[A] Choppy Video Playback - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

First thread and post! Hello everyone!
I have not found the solution to this problem on any thread on any forum yet, but here it is (with some back story)!
I had just got a Tab 10.1 P7510 (wifi only retail) running Honeycomb 3.2. To my dismay, video playback was choppy no matter what format I wanted to play, no matter what player I tried (MX, Dice, Mobo or whatever it is, native Video, etc).
I read here and/or elsewhere that Touchwiz was the culprit.
I read here and/or elsewhere that videos not encoded by a strict set of rules was the cuplrit.
Poppycock! I can play all the same videos on my Casio Commando in MX and on my kids' Archos 101 Gen8 tablets without a hitch using the stock video player. FLV, H.264 MP4, Xvid/Divx AVI, MP3, AAC, AC3. Doesn't matter! However, any video format I played on my SGT was choppy.
I was thoroughly frustrated by this point, as you can imagine.
To get around Touchwiz I flashed CleanROM Rewind 1.0 (HC 3.1). Problem solved! Except now when my Tab would go to sleep, waking it up presented scrambled video output, requiring a cold boot. I flashed CleanROM 1.2 (HC 3.2) and so, back to choppy video.
THE PROBLEM AND SOLUTION
The problem, as I serendipitously discovered it, was HARDWARE rendering! All I had to do was turn on software rendering in MX and suddenly my SD videos are playing smoothly, regardless of how they were encoded.
I didn't bother with the other video players because they did the same thing as MX, so I safely assume that those players have the option to switch between HW and SW rendering.
I hope this helps some folks out there!
As an aside, thanks to all of you in the Android community for helping me solve most of my other problems!
EDIT: I only had to enable software rendering, not turn off hardware rendering (I don't think you can disable HW rendering). In the case of MX Video Player, it appears that it will use HW or SW as it sees fit.

[Q] RUNNING UnNamed Rom v1.3.0 on i777-Video playback Problem

I'm currently running my phone SGH i777 on Unnamed rom v1.3.0, i'm experiencing some problems on video playback on my current rom. The video stutters while playing less than even a second but happens quiet constantly on the phone. I wanted to know is the problem with the hardware of the phone or does the problem exist on this rom.?

No problems here - but it depends on the video. Video that uses certain features that are part of H.264 High Profile can do weird things.
I am on UnNamed 1.3.1 and hadn't tried video playback since I installed so I pulled up Mobo player and tried some movies on my SD card. Movies with dolby digital and two channel AAC would sometimes close as soon as they started although they would play after I tried a few times. Video without dolby digital seemed to play first time. I looked at the Mobo options and turned on "soft decoding". I haven't got a close since then. Video playback is very smooth (32GB class 10 uSD card). My videos were encoded in Handbrake as H.264 using the AppleTV2 setting. I only use AAC for movies that don't have much of a soundtrack.
These were videos .mp4 that i downloaded using tubemate and played them on my phone..In software decoding mode the're working fine in HW dec mode stutter while playing, so does that mean that the default video player on this rom is unable to play back these videos with the support of the hardware..?

[Q] Video playback issues

Maybe its just me, but I've been having some odd issues with video playback on my new Tablet S.
Basically, anything that the Tablet natively supports works just fine. But anything that requires using a Software Decoder (like MX Video Player, or QQPlayer etc) goes weird. The audio and the video will become unsynced as the video playback framerate is much lower than the original file while the sound plays at the normal speed, sending it far ahead of the displayed video.
Does anyone have any suggestions on better ways to play non-supported video files?
Dice player has worked for me without any problems. I've heard of problems with sync on MX but who knows, give Dice a try and see if it helps...

I'm using BS Player lite, had no problems with avi or mkv.

[Q] Video Player. Which one?

Hey guys,
Loving my Prime but I'm finding the video playback hit and miss to be honest.
I'm finding them all very buggy and most of them kick me out of the video randomly even without anything else running.
All of the below run perfectly on my friends Galaxy SII so it may be ICS?
I want to play back XVIDs and MKVs with subtitle support.
Below are the players I've tried and their results:
Google Videos:
Reads MicroSD
Plays MKV (some without sound) but NOT XVID
Doesn't support subtitles
STABLE
Rockplayer
Plays XVID & MKV
No subtitle support
UNSTABLE
MX Video Player Pro
Plays XVID & MKV
Subtitle support
UNSTABLE
MoboPlayer
Plays XVID & MKV
No subtitle support
UNSTABLE
How have you guys been finding video playback on this guy?
I play on using this tablet for a lot of video consumption so I'd love to get this sorted.
Thanks for the help!
Dice Player has been gold for me, playing everything I've thrown at it (720p mkv, avi, mpeg). I haven't tried anything with subtitles, but it supposedly supports them.
There's currently only the ad-supported version available, but the ads are small and don't show up at all should you use microHDMI to display the video on an external screen.
MX video player has worked great for me. Try different encoders if something in your video isn't working well (ie, HW, SW, etc). Also, try re-installing if you think ICS broke it.
Diceplayer is the best I think. Plays everything just fine and have good setting for subtitle.
I watch my videos most with subtitle and i haven't had any problems. Easy to change size and if you long press on the subtitle text you can move it up and down. Also have easy access to change the subtitle sync. And the add only shows when the controls are showing. here You don't see the add when the video plays and the controls and status bar hides.
And if some videos don't play properly i say that the problem often is the video file that is encoded strange.
MX Pro works great for me even on my high profile x264 encodes. SW decoder works better than HW decoder (go figure right? I would have thought the opposite) with fast mode disabled.
Edit: I have to agree with Andreas, if you're having playback issues it's likely the video not the player. Encoding is a subtle art, not everyone gets it right. Get your vids from well known sources like Thora.
Thanks a million guys.
MX Player Pro doesn't support HW decoding on the Transformer Prime. At least on mine it doesn't. Dunno why. And its really flakey. It keep crashing out on any file I try to play (XVID, MP4, MKV)
DicePlayer is WIN so far! Thanks for the recommend!
It's playing everything with subtitles too.
The only thing I don't like about it is the background 'behind' the movie is a gradient from black at the top to grey at the bottom so on some movies you've got a grey at the bottom of the picture instead of it playing on a full black background.
Unless you guys know how I can change that I'll be using DicePlayer until something better comes along.
HURRY UP VLC!
HW decoding technically works on my Prime, but SW decoding performs better. Is the option not even available for you in settings? Free or Pro? Also, no VLC...ever. Just no.
OK!
Very happy to report that after purchasing the full version of MX Player Pro EVERYTHING WORKS GREAT!!!!
Many thanks again guys!
XDA ROCKS!

Another vote for DICE. Hopefully they can get their payment issues sorted out.
Dice is the best IMO. I run huge 1080p files and only Dice can handle it without a hiccup. MX Player Pro has a skip every once and a while. Not that big but Dice doesn't do it so it wins.
VitalPlayer Pro seems to work well. It can't navigate to the MicroSD card though.
BSPlayer has worked well for me. I use the lite version and all is good. It handles all video/audio as well has HW decoding for supported video types.
My vote goes to Dice player. It is the only one that I have tested that doesn't have audio lag when I am using bluetooth headphones. Also it plays everything I can throw at it.
And don't forget to instal mx player codec pack for armv7.. In market too.
MX Player will prompt you if it needs a codec pack installed. In the Primes case it does not, it is good to go.
Since I use and like DVD Catalyst 4 to convert my DVD's to video I also use their video app called Movie Gallery. Not sure if it plays all codecs but it sure works great with my converted DVD's
I used to use VPlayer when it was beta/free but now I use vlc for android http://cvpcs.org/blog/2011-09-18/videolan_for_android_pre-alpha
I get my TFP tomorrow but it works on my phone and the OG transformer according to the post so it should work on the prime. NONeon btw at least the OG was NONeon
I sure hope that it does.
video and sound on tv, subtitle on prime
I've tried Dice- and MX player and with both programs I get sound and video on my tv playing avi but the subs will be displayed only on the Prime. Has anyone the same problem or does someone a solution?
Does MXPlayer require an internet connection for the key verification? I saw some reviews that stated it did. Obviously on a wifi only device i may be without internet... Anyone have trouble with this?

You have to use software decoding if you want soft subs, the hardware decoder on the prime doesn't handle them when outputting.

[Q] crashing on video playback

Hi y'all
I dont know if my transformer is hard ware damaged or if i have a software problem.
Problem description:
I just exchanged my transformer prime for a replacement unit since the HDMI was broken on my old unit.
I reinstalled MX player and started playing a video (H264) and it keeps crashing. The player will kill itself and once, it even went into a weird stripe crash and had to be hard rebooted. I uninstalled the codec pack for MX player, did it on software encoding, no hard crash, but MX player keeps dying.
I tried vplayer, which doesnt seem to crash but the audio/video sync is off. Now I cant remember having this problem on my old unit.
I then proceeded to download the glowball demo to 'tickle' the tegra cores, in case its a cpu/gpu issue, and that worked fine without crashing.
unrooted, locked bootloader with all software updates from Asus.
i am out of ideas, any pointers what could be wrong / how i can locate the issue?
cheers

I have similar problem with u on the video playback, however I manage to play MP4 and MKV files without crash.
MV Player stops when I play any rmvb files which is quite annoying as most of my video are rmvb.
I wonder if it crashes the codec when we try installing different Video players.
saw a new video player on the forum and gonna try it tonight ~ hope this will work~
http://forum.xda-developers.com/showthread.php?t=1517415&page=1
lets keep talking about this issue and I believe some other users have the similar issue too...
wow VLC build for ARM, impressive
What REALLY is annoying that i get a "not supported" from the stock player. How come the standard Android 4 player does not know the h264 codec ?
Did it work?
Try moboplayer out too and see if that is any different.

I will next, cheers
I just tried the VLC port. it does the same thing of crashing (but its alpha, so hey )
edit:
just tried a xvid file with moboplayer, same crash
all the apps just stop playing the video and return to video select screen
i have seen a couple of Tegra 2 optimized players, nothing for tegra 3 yet?
edit 2:
mx player has an experimental build where you can increase the cores to 4 for sw decoding, havent tried that yet
cheers

I have the same on Tegra 3 - tried MX player, MX player with ARM 7 codec, Mobo player - they just kill themselves during the playback....
Will try more players, not sure if that will help at all...
Dice player seems to have the best interface other then mx.
But no crashes and everything runs with hardware decoding that I've tried.
I too am am having lots of mx player crashes after the jellybean update on my stock uprooted transformer prime. The stock player also crashes.... This never happened on ice cream sandwich. Anyone fi d a solution to make video playback more stable?
Try S/W decoder.
I had a similar problem just a few minutes ago. I deactivated H/W+ decoder and it worked perfectly.
Sometimes, hardware can't play everything. You should try and play these videos with S/W decoder.
I might be wrong. I just said what helped me.

Embedded Subtitles via HDMI output

I wish the prime would show embedded subtitles on the TV when playing via HDMI. Currently the A/V goes out HDMI but the subtitles still display on the tablet. I emailed the developer of the Dice video player and he said this is device dependent and would need to be fixed by the device manufacturer.
Hey Asus,
Fix the subtitle overlay issue so embedded subtitles are displayed via HDMI.
I wish this first day i bought ATP. I spent 30$ on Hdmi cable that now is useless to me. Only way is software decoding in player's settings, but when playing mkv more than 5gb all is very very bad. The best player than can show subs via Hdmi in software decoding mode is MXPlayer. I manage to play 720p mkv with subtitles and all was smooth.
Someone here said that we want much from a tablet, and if you wish a home HD player buy one like popcorn but that is another 300 bucks

Hi!
Same here... I got my HDMI cable yesterday, and had to realize, that it's useless for me. I watch everything with subtitles, and with H/W Decoding it's simply a no-go.
Unfortunately, this is not an ASUS problem, but it has to do with the HDMI Mirroring implementation of ICS (some people are reporting, that there was no such problem with HoneyComb?).
I really do hope, that Google fixes this issue very soon (hopefully in JellyBean).
I tried out many-many videos, and the conclusion is, that most files play smooth with a max. resolution of 720p in software rendering mode, but I've had some .mkv files (SD, not HD!) with embedded subtitles which simply stopped after about 30-40min. (MX Player) and I had to restart the movie (fortunately I could seek, so I didn't have to watch it from the beginning).
My conclusion is, that 1080p simply won't work, it's just too much for software decoding to play & downsample it to 720p for the output.
PLEASE GOOGLE FIX THIS!

exactly...made my dream to play movies on my HD tv via Prime impossible.. would love this to be fixed in the near future. maybe someone who tried a jelly bean tablet with hdmi could tell us if it works there.
