How Nook's video capability? 720 RMVB? MP4?

I am wondering how good the Nook's video capability. It seems there is no powerful display adaper driver for it?
How about 720p video support?
Thanks

720p is probably out of the nook's hardware capabilities.
Also I believe CM7 and HC are currently without hardware acceleration. Best bet is probably Froyo, but haven't tried it.

Moboplay works well for 720p rmvb. i just used real file tested

what rom you on?
i only attempted streaming with gmote from my desktop over wifi, and regular xvid avi's were pretty choppy. (running cm7)

Your NOOkcolor supports the following video file formats: 3gp, 3g2, mp4, m4v; MPEG-4 Simple Profile up to 854x480; H.263 up to 352x288; H.264 Baseline profile up to 854x480
Your NOOKcolor will not support the following video file formats: Flash (Flv/swf); Mov/qt; AVI; MKV; Xvid/divx; WMV / VC-1; H.264 Main and High profile; and videos with a resolution higher than 854x480
So far for me, 854x480 h.264 has provided the best results, mpeg4 has more compression artifacts. There's a profile posted on here somewhere for handbrake to convert to the proper format. VLC convert and stream also transcodes to h.264 if you want to stream from a media server or PC without having to convert the files.
For it to work properly with hardware acceleration, I think only android 2.1 (stock/rooted) and 2.2 have full support.

Uh if there's audio sync issues . . . how exactly is it playing videos "perfectly" ???
As has been described already, MP4 videos encoded using H.264 baseline at a resolution at or below 854x480 work well in the stock player. Beyond that, 3rd party video players aren't performing well enough for me to accept as "perfect".
I've tried Rockplayer, Vital Player and VPlayer and none of them play raw AVI files (xvid) that I watch from EZTV to my satisfaction. The only thing that works for me is to re-encode them using Handbrake and the Handbrake preset that's available in this forum with a constant quality setting of 22.

The video part of the video plays fine. The audio part of the video does not.

Don't misunderstand me, I've done my own testing. The point I'm making is if people read such statements and then try to watch videos they'll be disappointed in the fact that there are indeed sync issues.
I'd never describe the playback of a video file with audio sync issues as "perfect". IMO the only way playback would qualify as perfect is if there are no dropped frames and no audio sync issues. That's not the case in any of the solutions i've read on these forums when it comes to AVI or MKV playback.

Nook Color's video player performance is underwhelming at the moment in regards to 720p playback. I'm no sure how the Archos 70 could play it just fine.

Okay, just to clarify concerning 720p.
Nook Color has a single-core 800mhz processor.
I have found that a single-core 1.4ghz processor is very marginal for 720p - most don't work, even with the most CPU-efficient software decoding ("core").
Generally 1.6-1.8ghz is the minimum required.
So, the only remaining question is whether the graphics chipset will actually support 720p hardware acceleration through a change in the software:
PowerVR's SGX series features pixel, vertex, and geometry shader hardware, supporting OpenGL 2.0 and DirectX 10.1 Shader Model 4.1.
The SGX GPU core is included in several popular systems-on-chips (SoC) used in many portable devices. Apple uses the A4 (manufactured by Samsung) in their iPhone 4, iPad, iPod touch, and Apple TV. Texas Instruments' OMAP 3 and 4 series SoC's are used in the Nokia N900, Sony Ericsson Vivaz, Motorola Droid/Milestone, Archos 70, and others. Samsung produces the Hummingbird SoC and use it in their Galaxy S, Galaxy Tab, Samsung Wave S8500 and Samsung Wave II S8530 devices.
Intel uses the SGX 535 as its GMA 500 and GMA 600 integrated graphics for their Atom platform.

Are there manual settings that I can program into Baddaboom? I use that for video encoding as it supports CUDA on my graphics card reducing encode times up to 70% at times.

FWIW "Saving Private Ryan" as both an avi and mp4 have played just fine on my rooted NC (Rockplayer).

In handbrake, the iPod/iPhone profiles produce video files which work fine on the NC (up to 854x480). So if Baddaboom has profiles for those devices, give those a shot. If you want try to tweak the settings manually, the magic configuration in handbrake is:
Set max B-frames to zero
Turn off CABAC entropy coding
Turn off 8x8 transform
Turn off weighted P-frames

In my experience vitalplayer neon plays movies better that rock player.

THANK YOU for that! I've been using rockplayer and having a couple different problems which put me trying different encoding methods last night (different sizes/audio settings, etc, etc.)
Rockplayer is simply inferior to the V7 "Neon" version of MoboPlayer. Very excited about this software find! Thanks!
On the 720p resolution thing:
The Nook's display is 1024x600. 720p video is 1280x720. Playing 720p format videos is overkill. You can convert it down to a smaller size (working on the "best" settings right now in my "Things I Learned" thread.)
Apparently the hardware accelleration only works on up to 854X480 MAX. Anything less than this is scaled up/down to that before run through a hardware scaling up to fullscreen (1024x600).
I find for software playing (for now) 854 width is doable, but 720 width (480p) is nearly the same quality. I'm still playing with the settings, and with the discovery of MoboPlayer, I'm redoing research. I'll be updating my thread with the "best" settings the software player can handle (max 1ghz cpu overclock). Since I'm using a max of 858x480, it should play with hardware accel flawlessly once that is working on CM7 (already works on 2.1/2.2?).
Love this platform.

[Q] Mkv support ??

Currently owning a vodafone smart II (really sluggish) , and I just found out this marvelous mobile . Well that said my only concern is will it play mkv on its default player ? I double checked their site (Sony) and found none info listed. Tried google and nada nada ... Well seeing this mobile has potential would be nice to know it supports MKV natively... Any one knows something please ????

Yes it will Xperia 2012 devices already support mkv files
Sent from my LT26i using xda app-developers app

It plays MKV out of the box, but audio support may be an issues. Either way MX Player plays MKV fine with support for most audio formats.

MKV is just a container so the real question would be it's audio and video codec.
Xperia Z/ZL or any high end android phones only support H.263, H.264, DivX, Xvid, 3GPP, 3GP2 I think that should be all the video codec it support. But as the other poster said... Just download MX Video player I use that over any stock video player 99% of the time.

MKV's work, but there are limitations. You can't select what audio track to play, it just uses whatever default track there is. Secondly there is a somewhat limited codec support. Many higher quality MKV's you find in less legal places of the interwebs use AC3 (Dolby) or DTS (or their HD variants) audio codecs which aren't supported. As far as I know it'll only play files with audio in MP3 or AAC, and I'm not sure about multi-channel AAC. Subtitles won't work either. And then some MKV files just randomly refuse to play, but I haven't identified what causes that problem.
There are two solutions:
Either just play everything with MX Player, with the HW or HW+ decoders you still have full hardware support and the benefits of Bravia Engine combined with full support for pretty much all audio codecs, multiple audio tracks and multiple subtitle tracks.
The other solution is to use software to remove unused audio tracks from your MKV's and if necessary recode your preferred audio track to stereo AAC. By far the best software to do that is Avidemux. It allows you to delete and recode streams without affecting other streams. Basically that means you can remove audio tracks you don't need and recode the one you want without having to recode the video, which is extremely fast and with recent CPU's only limited by the disk read/write speed.

First off, have you ever had any video work for you? I use HandBrake without changing any default settings. I had a few MP4's that played but had issues so I just ran them through again as is which corrected the issues.

These settings were designed for the roku, but I'm pretty sure they would apply to chromecast as well, even if just as a starting point (for example, you can probably increase the bitrate):
Preset: Regular - High Profile
Container: MP4 File - make sure Large file size is checked.
Picture Tab
Size
DVD
Anamorphic: Use Strict or Loose - Anamorphic will attempt to create a widescreen effect from a DVD format.
Cropping: Automatic
Others
Anamorphic: None
Check Keep Aspect Ratio
Cropping: Custom - make sure all settings are 0.
Video Filters Tab
Filters
Detelecine: Off
Decomb: Default - this will automatically deinterlace only if needed.
Deinterlace: Off
Denoise: Off
Deblock: Off
Grayscale Encoding: Leave unchecked
Video Tab
Video
Video Codec: H.264 (x264)
Framerate (FPS): Same as source. If your source is greater than 30 and you experience playback problems such as rebuffers, change the FPS to 29.97.
Quality - You can use Constant Quality, or Average Bitrate. Experiment to see which is best for you.
Constant Quality: RF 17 to 21 should work well. Smaller RF settings will result in smaller files, but less quality. Larger RF settings will result in larger files, but better quality.
or
Avg Bitrate (kbps): Usually 1500 to 2500. For fast action videos such as sports shows, use a larger number. If your video shows jerkyness on fast action scenes, use a larger number.
Audio Tab
Audio Tracks
If your source has a digital audio track, use two audio tracks - one digital passthru, and one AAC analog. This will give you high quality audio on devices that support digital tracks, and will give you analog audio on devices that don't support digital tracks.
Source
1st track: (AC3)(5.1 ch)
2nd track: (aac)(2.0 ch)
Audio Codec
1st track: AC3 Passthru
2nd track: AAC (faac)
Mixdown
1st track: None
2nd track: Dolby Prologic II or Stereo
Samplerate
1st track: Auto
2nd track: Auto
Bitrate
1st track: Auto
2nd track: 128 or 160
DRC
1st track: Auto
2nd track: (your choice)
(From the HandBrake Guide)
Dynamic Range Compression
The dynamic range of an audio track is the difference between the softest and loudest sounds.
Dynamic range compression reduces the gap between those extremes.
•1.0-2.5 are good values to use.
•0, the default, turns it off completely.
•1.0 uses the compression hints embedded in the AC3 track.
•Values greater than 1.0 compress the range further by boosting the volume of soft sound samples while leaving loud samples as they are. This squeezes down the range between the softest and loudest parts, but should make the softer ones easier to hear in noisy listening environments.
Note, this is not the same as a gain or volume boost control.
Compatibility
Dynamic range compression only works when the source audio is AC3 and you are encoding to another format, like AAC. It has no affect on AC3 pass-through or on DTS or MPEG-2 audio.
Subtitles Tab
Roku does not currently support embedded subtitles, but you can add them for future use, or if you're going to use the encoded video on something else that does support them.
Chapters Tab
Like subtitles, Roku doesn't currently support chapters, but you can include them for future use. Check the Create chapter markers box if you want to include chapters.
Advanced Tab
Use the defaults.

I found that using "High profile" (verify 4.1 as the level under the video tab), coupled with AAC audio under the audio tab, will give me a direct play MP4 as a result. Good luck!

Playing 2D/3D video files with AC3 audio

Has anyone been able to figure out how to play videos with AC3 audio inside Gear VR? When I play such (2D or 3D) videos, the video plays fine but there is no sound and I get a pop-up that the audio codec is not supported. In non-Gear VR mode, the stock video player can play such files with video only but the BS Player app can play such files just fine with both video and audio.
Since most of my videos have AC3 audio, it is a real pain if I have to convert the audio every time before copying such video files from the PC to Note 4 SD card.
Thanks,
Osho

I have read that ac3 codec is no longer included in factory rom because licensing fees. I think the only way would be to reencode movies to files with sound natively supported by Note4

Until Oculus or another developer includes more audio codecs, Gear VR supports only AAC and mp3 audio for now.
With Virtual Dub you can easily and fast convert your movies tho, when you set video to passthrough and only the audio to convert. Takes only a few minutes to convert a movie then.

Sounds easy enough but would you so kindly post slightly more details to doig this in virtual dub? (Not a bioshock reference)

HDR10 video files playback

Is there any way to play HDR10 video files with proper HDR colors? HDR works fine in YouTube, but neither the stock player nor VLC or Kodi manage to play the video file properly; washed-out greyish colors are the result. The file is a standard 4k HEVC HDR10 24fps video, and plays fine besides missing HDR. Since the phone itself supports HDR10, I really wonder why it won't work. Is it a software-side artificial limitation to Netflix and YouTube (where HDR works just fine), or is there any technical reason behind this? And would there be any custom ROMs with proper HDR playback support?

Try mxplayer, has better support for hdr metadata than stock &Vlc

Any solution to this....?

i dont have proper information regarding the question asked.. but i felt to share my experience too..
i have VLC , MX player, KM player .. i tried playing Batman begins(2k) movie..
then VLC changed colours drastically by boosting saturation and gamma levels..
KMplayer played it in good colours, i found that something relating to SW/HW enforcing or acceleration has to do with it..
then finally i tried to disable all enhancements in VLC and tried.. then video became choppy..
it couldn't play the video at all.. same as my Laptop ( i3,8th gen - default HDgraphics) plays 4k video in choppy manner
then i thought: they are not only playing video, but converting the video while playing it.. because i can observe loss in detailing of picture ( my laptop with 1080p screen has more detailing than, phone 1080p screen)
