Question about watching movies on the xoom

of the reviews i read, a lot of them said that video support was hit or miss, presumably on the stock video player. on my phone i use rockplayer, it can play everything i throw at it, without having to encode.
is rockplayer in the tablet market or can you sideload it?
if so, does it scale properly, and can it play most anything?

I played a few AVI's with no issue. Haven't tested mp4's, though I think the native player handles those.

Downloaded fine for me, was really choppy so I enabled hardware decoding in the settings of rockplayer which made the video extremely smooth but the audio didn't work. I know it works fine on my computer in vlc. it was 720p MKV, high quality encode. That was all I tried, it didn't play the avi. Though I played an avi in another program and it played fine. But I assume since Rockplayer was able to play the video fine with hardware decoding enabled it should work good, not sure why the audio didn't work... could have just that one mkv but thats all I have tried.

laaaavely.
i don't have too many mkvs, mostly avis, so yay.

The only thing I don't like is the inability to play high profile h.264 video and all my video is high profile.
There is no reason Tegra 2 shouldn't be able to play videos that my 3rd gen iPod Touch can handle without breaking a sweat.

I read all the comments about the bad quality, and them tried AVI on rocketplayer and it looks amazing. the only problem I'm running into is the volume not being able to change.

I am not having any issues really playing movies with either the native player or Rockplayer. Though, most of mine are MP4 files.
If you bump into file type issues where you have one kind that works great, but another that does not I would recommend Tunebite. It can take any video and make anything out of it... as long as your PC can play it, it can convert it. DRM junk included.
I used to have an iPhone (hangs head in shame) and had taken a few movies from Blu Rays download copy thing and put them into iTunes (hangs head again in shame). When I went to Android (stands ups proudly) I needed to bring them over. So, Tunebite to the rescue.

If you can't play a video on the Xoom, follow these instructions. Has worked 100% of the time for me using the Xoom stock player:
http://www.gigadroid.com/androidtalk/viewtopic.php?f=14&t=21

Well yeah that's transcoding the videos. Of course that works - it lowers the bit rate and takes hours to do. Its really sad that a 2 core CPU and a 8 corr gpu can't decode high profile 720p video. I can't get the zoom to play anything my Streak can't. Pretty sad and disappointed now. Some how the notion ink adam can though.

[Q] Chances for better hardware-accelerated media playing?

Hi Iconia-Lovers,
I really love my Tab for web-browsing and gaming, but you have to admit it sucks at video playing. MP4 and 3GP are crappy formats that are hardly used in RL und converting your whole video and movie collection isn't a real option.
I had have an Archos A70 which plays even 1080p MKV flawless with a single core 1GHZ CPU, but relies on an additional decoding chip if i get this right.
In theory, the Tegra 2 has more than enough power to play 1080p files, right?
I already tried like 6 different media players but all of them weren't able to play 720p mkvs nice and even non-HD-avi-files felt a little slowed-down.
So can we hope for a hardware-accelerated media player that enables alle the joy of moving pictures for us? Will possibly acer itself help us out on this issue? What are Samsung and Motorola doing on their Gingerbread tablets to enable nice media playing?
Hoping for a better tomorrow
Cheers

you sure about that?? my 101 throws a fit with 1080p mkv videos and both use the the firmware.
but i agree, i would love better video support on the iconia, since it runs circles around my archos when it comes to everything else.

Tried VPlayer? it costs like $4/ £2.30 but it can play practically all standards, not sure how it fares for 1080p tho.
I had it playing .avi and .mkv fine though.
Vplayer--
Video formats: divx/xvid, wmv, m4v, flv, rmvb, avi, mkv, mov, mp4, 3gp, ts, tp...
Streaming: http, rtsp, mms and m3u(apple http stream, m3u8)

I use UPnPlay (network streaming) along with MoboPlayer and it has played everything i have on my NAS very well.

Also I know Rockplayer gives you the option of hardware/software decoding so you may want to give that a try if you haven't already. There is a free version.

Both moboplayer and rock player are useless for my 720p and 1080p videos... total stutterfest, but that's a known thing for tegra devices on 3.0...

Hmmm... I use moboplayer, and every 720 did I've tried has been great! I haven't tried any 1080p vids though.

tested 1080 quality....the videos lag and the audio missing....
hope acer will figure it out....

Avatar & 10,000 B.C. in 1080P using UPnPlay & MoboPlayer streamed from my WD NAS, looks great. No lagging at all.

I have been trying all the suggested encoders to get smooth playback for film material as 60/50hz works fine. I maybe more sensative to it than others as I tent to look for it on moving objects. But I got it to replace a media player too.
I tried the script posted in another thread with good results but the jump is still there.
Bought DVD Catalist 4 with same results.
Freemake with custom profile same again.
Handbreak I find too slow but I read it works but can't verify it.
Any Video Converter Pro with xoom profile WORKS - it has very little judder but having to strip the subtitles out of the MKV every time is a real pain ( Anyone know how to disable them ) and it's too expensive anyway.
Trying to edit DVD Catalist 4 profile now but no success yet
Oh and I tried Vplayer , Rockplayer , Moboplayer and any others I could find
Hope my two weeks at this helps somone else out.

@RaveOn911
With any problem, you need to find its parameters. Only a handful of people notice the "micro-stutter" deal, so it's either a user sensitivity issue, or a tablet-centric issue (which could be hardware or software, user-caused or device defect).
Ask somebody to watch a video clip on your tablet, and ask them if they see anything wrong with playback. Don't tell him beforehand about "micro-stutter", as you don't want to bias his observation.
If he notices the stutter, it's your tablet. If he doesn't, it's you.
If the first, then bring a video clip on a uSD card into a store and try it on other tablets (hopefully with same or similar make as yours). If it doesn't happen on other tabs, then replace your tab. If it happens on every other tab, then again it's you.
If you have heightened sensitivity, then there may be params that can alleviate the issue. The default interleave for MP4Box is 0.5s. You can reduce this interleave, eg
MP4Box -inter 250 -add infile.mp4 -new outfile.mp4
(or)
MP4Box -tight -add infile.mp4 -new outfile.mp4
MP4Box works on MP4 only. Given that MKVs can only play in software mode currently on Teg2 tabs, it's a fool's errand to play MKV and claim that they don't play smoothly. Avail of the native support.

Mobo Player plays my mkv and xvid/divx AVI's just fine. I'm no codec/encoding expert, but from what I've read it's worth re-encoding some of the files to a more manageable bitrate for both audio and video and maybe dump the 5.1 or AC3 audio. I haven't looked at every file I've played, but a couple that would choke on my Win7 Asus netbook, I re-encoded with Handbrake. They still look and sound great.

I understood that that's the whole point the OP was trying to make: he wishes that someone makes a video player application that can handle MKVs via the hardware decoder. It's not a bad thing to wish for, either; it would provide better performance and hardware playback uses less battery, too.
The question remains: is it possible? As far as I know, the chip itself doesn't get relayed anything more than the actual video stream inside the file, regardless of the container, and thus an app should be able to do exactly that. But since I don't know anything about Android internals are applications given any such access?
My N900 phone uses regular GStreamer stack and thus you can demux anything you want and supply the video stream to the hardware decoder. As long as it's H.264 normal profile and not too high a resolution it'll play, regardless of the originating container.

There's nothing wrong with wishing, but until it happens, we have to use what we've got. For HC, for now that means MP4 for native support.
3.1 thus far has been worse than 2.x insofar as multimedia, probably because vendors have had 2.x for much longer, and were able to add enhanced support. A good case in point is the Samsung GalTab 7 vs the GalTab 10.1. The 7, released last year, can play MKV. The new 10.1 can't. Ditto for all the "my old phone can play MKV, why can't my tablet" complaints. It is what it is.
From all indications, HC was and is a rush job. It had to be pushed out the door because of competition from the iPad. I think the prospective buyer should understand that s/he is buying into a beta, and temper his expectations accordingly. Android has high potential, but now isn't then.
I've written a script that does fast remux/convert to MP4. A straight remux takes a few minutes, and it can process batch. It's a more productive route than wishing for a HW-accel player to come along.

I suppose that's a matter of viewpoint.
I took a look at the MediaPlayer class in Google's APIs and it seems to me that it should be fairly straightforward to demux the MKV file in software on-the-fly, create named pipe with mkfifo and feed the MediaPlayer class the raw video stream via that. Just throw a simple GUI on top of that and you have a rudimentary video player capable of playing MKV files with hardware accelerated video.
I'll try it out once I receive my tablet, was planning to learn Android programming anyways.
PS. Bah, doesn't allow me to post links yet :/

Does this tablet do MKV natively?

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.
Regards,
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.
(Stock player and Vplayer on 3.1)

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".

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

TouchWiz removed video support?

One of my favourite things about the Tab 10.1 is video format support. My #1 use for the device is watching videos during my morning/afternoon commutes. I download some videos the night before, and drop them onto the SD card in the AM. The Tab was able to play all of the formats I threw at it in 720p no problem, in the stock video player.
The first thing I noticed when I turned on my TouchWiz-updated tablet this morning is that none of the videos on it work. They show up as thumbnails in the gallery and video player, but cannot be played. In Moboplayer, the 720p files struggle because it's now relying on software decoding.
Is anyone having different experiences, or have a work around? I really hope this is not an intended change, or I'm probably going to return it. Too bad as I otherwise really like the update!

The update broke 720p high profile support. 720p baseline still works fine and the difference in image quality is negligible imo.
I hope they fix it in the near future, but as it stands now you either take the improved browser in this TW update, or go back to stock 3.1 or one of the older TW leaks and get 720p high profile support.

That sucks! I am assuming it is a bug and they will fix it.
I apologize for the upcoming noobish question as I'm not particularly familiar with codec's, and don't know the different between baseline and high profiles. I'm assuming I can convert one to the other in one step with handbrake? And would the difference in size be substantial?

Yep use handbrake and the baseline profile attached to this post: http://forum.xda-developers.com/showthread.php?t=1060825
Just queue up your files and walk away. I think the files might end up slightly larger but I'm not 100% sure, either way it isn't a big difference.
I'm also assuming it's a bug as high profile playback was a feature that was added in HC 3.1

Can anyone comment on DivX/AVI support?
I picked up my GT10.1 today, and since it supports DivX out of the box, gave some a try. I was disappointed that the picture broke up and pixelated repeatedly on every AVI I tried. So, I installed Mobo Player and tried it in software mode, but got exactly the same results (which surprised me somewhat).
I also have an Asus Transformer, and those AVIs play flawlessly on the TF using Mobo Player in software mode (since Asus didn't add hardware support for DivX).
I'm wondering if this is related somehow to this issue, since my GT10.1 came with Touchwiz.

Dave

720p High Profile H264 is indeed broken. Verified in Mobo Player and System Media Player.
How do I know they are high profile? I made them, and because I only encode in high profile via handbrake.
Bummer because the Tegra2 handles 720p High Profile H264 wonderfully prior to this update.

I have 4 video players loaded because the built in video player couldn't play all of the videos that I have loaded. Ironically I have the exact opposite experience of the OP, it now plays all the formats I have loaded.

This is extremely disappointing news because one of the things I love about the SGT is the quality of its video playback. My friend has a Xoom and he was blown away when I showed him some hi-def videos I downloaded.
I have a lot of high-def videos I downloaded straight from Vimeo, and they play flawlessly on my SGT without any conversions whatsoever. The thought of having to use Handbrake -- or anything else -- to convert every video I own is not very appealing to me. I hope Samsung fixes this problem.

I have mVideoPlayer, which I like the best. I also have ES Video Player which comes with the ES File Explorer. And, I also have VPlayer.
VPlayer will play anything I throw at it. I've never had it not play a video. I only downloaded it because it's required by Remote Potato. Remote Potato lets me play Recorded TV from my Windows Media Center cable card tuner.

To be honest, this is sort of souring the update for me. I'll be testing when I get home to confirm there is no problem playing back lower resolution files. Still, I like to keep a few high-def movies on my Tab and don't want to convert them all. I hope this is a very temporary problem, not something that gets fixed for the 3.2 build.

I don't know if this is related, but when I was trying out the new Kies app on my PC with my tab connected over Wifi, it (Kies on the PC) offered to download new codecs when I first tried to transfer a video over to the Tab. My PC shouldn't have needed new codecs since all the video play on my PC.

Full HD playback working for me!

Just thought I'd post this here in general too, since people tend not to check the "Themes and Apps" section. In short, full HD (1920x1080) is working great on my tablet with the latest BS player lite. It played a .mov fine, a .mkv said that HW decoding isn't supported and that's where I stopped, since I don't have full HD videos in any other format.
Link to the thread in the other section: http://forum.xda-developers.com/showthread.php?p=20657377#post20657377.
Tried 5 different videos now, all were working steadily at 20-28fps (over LAN play).
Can anyone else test it on his tablet?

Thanks for the info, I dont have any of my video in MOV format so i tried some of my other files.
It struggles to play 720p x264 files in both MKV container and MP4
1080p .... Unwatchable.
At the moment it seems dice player is the best option, it handles 720p x264 avc4.1 mkv pretty well, which is the format most people would use to store their bluray media.

The Galaxy Tab 10.1 comes with 1280x800 resolution, so although you may have your videos playing, they are not playing at BlueRay HD quality.
You can save some storage room by downsizing them.

Yeah I know, I was just excited about it, because sometimes, even 720p videos struggled hard ... Seems my excitement was a bit unjustified, as it seems it was only a few files that can play smoothly at 1080p, and they were probably able to play nicely before the BS Player update too.

Most of the 720p mkv files i have tried either have audio a little out of sync or it becomes choppy when there is fast movement in video. Do you guys think files like this will play better when ICS comes out? or must we get a tegra 3 tablet to enjoy 720p mkv?

If you're not the one encoding the videos then you aren't in control over playback quality on your devices. The tegra 2 has limitations on what encoding settings are supported for h.264 and these have been discussed in various threads. For those who want to play files over their networks without having to redo their rips it sucks big time. What I do is just run plex media server on my htpc for videos I may want to watch occasionally and I'll rip things I want to carry using the proper setting specific to my tab.
