Hey Everyone
Hope this is the right section, cuz i thought its not development or anything just a question if someone can test this. Can someone who has overclocked their device, test if Rockplayer can play mkv 720p? Does it work smoothly or still lagging?
Regards
Baddar
Different people might try different 720p files, encoded with different options and bitrate.
Maybe it would be best if you post a link to a freely available 720p trailer mkv, it would then make sense to test different players and different clock speeds with the same file.
EDIT: I will be trying this on G.I. Joe 720p H.264 MKV AAC Stereo 53MB file.
Found on: http://www.divx.com/en/electronics/solutions/high-definition/divx-plus-hd/video
So when overclocked to 1.3GHz RockPlayer shows about 10 fps. VPlayer seem to be faster in decoding that file, but also not perfect.
EDIT: All current players probably use the same FFMpeg libraries so are more or less the same performance.
I think we have to wait until CorePlayer for Android is released, it is known for it's own decoder and ability to use hardware for decodin. On my ePad Atom 1.6GHz slate, CoreAVC codec allows me to play H.264 720p videos flawlessly (at CPU being used at 90%). It's the only codec that allows me to watch H.264 720p videos on that device.
I have tested it and found same problem at 1.4ghz. Hardware decoding wont play the file and software is laggy. So wait for coreplayer?
How's MP4 video playback with recent versions of CM7? I'm running Phiremod 6.2, which is based on CM7.02 and it's decidedly sub par. Not nearly as good as stock 1.1.0
There are many topics about this matter.
After 5.x Phiremod versions, having some good player (like Vplayer) someone could enjoy even matroska videos at 720p.
Mp4 play also fine as avi

Thanks. I'll give that a try. I've tried both the included viewer and MoboPlayer and, while MP4 movies play OK, framerate is not up to the standards of stock 1.1.
Well, I tried Vplayer Pro and was generally disappointed. Seems that nothing plays as smoothly and transparently as stock 1.1.0. It's unfortunate, even the official Barnes & Noble OS upgrade doesn't play video as smoothly as the earlier OS releases.
I'm sure hoping we get an update at some point that brings back true, cinema quality playback.
The next CM7 nightly should have decidedly better video playback.

Oooh, can't wait! Getting video back to something like 1.1 stock would make my day. I converted over 100 of my DVDs back when I was running Autonootered 1.1, and playback was flawless then. If Barnes & Noble could also improve the speed of the Nook App for Android then I'd have a device that could easily last me a couple of years before I get the itch to upgrade.
BTW: the work you guys do is amazing.
Slightly off topic, but the Netflix app, on the other hand, has beautiful video quality.
One of my favourite things about the Tab 10.1 is video format support. My #1 use for the device is watching videos during my morning/afternoon commutes. I download some videos the night before, and drop them onto the SD card in the AM. The Tab was able to play all of the formats I threw at it in 720p no problem, in the stock video player.
The first thing I noticed when I turned on my TouchWiz-updated tablet this morning is that none of the videos on it work. They show up as thumbnails in the gallery and video player, but cannot be played. In Moboplayer, the 720p files struggle because it's now relying on software decoding.
Is anyone having different experiences, or have a work around? I really hope this is not an intended change, or I'm probably going to return it. Too bad as I otherwise really like the update!
The update broke 720p high profile support. 720p baseline still works fine and the difference in image quality is negligible imo.
I hope they fix it in the near future, but as it stands now you either take the improved browser in this TW update, or go back to stock 3.1 or one of the older TW leaks and get 720p high profile support.
That sucks! I am assuming it is a bug and they will fix it.
I apologize for the upcoming noobish question as I'm not particularly familiar with codec's, and don't know the different between baseline and high profiles. I'm assuming I can convert one to the other in one step with handbrake? And would the difference in size be substantial?

Yep use handbrake and the baseline profile attached to this post: http://forum.xda-developers.com/showthread.php?t=1060825
Just queue up your files and walk away. I think the files might end up slightly larger but I'm not 100% sure, either way it isn't a big difference.
I'm also assuming it's a bug as high profile playback was a feature that was added in HC 3.1
DICE player is still able to play my 720p high profile (in a mkv container) smoothly.

Interesting... I'll grab it and try when I get home. Do you know if it is designed for the Tegra 2 and using the GPU to decode the video (I'm assuming it is otherwise it should be stuttering)?

It states it uses hw acceleration on Tegra2 devices.
all the mp4 vids i had are still playing nicely on mobo player
Can anyone comment on DivX/AVI support?
I picked up my GT10.1 today, and since it supports DivX out of the box, gave some a try. I was disappointed that the picture broke up and pixelated repeatedly on every AVI I tried. So, I installed Mobo Player and tried it in software mode, but got exactly the same results (which surprised me somewhat).
I also have an Asus Transformer, and those AVIs play flawlessly on the TF using Mobo Player in software mode (since Asus didn't add hardware support for DivX).
I'm wondering if this is related somehow to this issue, since my GT10.1 came with Touchwiz.

Dave
720p High Profile H264 is indeed broken. Verified in Mobo Player and System Media Player.
How do I know they are high profile? I made them, and because I only encode in high profile via handbrake.
Bummer because the Tegra2 handles 720p High Profile H264 wonderfully prior to this update.
I have 4 video players loaded because the built in video player couldn't play all of the videos that I have loaded. Ironically I have the exact opposite experience of the OP, it now plays all the formats I have loaded.

Can you tell us which players you use? Do you need all of them? Does one work better (produce better quality) than the others? Thanks.

This is extremely disappointing news because one of the things I love about the SGT is the quality of its video playback. My friend has a Xoom and he was blown away when I showed him some hi-def videos I downloaded.
I have a lot of high-def videos I downloaded straight from Vimeo, and they play flawlessly on my SGT without any conversions whatsoever. The thought of having to use Handbrake -- or anything else -- to convert every video I own is not very appealing to me. I hope Samsung fixes this problem.

I have mVideoPlayer, which I like the best. I also have ES Video Player which comes with the ES File Explorer. And, I also have VPlayer.
VPlayer will play anything I throw at it. I've never had it not play a video. I only downloaded it because it's required by Remote Potato. Remote Potato lets me play Recorded TV from my Windows Media Center cable card tuner.
To be honest, this is sort of souring the update for me. I'll be testing when I get home to confirm there is no problem playing back lower resolution files. Still, I like to keep a few high-def movies on my Tab and don't want to convert them all. I hope this is a very temporary problem, not something that gets fixed for the 3.2 build.
I don't know if this is related, but when I was trying out the new Kies app on my PC with my tab connected over Wifi, it (Kies on the PC) offered to download new codecs when I first tried to transfer a video over to the Tab. My PC shouldn't have needed new codecs since all the video play on my PC.

x2, just tried it out and it worked fine with my high profile 720p videos in mkv and m4v.

Just to add, the TW update apparently fixed ac3 audio playback.
my video players including the stock player play "high profile" m4v and mkv's perfectly
what a dumb thing to do Samsung..

Well, the stockplayer can't play this pixar short movie. At least, it doesn't on my Tab... Dice Player plays it smoothly.

Xoom USA Wi-Fi version.
Installed rooted stock 3.2.1.
Kernel Rogue 1.4.3 Rana.
My problem is I got it MAINLY for watching videos, and I can't seem to get it to play 720p videos smoothly.
Tried playing 720p directly, tried re-encoding from 1080p and 720p using Xilisoft Video Converter (chose Motorola Xoom H.264 profile), tried re-encoding from 1080p and 720p using Handbrake and recommended user-presets.xml containing Xoom video settings etc.
It does play 1280x720p with hardware decoding, but, depending on the video, it stutters for an instant now and then.
Comparing to playing a file on the PC, or laptop, or DVD player, or blu-ray player, or my WD HD Live media player, it's NOT as smooth, i.e. I do notice those "stops" and they drive me nuts.
Should I wait for ICS or change some settings or simply sell the tablet?
Thanks.
This has been addressed a few times already but I will try to give an answer. Yes the Xoom can play 720p videos. The most important factors being what format and which player you use. I personally use Dice player which plays all my 720p videos with no conversion needed however if you must convert, DVD Catalyst does a stellar job. I have played 720p movies files in .mkv and .avi format on Dice player ranging in size from 2GB to 4GB with no issue. The only setting change I made in Dice was to have the stock player handle .mp4. I have used the stock player to play 720p .mp4 files with no issue. Use the search function to find the threads explaining how others are doing it.
Thanks, I'll try again.
Tried RockPlayer, MoboPlayer, VitalPlayer so far - same
And I did use the setting for 720p recommended by others.

The stuttering was still there...
Try Dice Player. What video size/format are you trying to play?
1280x720 X.264
I'll try the Dice Player, thanks.

You could also experiment with the ICS alpha build--it's very stable on nightly version 17--and plays videos very well. Read the Team Eos nightly thread in development for more information.
Yes, I thought I wasn't going to sell until at least seeing how it worked on the final ICS for Xoom...not sure I'm willing to play around with the nightlies though, but thanks for pointing that out
BSPlayer, the older version (check the thread in the XOOM App section for the APKs), works great too. Especially since it doesn't try to sell you the program every few seconds while watching videos.
For best results with any player, make sure to use baseline profile when x264 encoding. No B-Frames or weighted P-frames.
What's really funny I encoded The Guard in 1080p to 720p, due to wider screen the end result (keeping the ratio) is like 1280 by 514 or so.
So I used these settings:
http://www.notionaddicts.com/forums/showthread.php/4291-Tegra-2-Friendly-Handbrake-Settings
Also attached a Word doc in case the URL goes bad
So B-frames are there, I repeated the profile one for one.
Guess what? perfectly smooth playing, using MX Video Player 1.5a.
No trial, free, just ad based, but I have Adfree for Android running, so I don't see any ads whatsoever.
I still get lagging playing some 720p MKV's in HC. Just wondering if the ICS hardware acceleration would improve on this and make it work smoother?
I have tried all players such as MOBO, MX, RockPlayer and Dice. Sometimes when I choose HW accelration it crashes the tablet.

Remember this is a leaked Beta rom. Thou most things do work there will still be alot of tweaking done by acer before there final push.Also many apps are not totally updated to support ICS.
So we would hope hardware acceleration will improve but to say YES would be guessing.
hope this helps .
I've just tried it, but i have to say it's not smooth at all. Maybe later
(MX player, Lightspeed_4 ROM)

You should try convert mkv to mp4 and use MX for play.

I rather not try to convert since all my movies for the home is on a server. I try to stream to the Iconia but it lags. I have tried it on SDcard and it still lags. These are 720p rips of BR usually 4-6gb in size.
HW Acceleration works, even on the leak. The problem is that it doesn't support Vorbis/Theora, which are mostly used in mkv files... So these videos are never going to play really smoothly, they might work or not depending on system load and whatnot.
As to some apps not being properly ported to ICS: True, but for MX video player it is officially supported and has been for a while.

I had the same issues before. A500 can't play smoothly rips of BR because it is not fast enough to process. Converting video to mp4 or wmv with lower rip-level is the only solution. Sometime the converted larger than original file but... it's work.
I use DVD catalyst 4 to convert my DVDs to MP4 for my Iconia. There are presets for the Iconia. I personally like the HQXT preset. It gives good performance for both action and slow paced movies. My movie file size is normally 1.3 gig.
Its not only mkv that has problem with ICS, its every HD video 720p and above. Even streaming videos like NBA is lagging and ugly to watch. But I know this will fixed soon because v96 video playback is really smooth.
Try streaming again using a program like Emit or Qloud. Both will re-encode the files to a specified bitrate while streaming and you can leave them on your server. I haven't tried it over 3G/4G but it works great over wifi.
yes indeed, but you need a good CPU on your computer for that.
not my case..
and frankly, seeing some low-priced chines tab running 720p without any problem makes me a bit crazy..
tegra2 was a real success.. from sellers points
but at a technical POV, not sure it's soo great
