I know this was mentioned before in some sense but want to get some opinions on what to do to get the best video playback.
Right now I am on Honeycomb Illuminate 1.6 and overclocked to 1.5ghz
This seems to work decent with software decode of the video. At the very least better then stock with hardware decode.
But for some reason the subtitles seems to lag out a like 1 second. And I don't know why...it could be that the video is still lagging by a few frames and I just don't notice it or maybe it loads video first, then subtitles so they don't sync correctly by a few microseconds I am not sure...
So I am at a standstill..should I go back to a Froyo based rom with hardware decode but 1 core and try overclocking that 1.5ghz. Or stick with my honeycomb with software decode and 2 cores clocked at 1.5ghz...
As for media players I tried:
Moboplayer (is what I am using now, subs lag a bit)
Vital Player (crashes on software decode in honeycomb, havent tried on froyo)
mvideoplayer (subtitles too small, and didnt work in honeycomb)
rockplayer (also subs lag a bit)
yxplayer (unusable)
Also these players cant seem to display multiple lines of overlapping subtitles for some reason(like top and bottom)..anyone know if a player can do that?
Anyone have any suggestions? (I don't want to trans-code the videos)
So..no one has an answer to this?
first off. people here do a hit a run. posting a rom and not supporting
second
honeycomb doesnt have full hw accelaration. i compared using froyo and hc. hc just lags horribly bad. both sofware and hw.
i think its partial hw accelaration. but still has time rendering stuff.
and dont know your subtitles solution
cheers

I have gotten HD playback on my G tablet Honeycomb using Flashback 7.1 overclocked to 1.4 ghz
I got it working by downloading MX video player and its codecs to play videos
I downloaded a bunch of 720p movie trailers, the ones I tried for the youtube video (I'll upload tomorrow, phone is dead) were Avatar (2009) and The Darkest Hour (2011).
Now I know stock g tablet 2.2 can play 1080p hd videos, but the fact is, even if you can play the 1080p movie on the g tablet, that doesn't mean it will have 1080x1920 pixels on the g tablet, it will downscale the 1080p video into the maximum resolution on the g tablet that is 1024x600. That means that it also scales 720p videos. So in reality, its not even worth trying to play 1080p videos on the g tablet.
But as far as playing the video, its acceptable, there is a little choppiness that you can see here and there.
My testing from last Sunday, as well as Edirector's tests in teh Illuminate thread did show that it was possible to play HD video downloaded from Youtube usign software decoding. I tested with Flashback and could play everything he was playing, including the Bluray ruality rips he kept talking about.
What I was able to show was that hardware decoding was still not possible on HC roms, meaning that hardware acceleration was not working, and can not work unless drivers are obtained.
I went back to Calk/Clem Froyo rom and am able to play videos using hardware decoding. the quality is a "bit' better, but nothing to write home about. The difference come when viewing on the TV via the dock. Hardware decoding does improve the picture.
Any rom, with the right video applications can view videos using software decoding. Oveclocking isn't even necessarily needed to do so.
This was why at the conclusion of my testing, I questioned the need for hardware acceleration at all. If the HC and GB roms can watch HD video using software decoding, and the difference with the hardware decoding on Froyo roms is minimal, then why is hardware acceleration the deciding factor when going to an HC rom? For me, personally, it's because I use the dock. Hell, my famly just watched 3 movies today on the TV through the dock...
I just need to find a video player that supports AC3 audio in hardwae decoding mode.
Battery Life
Two main reasons to choose Froyo over GB or HC for the hardware acceleration are that with the HDMI cable and dock if the video isn't hardware accelerated, it looks crappy on the TV. Also, and more importantly, is BATTERY LIFE! Hardware accelerated decoding uses MUCH less battery. So if you were on an intercontinental flight like I was last month, you can hardware decode 4 movies and still have about 35% battery, where as you might be able to squeeze out 2.5 movies using software decoding. To each there own...but I bought the Gtab to watch videos mostly, so I want to use the hardware optimized for it.

Heck yes! That's the one thing that burns me up...how the Tegra 2 doesn't decode AC3. We need a video player that will hardware decode the video stream, but software decode the audio. Shouldn't be to hard to do right?
Hi, I know there has been some discussion about this already but I dont think this has been properly resolved.
I am fully aware of the tegra 2 video decoding limitations so lets not get into a discussion about that.
Basically, on the website Samsung suggest this can play 1080p video and there are various videos floating about suggesting it can plan youtube videos in 1080p format.
Now, here's the rub....
If you play a video in none desktop mode it plays great but this isnt in 1080p format, this is pretty obvious if you pump it out the HDMI. If you attempt to play it straight out of the browser, stock or Dolphin it stutters in 1080p and is just about watch-able in 720p.
So, I am wondering exactly what 1080p video sammy are actually referencing to?
On a side note however I have found that DICE and MXplayer do a really good job or playing main and high profile MKV's to the point where 720p high profiles are watchable at stock cpu 1 gig and smooth at 1.6 gig overclock (neither is hardware decoding, all done by CPU).
wow 60 views and no replies... ghost town in here...
Samsung simply repeats what Nvidia states which is the tegra 2 can only play 1080p video encoded in Baseline profile. The problem is nobody uses Baseline profile as its obsolete and has poor compression.
Youtube certainly does not use Baseline profile when it re-codes videos uploaded to its servers and that is problem....
Yes the video decoder in the tegra 2 sucks balls.
I dont think that is right, flash 3.2 is supposed to have tegra 2 hardware acceleration and should be able to play 1080p youtube stuff through a browser.
http://www.samsung.com/global/microsite/galaxytab/10.1/spec.html
See here, it still states full 1080p video playback, if it cannot play youtube 1080p then you have to wonder what it is refferring to exactly?

Just because it has hardware acceleration of a codec does not mean it can play all 1080p video as explained with h.264. If the video is encoded with too high of a bitrate the tegra 2 hardware accelerator chokes, and it does not take much to choke it....
Unfortunately advertisement is inherently deceptive as the case with the link you provided.
Does anyone have any more info regarding this? I really thought that with the 3.2 Honeycomb update they would optimize the Tegra 2 GPU more, but it still cant play any stream or youtube video at 1080p.
Hey, I just threw this up over at RootzWiki as well, but I think I may have found a working video player for CM7 Alpha 3.
All credit for the fix goes to the user that posted the modified apk, meaning: In NO WAY do I personally take any credit for this video fix for CM7 Alpha 3.
I luckily just stumbled upon it while trying to find a working player.
The apk seems to be a modified version of MX Video Player. Download the apk file here: Alpha 3 Video Fix
The user that originally posted the file is looking for feedback so try and give him some if it works for you too.
Hope this helps
what exactly is the problem with video playback? i have the non-modified MX Video Player installed and playing mp4 running hardware decoder. no problem. xvid/avi plays fine as well
I use moboplayer and it seems to work just fine also
maybe those having problems are trying to play 720p or greater on the tablet. in that case the fix isnt for me. takes too long to transfer
Ive been using moboplayer since alpha 2.1. Never had issues.
Sent from my PG86100 using XDA App
MKV files (at least the 720p ones anyway) werent supported with hardware rendering previously in mxplayer on my touchpad/android alpha 3, will be interesting if this is what the newer version fixes.
Edit: Still doesnt support hardware rendering for 720p MKV but seems to run quite ok in software mode. Hardware rendering would be a bit smoother though no doubt, particulary for upscaling lower video res.
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.
I used the latest VEGAn-ge-7.1.0 for the 1.2 bootloader on my gTab with CWM the other day. First time ever flashing a rom and everything went great! The problem I'm having is that the built-in video player in VEGAn will no longer play my mpeg4 movies/TV shows. With the stock ROM on the gTab I never had any problems with the built-in videoplayer OR mVideoplayer. They both worked just fine. Once I flashed VEGAn my movies wont work.
I can only assume it has something to do with hardware acceleration.?.?.?.? I have over 5tb worth of movies and tv shows already ripped from my collection, I will NOT re-encode anything at this point!
99% of what I use my gTablet for is watching movies while I'm at work(I'm on call with lots of down time) I would love to use a better ROM then the crappy TnT stuff Viewsonic shipped this thing with. But I cant NOT be able to play my mpeg4 movie files.
Is there a good ROM that will let my mpeg4's work like the stock ROM does? I dont care about any fancy features or anything in the ROM, I only watch movies on this thing and play the occasional game. But if I had a better ROM I'm sure I'd use this thing for more then what I do now.
My mpeg4 encode settings used in DVDFab are as follows:
848x480 resolution
3000kbps fixed bitrate(less then this movies can get pixelated)
128bit DolbyPrologic2 audio
FastEncoding 1 pass
These are the best settings for mpeg4's that I have found while testing out various settings when I bought the gTab. From the looks of the settings could it be that I need HW accel video playback instead of SW?
Any of the Froyo based roms such as Beastly-Clemsyn (my favorite, very fast and stable), Frankentab, BC, etc all have working hardware acceleration, as does the new ICS beta. You are probably right about the hardware accel. being the problem, this is the same reason I always end up back on a Froyo rom. I have encoded a lot of video that I stream from my main PC, and there is almost always skips, freezes or audio sync problems on roms w/o hardware acceleration.
You can also try on your current rom, MXPlayer and Mobo Player have versions that are optimized for ARM v7 (Gtablet). In the players settings, change from hardware to software video and audio decoding. Most of my videos play alright with MXPlayer on software decoding using CM7, which doesn't have hardware acceleration.
Last, you could try Qloud Media, if you have a pretty fast PC. Qloud will re-encode and stream your video from the PC, optimized for the target device. It works very well on every device I have tried it on, and can even work beyond your network, but it consumes my entire 4 CPU cores in bursts of a few seconds while it is re-encoding, so no intense PC usage while it is running.
Thank you! I'll try and stick with the Froyo based ROM's. I've DL'd quite a few different ROM's but I have yet to install any of them other then the latest VEGAn one.
