I'm having trouble figuring out what's going on here. My Asus Transformer (Prime Rom, dual-core 1ghz Tegra with 1gb RAM, ~20gb free SSD space) Is having problems playing video. It stuters the sound (rarely), or the sound plays normal 1:1 but the video plays at a speed of 1:2 or worse (1/2 speed) so after a few seconds its unwatchable, not to mention that if I watch 15+ seconds it crashes the app. Also, if there are Subtitles, they keep pace with the audio without issue. on a few rare occasions, (notably 1 set of rips) the video plays fine but the audio is severely compromised where people speaking sounds like somone playing notes on a low-quality synthesizer...
Most videos are encoded as MKV (varying audio codecs, all the way from low-quality 56kb all the way up to FLAC)
I've played off internal storage, MicroSD, Dock+USB (flash and USB HDD), Dock+SDHC, none seem to make a difference.
My guess is that it's a app or rom issue, since my EVO (1ghz single core, 512mb ram, CYM rom) plays full 1080p video without a hiccup (while mirroring it over HDMI!!!).
Can anyone suggest a player that will play 720p without a problem? 1080p would be nice. If this is an Android problem, is there any kind of workaround without down-grading my videos? (I mean 480p already doesnt look great on my TF's screen, 240p would REALLY suck...)
You never mentioned what player you're using, but Tegra 2 doesn't support MKV containers properly, it needs to be fed raw h264 streams for hardware acceleration to kick in. The only player that does this is DicePlayer. It'll demux the mkv file and decode video with hardware and audio with software giving you lagless experience. Your experience with FLAC may vary though.

I tried the built-in video as well as "Mobo Player" which claimed it had MKV support.
Someone else on another forum suggested Dice, since it's got a free trial I'll be installing it this weekend and seeing how well it works. (While I would have preferred a free solution I'm willing to pay a few dollars to support devs as long as they're not asking like $19.99 or something for a dinky little app)
I'll report back if I can get it working later, thanks for the explanation!
Give Dice Player a try. It's by far the best player now. It claims to us the actual hardware instead of software decoding.
Hmm, do you have streaming problems too? For some reason, my netflix seems to be lagging in video now. It didn't use to (pure-root, no prime) then it did (prime 1.8? 1.6? can't remember but it was 1.x), didn't lag (2.0.1) but is now laggy again (2.0.3 or whatever the latest patch is).
I'm getting mixed results.
Yes, a certain number of videos will play now, but some still wont it still says it's unable to use hardware decoding. However these are 720p and 1080p (480p plays fine now) so I'm wondering if it's an HD issue... (Yes I did install the Tegra Plugin) So it _IS_ an improvement... I'll have to compare the encoding info to see what else is different between the ones that play and the ones that dont...
Overall, I am pleased with Dice and will likely put up the $6 the developer is asking for. it DOES appear to be Hardware decoding and hopefully it will only improve from here (considering my EVO, with half the specs, can decode + Mirror 1080p I assume this is an issue that will be resolved with time and dev work on the app/plugin)
@ asdfuogh:
I've not done any updates. I bought it used with Prime pre-installed, so I cant really compare. I dont have netflix but I'll try some of the longer youtube streams and see if they hiccup (I was having issues earlier with youtube but I was also on cellular so I had limited bandwidth to work with)

The thing with Dice is, it'll use Hardware acceleration for Main Profile 1080p (I forgot what level) and High Profile 720p with certain reference frames, etc. Exceed it and Tegra 2 can't decode it so it becomes software. I believe the full specification can be found through a search "tegra 2 h264 decoding profile"
After digging through the dumps of the videos I found my problem.
I mislabeled them...
What I labed as "720p" had a resolution of "1920x1080" I had switched to true HD recording about the time I got my BluRay drive (as opposed to my old HD-DVD drive) and for some reason screwed up and labled some BR rips as 720p...
After comparing the dumps and re-labeling, I've found nothing 720p or lower that Dice wont play (and with shocking efficiency! 2-3 hours of 720p playback (mostly over internal speaker) from my USB HDD and I am still at 97% power!!!
I'll still look over the codecs that Tegra can support, maybe I can find a way to get a "low profile" 1080p sometime, but for now since I dont have anything except my PC monitor that can exceed 720p, I'm good ^_^
Thank you all for your help!
EDIT:
Nevermind the 97% bit, I forgot the dock had a seperate battery, the dock was down to 16%... though I think that's still impressive for what I was doing...
MX Video Player is the best.Install the app and the Tegra plug-in.

Unfortunately hardware decode of HD H264/AAC files is still broken with HC 3.2.1. It used to work with 3.1, but got broken with 3.2. It doesn't matter which player you use.
I have a ticket open with Asus. They initially said they would fix it in 3.2.1, but didn't. When I then told them this in the ticket I had open, they said "nobody has reported a problem". This is in the very same ticket where I reported the break 2 months ago! I got quite cross at this point as it clearly hasn't been passed up the chain.
Anyway, they have promised to look into it. I've supplied them with a file that plays back with hardware decode in 3.1, but doesn't in 3.2.X. Let's hope they sort it out soon.

I have to agree with this. MX Player is all I use now. It will dim the button bar and notifications, blank the tablet screen when connected to HDMI, and can easily play back all my (previously) problem mkv files with hardware on the video and software on the audio.
And its free, something DICE player cannot claim.
Rockplayer
Try Rockplayer.
I have a weird problem. I've used skifta and UpnPlay for DLNA. Both of them work great at finding media. When I play the media on moboplayer or MX Video Player the video starts and everything looks great, but then after about 10 to 15 seconds I loose the sound. The Video continues to play and looks good, but no sound. If I advance the video the sound comes back for about 10 to 15 seconds and then it goes off again. Then if I keep doing that the media player seems to lock up.
Is anyone else having this issue? My source DLNA is windows media center 7. Can someone else try this an let me know if you experience the same problem?
I think this is the usual HD issue with Tegra2. I bet you would have the same problem if the files are local.
(This is the main problem I have with my GTablet w/HC. Otherwise it would be a good tablet).
For my TF, I have to encode videos as AppleTV 720p (this will choke my GTab exactly as you experienced)
Okay, now that's strange. Today I updated my P5113 to UEBLH3 (newest official version) and that strange problem still exists.
H/W acc video codecs seem to dissapear after short using of the tab. When I restart sometimes I can play videos, sometimes it says "Sorry, this video cannot be played." Mostly affected are DivX and xVid avi files. Other players don't work in HW mode also. I hoped that updating to latest firmware would fix the problem, but apparently it's still here for me.
Is there anybody else who experiences something like that?
Try dice player work good with hardware acceleration

Thats not the point. The question is how come system video codecs stop working just like that? They arent accessible from other players also. Like the OS doesnt support HW acc. I want to use stock video player since its the best player for me (and plays all videos FULL screen)
Hi all,
I am using MX player to watch videos and it seems to lag with some MKV files. There is no lag on avi/mp4 files, and sometimes even some mkv's work. Recently though I am unable to play any MKVs without lag. I'm unsure if this is how the system works, but I am unable to use the HW/HW+ decoder on any MKV files.
Today I flashed a custom rom onto my galaxy tab 2 and tried overclocking, but I haven't noticed any difference. ( I may be doing something wrong). It seems that I have the same issue with other players too.
If someone could help me out, that would be great. I'm not sure if I need a settings change, new player, different overclock values, etc. Hopefully it's possible to watch my MKV files
Also if someone could also suggest if there is a certain rom that helps too I'd appreciate it.
When playing MTS files from my Sony HandyCam on my Samsung Galaxy Tab S 8.4 using MX Player, I get horizontal lines that degrade the quality of the video. I tried some other Android players and they were even worse. I've sometimes seen a similar thing in Windows Media Player on my Win8.1 computer. In researching it, I'm finding that it seems to be a problem going back quite a ways that may be related to the file format more than any particular device. It also seems it may have to do with interlacing. Has anyone seen this in MX Player with MTS files? There is a setting that indicates you can deinterlace, but it only works with the SW Decoder, which I turned on, but then there is a different problem - choppy playback (always) and distorted images (at times). I'm hoping for a better solution. Is there one?

As you said Deinterlacing will only works with SW. SW decoder uses ffmpeg. So, it may render well in many occasions. But, it needs lot of cpu power. So, it may laggy in high definition videos (depends up on your hardware).
Both H/W & H/W+ uses system decoders. So, MX Player's control over it is very limited.
