrate? A lot more data may have to be pumped through the i/o system and larger frames are going to have to be resampled. I'm not saying it is impossible on the hardware, but it might be. I seriously doubt that it's just a matter of some bug, oversight, or intentional disabling of 1080p without good reason.

Can the Nook Color play videos encoded in 1024x600 and 2,000 kbits rate?

Now that I heard you can put Honeycomb 3.0 on the Nook Color, I am thinking of getting it today at B&N.
However, I will be using the device mainly for watching movies and I love to convert movies. I will be converting 720p .mkv movies to .avi format with 1024x600 resolution and 2,000 kbits rate to get the best video quality.
My question is: Can it play .avi files with 1024x600 resolution and 2,000 kbits rate super smooth on Honeycomb?

So that would seem to be a significant barrier to your plan ;-)!
In the basic 2.1, the recommendation is for MP4 (H.264) at 1,100 kbps. I recently watched Inception at that setting and it was perfect for the Nook Color.
Check out this thread regarding Handbrake settings for the Nook Color: http://forum.xda-developers.com/showthread.php?t=894165
for any kind of hi-res content, you'll want to use hardware accelerated playback. Unfortunately, the chip in the nook only supports a certain video codec and resolution. h.264 basic profile and a max of 800x480. 1100 kbps looks pretty good.
Any other codec or higher resolution will rely on the software renderer, and it will be very choppy.
I created a nook color preset for handbrake you might find helpful. It will convert your 720p movies to the highest quality the nook supports.

You guys just burst my bubble. If the max resolution that it can play is only 800x480, then I guess I will not be buying the Nook Color. Even my HD2 can play mpg4 file that is encoded in 800x480 with 2,000 kbps smooth as butter without problem. If the NC cannot play 1024x600 with 2,000 kbps, then what is the use?
I guess I will have to wait for the Xoom to come out.
800x480 looks great. The nook scales it up to 1024x600, and the pixel density is high enough that you see no pixels. It looks very smooth.
You do realize that the hd2 has a 1ghz snapdragon processor. While we only have an 800mhz stock that can be overclocked to something equivalent. Why would you expect it to do better than the hd2? I would say they would be the same. But if the difference is worth the extra $350 premium then go for it. 854x480 at 1100kbps looks amazing on the nook.
The biggest dissapointment with my Nook is the video playback. Its not horrendous on eclair, but I have absolutely no luck with it on these froyo builds. Probably going to go back to 2.1 soon just so I can at least view some videos again.

I never thought of owning the Nook Color until I heard about being able to put Honeycomb on it. I prematurely got excited and thought that it can do good video playback since my HD2 is excellent at playing 800x480 file at 2,000 kbps encoding. I knew that it can be overclocked to become more powerful. If it can only do 854x480 at 1100 kbps then it is a big disappointment. Beauty is in the eye of the beholder. If 854x480 at 1100 kbps looks good to you, it may not look good to me because of possible pixelation. I want a device that can play full screen resolution with high bit rate. I know that it would require bigger memory card/bigger storage space and slightly consume more power but that is what I am willing to sacrifice.
Well, I guess I have to get either the Xoom or the G-Slate. I don't mind paying extra for it. Just put in some extra work time and I will get a device that I will be happy with.
I love gadgets and love to tinker with them and that is why I enjoy putting all kinds of available OS onto my HD2. I was just about buy the NC just to tinker with it but I guess I will wait until the great people at XDA can somehow get hardware video acceleration on the NC to be able to play videos at higher settings.
Thanks for all the info about the nook's video capability. It was very informative.
DSP support?
What are the chance the DSP will get supported in Froyo/Honeycomb?
So even with hardware acceleration we only get [email protected]

Video quality
Any idea if this would work better if the nook was oc'd to 1.1, I guess once the dsp is fixed maybe that and a 1.1 cpu will work.
While i do lov to play 720p videos on my captivate (its screens is 800x480) it is down scaling those videos... the main reason i do 720p is because thats what tubemate will let me download them as and still work..
That being said he 480p that the NC can so is still a very good picture.. Normal CTR TV's are only 480i dvd's are at 480p and they still look good on my 42" 1080p tv.. not as good as blu-ray but still good.. and thats stretched to 42" were talking about 7"
1080p 42in= 52.45 DPI
1680x1050 20in monitor= 99.06 DPI
NC running 800x480 at 7inch= 133.28 DPI
NC running 1024x600 at 7inch= 169.55 DPI
Now.. looking at those numbers.. so you REALLY need to run at 1024x600? even at the 800x480 your getting less pixelation then you do on a 42inch 1080p tv.. yes the NC is held ALOT closer.. but even so.. its still giving you DVD quiality picture in your hand on a 7inch screen..
The video playback is definitely disappointing. It sucks not being able to just download a video and just watch it.
I'm getting a bit lost from the conflicting opinions. I'm a lazy and VERY not fussy video viewer. My main use of my NC is to watch videos that were originally made for an iPhone.
Bottom line... Now that sound is working in honeycomb to the NC. am I going to be able to watch my simple iphone type videos on my NC if I take it up to honeycomb? Remember. I'm not at all fussy about quality as long as it isn't too terribly jerky.

From what i understand (and thats not much =) currently honeycomb still has NO hardware acceleration for video.. nither does froyo so the best video playing on a NC you can get is currently running a rooted stock rom.. encoded at 800x480 or below.. the iphone 3gs and older all have a screen size of 480x320 so they SHOULD work as long as they were encoded properly (right codec and such)
Although I understand the excitement, this seems like a very premature discussion. Despite the repeated statement that honeycomb is available on the NC, out is in fact not. What you are seeing is actually an SDK build. Software Developers Kit. For development. And the first SDK at that. You are essentially seeing an emulator running on the nook screen.
Before everyone goes nuts I know that is not technically correct, but it is as correct as saying we are running full honeycomb.
After an AOSP build is released we will see a more functional version and eventually probably see better integration with the video hardware. And for my final rain on this parade...I am a professional video content creator. And if you think you are able to see the difference between DVD quality and 2100 stream HD on a 4.3 inch screen, you are mistaken. Or have vision above that of mortal men.
For the record I owned an HD2, now use the Evo and also own a NookColor.

ANYWAYS the dvd quality vs 2100 stream HD by that do you mean a 2100/kbps steam?
if thats the case then its not a surprise seeing as 2100/kbps is enough to stream at 480p.... which is dvd quality

OP's original question was about "I will be converting 720p .mkv movies to .avi format with 1024x600 resolution and 2,000 kbits rate to get the best video quality."
Later after some responses he comments he gets better resolution on his HD2 (that is a 4.3" screen) so he will skip the nook.
You still point out a misunderstanding I had now that I go back which is that he is starting with a 720p source but ending up 1024x600. But really this is just makes my point stronger because then we are looking at an even smaller difference in the resolution.

[Q] Resolution Question

Hey, I'm about to buy a chromecast, but there are something that stops me. If I have a phone with quad hd resolution, does it stream in that resolution on the tv, or does it stream up to 1080P?
Another question is, is there any known issues with the chromecast? I just want to be sure.

Well you can't tab cast from your phone. It streams directly from the internet and doesn't display mirror. So it will stream whatever the source content and your TV resolutions are.

Another question is, is there any known issues with the chromecast? I just want to be sure.

Quad HD? Like UltraHD (3840x2160)?
Casting local media directly (via Avia, RealPlayer Cloud, or Allcast for rooted Chromecasts) is as-is, no conversion of the media happens, and Chromecast will play the media if it is capable of decoding it.
I don't think Chromecast can decode UltraHD as it tends to have trouble with 1080p and high (>10 Mbps) bitrates, but I'm not 100% on that. I can use AllCast to send a 1080p video I shot on my phone, but there's a little bit of pause now and then.
As far as known issues, some old TVs that report 1080p support but don't actually display correctly have trouble. Some Yamaha receivers are having some trouble with the latest firmware.
Most other issues are either in progress or have already been taken care of via updates on the application side.
A tiny number of reports of Chromecasts being "bricked" but probably normal or better for the number of Chromecasts out in the wild.
There is a phone with QuadHD resolution?!??!??!??!? LOL
There is a lot of Misinformation regarding resolution in the Phone business I assure you...
Cameras that say they shoot 1080P in most cases don't. The Chip (CMOS for the most part) does not have a REAL 1080P resolution. What it does is take the native resolution of the camera (usually much lower) and SAVE THE FILE in 1080P by simply upconverting it.
And Upconverting doesn't ADD resolution or Quality it just doubles the size of each pixel to fill in all the pixels of the higher resolution.
You may find a phone or Camera that says it supports 4K but in truth it is not a REAL 4K! The File will read and display on a 4K device but your not really getting the FULL RESOLUTION a 4K video has when captured natively in a TRUE 4K.
The Chips that receive the image from the lens are not large enough to do a true 4K. It is merely upconverted when saved to that format.
Like taking a single pixel and repeating it 3 more time to make a pixel 4 times the size of the original where in a REAL 4K each pixel can be different and rarely are the same (maybe similar but not the same)
Now these chips are improving by leaps and bounds so in time they may even do these resolutions for real...But by then we will also have things like 16K because the bigger cameras with have 3/4" and 1' CCDs or CMOS' will advance from the technology as well.
I'm sorry regarding quad hd, english is not my first language, and when I meant quad hd, I actually meant 960x540. I know alot about resolution, but I didn't mean 4K. Before 2K and 4K, there was quad hd as 960x540.
I have good internet, so I don't worry about that.
Thank you all for your answers, I'm going to buy a chromecast when I come home.

Ahh, I see qHD from the computer realm. Thanks for teaching me something new! :good:
I have some VGA (640x480) videos and from Avia they play picture-boxed (black border on all sides, because Avia does not alter the video). So it will likely depend on what application you use and what Chromecast decides to do in terms of scaling, if it has any (I don't know).
I think the biggest reason it can't do 1080p natively is because it's wireless G. I can only hope Google decides to release another chromecast or something else like it with wireless AC.

It's wireless N which is more than adequate. It depends more on latency and bitrate of their media compared to that processing power of the Chromecast hardware.

It can't do 5GHz, and its horrible at streaming HD movies from Google Play movies. You mention processing as if the Chromecast is transcoding. None of this would be a problem if it could do 5GHz and had an AC chip.

Edit - My Samsung UN46F6300 is also terrible at streaming HD content over it's Wi-Fi (also 2.4GHz), but connecting the tv's Ethernet to my WD wireless AC bridge alleviates all this.

Yes the 2.4 GHz band is not optimal as it's crowded but latency issues aside, it's fine.
The hardware still matters because most hardwareand appliance-oriented decoders have limits to the maximum bitrate it can decode due to buffer and memory limits.
It's much different to more general CPUs which can allocate more memory and have more CPU power to adjust.

Well I'm pretty sure GPlay does some transcoding but not 100% sure. In any case If the unit is having issues playing the video over 2.4Ghz the issue is really the Video Bitrate needs to be lowered enough to stream without issue. In the end no one is getting full HD 1080P on any device over ANY wired or wireless network because Full HD uncompressed has a Bitrate of over 1.49 Gbps. Far beyond standard Ethernet standards which is why we use Fiber Optic for broadcast and even then we compress the hell out of it before you ever see it.
So pretty much all HD we are playing is not really full HD.
Can you play 1080P locally?

Ahhh no Problem...You meant quarterHD actually...
You wouldn't have confused us if NHK and a Consortium hadn't actually invented QuadHD for Broadcast! bhiga and I both work in broadcast and were recently talking about it.
Well, I forgot that it was Quarter HD, but it's okay now, since I have aleardy ordered it. Again, thanks for your help guys.
