[Q] Video Playback CM7 - Barnes & Noble Nook Tablet

I need some help on video conversion for playback using MX video on CM7 Rom.
My question is -- why is it that when I play mpeg4 videos it will only do so using software decoding. However, when I download a test sample video in mpeg4 format it plays using the hardware decoder. Can anyone suggest a video conversion program (I'm using any video converter). Or possibly let me know what settings you or using. It is not that the videos look bad when it using the software decoding, it is more why how come it won't use the hardware decoding.
I am sure I am just missing something, but any help would be greatly appreciate.

i use format factory to convert my vids to mp4 format using the avc(h264) video codec and the aac audio codec. i set my resolution to 1024x600 since the NT only supports up to that much. Also set aspect ratio to 16:9 because most if not all my vids are widescreen.
hope this helps.

[Q] Is there a way to record video in a format other than 3gp?

Is there a way to record video in a codec other than 3gp? Or is there an app that anyone knows of that will allow you to record video in different formats like .avi .mp4
I was pleased to find that the camera for the froyo 2.2 build that eugene made shoots in the same HD aspect ratio as the 2.1 build but formats to MP4
also there are many encoding programs that work well. I am presently using Oxelon Media Converter to convert to AVI for editing in Premier and posting video on youtube in 720HD
Yeah I can convert them but I'd like to avoid having to add the extra step. I might have to check out that Rom if I no one else has any other solutions.

HD mkv playback - With Sample Links

* Update *
Youtube Video Samples below for comparison - some compression artifacts showing there, not from the sony tablet playback (it was flawless on either mode), most likely youtube recompression tools
Hi,
I bought one of these tablets just yesterday - 16GB version - and so far I'm extremely pleased with it! Typing is a breeze, image quality is superb, gaming is pretty decent even for 3D, I bought Riptide GP after upgrading Honeycomb to 3.2, but I'm having issues with HD mkv playback.
Basically, watching 720p or 480p even (anime mkv files) I get jerky video playback when the movie player is set to HW mode. The jerks are subtle and steady, but mostly noticeable especially on panning scenes. If I change the player settings to SW or Fast SW, playback is smooth but slightly less quality there (but totally fine though). I've tried several players other than the built-in video player and results are the same.
HD flash plays OK, so I don't think this is a hardware performance issue, probably some HW / codec compatibility issue....
Can anyone else confirm this? Horriblesubs releases (Naruto Shippuuden / Fairy Tail).
SD xvid releases play just fine, both HW and SW settings on the player.
Better .h264 codec support perhaps?
(apparently, not .h264!)
Oh, and quite pleased with the fact that video files can in fact be played directly from the SD card, without having to copy them to the internal memory storage!
I tried posting from the XDA free app in the Market, but somehow, it crashes everytime I try to post from it, so I'm using the android browser - already submitted a report.

I am having the same problem you described? Is this typical on all android tablets?
Looks like i'll need to convert unfortunately... I wonder if there is an app for that.
Unless it is a codec issue and there is an alternative codec or fix..
I'm curious, do you feel the quality between HW mode and either SW mode available to be that worse? I'm using SW for now on these particular files, I was thinking about converting the files original formats but SW still seems pretty good I think! I will try to snapshot the differences and post them here!
Hadn't noticed before, the tablet comes with 3 HD sample videos inside all play just fine, no jerks - seems more and more like a specific codec compatibility issue with tegra possibly, to me...
A software issue. I can play videos fine on my Jetstream and Ipad2 which play badly on the tablet S.
So it isn't an android issue.
For MKV playback try DicePlayer and install the Diceplayer plugin for tegra.
Try the trial version to see it meets your requirements (before buying).
----- snip -----
Diceplayer uses HW video decoder.
It use HW video decoder at various containers and audio codecs combination. ( H.264/AC-3/MKV, H.264/DTS/MKV , H.264/AAC/MOV )

Tried it, perfect playback with the plugin - bought it already, many thanks!
yeah DicePlayer indeed the best HW accelerated player in the market... support MKV, AC3 audio codec, subs... wooot

+1 I tried out MX player too but found that DicePlayer had smoother playback.
Working container / video / audio combo and easy conversion
I've tested several combinations of container / video / audio formats with several players. First of all, I didn't notice any significant differences in playback quality between the players I tried, but I might not have tried Dice player for all of the combos.
I did try MX Video Player, mVideoPlayer, MoboPlayer and BS Player Lite, with a 720p h264 encoded video track at about 3000 kbps. For all players, I found the SW decoding modes to insufferably slow and jerky - I assume a lower bitrate in the video track might fix that. Per hardware acceleration, the video always played fine (when it played at all, see format details below).
These combos did NOT work:
mkv/mp4 container, h264 encoded video, mp3 audio
mkv container, h264 encoded video, ac3 audio (plays the video hw accelerated, but doesn't play the sound at all)
mkv container, h264 encoded video, aac audio
The only combo that did work flawlessly was this:
mp4 container, h264 encoded video, aac audio
I now had the problem that my standard video encoding tool, handbrake, cannot transcode files without also recoding the video file - and why would I want to recode the video when usually it's a h264 encoded video that will play with the right container & audio? The easiest way to transcode such a file is to use ffmpeg - I did this under linux, but it should work the same for Windows:
Code:
ffmpeg -i INPUTFILE.mkv -vcodec copy -acodec libfaac -ab 160k -ar 48000 -async 48000 OUTPUTFILE.mp4
I couldn't figure out a way to easily transcode mkv files where the video track has a variable bitrate (VFR) - I had to recode those with handbrake. If anyone has a simpler method that doesn't involve avisynth / is available for linux, I'd be happy to hear it.
DicePlayer rocks. I tried various apps but only did DicePlayer works. Tested with a 1080 h.264 movie and the quality was STUNNING! Definitely worth the money
By the way, Honey does not support H.264 natively so most of the players out there won't work

[Q] What is the video codec used

Hi,
I wanted to play a video recorded by SGS2 in .mp4 format, but it looks like nothing out there can support it. It plays without any problems on the phone, but VLC, WMP and even WinAmp can't recognize the codec used. My question is - what is the video codec and is there anything that can play/convert it?
The *.MP4 file is a wrapper that binds both the video and audio + subtitles file.
Depending on the resolution, it can also be a *.3GP file.
*.MP4 usually uses H.264 video compression and AAC for audio format.
*.3GP stores video streams of H.263 or AVC/H.264 format, and AMR audio format.
In Windows 7, H.264 is supported without requiring to install any codecs.
3GP however is not supported in Windows 7.
If you are using Windows XP, you not only need the H.264 codec, you also need a MP4 splitter. As for 3GP, you need a codec for that as well.
Haali Media Splitter is useful for both MP4 and MKV files as a splitter.
FFDShow is a great all in one codec package for H.264, x.264, H.263.

Video codec: H264 MPEG4 (AVC)
Audio codec: MPEG AAC (mp4a)
I have no problem to play my mp4 files recorded by using my SGS2 with VLC.
Maybe you should check for an update of your VLC media player.

It is not necessary to convert - all on much easier) Install MX Player
Ffdshow and vlc should do it or check cccp codecs out..

[Q] Your preferred video file format, resolution for the NT

I would like to know what others are doing as far as encoding video to play on the Nook Tablet. The consensus seems to be the H264 encoding for video? What file format, m4v, mkv?? Does it make a difference? What about audio?
I have heard discussion about HW versus SW playback, what does this mean?
What resolution do you keep your videos in? How large should I expect the average full length movie to be?
usually 720 since they're smaller
2.5gb and mp4 or mkv
using mxvideo
sw btw for mkv and hw for mx vid
hd movies will be about 2-2.5gig
normal dvd's will be ~700meg-2gig(avatar) for h.264 format mp4/mkv

huh? Sorry, still don't get it.
Most videos play fine without converting for me. I just drop it in the tablet and use MX Player.
Also, .mkv is not a video format but a container.

playback h264 mp4 1080p

hi i want to ask,
i had problem with playing mp4 h264 files in 720p or 1080p,
the default player cant play the files and the other player (rock player, etc) can only using software encode and the result is lagging.
after i read some article, it said that the other phone that using tegra 2 is having the same problem.
is there any solution for this?
or maybe there's custom rom that could use some hardware encode for playing mp4 h264 HD files without lagging?
thanks and sry for my bad english.
