Is anyone having problems with video playback?
WMV files they are played very slow (loosing a lot of frames). With MP4 I got best results but not the best. Any suggestions??
Thanks
WMV
I can't even get the above files to play
are you using Media Player? as video playback has always been awful on Medial Player on every pocket pc or smartphone ive everhad.
install TCPMP and video playback will be perfect, and will play any file you throw at it

Thanks for the tip keyz86. I'll try it.
no problem, glad to help a fellow Dimondarian
won't play
loaded the TCPMP but everytime I try and start it i get the attached error, using diamond help

Dimondarian Cool hehehe
Has anyone been able to play a full resolution file without skipping?
I am using CorePlayer now but if another player works better, please say so.
With Coreplayer I benchmark about 85%, which is not good enough.
I believe the Diamond should be able to get 100%.
I found that an encoded mp4 file would play about the same as the original avi xvid file...
What do you use to encode videos specifically for the Diamond?
Come on!! Post your results!

What video settings do you use with coreplayer ?
DirectDraw, GDI or what ?
This is what i get:
With these configs.:
But with some other videos i have i get only 88% speed and some frame drops and tearing.
Doesnt the Diamond has a good video hardware.
Imo, it shouldnt lag at all.
Ive read somewhere that it doesnt use the hardware correctly since the drivers were not fully implemented. Not sure if its true.
Still looking for a good solution... any more help?
Coreplayer is still choppy ...
Yeah, I wasn't able to get WMVs to play using this, either.
I think what we need to have a look at is which encoding, resolution, bitrate, fps, etc are optimal for the diamond using core player.
I'm experimenting a bit. Will report back in a bit...
I've just got my Ignito (diamond) a couple of days ago, but I've got a long history of video playback on hand helds. Since this is my first time post, and I happen to have a bit of time on my hands.... I'm going to convert a file into a series of different resolutions and settings to see which one will perform the best. I know the objective is to get a full res one to play, but I'll see what I can come up with.
Also, I'm using the default ROM at this time.
With Coreplayer you should use the 'QTv' display option - this is hardware accelerated and beats 100% benchmark on every AVI I have tried. If you get a blank display using this mode, you are using an old version and need to update.
Alright. After trying a bunch of different codecs, encoders, video and audio formats at various resolutions I came the conclusion that for now, full resolution video is just not possible without jerky movements during continuous motion or fast action scenes.
My eyes are very sensitive and I get really irritated if playback is not perfectly smooth.
So far what works the best in achieving this kind of natural playback is AVI as the output container with XviD video codec at 480 x 360 resolution, and mp3 audio. I set the video and audio bitrates to match whatever the source video was (min 864 kbps and max 1008 kbps for video and 192 kbps for audio).
Even then, CorePlayer is a must with the following settigns: QTv On, TytnII driver mode On and Smooth Zoom On.
Every now and again CorePlayer will show only a purple screen during playback when QTv mode on. At that point I usually do a soft reset and it starts working again.
This issue may be resolved with an upcoming release of CorePlayer (1.3) but until then, the solution above works exceptionally well.
I'd be very interested in anyone else is having success in other ways...
320 by 240 versus 640 by 480
I have done some playing with conversion and have found that the Diamond (currently) does not support the 640 by 480 settings with a good bitrate. The BEST conversion I have found (using Coreplayer to play back the files) is using the BETA Version of the Pocket Divx Encoder (http://www.pocketdivxencoder.net/EN_index.htm) and using the HTC Diamond Template (NON VGA!!!!, there is a VGA and non VGA) that team has developed. They have done an excellent job!
The output settings -
Dimensions 320 by 240
Video Quaility - "36" ... 584 kb bitrate
Hopefully an update by HTC or coreplayer will be released to fully utilize the resolution that the Diamond SHOULD be able to support, but for a clear, non jerky playback, this is my 2 cents
im able to play those axxo dvdripson using coreplayer without any sort of convertion....
I want to share my experience. I am using core player and trying to recode unprotected high-definition TV shows (original resolution of 1920x1080) that I've recorded on Windows Media Center (.dvr-ms files) to watch on my Sprint Diamond. Unfortunately .dvr-ms are poorly supported, and the only program I've found to recode is TMPGEnc 4.0 Xpress.
I am using Core Player version 1.2.5 build 4506, and my video output is QTv Display with the Tytn II driver mode enabled.
Like everyone else here, I have had horrible results when converting the shows to DivX at 640x360 at any usuable bitrate (above 500 kbps). Benchmarking in Core Player yielded a playback speed of 66% or so (completely unacceptable, obviously). So I played around with the resolution and bitrate, and finally settled on the following:
Format: DivX
resolution: 512x288 (maintains the 16:9 aspect ratio of the original)
Video bitrate: 850 kbps
Frame rate: 29.97 fps (progressive)
Audio: MP3
Audio bitrate: 80 kbps, 48kHz sample rate
With those settings, I have a 104% playback benchmark with around 25 dropped frames compared to several thousand played, and about 29.5 fps. Basically, it is completely smooth audio and video.
I was still PO'd that I had to sacrifice so much resolution and bitrate on a supposed media device, so I played around with other formats. WMV was awful. MPEG-2 was awful, and avi was passable, but no better than DivX. I also decided to try h.264 (MPEG-4 AVC). Here are the settings I used:
Video Format: MPEG-4 AVC (saves as .mp4)
Resolution: 640x360 (still maintaining the original 16:9 AR)
Video bitrate: 1000 kbps
frame rate: 29.97 fps (progressive)
Audio format: AAC
Audio bitrate: 96 kbps, 48kHz sample rate
Core Player absolutely choked on this. It was unwatchable, and the benchmark revealed a playback speed of 50%. Dropped frames were higher than played frames (!) and framerate was 13 fps. Obviously not successful.
But, before I deleted the file, on a whim I decided to try Windows Media Player and...it was completely FLAWLESS playback. Absolutely beautiful, smooth motion, no audio stuttering, slow and fast pans were the best I've ever seen on a WM device.
Why??? Is there something I'm missing about this that someone can elaborate on? Is this the fabled "hardware acceleration" that I've read so much about? I should note that WMP had a hard time on a 320x240 .wmv file, so I can't really understand how it is able to play a 640x360 .mp4 file so smoothly. In any event, I have found my perfect file format, and, surprisingly, it doesn't involve Core Player in any way.
-R
The thing is that HTC didn't release any kind of SDK for Diamond or Touch Pro and companies like CoreCodec have hard time trying to figure out how to use the HW acceleration but they are trying very hard to improve the situation so maybe with time they will be able to use the HW for now the only way we wan't to watch videos with HW acceleration is only WMP which means recoding or atleast remuxing files.
Cheers
P.S. Could you post exact specs of the .mp4 file? What kind of AVC it was and things like that.
in regards to the WMP hardware acceleration.
is it better on battery life than having coreplayer trying its hard out to render a video. even if its a small 320x vid that plays at 120%. Does that mean that the cpu is running near max?
H.263 / 3GPP2 / MPEG4
Which one is best to use to record video?
I am not really concerned about life size, but smaller can't hurt.
I am mainly looking for :
1) Smoothness in the recorded video when played back.
2) Highest quality.
Also, is CIF resolution the highest the phone supports?
I have a Sprint Diamond running Juicy 2.5
I see everyone voting for MPEG4, why MPEG4? Any insight on that?
best quality/low size. playable on most things. newest codec.
where you got 3gpp2 on diamond i have only two options
Hey, I'm not getting my TD2 before mid-June, but I'd like to encode some videos beforehand. Since I don't have a device to test them on I'd really appreciate if someone could download this clip and test it on your phone.
Video is h.264 and audio is AAC. I heard only WMP supports hardware acceleration, but if you have Coreplayer also I'd like to hear some results from there as well. Video bitrate is only 750 kbit/s, as I wasn't sure how high a bitrate the TD2 could handle. For some reason the motion isn't completely smooth the first 10 seconds or so, but never mind that.
The file:

There is a 10 download limit on rapidshare, so I'd appreciate it if only people that intend to help me downloads it
edit: I know there is an "HTC Touch HD encoder"-program, but it produces absolutely horrible video quality at the same bitrates
I saw it on my D2, and I have to say it didn`t go so smooth as I expected.
When there is a lot of action on the screen the phone can`t keep up with the video. I presume the quality is to high for the phone.

Okay, thanks
Guess I'll have to wait until I get my phone then so I can tweak the encoding settings :/

I tried it and it just showed a solid green colour for the entire video. I guess I don't have the right codec or something. I don't have CorePlayer though.
I had the same green screen using the htc default .mp4 player on my TD2, but the file did play with The Core Player....the video stuttered quite badly in places and the audio went out of sync..I transcoded a movie using Touch HD Video converter see thread:

Hello Community,
so I gat the following problem:
The phone should show and record 1080p and 720p videos. No problem with recording, but I gat a problem with playing a video. Every 1280x720 / 1680x1050 / 1920x1080 video is constantly laggy, but the sound works perfect.
640x360 videos are working perfect, no matter what codec.
The sample videos in 1920x1080 are working perfect, so I think it's a problem with the codecs, but all videos are H264, so what's the problem here?
I hope you can help me!
Thanks,
Max
ps: found no topic about that thing, I hope it's not already existing!
I think tegra 2 doesn't support it (yet?)
Sent from my Optimus 2X using XDA Premium App
aren't they in mkv container? if that's the case, then it's normal... no mkv support yet
sorry but you both failed at my answer.
The LG P990 does support 1920x1080! As I mentioned above the sample videos are working perfectly, but other videos in 1920x1080 are laggy , even when it's the same codec, so what's the problem here?
what do you mean with mkv container?
For all who have the same problem:
I gat the answer now:
The H264 Profile of the video files must be baseline, otherwise your video will lag
You can convert to h264 baseline for example with the program SUPER
Regards,
Max
the problem is the encoding profiles used to create the videos you try to play
You dont mention where these videos come from or if you encoded them yourselves, but video are much more than just the codec.
When videos are encoded there are many different encoding settings that can be used, settings like bitrate, resolution, macroblocks, cabac, reference frames, b-frames, etc. etc. - for H264 these different settings is arranged into something called profiles and levels. Levels go from 1 up to 5.1 and profiles is called baseline, main and high
Each level and profile describe the set of encoding settings that can be used.
Read more details here:
http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC
Different types of content for playback on different kinds of units allows different profiles and levels, like HDTV specifies a maximum profile level to be used and Bluray another maximum profile level to be used. The idea is then that manufacturers of Bluray hardware decoders design their hardware codecs to support up to the maximum profile level for Bluray (which is High L4.1)and the content creators can encode their Bluray videos to the same specifications and thereby ensure that the content can be played on Bluray players.
The Tegra2 chipset support recording and playback of content up to 1080p, but that is only a specification of the resolution - you also have to know which maximum profile levels of encoding specifications it support before you can encode video properly for the Tegra2 chipset. And since it isnt designed for Bluray but for mobile use, it doesnt support the same high encoding specifications as Bluray but only a lower profile level.
The maximum supported profile level for the Tegra2 is 1080p Baseline L4.0 or 720p Baseline L3.1
If you download pirated HD movies, then most of these are encoded with similar or even higher specifications as Bluray movies - these will not play on a Tegra2 chipset.
And if you encode yourself, then you have to ensure that the settings you choose in the encoding application does not exceed the specifications supported by the Tegra2 chipset.
In short - if you download movies you can never be sure it will play because you have no control of how it was encoded. If you want to make sure videos will play, you have to encode them yourself and make sure to use the correct settings.
The videos you have that doesnt play right, will have to be reencoded with correct settings to play.
Edit: I see you found an answer while I was writing this
thanks for the answer
just something to add: The baseline things just getting important when the resolution is higher than 640x480 , my LG P990 can display all videos with all codecs and baselines with 640x480 but 1920x1080 for example will lag So these films are not a problem, because mostly they are 640x480 for mobile phones and not higher, that your Card isn't full with 2 vids
so what program would be best to convert a video to, as stated above :-
The maximum supported profile level for the Tegra2 is 1080p Baseline L4.0 or 720p Baseline L3.1
I normally use Total video Converter but cant find any of the L4.0 ect setting on it.

Hi Guys,
Most of you with a Xiaomi Mi 9 must be aware you have the ability to manually set the video compression from h264 or h265 within camera options.
As the Mi 9 can suffer from frames dropped and judder at 4k 30fps which codec is giving you the best overall performance
Ive upload a sample on youtube using h265
https://www.youtube.com/watch?v=r_RQy9XICiw
i use h.265 but bitrate remain the same at h.264 so doesnt make sense why bitrate is not lower with h.265. biggest difference is in 60fps where bitrate is the same on this phone for 30fps and 60fps so h.265 works better at 60fps since average bitrate its dealing with is lower.
