[Q] Poor Video Peformance - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

The video playback on my SGT 10.1 is really poor. MX video player stutters when the default hw decoding is set. On sw decoding it is fine but surely hw decoding should be better not worse.
Also, Flash Playback is awful. Really choppy playback.
Is this normal?

Depends on what type of video you are trying to play. This device cannot play High Profile H.264 videos smoothly at the moment (Most x264 videos people download now a days are High Profile).
I haven't come across any flash videos that wouldn't play smoothly but I haven't really tried any super resource intensive ones.

Please use the Q&A Forum for questions Thanks

Diceplayer supposedly able to play high profile MKV on Tegra2

I was reading on other websites and here when I tried to post this thread about a player called Diceplayer that can play high-profile mkv on Tegra2.
http://forum.xda-developers.com/showthread.php?t=1181938
I installed the trial but the app crashes for me before I can even select a file. Anyone else able to get the app to run? The thread above indicates it works on the Galaxy tab...
Hopefully someone else can get this app to work, the feedback seemed pretty impressive on the Galaxy forum.
EDIT: After reading the release notes it says that h.264 high profile still doesn't work on Atrix. Since other Tegra2 phones can do it, shouldn't the Atrix be able to as well? I wonder if it's just the software that they haven't optimized for the Atrix or if the Tegra2 in the Atrix is somehow different.
Sorry I fail at this, the info I was reading that said it didn't support atrix was from a previous version. Well I still can't get the trial to work on my phone and I don't want to pay $4 for something that doesn't work.
Statements like this give me hope:
I'm stunned speechless by Diceplayer. I had literally given up playing high profile MKV's on Tegra2 with the talk about hardware limitations. This thing cleaves through high profile mkv's like a katana through hot butter.

Diceplayer solve container problems. not Video decoding problems.
If your device can play H.264 high profile MP4, Diceplayer can play
H.264 High profile MKV.
but if not, diceplayer can't play it.
because diceplayer use same hw video decoder driver that is used by stock player.
You should retry playing your videos (in any player) after the 2.3.4 update, it seems to have fixed a lot of the h264 decoding issues for me
are you saying 2.3.4 plays high profile mkv files now?
I can play 480p MKV but 720p MKV stutters and is unwatchable

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

Cyanogen HW video decode

Hi there!
When I try to play 720p, 1080p and other resource-intensive videos (software mode for them very laggy) - there is only black screen in MX video player and BSPlayer.
I have tried cyan alpha 3, alpha 3.5, last xronified versions - still no luck.
As of what i have read - hw video decoder is broken when SoD fixed in kernel.
Logcat is here - pastebin . com / r23jkQzP
Maybe developers can look to this and fix this problem? Cyanogen is much better than WebOS, the only serious problem is that I need to reboot to WebOS to play HighDef videos. If I can help to fix it by any way - I'm ready to help.
I have insufficient posts to post directly in develoment forums, so doing this in general.
What type of video are you playing? Videos are playing pretty damn well for me using Mx Video Player. The videos that are hardware decoded in Mx Video Player are flawless and the software decoding does a pretty good job as well. Take for example this torture test video:
http://dl.dropbox.com/u/9502388/Planet.Earth.720p.Sample.mkv
High Class h.264 @ L5.1 720p mkv file with 6 channel AC-3 audio. Pretty much the toughest 720P file to play that I have seen. With Software decoding, MX Video Player flawlessly plays it up until the bird scene when the bitrate spikes up over 21000Kbps.
Not bad for an alpha release. . .

When running Android, are video players supposed to use hardware decoding?

When running Android, are video players supposed to use hardware decoding
when playing 720p/1080p MKV videos? (CM7, XRON, or that other one)
Thanks!
The CPU isn't quite powerful enough to play 720p video without the graphics acceleration from what I'm seeing.

[POLL/Discussion]How has playback of 1080p h.264 10bit video been for you?

On a forum I'm a member off, a discussion started about many phones today that may struggle with this type of video content including importantly, the Z2.
Now I watch a fair bit of anime on my phone and a lot of it is encoded in this profile but I often watch 720p encodes and these are prefect on the Z2 as for 1080p videos I've only watched a couple but these were very smooth as well but I just want to see what other people's results maybe.
Just to be clear I am referring to 10bit encodes, if they were 8bit then it would be hardware decoded. The profile for 10bit encodes is also known as Hi10P.
MOD EDIT
I have changed the title of the thread as it seems you are trying to start a discussion. If you did mean to ask a question then Q&A is the correct place for it.
 @gregbradley
For 720p it's very smooth, no problem at all. :good:
For 1080p it may lag/stutter a bit in some scenes (usually the fast action scenes). But it's fairly smooth most of the time and very watchable.
I've tried a 720p h.265 video too, and it's smooth ^^;
I'm using MX Player.
I would have to check which one are 10-bit. But so far no problems using BS player and a Synology NAS. Will check when I get home.
I have a z2 and yes i agree with you ravdo 1080p movies some action scenes lag and stuttering i dont know why becasue samsung s3 s4 s5 was perfect on 1080p videos no lag and stutter i dont know why z2 does and also z2 plays 4k videos so interesting anyone can explain why or how solve this problem?
