There are a lot of MP4 video clips that I cannot get to play on Xoom smoothly but they play back really well on my HTC Desire.
On Xoom the video is laggy while the audio is audible. This happened to both 720p and 480p videos. I used both the default player and Moboplayer to ensure I am using the hardware acceleration.
Strangely on my Xoom the Moboplayer can soft-decode 480p MP4 with ffmpeg and playback without any problem. 720 is smoother but the decoding was too slow which resulted in A-V async.
Again, all those clips play really well on my HTC Desire. Tegra 2 should be able to handle them.
Anyone knows anything?
Please search the forum before asking questions. This has been asnswered.
The problem you're having is to do with the clips using high profile encoding.

There's lots more. All I can say is, learn to love Handbrake and be prepared to have your computer running all night every night if you ever want to watch HD movies on this thing.
I dont agree; I have transcoded 2 blue rays, hellboy and start trek 2009 in about an hour each, using my imac and handbreak
Oh, and download Vitalplayer from the market for the best hd video playback..

Yeah, well, I don't agree.
I converted 2 720p mkv 90 minute movies and a 40 minute 720p mkv TV show last night and it took 6 hours. This was done on an Intel Core 2 duo P750 2.26GHz
Not everyone has the same hardware. I suppose I could run out and buy an i5 or i7 for the sole purpose of encoding video for the XOOM.
Maybe Motorola can partner with a PC company. How about 20% off a new laptop when you buy a XOOM that way you will be able to take advantage of its HD video capability in 2 hours instead of six.

It all depends on your settings, and keep in mind that the imac is going to have similar hardware to your machine. The recommendation is to set max width to 1280, set B Frames to 0, turn off CABAC, 8x8 Transform, and Weighted P frames. If you do that, you'll find fairly consistent encoding times even with older hardware. Also, keep in mind that encoding is entirely processor bound and will do better the more cores you can throw at it.

Been there done that. There are no shortcuts. Good quality takes time or more cores. Or harness the GPU ie CUDA but that causes horrendous macroblocking in bright scenes.
No matter how you sugar coat it, re-encoding video is a time consuming pain in the ass for most people.
I also seem to remember there are multiple versions of the imac, with variable hardware specs, from dual core up to quad core 3.6GHz - so your claim of similar hardware seems unlikely.

Suggest using 800 max width for substantially faster encode speed and smaller size. Quality diff is negligible on a 10".
If using 2-pass, switch to 1-pass for both faster encode time AND better quality.
Unfortunately, HB doesn't provide x264's speed presets. You can gain additional speed (at cost of some nominal size increase) with the faster presets. Hmm, I should update my HB script to allow "downloadables" as input.
>The recommendation is to set max width to 1280, set B Frames to 0, turn off CABAC, 8x8 Transform, and Weighted P frames. If you do that, you'll find fairly consistent encoding times even with older hardware.
Encoding to baseline profile (what the above basically means) gains speed by disabling more advanced "compression" features. The trade-off is significant size increase, about +30% vs high profile.
Using a lower res allows more efficient settings. At 800 width, you can use main profile. Speed diff between main & baseline is insignificant. Speed gain for the lower res is substantial.

I appreciate that your trying to help, but those are the settings that I have been using already: 1280, set B Frames to 0, turn off CABAC, turn off 8x8 Transform, and turn off Weighted P frames....
and it is still taking well over 3 hours to re-encode a 1:30 movie.
I understand that lowering the resolution will decrease the encoding time, but I consider that a last resort compromise. In fact I would consider that basically a failure of the XOOM.
I have considered buying an i5 or i7, but I feel stupid buying a new laptop for the sole purpose of encoding for the XOOM, when I could just pick up my Galaxy Tab and just play these videos immediately. No encoding. Just copy them over and play.
I am quite sure those videos are not high profile. Their bitrates were around 2M, way below 20M.
And, as I said, I can even do soft-decode to play the 480ps which does not play well with hard-decoding.
480ps, man. 480ps. Stunning.

I don't really care about the encoding stage, I have an i7-950 which encodes a blu-ray in handbreak in well under an hour.
What I'd like to know, is are the codecs really this lacking, and will we see a solution?
I, like the OP have a HTC Desire and I could be devastated to find the XOOM can't handle the videos my Desire can.
Does it natively support mkv? I like to watch TV episodes in mkv like the 86MB Big Bang Theory episodes.
All my non-TV stuff I rip myself so I'm not concerned. Other than the DRM wmv I buy. Which play back fine on my galaxy tab.

Most TV shows that are 720p mkv, and are privately enoded, and downloaded, average about 1.2 GB and will and not play. Support for MKV as a container isn't a problem, its the profile of the h264 video in the container that is the problem.
If the Video that you like to watch is only 86MB, that doesn't sound like high profile 720p. So it might play, only way to know is to try or download mediaInfo and check its properties.
Good to hear that the i7 that you have can do a blu-ray in an hour. That sounds like what I should do eventually. Wonder if an i5 will do as well. I've heard that the i7, though it has 4 physical cores, is seen as 8 due to multithreading, wheras the i5 is limited to 4.
I watched two re-encoded episodes of fringe last night, and the Video on the XOOM is really amazing. It actually is almost worth the wait.

They're not 720, but they're nice enough on my Galaxy Tab. They are High Profile @ L4.0 though which I'v heard a lot of bad-mouthing about on the forum lately. I'm no expert on media codecs and frankly couldn't care as long as theyre watchable. I'd love to know I could rip my Blu-Rays at 720p and watch them on the XOOM comfortably though.
What you are posting is interesting. Its high profile, but low bit rate. Some of the early claims for the Tegra 2, which is used in the XOOM, said it actually could play high profile but only at a low bit rate, but I haven't heard it confirmed. I suspect this video will not play, but later on I will try encoding a video in a simliar manner to yours and see what happens.

Great, if you like I can dropbox the file I have and PM you the link for testing. These files playback flawlessly using the Galaxy Tab with every single player software I have tried, whether hardware or software decoding. FOr them not to play on the XOOM would be a killer.
Got your file. Sorry, it plays but with no sound. I tried RockPlayer and Moboplayer and the System Player and all play the same - silent.
The Video is actually pretty good. Smooth and very acceptable. So I guess it can technically play high profile, very low bitrate files - just not with sound. Have to Play around some more and see if I can learn anything else that might get this to play correctly or figure out what the problem is.
Edit: Actually, this is a Divx encoded file, not h264, so that is why it plays. So I am a little surprised about the lack of audio. And its only mp3 audio!!! This is really amazing. I can't believe the XOOM isn't playing this correctly. Has to be a way.
Update: Ok, success! It does play correctly in Rockplayer in software decoding mode. With sound. So it looks like you will have no problem.

Interesting, if somewhat concerning that it won't play this in the standard players or with hard-decoding even though it uses mp3 audio.
How about VPlayer Advanced? I find this plays most of my videos nicely on the Tab.
Probably just lack of Divx support in hardware. Thats not a big deal, even a single core CPU of lower power can easily decode low res, low bitrate Divx. I don't consider that a flaw at all. Software decoding video like this with the XOOM's dual core A9's is trivial. Results are fine. Just need an app like RockPlayer that does it. XVID files will probably not work in hardware either.
From Motorolas website:
PLAYABLE FORMATS
AAC, H.263, H.264, MP3, MPEG-4, ACC+ Enhanced, OGG, MIDI, AMR NB, AAC+

Yeh that's pretty fair I guess. How do you think it would manage if converted to MP4? I can do it on my 950 when I get home and send you it if you like? I'd not mind converting the whole lot if it played in the stock player.

As a proud owner of both a HD2 and a GoPro Hero HD helmet cam, I was wondering whether there's a WM video player that can handle 1080p H.264 encoded mp4 files.
I'm not asking for fluid playback, obviously, just a stuttering preview of picture quality while I'm away from a real computer.
Coreplayer has a 1008p limit hardcoded into it, from what I understand, so that's not an option. TCPMP didn't work either when I tried.
Any thoughts?
Forget it straight away. Even a 1.2GHz core 2 duo (which is already easily 10 times more powerful, if any comparison is possible) can't even play 1080p h264 at half speed...
The HD2 can barely play DVD res MPEG2.
1080 on HD2? useless... nonsense
as kilrah said... forget it
but one point is not true u can run 1080p X264 movies smooth on a pc with 1.2Ghz Dual Core.. now comes the point! IF... u have a graficcard that supports VDPAU. so even a loosy GeForce 9400 can do that.
XBMC installing as OS. turn VPDAU on.. e voila. smooth HD movies.
on my mom's AsRock ION330 (Atom CPU) with ION GPU (Equal to GeForce 9400M). 1080p movie with x264 in MKV container run's smooth.
and CPU usage is at 12-40% depends on.
have fun
Have you try the "Remote Desktop Mobile" feature....? Which is not "directly" playing on HD2...
I'm not sure if you fully read my original question:
I don't want smooth playback, I know I can't have that,
but simply a way to view stills out of a large h.264 file.
I don't care if rendering one frame takes several seconds.

Since the video files are on my phone, I don't see how Remote
Desktop Mobile is going to help me. Or did I misunderstand
what you are saying?
Yes we did fully read... But do you really think a developer would spend time making a WM program to open and decode a format that no existing device could play?
It's actually something the WM port of vlc could do, if it hadn't been discontinued in 2006 before it could play h264... It had the same capabilities as on other platforms.
@jisin: Of course if you cheat with hardware acceleration But my example was meant to put things on the same level, as the HD2 has none.
Nobody is talking about a seperate program - at least I wasn't. I would think
any player capable of decoding h.264 should handle 1080p, at least in theory.
For example, I don't understand why CorePlayer has a limit at such an arbitrary
number built into it, otherwise it would probably work just fine for my purposes.
TCPMP is witchcraft, as far as I'm concerned, so I don't readily know why it
won't play HD videos.
AFAIK the profiles used to encode HD h.264 are different from the simple ones used for SD videos, and thus need explicit support. The difference between AVC and AVCHD.
For example in VLC, support for HD h.264 has only come last year, long after SD one. Before that, trying to read one would just give you a couple of crippled frames and crash the player.
Just to clarify, AVC and H.264 are the same, or rather AVC is part of H.264.
AVCHD is an extension of H.264/AVC. That's what you meant, right?
In any case, my videos are AVC and not AVCHD encoded.
I really don't see how decoding a higher definition variant of a video codec can
be any different from standard definition, other than the stress on the hardware
of course.
If not coreplayer, then I think nothing.

Coreplayer's limit is 1008 horizontal pixels, I think, so it can't even play 720p, let alone anything higher.
I have a 720p video clip on my phone which will play in HTCAlbum or Pocket Media Player. It's jerky as hell and completely unwatchable, but it does play. You might find a 1080p clip would play in it too, I don't know. But it wouldn't give you any kind of meaningful preview.
I dont understand why you would want to try and view the image quality of a 1080p file on a 800 x 480 screen? It's never going to look any better than a similarly encoded 480p file. I would agree that it's handier to not have to re-encode files, but most 1080p files are downloaded as mkv anyway, which means that you would need to reencode into MP4. You may aswell reduce the resolution to 800 x 480 and save loads of memory while your at it.

You didn't get the point. He has a camcorder that doesn't have a screen. He wants to put its memory card in the HD2 and have a glimpse of what he just shot could have been like.
But yes, it would only allow checking framing if it took several seconds to load each frame, not much more...
WMP plays the sound, not the video, HTC Album came up with an error I think.
And yes, kilrah, that's exactly it. Should have mentioned that the camcorder
doesn't have a screen.

i downloade ttansformers hd (1080p) from youtube and coreplayer played that completely O.K. but i couldn't got it to play almost most .mp4 ones. it plays some .mp4 but doesn't many. also plays raw 640x480 videos from my digital camera not smooth but acceptable.
Camcorder that doesnt have a screen???
720p dont play in hd2 forget about 1080, it cant handle the resolution or the bitrates.
I don't know why Microsoft/HTC didnt done things right.
I have HD2 dual boot with Android.
where WM unable to play 720P but Android on same HD2 play 1080 smooth and crisp with out any frame delay/skip.
I think Microsoft has to optimize there graphics driver to come at par with Android.

Anytime I try to play a video file that's 720p or bigger it the Video Player comes up with an error window saying "File cannot be displayed or played". I've tried playing the videos in Rock Player and they don't work there either (either jittery, don't play at all, or only display the first frame while the sound plays in the background).
For reference: all the files are in the mp4 container and are h264 or standard mpeg file type. I've even tried using TubeMate to download videos in 720p from YouTube and those don't work either. I've tried using an external MicroSD and same error.
All of these files work *perfectly* on my Galaxy Tab and any computer I try them on.
For reference, although it wouldn't make a difference, I rooted the device the second it came out of the box.
did a bit more research...found weird things.
Transcoding my videos to FFmpeg (still 720p) even up to around 2,000kbps (didn't try higher) bitrate...the videos worked fine. In h264 they didn't work at all. Currently transcoding a video a few times to test a theory...but I'll report back in a few minutes.
Ok even transcoding the videos smaller than the screen display size (960x540) doesn't make them work if they're in h264. I'm completely lost on this... I'd appreciate someone else trying this stuff out too and seeing if it's just my phone...
Tegra2 has no NEON support so neon version of Rockplayer will not work.
Also Tegra2 cannot decode high-profile H.264 video, which might be your case.
So can it run 720p mkv files then?

MKV is a general "container", the actual video is conpressed in different ways.
I'm not really familiar with the difference between high-profile and baseline, but lacking such support is disappointing.

These are the settings that worked on the Zune HD, a device with the original tegra chipset from nvidia.
Those settings would be transferred over to that device without being re-encoded by the software, so I figure they are pretty much guaranteed to be supported by the Tegra 2 unless nvidia removed some of the featureset.
You should only have to enter the settings once unless you start manually changing the profiles..

Well I'm trying a transcoding right now with the commandline settings from the post above...it definitely takes a *long* time to encode with these settings (at least 3x as long).
At this point it's just better to encode in FFmpeg. It encodes *very* quickly and the loss in quality is unsubstantial for same-size files.

I didn't really think about the encode time.. I have an i7 at home.. so it only took about 20 minutes for the average hr long tv show..
Maybe if you've got a shorter clip to test it would work better.. I'd love to see the actual video specifications for the Tegra 2.. but nvidia hasn't seen fit to post the exact profile specifications.
This makes me think we may be out of luck for high profile h264 on tegra 2 platforms, though..

heh I'm encoding on a Q9550 OC'd to 3.6Ghz. One of the best processors available for transcoding files aside from applications that use both the CPU and GPU in conjunction. It doesn't take *long* but for a 4minute 720p video (around 120Mb) it took almost 8 minutes. Encoding the same video with the normal H.264 profile takes about a minute and a half. Encoding it in FFmpeg took about 35 sec.
This make no sense at all a captivate will play L.3 720p MKV's all day and this phone chokes on lesser material? Something is wrong here, plus the whole excitement around a dual core tegra chip is that you will not have to re-encode anything just drop a file and play. In the brief time I with it today it was chocking on almost any 480p or higher video I threw at it. I also tried multiple video players from the market. These same videos even played fine on a inspire 4G except the L.3 720p that only play on the captivate.
After doing some more research apparently the tegra 2 for all its power sucks at High Profile H264. Which is almost every H264 file on my PC and on the internet. Since my captivate plays High L3.1 720p's I thought for sure this would.
Sigh I guess this isn't my dream phone...
Can someone upload a video to youtube showing the quality of 720p video running on Atrix???

That's the thing...I encoded a few videos in other codecs and they worked great...even at 1080p and over 2,000kbps bitrate (basically what BluRay ends up converting down to for the most part). The processor wasn't even taxed at *ALL* (something like 18%). The problem with the high-profile H.264 is that the Atrix refuses to play it...not that it struggles with the actual video output.
The thought is that the tegra 2's gpu cannot hardware decode high profile H264..
What codecs did you use that worked well?
Ipad 2:
Video formats supported: H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format
XOOM:
If you stick with H.264 Baseline Profile, you can achieve up to 1920x1080p at 30 fps at 20Mbps.
Baseline Profile means:
- No CABAC entropy coding.
- No B frames
- No 8x8 transforms (DCT)
- No Weighted Prediction
For 1280x720p at 30 fps, you can go up to 20Mbps and Motorola XOOM should still be able to handle it. More Realistically, depending on the content, you can get away with 4Mbps and up with varying degrees of quality. If you are tight on space, use 4Mbps. If you want something to look good you can use 10/12 Mbps. At some point though the higher the bitrate will only translate to decreasing amounts of quality improvement. In other words, 20Mbps will probably look as good as 15Mbps, but will just use up more space. Ultimately, there is really no one size fits all solution and it may take a little experimentation to find the settings that work best for the content you wish to view.
Additionally your device does not have a limitation on certain types of B frames (Main profile tool). So you can add in B frames and not affect performance that much. If you are using a encoding tool that uses B frames, such as QuickTime Pro, you should be able to achieve main profile encoding.
If you are using a lower resolution that 720p (such as 720x480 resolution size) in order to encode longer length video , you can get away with using more tools (High and Main profile tools). However, encoding become more complex and may require more experimentation to achieve acceptable results.
In general, if you are concern about performance, use baseline tools and possibly b-frames (with no weighted prediction). This will give you the best performance.
Also as side note, if you are upscaling from a DVD to 720p try to use the best upscaling algorithm provided and don't expect to get true 720p quality from upscaled DVD.
Looks like Xoom is a tad bit better in terms of supported Hardware video decode capabilities.
In terms of GPU - it seems that the Ipad 2 may have a bit of an edge with the new power VR 543 - though this is not official as there are no direct comparisons yet.
Well my Epic4g with the Powervr SGX540 plays back high profile 720p FLAWLESSLY. The iPad will be capable of much more than that with the newer chip. The video standards that they "support" are the ones that they use through itunes and in no way represent the highest possible encoding of video that will play back. The instant XBMC hits the iPad2, I expect at least 1080p main profile to work since 1080p high profile ALMOST works on the iPad1.

What's that you say, the iPad can output 1080p? Well sort of. The iPad can mirror its 1024x768 display in 1080p but it still won't decode 1080p H.264 videos, and we don't know what type of TV you have, but we'd bet ours does a little bit better job of scaling than the magical iPad. All that being said, the iPad 2's new form factor will increase its desirability as a couch companion --not to mention we'll buy anything with magnets -- but an HD source device, not so much.
That's from engadget

There are a lot of threads about xoom video limitations.
Am I the only person who just copied dvd rips from my iTunes folder straight to the xoom, and watch them with zero issues?
Maybe my handbrake settings arent top-notch, but the quality/size trade off worked fine on my old I pad, and work fine for the xoom. If I wanted full crazy HD, i'd watch from the blu-ray disk directly, on a TV that does it justice.
Am I crazy?

It won't do it officially. Once it its jailbroken though it will have xbmc and will have ridiculous capabilities. For example the current ipad can play 720p high profile with xbmc now.

How long did it take from the MOMENT the iPad was released to when that became supported by some app?
People act like just because there are no apps RIGHT NOW for the xoom to play additional formats that there never ever will be.

It took a while for XBMC to be ported, 9 months or so. Dont know if they were working on it that entire time. The reason people act like that BTW is because the Tegra 2 is incapable of hardware decoding [email protected] or higher. Here is the guy who ported XBMC to the iPad and AppleTV and who was tasked with porting to Tegra 2 devices talking about it:

Believe me, I wish that were not the case. Wants me some Xoom or Galaxy Tab 10.1 action.
Correct me if I'm wrong but the only thing difference I seem to see from baseline and high profile h.264 is compression. My Xoom is fully capable of displaying the converted 720p mkvs with no chop/stutter in widescreen format on its screen. I've yet to test out hdmi out to my TV though.
Unless you want to talk about bitrate, but I can hardly tell the difference in quality loss vs source on something that I downloaded off the internet.

Oh there is no doubt that you can convert the video to play back perfectly on the Xoom. That isn't in question. I personally just think its ridiculous to have to.

Thanks for the read, I skimmed it and it pretty much sums up as higher compression without visual quality loss. I never put it together that the development of high profile was used for bandwidth savings though, interesting.

Thank you for your posts, and yes, I COMPLETELY AGREE with you! Once I began my due diligence today comparing the iPad 1, iPad 2, and the Xoom I thought to see if high profile h.264 was supported.
I was shocked to find out that the Tegra 2's hw (and Nvidia has confirmed this) does not support high profile h.264. BUT.... the iPad 1 does?! It's ridiculous quite frankly, and in my eyes, Tegra 2 is partial failure because of it.
Anyway, iPad 1 handles that Planet Earth clip (i.e. the de facto pseudo h.264 720p/1080p benchmark for years it seems!) beautifully. How's the batter life when watching h.264? How long can you get? Also, I would think the iPad 2 is capable of 1080p high profile yes?
In any event, I won't be buying a zoom. For the steeper price point, that is just insulting. I'm gonna try to find one of the remnant ipad 1s from Verizon that have been creeping around for ~$300, however unlikely at that price point it may be to find!
Kudos to your efforts and exposing this massive fault in the Xoom. I have NEVER been a fan of reconversion of the years, from divx in its earliest days through xvid (when apple ironically pushed 'reconversion' into mainstream)... glad that w/ this bad boy that won't be necessary as I'd never do it, too much hassle and insulting, imho.
Not being able to play 720p videos is the main reason I returned the xoom. If I am forced to convert videos I might as well do it for the ipad.
I am so tempted to sell my xoom because of this video playback issue...
I have a lot of bluray rips and I cant watch them on the xoom.
They were encoded using the Apple TV2 preset in handbrake, which I'm guessing is high profile
Oh wow, if this is that serious most of the Honeycomb tablets will be losing quite a lot of sells. I hope Samsung doesn't use the Tegra in their tabs. I'm fine with their Exynos, assuming it has the amazing codec support their Hummingbird does.
Its not the chip ( http://www.nvidia.com/object/tegra-2.html ) supports 1080p h264 just fine. As it stands right now, best I have been able to gather, it is a software/firmware (likely drivers) issue causing the poor playback.

The Xoom can play baseline 1080p h.264. The Xoom cannot play 720p high profile h.264. I would venture to guess that 90% of all video that people have that they didn't videotape themselves is high profile h.264 with 9.99% of the remainder being main profile h.264.

The iPad 1 handles the Planet Earth clip perfectly, but do realize that it is a jailbroken iPad with XBMC installed. The iPad does not natively support high profile h.264 even though the hardware is capable, because Apple wants you to buy media through iTunes.
The iPad 2 SHOULD be capable of 1080p high profile, but we won't know for sure until it too is jailbroken and XBMC is installed/optimized.
So, bought the Gtab on Friday, got a 32gb unlocked (Sweet). So, here is the problem that appears to be happening to almost everyone.
My video playback is Horrible, I've tried multiple codex's, and different Resolutions.
The videos so far i've tried.
3,343 Kbps 1280x720 at 29.970 fps, AVC ([email protected]) (CABAC / 4 Ref Frames) .MP4 Container, Very Choppy.
1,390 Kbps 640x272 23.976 fps MPEG-4 Visual (Xvid) Advanced [email protected]) (BVOP2) .avi Container Very Choppy
5,000 Kbps 1280x720 29.970 fps, VC-1 (WMV3) ([email protected]) .wmv Container Plays Flawlessly
Everything but the .wmv will play flawlessly on my Vibrant. Actually .wmv's are the only thing that i have found that won't play on my Vibrant.
I will test more configurations, but so far i'm not pleased with the video playback on the galaxy tablet.
I've tried other video players off the market, Moboplayer, mVideoplayer, haven't tried RockPlayer yet, but i had it on my vibrant and I felt the playback was not as good. Maybe i'll try it on Honeycomb.
So, I guess list your experiences so far, and suggestions. I will update as I go and find things.

Unfortunately, the fact that Samsung kept their hands out of Honeycomb has a downside. As far as I know, the Tab supports no more video types than stock Honeycomb. Which results in almost no good support at all. I've come to deal with it and you can, too.
The majority of my videos (720p and 1080p mkv) are converted and compressed while maintaining the quality by using this setup:

Who thinks Sammy should use Exynos in the tab? Tegra does not seem to be very friendly with respect to playback. I find it tough to believe that Tab looks so sluggish compared to GS2.
Just download a different movie player app. MoboPlayer works great, and it's free.

Whats wrong with just converting everything to hi-def MP4 on your desktop/laptop and dumping on your tablet? I mean the iPad does it with great success and gives the user the impression that it can play every video format??
The tab is a 10" screen, just about any video format 720p and above (hell even some 480p) will look just as good as 1080p on your 40-50" tv screen....or am I missing something???

What program and settings do you use, then?
Ok, I just purchased the 10.1. I use it alot to play back mp4 and m4v videos that have been encoded by Handbrake. What I've noticed on the 10.1 is that while they look excellent, when panning, the video pans with a jerky motion and is not smooth.
Any suggestions? I've looked around the forum but have not found anything definite. I've encoded the video at 720p.
From what i've read and researched, Tegra 2 only supports H.264 with Mainline Profile, Meaning 3 Reference Frames and no B frames, i've encoded several 720p Videos that way at 5Mbps and they play flawlessly.
While researching, i came across someone that came up with a Profile on Handbrake. That is what I've been using to encode my videos and so far, everything works great.
I will continue to do more Research.
Just a fyi, it does support High Profile, but with a max of 4 reference frames and 3 B frames.

Background
As I understand it, Tegra 2 should playback up to High Profile 720p and Main Profile 1080p. However, with limitation on Honeycomb and/or lack of driver release by Nvidia, current crop of HC tablets do not playback anything above Baseline Profile smoothly. Future updates by Google/Nvidia should fix this issue, but it looks like we may have to reencode High/Main profile media for the time being.

Even he says it, Tegra 2 currently doesn't support anything above Baseprofile because of driver limitations

I've only converted mkv files, but for 720p ones I use 1280 max output width, 20 video quality, live video type, high h.264 profile, and veryfast encode speed. For 1080p I just change the profile from high to baseline. All of my videos (with the exception of Avatar.....Man that's a long movie) are cut by two thirds. I guess I should mention though that I have a Motorola Xoom til I can sell it and get a Tab
If that doesn't work, just contact the OP of that post. He's really good at giving prompt replies.

how if we dont convert the file format ? is it possible to watch or is it laggy?
does the sound and the screen match?
Why would you do that?
The screen resolution is not even 1080 pixel height.
Don't you know that?
It's a waste of resources.
Try to get 720p instead.

Let me know what your research shows. I've been converting blu ray and mkv into 720p mp4 using DVD catalyst 4, real simple setup. From what I found out, mkv files do not work on any tablets because mkv is a container. If you convert it to mp4 then any tablet can handle it, including my phone galaxy s captivate . Takes me an average of 3-4 minutes per TV show and 10-20 on a movie. I stopped encoding at 1080p because there was not much difference other than size of file.
Sent from my GT-P7510 using XDA Premium App
they work but not with high profile settings. you need to reduce them.
you can google what high profile for mkv is.
The answers you are looking for: http://forum.xda-developers.com/showthread.php?t=1060825
mkv is not a format, its a container for H.264 format.
You should be asking "is it possible to play 1080p H.264 in the galaxy tab 10.1?"
The answer is yes BUT (and a BIG BUT) you can only do so if the H.264 file is encoded in the old H.264 baseline profile which nobody uses anymore.
Tegra 2s video accelerator is way to slow to play H.264 videos that are encoded in the popular Main/High profiles which everyone uses today. Yes its unfortunate but you have to recode all your videos to baseline profile if you want to watch on ANY tegra 2 based units.

The tab, along with every other Honeycomb 3.1, tegra 2 device plays H.264 high profile 720p and main profile 1080p video just fine.
Although given the screen resolution, playing back 1080p video of any profile is pointless.

Correct it CAN play them back but at only very low bitrate and 1080p is not pointless since you can hookup to TV or monitor via HDMI
I did some testing on bitrates for the Teg2 at 720p HP here,
http://forum.xda-developers.com/showpost.php?p=15054949&postcount=250
it does OK at 6Mb/s, and chugs when bits hit 10Mb/s. 6Mb/s avg is about the ceiling for most 720p videos, so one can generalize that the Teg2, at HC3.1, will play a fair number of 720 H264 HP videos (in MP4 format). Ruminations are that HC3.2 will speed things up a bit further.
The clip, along with others, are here if anyone wants to try them:
http://www.mediafire.com/?depxt4zyvpwel
I've played with h.264 video on the Gtab, Use Baseline profile for best results. I've done some encoding in High Profile, and baseline, and compared screen captures, and you can't tell the difference, it has mostly to do with Compression, the higher your Profile (Ref Frames, B Frames, CABAC) the smaller your video file will be without suffering Quality lose. Just that higher profile requires more horsepower to decode, which Tegra 2 does not have.

Honeycomb only supports Tegra 2 CPUs. HC 3.2 brings support for Qualcomm CPUs. I could only wish this thing had the SGSII CPU.
Yeah, much as I like my Tab, I always feel like I'm taking a step back when I use it after using my SGS2...both in speed and display. I'd queue up in the pouring rain for a week to get a SAMOLED tablet.

mkv is not a format, its a container for H.264 format.
Tegra 2s video accelerator is way to slow to play H.264 videos that are encoded in the popular Main/High profiles which everyone uses today. Yes its unfortunate but you have to recode all your videos to baseline profile if you want to watch on ANY tegra 2 based units.

Which explains why I am playing 720p24 high profile h.264 with no problems. Oh. Wait. No it doesn't.
Tegra 2 can handle high profile fine at 720p as long as you avoid wighted p frames. However the stock player does not. Enter diceplayer, built on the NDK and supporting all T2 decode capabilities. The stock player is totally borked.
1080p however is another problem. But you'll probably hit the fat32 4GB file size limit with those anyway before you encounter issues with high profile content. None of my 1080p MKVs will fit on the device anyway due to the fat32 limitation, so transcoding it pretty much a given. So I tend to go to 540p or even 480p just to save space. The screen is small, and while I can tell the diffeence between a clean 720p encode and 480p it doesn't bother me in this scenario. And if you drop down to 480p weighted p frames work again.
So, essentially Mr. Element, you don't what the hell you're talking about.

I can only support what ianken said. I can play 720p hig profile just fine with Diceplayer.
Here is a test clip to see on your own. http://www.multiupload.com/CJU6YB5JC3
It is in High 4.1 Format
just thought id let you know it does play 720p mkv files just fine (tested on my galaxy 7" with no skipping or slowness at all) assuming since it works on the 7" the 10" wouldnt have any issues with it.

Not entire true since manufacturers can add their own drivers to the OS
I highly doubt gingerbread is tailored to a single platform

I'm can play 720p high profile without any issues on Galaxy S Captivated. Gtab 10.1 and other HC tablets are using tegra2, that has some issues playing mkv high profile 720p. So far maker of diceplayer are the only one who have figured out how to make use of tegra2 to decode high profile 720p.
