Tegra 3 Does Not Support AC3 Audio
Despite what everyone has assumed, there apparently isn't any AC3 support at all in Tegra 3. In other words, HW accelerated audio in an MKV
isn't even possible. Basically, NVIDIA gave us high profile video with no audio!

Notice that there is no mention of AC3 support!
Here is the link if you wish to check the specs yourself: http://www.nvidia.com/object/tegra-3-processor.html
The TF Prime, TF300 and Toshiba excite are all handicapped when playing video containing AC3 audio, such as just about every MKV.
The tf300 cannot play an MKV with audio in the built-in audio player. The video plays silent.
MX Player cannot play an MKV with HW audio. You must select software audio or else the video plays silent.
Only Dice Player can play an MKV with sound.
But, I suspect that dice player simply defaults to its own software audio and is NOT using HW audio acceleration.
The Acer Iconia on the other hand, has licensed Dolby Audio on board, and I suspect, has added codecs supplied by Dolby. It is my guess that THIS is the
reason the Iconia can play MKV's correctly.
It can play an MKV with audio in the built in player.(ASUS tf300, TF Prime, and Toshiba excite cannot)
It can play an MKV with audio in MX Player WITH HARDWARE AUDIO SELECTED! (ASUS tf300, TF Prime, and Toshiba excite cannot)
It can play an MKV with audio in Dice Player. (ASUS tf300, TF Prime can also do this because Dice apparently supplies SW audio by default.
Take away message:
Only the Acer iconia a510 has AC3 support across the board and can universally play MKV AC3 audio.
All other Tegra 3 tablets are at the mercy of the 3rd party video players and their supplied software AC3 support.
Of course in the real world, this may or may not be important to you. It is certainly possible to play MKV video quite well in Dice player on all of these tablets. However, if 3rd party support for your chosen player fails, you must understand that the built in players in these tablets will play silent with most MKV files. Only the iconia a510 does not rely on a 3rd party player for MKV playback.
As a disclaimer, I own both a Transformer and an a510 so I have no personal bias toward either. I am quite fond of both, and both have their pros and cons.
Supersoulfly: Quoted from previous thread,
Perhaps someone knows, was AC3 a problem with Tegra 2 also?
I personally am using the BS Lite player to get my MKVs to work. If Nvidia dropped the ball on this I don't see any other solutions than outside software.
--------------------------------------------------------------------------------------
Yes it was. In fact myself and I believe another member, emote were responsible for long threads showing how to split MKV files into two parts, remove the audio, convert to another format and put them back together. The objective was to avoid having to transcode the video. Tegra 3 is much better, because at least it can handle the high profile video well, and it has the software horsepower to do the AC3 decoding. Just seems that the problem really shouldn't exist at all at this point.
Course the next thing I would be curious to know, is if exynos or snapdragon processors support AC3. If they do, it might bias me toward them in the future.
The Transformer Infinity is rumored to have (or will have) multiple processor choices. I know I would be inclined to chose the processor that supports AC3 as well as high profile video, so that MKV files just play without all the software workarounds.
I'm not too interested in the infinity yet. Really would like to see how well the Tegra 3 (or snapdragon) runs at that high resolution first. That high resolution is new territory for Android and ICS, not sure how app friendly it will be either.
Just a random thought, but I would guess it has to do with licensing fees.

This makes sense. And Wikipedia shows that AC3 is just another term for Dolby Digital, which is why it was on the Iconia tab.

Of course it has to do with licensing fees.
But can you imagine buying a Blue Ray player or Reciever that can't decode Dolby soundtracks?
Dolby digital is a pretty common format.
And when you call the company to complain that your blue ray player or reciever won't play audio, they tell you to get an external decoder for the audio, our players just handle video?
If you question the importance of their decision, ask yourself:
Why did Acer think that it was so important to get Dolby audio onto the a510? Why did Acer pay the licensing fees that NVIDIA didn't? Because someone at Acer realized that the video player on the iconia can't play any videos. And the first thing the customer is going to do when he gets home is to dump the latest episode of his favorite TV show on his Acer tablet and see how it plays. And on the Acer a510 it actually does! So why was Acer able to think through what the customer wants, and NVIDIA unable?
Remember NVIDIA is not a small outfit. They make computer gaming chips that are designed to play and support just about everthing. To not support a codec that is present in just about every downloaded movie on the planet is strange. But remember this is the same company that designed a chip, the Tegra 2, that couldn't even play high profile video. I had to transcode every movie or TV show that I played on my galaxy tab 10.1 since the day I bought it.
Have you tried to play it on Dice player ?
I think you are misunderstanding. There isn't anything wrong with MKV playback on these tablets. Dice Player works well on both the TF300 and the a510.
The point is that, the absence of audio in some players, like the stock player in the TF300 or the HW audio option of MX Player has always been assumed to be due to a fault in the video player not using the HW audio decoding capability of the NVIDIA tegra 3.
I'm just pointing out that missing hardware audio - or missing audio altogether in some of these players is because there ISN'T any ability at all in the tegra chip to decode these soundtracks. If the programmer hasn't implemented a software decoding solution, you will get no audio.
Dice Player has a software solution, it decodes AC3 and you get sound.
MX Player has a software solution, you select it manually and you get sound.
The stock player depends on Tegra 3, therefore you get no sound in your video.
The a510 has a system-wide fix for the NVIDIA's lack of decoding capability. Acer paid dolby to implement the decoding that should have been native to our tablets, so any video player will work. Even the stock player.
I'm guessing nvidia didn't include dolby digital because it would be quite pricey to license it and they want to get as many companies to use their chips as possible
so they didn't include it but if companies themselves license dolby digital they probably provide hw decoding
Well about the audio AC3 , its does play Ac3 , about 2 days ago i saw a movie with ac3 audio and works fine, you only need to download the BSplayer lite and will play all formats ...

Yes, you can hear AC3 audio from this tablet. The thing is, it's being decoded via software, not the actual SoC. That is the OP's gripe. Hardware decoding requires much less work for the processor, which means better battery life. Plus, it would be much smoother and more consistent than software decoding.

I can barely play any codecs on my tmobile tab. Is it suppose to play Divx or xvid out the box? or do different carriers' tabs have different video codecs?
Also is there a stock video player app installed or can you only play out of the Gallery app?
I've already tried rockplayer and vplayer, both have video and audio lag for divx 720i videos.
ANd if other carriers tabs have more codecs can i install thme in my tmo tab?
The Tab plays more video out of the box than any other Android (or Apple) device I've ever used, and I've used most.
Now if you're trying to play videos you've (ahem) gathered from around the net, you will certainly find some that won't play properly. "Found" videos can have a truly phenomenal combination of audio codecs, video codecs, and bitrates, any of which might prevent proper playback.
While you cannot directly add codecs to Android (as yet), there are third party video players that will handle just about anything.
Rockplayer is one of these third party players. While it will play nearly anything thrown at it, it's not hardware accelerated (doesn't use the GPU) so it is largely limited to lower bitrate, standard definition videos.
http://www.appbrain.com/app/rockplayer-universal/com.redirectin.rockplayer.android.unified
if you actually read all that I posted you will see that i have tried RockPlayer.
And trust me I know enough about video codec, bitrates, and depths (Visual Effects/Graphics Artist) to tell you that I'm trying basic Divx and Xvid codec at a decent to low Bitrate and they are not working on Stock Video player and will not run smooth enough on rockplayer do to lack of graphic acceleration.
ALso, No the Samsung tab is not the Leader of COdec in the ANdroid Tablet market. The ARchos tablets (70,101 etc) lead in stock codecs by far (I own both a samsung tab and a 101).
Thanks... I guess
The only codec that is accelerated is h.264 in any container. So, mp4 and mkv work fine even at 1080p resolution.
If you encode your movies in h.264 and set Rockplayer to use hardware decoding mode down low in the settings, you'll have no problem viewing it.

It's true that the Archos can play a lot of video formats, but I don't put it in the same category as other top Android devices because it's so lacking in other areas.
Sorry I just perused your previous post, but I've truly had very few problems in playing video on the Tab, even with "found" videos.
In fully reading your post, my question to you would be, Why Divx? If you're encoding video specifically for use on the Tab, why not encode to h264?
I have the Sprint SGT, and I have zero problems with 720 mkv and avi files, regardless of who encoded them. The stock player renders them as smooth as silk. It also has a 5.1 mobile mode for AC3 audio tracks. And the control lock means I can wipe fingerprints off the screen off with my shirt without disturbing playback. My only complaint with the player is the lack of a skip button.
I have read other complaints from other SGT users about poor or stuttery playback, and I'm quite baffled. The only file that would play were 720p mov files. Other than that, I've had zero problems.
Rockplayer was awesome on the Evo, but its useless for me on the SGT. Its now useless for me on the Evo, but thats because I don't even bother watching videos on the Evo anymore.
Wait... I did encounter one problem. I downloaded the newest version of mkvmerge to split mkv files into <2GB parts, and those files will not play on the SGT. But I mostly watch TV and those files top out at 1.5 GB. But xvid avi is no problem. Dunno about divx for sure, I never really use it.
well i have problems with sound playing 1080p BRRip H264 AAC-.mp4 files i get no sound,does anyone know why?
Is this your own rip or did you... uh... find it laying around?
Thank you all for the replies.
Im using Divx and Xvid because those are the native file formats I'm downloading from a sever/email at work on to my SGT on the go. If I could I would convert to mp4 or h264. Is there a android video converter app that can do did?
Yes I heard that the Sprint SGT can play Divx and some MKV out the box (my friend has one), why is that? Different native video player? If so can I get it extracted for my Tmobile Tab?
ALso I never said Archos are on the top on android Tablet List, I was pointing out that they have Much more codecs out the box "Leaders in Codecs out-the-box"
Lastly Rockplayer is studding on me, giving me about 20-25fps when my video files are 30fps. Also audio sometimes lags on Divx and mkv files.
What is the latest version Rockplayer app out there or is there a better video app for SGT??
Have you tried VPlayer??? I prefer it over Rockplayer

Very interesting. I do have the Sprint Tab, perhaps that's why it plays almost everything I throw at it.
I'd never considered that different versions of the Tab would have such a major difference in codec support. I'd figured Samsung was responsible for paying the licensing fees for the various included codecs. Looking at the reality of these significant codec differences, it makes me wonder if the codec licensing fees aren't instead forced on the carriers themselves. That's the only reason I can fathom to explain the codec differences.
The Sprint ROM's are online here. My guess is that you could certainly pull the necessary files out of the Sprint rom and run them on your device. That said, I've absolutely no idea how the codecs are packaged and which files and libraries you'd need.
my tmo tab being a gsm device might not play nice with a sprint rom. And I have no idea how to take apart a rom or how to add codec to mine tab.
Anyone have any other options?
Also I have tried v player and same result as rock player
So far my tab has played all my video files with out a problem, (mostly .mkv animes) i have to use mkv sub extactor (from the market) to get subtitles to work. Rockplayer would go out of sync after 5mins of 720p .mkv
RockPlayer can play h.264 720p MKV videos using hardware acceleration as long as they don't have DTS audio (as many do when they are real BluRay rips). If you play TV rips they generally work since they are not using DTS. Dolby audio might work in HW mode as well, I am not sure.
You can play DTS audio though, but only in software mode . But the processor in the SGT cannot keep up with both DTS and h.264 in 720p. I think it might manage 480p with DTS though.

From what I've read, most incompatibilities between GSM and CDMA versions of the Tab have to do with communications related apps, limitations that should have no impact on the video app.
I would think it's extremely likely that the Sprint video app and/or codecs would run flawlessly on other versions of the Tab. Ripping apps from ROM's and deodexing them is not my forte, but there are many in the developer forums who are very experienced in that sort of thing.

Probably because it's a 1080p H264 file and you're trying to play it on a device with a 1Ghz processor, and no hardware acceleration for video playback. It can't cope.

If you read the app detail for mVideoPlayer, it only play videos/codecs your phone/tablet can already play. It doesn't add anything or help at all. It's just a skin that takes up app space.

Converts all my 720p.mkv files perfectly, the only issue is the files are big, 2-4 GB, but the quality is outstanding. They even play on 'Movies' which darkens the navigation bar.
i was looking for something like this so many times before, but I never found a stable movie app. On my Samsung Galaxy S II however, it's no problem at all. And that's a freaking phone man! But it's no wonder the hole system is so fast. It makes my newly aquired Iconia looking really sluggish and outdated :-( I don't know if I gonna keep this tablet or gonna look my movies on a 4.3" screen...
I asked Acer customer support whether they're ever going to support additional formats and they replied that they won't ever add support for MKV and can't comment on the rest. So official support for MKV is out the window.
Mkv isn't a video format, it's a container. It's just that most mkv's don't contain only baseline h.264, which is the only supported video format currently. The most benefit would come from adding support for main or high profile h.264

I know, it still doesn't help at all if the video player application or framework don't support the container format. I personally love MKV, it's handy to slap in two different audio tracks and subtitles in English, Finnish and the hearing-impaired version, plus any metadata about the movie itself. No need to hassle with several files then.

Indeed. I tried transcoding a 1080p movie to 720p in constant quality mode, both in baseline and high profile modes, and while the quality was the same the high profile one used a lot less storage space. With storage space being rather scarse on mobile devices....
Well, we can only hope. But I don't know if the DSP is beefy enough to decode high profile or if it can be re-programmed to support it. Some DSPs are hardcoded and can't be used for anything other than what they already do when shipped. I don't know anything about Tegra 2 internals so I don't know what to expect.

You can always copy one of them to the TAB and see if there is any change ( I doubt it)
Using a OLD 60gb usb hdd (literally 8 years old)
And it does not seem to matter - even with the low speed of an old external drive I have no issues playing video from it.
.Mkv -- Regardless of where it is stored is not going to work on the Iconia right now - i don't think there is anything anyone can do or change to fix that right now - the system will not?/can not? use the hardware decoder on mkv files - and software decoding, even for a low bit rate video file is always going to suck.
Hopefully 3.1 will improve our video performance - but I find it a very simple matter to just transcode a video file if the only source I have handy is mkv. Plenty of great and free tools that make the process pretty darn easy. I watch a lot of movies/TV on my a500 - and get a great experience as long as I don't throw .mkv files at it.

My understanding is tegra2 will support h.264 high profile up to 720p @ 20mbps, but only baseline profile for 1080p.
With regard to the container format vs video format thing, I'm under the impression that container format support can be added by an app - so even if Acer never support mkv in the default player, if they do add hardware high profile h.264, then other apps should be able to play an mkv that contains high profile h.264 with hardware acceleration.

From playing around with PRIMEE, mkv containers are split appropriately and if the video format is supported hardware decoding works. The problem is that there is no support for AC3 therefore majority of compatible MKVs will play very well but have no sound.
Unfortunately once software encoding is enabled we are back to the same stuttery playback issues.
I personally don't believe it's Acers' job to add playback compatibility, I personally believe it should be built into Honeycomb as a baseline. Honeycomb is a tablet OS and as such should be expected to play popular video and audio. codecs. Saying that, if manufacturers did add additional codec support it would be a solid competitive edge.

Ah, that's good to know, so with a baseline h.264 payload an MKV will play fine on stock?
I think it probably IS Acer's job to add codec support, frankly. At the end of the day we're talking about hardware acceleration, and Android provides the software framework for that to work, and it's up to the hardware vendor to make it work with their specific hardware.
Frankly I think Nvidia should be doing it though - it'd do wonders for Tegra 2 sales if they offered up code to support hardware acceleration for their platform on Android.
I guess you didn't really do your research on video playback on Honeycomb tablets, did you?
You can not blame Acer for poor HD playback when, frankly, this is a Google/nVidia issue. Currently no 10" Honeycomb tablet can playback high profile encoded HD vides--smoothly, if at all--without reconverting said movies.
There may or may not be a *real* fix in the future (quad core Tegras are right around the corner, so...), only time will tell.

I bought an ACER device so I'll blame them! Problem here is that the Tegra 2 chip is capable to decode and encode the formats at 1080p without problems! The fact that Google still hasn't taken advantage of this feature doesn't mean that ACER couldn't!! To back my words here is an example:
Samsung! The Galaxy S and Galaxy TAB (7") they have much superior video codec support! I'm playing 1080p movies just perfectly on the Galaxy TAB. Samsung have invested in codec support and optimized it for the platform (both Hardware and Software) The Hummingbird CPU is Single Core! So why can't ACER do it? Maybe because they never did something like this before? Maybe because the have done only the hardware till now and they don't have the programmers that can pull this of? Ones the managers at ACER understand that selling thees devices without enhancing the base that Google provides won't cut it, I think we will have a very good device (not that it isn't good now but...)

So does the Samsung 10.1 play 1080p videos smoothly?
From what I've been reading.. no. Frankly, watching a 1080p on a 10" tablet is pointless (which is what I'm assuming you're crying about). If 720p isn't "good enough" on a 10" tablet, well, then, time to buy a 17" laptop.
I watch a lot of anime and that would be the primary function of this tablet for me. I was wondering if this tablet could handle the 720p/1080p mkv files encoded in h624. and also if they support subtitles.
here is a test file for current 10.1 owners.
http://www.megaupload.com/?d=9ZQAFZIZ
I got lots of anime 720P MKV files. They won't play on any Tegra 2 tablet I've had, including this one.
There video player apps in the Market that will play MKV.. but they don't usually support hardware acceleration so it'll prolly be very choppy :/
There's not a tablet out in existence im aware of that can play MKV with hardware accel.. sigh.
Galaxy Tab 7" can, and I suspect the HTC Flyer could too.

Dave
First thing I do with all my anime mkv is to convert them to mp4 with the subs burned in, with Handbrake. I prefer this because it takes the guess work out of not knowing if this device will play such and such mkv, and everything handles mp4 nowadays moreso than mkv. Even Archos devices that are the king of media codecs and formats have problems with some mkv files even, because as a container an mkv file could contain a myriad combo of codecs.

Same here. I'm just using handbrake to convert all my movies to mp4 so there is no worry. Handbrake will let you queue up items so you can basically just let it run.

When the TouchWiz update comes out expect this tablet to get a lot more media friendly.
Mine would appear to play mkv files no problem, although I can't control them, fast forward or jump to a certain point, which means I wouldn't want to rely on it.

When the TouchWiz update comes out expect this tablet to get a lot more media friendly.

don't bet on it. tergra 2 can't handle the throughput of most high profile hd. it can handle some but it's very picky. it also chokes on ac3 and has a hard time with aac multichannel sound. i have some multichanel files that'll play and some won't.
tegra 2 is no media powerhouse. imho the archos 101 is still the best for all the files it can play, but it's quality is lackluster... and the screen sucks.
It doesn't do it natively, but MoboPlayer is a great app (free) for it. It will handle 720p MKV no problem.
it can handle some 720p mkv. its very hard to make a general statement for files higher than main profile and 2 channel sound.
tegra is limited on media playback. check all the other tegra 2 forums. this is the reason boxee box dropped tegra 2.
don't get me wrong, I love the tablet, but there are some limitations to expect with media playback. it's not even as goog as the gt7".

This.
Tegra 2 has awful performance in alot of areas. Video playback and portrait view basically slow it to a crawl.

I hardly think portrait view slowing down has to do with the hardware. More likely HC.
I use my tab for MKV's all the time. RockPlayer Lite handles it like a champ. Perfect audio and all. Scrubbing works fine too. Just select software decoding mode when playing the videos
I found a program caled XenonMKV which rips the mp4 out of the mkv container and converts the audio to aac. It's a much faster process since there is no video re-encoding involved and it works 'ok'. It still skips a bit but it at least kind of works smoothly most of the time.
EDIT: tried RockPlayer Lite Software & Hardware and it was still stuttery from time to time. (3500kbps 720p mkv and mp4 from XenonMKV)
I think if you had a Max bitrate of about 3mbps or less and it wasn't AC3 it could do it.

Did you actually test this ?
I'm very concerned about video support in honeycomb tablets, and in galaxy tab in particular. I don't understand why, but it seems this feature has been left behind in every honeycomb tablet, whereas SGS and SGS 2 handle 720p mkv with hardware acceleration very well in stock video player. I just don't understand what the manufacturers are doing.
I can't even transfer that large of a file on my tab. It hangs and stops at the end. Weird.
Handbrake is free and works like a champ to convert any file. I'm using it on the @pple tv2 settings with some minor tweaks

Just watched an mkv last night thanks to vplayer. No problems

this. also, if the movie is quite slow (not much of on screen action, etc) i had good results at around 5mbps too and mp3 audio.
Guys im looking for an app that can play mkv file, which one do u prefer? With hardware acceleration

Mxvideoplayer can play mkv 1080p video with H/W , though it only works with 8-bit video, not 10-bit profile.

how can i check my video is 8 or 10 bit?

You can check it by going to the video properties on your preferred video player on your pc,im pretty sure most mkv files are 8 bit.
is the 8bit restriction a limitation of the hardware, or of the (mxvideo)player?

Im not really sure about that but whenever i tried to play 10 bit mkv video on mxvideoplayer with hardware decoding, it gave me a black screen.
Dice
You might want to try Dice player as well, i had loads of mkv rips that would not play audio on other players but dice has never failed me on mkv's

I tried dice player it doesnt work. so far mxvideoplayer, dice player and moboplayer doesnt work for 10 bit mkv with H/W.
I'm not sure if there are any players that can play 10bit files at the moment. For general mkv's I've been using Dice Player as it has been able to play all my files on my Asus transformer which other players weren't able to. But since the exynos processor is far superior to the tegra2 I would think any player that has hardware accelerated playback will suffice.
Most recently I've been using BS player as well for playing mkv's stored on my NAS streamed over wifi. This is the only player that seems to be able to play 720p video smoothly over wifi.
Stock Samsung player can't play MKV like Galaxy S and Galaxy SII?!? It's the best HW player for my SII...

I use MoboPlayer, it can play almost video formats well.
But I also got aneesoft video converter to help me do some conversions when need, and it let me to play HD, and AVCHD videos that shot by HD camcorder smoothly.
Aneesoft? Never heard of that. I'm looking for a .mov converter as the tablet converter had trouble with my .mov files.
Is that the best converter out there?

Well, aneesoft video converter can convert the .MOV video well for my tablet, it has a special output selection for tablet, so you just need to choose your tablet model as output.
I'll echo the mx player recommendation; I like its rendering options and subtitle support among other things. Lack of hi10p support is a hardware limitation. Video with 10-bit color profiles is just too new and (at least afaik) isn't supported by any current hardware. And of course mobile cpus lack the compute muscle to decode decent-quality x.264 smoothly. So as others have said, transcoding on your computer is your best bet. If you don't know anything about video encoding, try http://hi10ptranscoder.wordpress.com/. It's a simple program for this exact problem.
For me Dice-player had stuttering every 10 secs on some .mkv-files. The stock player doesn't stutter, but it also doesn't support movies with DTS-sound.
MX Player seems to work the best and it also has an option for SW-decoding the sound if a file has DTS-sound. (Have to change it from the default HW-decoding to hear sound.)
No need to worry about 8 or 10 bit - there are NO rips with 10bit of any movies, 720p, 1080p - all are OK...EXCEPT some crazy anime, seen them - I really don't get this 10 bit hype - just some ultra-grainy stuff...
Stock video player can play MKV smoothly , why bother to use another player ?

Stock player doesnt play audio if the mkv contains DTS track.
MX Video player for me is the best. Without chainging the H/W decoding i just selecting the DTS audio track and plays it perfect.
I have done tests with heavy mkc samples with 20-40MBPS with DTS sound and it plays it so smooth. Smoother than my expensive O2 HMR-2000!
My oldest Galaxy S2 plays them perfect too but with same samples i have some frame drops some times even if i have it at 1.6GHz.
It seems tab 7.7 doesnt have excactly the same cpu/gpu. At papers it is the same. But not in real life. Maybe the memory or the controler or the chipset or the architecture? I dont know.
It plays PERFECT any mkv with DTS and it is an great media player. The only problem is to read NTFS HDD's. Because the fullHD / full length good quality movies is always bigger than 4GB's that the file system of TAB can read.

Ntfssd can read NTFS sdcard, Drive Mount can read OTG NTFS or EXT storage devices. These two app are free in Market.
I would have to chime in and say MX-Video player is the best especially on how it handles video stretching, the stock player cant really cover the entire screen and both dice and mvideo player zooms the image to fit the screen, only MX video player stretches it properly to cover the entire screen, pretty nice if your using a honeybar
I bought me a Lenovo Tablet yesterday and wanted to try out to play HD Videos on it.
Sadly my videos are lagging and the audio is async... I tried it with MX Player and Mobo Player, both installed the ARMv7 Codec. What i'm curious about is, that the Tegra v2 Chip should to decoding of 1080p h.264 Material in Hardware (my video was h.264 720p in a MKV Container) and both players showed me that they decode the video in software...
Is there any player that can play my mkv videos without lagging around? Or do i just need to adjust something?

Try different players but it's def not capable of 1080 and even has issues with 720p main and high profile
Sent from my Galaxy Nexus
mhh but the nvidia site says something different...
so the chip itself should take care of that... maybe its just a firmware issue?
The screen is 1200x800 so there's really no way to play 1080p on it. Even 720p is going to be cropped. The only way to do 1080p is over HDMI without mirroring but apparently that isn't very smooth so 720p seems like a much better option.
Tried a reboot and/or turning Wifi off/on again? It's worked for me.
Basically the chip can do it. The Tegra 2 has some special HW IP inside that will do the decoding. Most of the Tegra 2 tables are unable to use it because the vendors are not supplying the codecs and filters that make use of the HW block. So you are somehow limited to the codecs and resolutions that are choosen by the manufacturer/Nvidia. You can't change anything and as far as I know Nvidia also isn't distributing this part open.
I'm also quiet disappointed seeing that chinese pads with Telechips MCU (ARM11 single-core) can playback almost everything up to full-HD and the Thinkpad Tablet can't.
Dice Player.
It is the ONLY working HW accelerated player in my experience....
mkv files, everything plays well on it....
