I'm not sure that how many people at here know this fact.
Tegra 2's H.264 decoding is waaaay worse than Hummingbird(Galaxy S)
It cannot run any HD H.264 video HP.
Source?
Tegra2 can decode 720p at AVC HP and 1080p at AVC MP with reasonable/usually bitrates at 30p.
€dit: Just seen that u have the korean model, right? AFAIK the LG-Player isn't supporting the mkv-container,
allthough Tegra 2 would be up for the task (at 720p30 HP) as mentioned earlyer.

I think with VLC or RockPlayer you can probably see a difference
How does x264 perform?
I think its the same issue as Adam had with the video/audio desync. Its not a hardware limitation.
I don't get it. I've tried various videos and none of them work properly. However, the demo video files that were on the device (1080p) run perfectly. No frame-skipping at all.
Is there something I'm missing?
I was kind of baffled by this too.
Brilliant playback on the included 1080p files.
So i thought yay lets grab some 1080p trailers from youtube with tubemate.
But alass. not very smooth! Think its indeed the profile that does the trick. or in this case, doesnt.
Next thought. Ok rockplayer will help me out here!.
But i wasnt too impressed with rock on my galaxy s either!.
Loaded rock. but also very crappy. Which is when u think of it, pretty logical.
Why? No hardware support! Rock doesnt even remotely know what a tegra2 soc is. and in fact, NONE of all the video apps do.
So in stead of funky tegra2 hardware decoding, you get software playback.
Ive heard some rumors about nvidia developing an android video player for tegra but i dont know if this is true or not at all.
so unless someone makes a proper video playback app (which in my opinion is way over due already! no offence but theyre all crap if u ask me!) which supports hardware playback AND tegra2 soc, it wont improve very much.
My 2 cents
Ok some more info, apperently Tegra2 isnt very great with high profile encoded. baseline and main profiles should work. more testing to do. Also everything below 1080p high profile should kind of play properly. My eyes are on VLC for android and fingers crossed for them to bring tegra2 suppot and their own great codec sets
Check the Motorola Atrix forum, on XDA (sorry cant link from mobile app), they have basically given up on playing hd h264 files on tegra 2. Such a shame.

Yes indeed. It sucks ass. I have the same unit but then from T-Mobile Netherlands. Video included works like a charm (ofcourse) but own added videos look like they are in slowmotion. 720p, 1080p doesn't mattter same issue.
Extra added flaw? When your record video in Full HD it does not play back on Full HD TV's or BD players. I checked why and found that it actually records in 1920x1088p!!!! Yes 1088P people.
FOTA updates are also not working for the T-Mobile branded unit. Comes back with validation error.
Tegra 2 limitation
Some search on the internet revealed that Tegra 2 supports fully h.264 main profile, but for high profile, it is only 720p 6MB/s, which is then not suitable for a BD. Anyway, I don't have the intention to fill in my 32 GB of storage with just one movie...
Recording in 1088p instead of 1080p is a bit more annoying, you think there could be a solution for that?

Yeah MVK-files can be played with other videoplayers on Market but I've read in reviews that it's awfully "laggy". Saw a video where they tried to play mvk in RockPlayer, i think it was, and damn... looked like 1fps!
I tried to play a mkv file yesterday with the build-in player which crashed my phone.
I installed qqplayer and am pretty satisfied with the result.

What kind of mkv did you try? 1080p?
I keep saying its a software issue causing all these troubles, i have a Adam and since the latest update i saw a improvement on the video playback.
Once we get proper support for mkv it will be awsome

Do you have a video of the adam playing back mkv?
You can search in the thread @ my sig for " Notion Ink Adam Qi Vs Motorola Xoom by Inspiron41 "
I can add that any file that i have MKV to be played has to have the extension changed to AVI and only QQPlayer can run them, if the sound quality is high more than 2 channels the fps rate will be low this happens with either 720p or 1080p. But if i try to run a MP4 file with 1080p it runs very smooth with audio and video sync, so for me its a issue with decoding of MKV.
Oh and the Adam is running froyo no multiprocessor support neither the video apps do.
LG's Optimus Q(LU-2300, only for south korea) has same snapdragon 1st gen 1ghz cpu. But it can play h.264 high profile 4.1
Both devices are using snapdragon.
It is possible that play high 4.1 videos on nexus one?

LG probably has licensed codecs and a modified kernel to take advantage of said proprietary codecs. I did a quick check online and couldn't find any mention of h.264 playback. The only mention of 720p is for the camera.
Quote from Wikipedia:
"There is built in hardware decoding for H.263, H.264 and MPEG-4 video"
http://en.wikipedia.org/wiki/Nexus_One
It can also be seen in device specs.
So yes, most chances that the will be some video player that will play h.264.
hi,i used modaco's desire port for nexus one rom,and it surprised me with playing 720p in realtime,and also great camcroding on720p,i tried to play some youtube's 720p videos(downloaded FLV file from youtube)and it played it really really great,smooth,realtime!
which one i should use for our galaxy note ?

Hi all,
I started out with the stock 3.2 ROM, I quickly switched to Overcom ROM 3.2. I was happy with it for about 8 months.
Then I decided to go to ICS and later JB.
Every ROM I've used so far has the problem that HD movies on YouTube don't play very well. Every few second it will stop for a fraction of a second, it's really annoying. The audio is never affected though. It happends when the video is small and when it's full-screen. The moment I switch from HD to HQ the problem is gone.
I tried about anything, even overclocking up to 1.5 GHz. doesn't change a thing. I'm pretty sure it's not the capabilities of the tablet, if I play 720p trailers on the IMDb app it plays all video's perfectly. Also, when I use the 3.2 Overcome ROM backup the problem is gone as well! I can't go back to 3.2! I love ICS and JB too much!
Are other people having this problem? Or does anyone knows the solution?
I was wondering if this has something to do with the kernel, so far I used the A1 kernel and currently I'm on 3.1.10 Cyanogenmod+ kernel and CyanogenMod 10, with Android 4.1.2
Again, from the Asus Transformer Forum about the Tegra 2 and HD content -.- :
"The Tegra2 chipset are designed as a mobile sollution chipset - to support web 2 standards. The highest encoding profile used here (Youtube 1080p) are 1080p baseline and this the Tegra2 chipset will both record and play with no troubles. As well as 720p baseline and main profile - but only upto L3.1 with some limitations. It doesnt matter which container is used (mkv, mp4, m4v, avi etc) and it doesnt matter if resolution are 1080p - its only a matter of the encoding profile used to encode the supported video format H264
Tegra2 will NEVER be able to decode High profile L4.1 encodes - it's not a software issue, neither in terms of Honeycomb or Nvidia libs, its simply a limitation of the abilities of the hardwaredecoder in the Tegra2 chipset and this will never change. It is also not a limitation in the Transformer specifically, but a limitation in ALL Tegra2 based tablets and mobilephones.
This is the same reason why some mediaplayers like the Boxee Box that was originally intended to use the Tegra2 moved on to an Intel chipset before launch.
In short the Tegra2 chipset will support playback of videos encoded in 1080p or 720p resolution, using the H264 video codec and AAC audio codec - as long as the video are encoded after the baseline profile standard
It will not now or ever - play 1080p/720p encodes encoded after the high profile standard."
Youtube HD is not encoded as it has to be for Tegra2 chipsets to play without stutters..
Next time, please serach the forum, there has been several threads about hd content.

While I agree the issue was mentioned before (it's even on my faq ICS), none of your reply addresses the observation, made by several folks on this board, that certain (youtube) HD videos played fine in HD, but stutter in ICS. Or did I miss something?
I read a suggestion somewhere, that video would stutter less in ICS (correction: jelly bean) if developer USB debugging mode is off, but I didn't see a difference...

Well, i have to admit that youtube hd videos did not play fluently on HC for me. Therefore I think that the android version or kernel doesnt matter for decoding. I might be wrong though..
With that being said, i think that there is no solution to get it fixed.
Btw that USB debugging thing does not work for me as well

Thanks Ncyde47 for that insight..
I had issues with prefetch not working with latest youtube version and had installed an old apk which was working good.
I am on 4.2.1 and tried to play some 720p and 1080p MKV with BSPlayer and DicePlayer which works great on my EvoLte phone. I just got this tablet yesterday and tried playing these videos and get stuttering like crazy. I also have HP touchpad with android and it plays smoothly.
I am doing it wirelessly via the LAN and Samba on these players on both the Nexus 7 and EvoLTE. The nexus can't play smoothly. Is it my wireless signal is better with EvoLte(5ghz band) or is it Tegra 3 can't handle MKV's. I have a Tegra 2 and it can't handle MKV's also.

Try using MX Player.

JB 4.2.2 with MX Player Pro (+ codecs) no problems at all.

BSplayer
i have never had any issues with BSplayer stuttering.i use it on my nexus 7 as well as my galaxy tab 2 and have no issues.another good player is Archos Video player.just install the codecs with it.its nice.BSplayer though...best imo.
I recommend XBMC. Go to mirrors.xbmc.org, go to test-build and get the hardware accelerated build (feb 19), it can handle more codecs than MX Player.

I will try XBMC with HW accel. I tried the regular XBMC and it was the worse.
The people who have it working smoothly are you doing it wirelessly? I am thinking that is the problem.
I think SMB might have made it bad because streaming with the N card in the Nexus 7 is slow. I think it's one stream N which is barely above G speeds. My EvoLte and Touchpad which have both 2.4 and 5ghz bands seem to play it smooth.
I tried MXPlayer using ES file explorer to find the file. It was better than BSPlayer and DicePlayer in playing.
I will try to put the file directly onto the memory but I only have 8gb which kind of limits what I can put.
Use ffmpeg plugin for mxplayer/diceplayer/archos if you are not. Also makes sure to use HW on dice and HW+ on MX.

With XBMC hardware accel, both offline and streaming 1080p videos play smoothly. If you are paying the video from a flash drive connected through USB OTG it could be the problem due to the read speed.
You can also try VPlayer, it also have DLNA plug-in.
Archos videoplayer is the best videoplayer by far currently, build in SMB support, automatic covers, subtitles, etc, smooth hardware playback of 720p/1080p mkv on just about any device

You'd better transfer you MKV to .mp4 before you put it to your Tegra 3/2. I am using Pavtube Video Converter to do the conversion and I think the effect is very good.It can support to transfer any video format to the suitable format for your devices.Have a try of this and hope it can help you as well.
