I picked up the Tab yesterday after selling my Archos 70. To be honest the video processing onthe tab is poor. Speed wise iits great but the hardware decoder seems to not process the video correctly. This is apparent on 720p content, the image seems to be pixelated or downscaled very poorly, resulting in jagged image quality. It seems that lower resolution files such as 480p does not suffer from this problem. I have tried mp4 and mkv 720p files and the problem is still very noticable. After trying rockplayer xyplayer and a host of others i noticed that the image is far sharper under software decoding ( but too slow to be usable) , one hardware decoding is enabled the image becomes blocky.
To be honest the main reason for buying the tab was for the playback of 720p content on a good quality screen. ( archos 70 screen has poor contrast and viewing angles) , has anyone else noticed this poor hardware decoder issue? and is there any way around it? , I am running the latest firmware and feeling a bit dissapointed, my galaxy S has no such decoding issues.
Poor? It plays perfectly my test file, a 1080p trailer for the last Indiana Jones... And that beast reaches a bitrate of even 50mbps!

I have noticed the same thing.
Whit 720p movies the Tab do some thing to the image. Pixelated/downscale weird frames sometimes. When just watch on the Tab screen i dont noticed its so much. But when i connect it to the hdmi dock and run the move on big screen its gets really noticeable.
And its like you say, on low res movies its looks good like youtube or other movies.
But whit 720p its looks weird some time whit lost frames or what you can call it.
Can't explain it whit my poor English.
The Tab play all my movies just fine. No lagg or so. Its just like the above described. Its seems it have problems to decode or handle the image the way it should look like.
And i use the stock Samsung player.
Think the Tab has same problem when you look at pictures in the gallery. Its downscale/mess up the image. Have read about that here on Xda

It doesn't happened to me when I play with Samsung Video 720 & 1080p.
I don't trust RockPlayer.
FYI.
No issues here either, 1080P and 720P all played fine... best file format seems to be XviD..

I agree. The Tab plays my ripped blu-ray movies beautifully. I keep resolution at 1080 too. No lag or picture quality issues.

I use the the standard video player and it works fine, rockplayer lagged and put movies out of sync for me
Use stock player instead, never really trust rockplayer
cannot play any 720p mkv at all. Stock/Rock player. I can play 720p MP4, but audio does not work : (
no problems using 720p movies with standard video player

I think your problem is that there is DTS / Multi channel audio in your movies.
The Galaxy Tab can't play Movies whit 5.1 audio. It haves to be stereo sound or it won't play.
It's kind of sucks, because almost every 720p movie haves multi channel audio that SGT can't handle.
Little annoying that movies have to be converted only for the audio.
What i do is that i convert my movies whit Formatfactory.

Is this phone powerful enough to play Full HD videos? 1080p?
If it is, could you play smoothly YouTube 1080p rips? High bit rate .mkv files?
And what player you use for full HD playback?
dont think it will... altough i can play 720p mkv very smoothly with Diceplayer !! did test a couple 1080p which wasnt that smooth....altough i heard that converting into .mp4 results into much better playback because of native support
Of course it can play 1080p videos.
Using the standard Gallery, it can play the 1080p videos that the camcorder records, and it can (so far) play any 1080p MP4 video that I put on the SD-Card or stream from my media server.
There will be some file formats that it won't play, of course, but that's a problem with the format rather than the resolution.
It will also play 1080p MP4 videos through my Sony Bravia TV via DLNA.
abuserkadayf, sjgore, thank you.
sjgore, I see you got HTC Desire too. And it have trouble playing some 720p mkv, never been able to make it play any 1080p. MoboPlayer is the best all around player from point of format support, speed and UI. But there is like a dozen players that based on FFmpeg library around(VPlayer, QQplayer, VitalPlayer, RockPlayer etc...). Was wondering if new generation of hardware is able to support 1080p to the point that there is no need to **** mind about how fast particular video player and choose one solely based on convenience of use and price...
Never tried 1080p on my Desire. 720p was fine, including 720p videos taken using the camcorder in CM6 (720p wasn't in CM7 for some reason).
I haven't even tried any 3rd party players from the Market on the Sensation yet, everything so far has been achieved with what comes built into the phone (ie. just Gallery).

Camcorder 720p clip are H.264 720p Baseline. 1st gen. snapdradon ( QSD8260 ) can play 720p Baseline profile.
but most of 720p/1080p movies are H.264 High profile level 3~5.
If file format is MP4(H.264+AAC), stock player can play .
Many of HD movies are MKV/AVI format and audio codec is AC-3(5.1ch) or DTS or Flac.
ffmpeg base player can not play HD ( 720p/1080p ). Decoding & rendering need too much CPU power.
If you want to play HD(with DTS/AC-3/FLAC + MKV/AVI) clips, use diceplayer.
In particular MKV files.
I have noted that if I playback an 720p MKV with AC3/DTS sound the video plays perfectly fluid. No microjudder or frame drops AFAIK. But there is no sound of course because the inbuilt player does not support AC3/DTS natively.
However add AAC 2.0 audio into the file (MKV or MP4 container it matters not) I see judder. Kinda like when you have 23.976FPS playing on a 50Hz PAL CRT.
I have tried muxing at various framerates and interestingly the judder gets faster the higher the FPS. Very odd.
I'm used to dealing with AV stuff as I use MPC-HC/ReClock/MadVR etc to my HDTV over HDMI (BTW my Panasonic G20 Plasma does not recognise the TF HDMI output. My PC monittor does however so the TF is outputting in an unsupported res/Hz for my HDTV obviously).
It's puzzling me how when the TF does not have to playback audio the video is perfect but as soon as it has to decode audio it throws a wobbly.
The other interesting thing of note is that Youtube vids at 720p and even 1080p (Big Buck Bunny for instance) play just fine. Methinks that Flash is optimized to the Tegra 2 chip whilst the inbuilt TF player (and all the other players) are not. Moboplayer, Vplayer etc are all a bit crap at it. There is one player called LittlePlayer which gives the option of hardware playback but it is no better than the inbuilt player as it does not decode AC3/DTS and it too judders when AAC audio is played.
Anyone got a clue why this is the case? I was wondering if it was a UK specific issue (would not put it past Asus to make it PAL centric) but then why would it play a 23.976FPS 720p x264 in MKV perfectly (sans audio obviously)?
Yeah I have a 720p mkv and it plays a little off with the sound but I play a higher quality move still at 720p and the sound is like a second off. And the 1080p vids I have don't play at all. What app do you use to play your videos?
Sent from my Transformer TF101 using XDA Premium App
you must be doing something wrong with the muxing or the avc stream you ended up with is not extracted properly.
I encode movies with x264 (commandline), encode the audio with neroaacen(lc, cbr, 128kbit) and mux them with mp4box. The file plays perfectly with the built-in player, meridian or rockplayer in hardware decoding mode.
Most mkv TV series I can extract th evideo stream from and use it, but not all. Some use too many reference frames while encoding and the TF can't handle it.
X264 profile high, level 4.1, preset veryfast or medium. No other options except quality level ((crf 20 or 21 I use mostly).
I've tried MKVToolnix for straight muxing. A simple MKV to MP4 prog without reencoding called mkvavi2mp4. Handbrake (Used settings suggested on this forum). I've also tried some test clips from various sites. All of them judder when audio is being decoded. I am not talking about HUGE judder. I am talking about very small judder. The video is not 100% fluid. Some may not even notice it. I do because I am always messing with progs like ReClock and MadVR in order to get perfect 24p playback to an HDTV. I am also susceptible to phosphor lag, any audio sync issues and other annoyances. I am Mr Super Anal when it comes to perfect playback and have color calibrated all my displays with a colorimeter
But I digress.
If I play Big Buck Bunny 1080p in Youtube or in the default browser it plays fluid (well enough not to be annoying). Now if I rip that same Youtube clip down to my hard disk. Copy it to the TF and play it in ANY player (Moboplayer - with or without codecs packs, Rockplayer, Vplayer, Littleplayer or the inbuilt player) it will not play it without stuttering. What the hell is that all about? Flash player is better at video playback on the TF than Honeycombs implementation? Quite.
I wish I could figure out a way to load the MP4 files in Flash through the browser. I tried file://path to MP4 and it did not work.
If anyone knows a way to do that I would be interested. Maybe I should setup a web server on my PC and stream everything in Flash
P.S. If you wish I can provide you with two sample MKV's. One with audio the other without and you can directly compare the two and post your results. I see small juddering on the clip with audio muxed in every time.
The Youtube app is not using Flash. If it was, Youtube wouldn't play on the iPhone or iPad, and it most certainly wouldn't have played on Android devices before Android 2.2. If you want to see true Flash performance so far, load up Hulu and see if you can get a 480p stream to play acceptably. Edit: Since you mention the UK though, I probably shouldn't assume you're in the US. If that's the case, just load up any Flash-based video player besides Youtube. Sometimes it helps to set your user agent to Desktop, too.
The Youtube app is actually using HTML5, with videos encoded in H.264/MPEG-4 AVC and stereo AAC. The maximum bitrates supported are 5 Mbit/s and 152 kbps, respectively. You need to bear in mind too that by playing videos through the browser, the servers will recognize the device you're playing from and compress and optimize the stream accordingly. A full 1080p video at 5 Mbit/s would take forever to buffer on a tablet, so it's highly unlikely that you're getting the full quality over the network stream. Locally-stored videos, however, are free to be downloaded and played in their maximum quality, so it's understandable that you may see some stutter on large files.

Check the panning of each. One has AAC audio the other not. Use the default inbuilt video player of the TF (Should offer if you click on the files if you have other players installed). The one without audio plays perfectly smooth on my TF. The one with audio has slight juddering.

Just to clarify: You are talking about viewing youtube via the default _web_ browser, setting your user agent such that you get the desktop site and using the flash plugin to play the video? Rather then using the mobile youtube web site or using the built in youtube app?
FYI of your two clips the one without audio plays smoothly in the _default_ player and the one with audio chokes with "This video cannot be played" (This is assuming you tack ".mp4" onto the file names to fool the default media player into trying to play it)
Interesting... I just re-encoded the audio _only_ ("-vcodec copy -acodec libmp3lame" in ffmpeg) and that plays smoothly.
Now mp3 audio isn't part of the mp4 container spec so you'll only get away with it in an mkv container (its flexibility is one of the things that makes matroska difficult to parse)
Ah... the video is High profile at 3.8Mbps that pretty much on the limit of what the tegra2 can do at the moment (I'd say it over it actually) so I'd say that the addition of a complex (relative to mp3) audio track is just too much.
I bet if you re-encoded that video to baseline at the same bitrate and copied the audio stream it would play fine, its just at the max computation threshold.
sub'd... I want to see what you guys are doing, I'd really like to play at least 720p peacefully.
I've tried reencoding using Handbrake and get similar results. Jerky playback with audio. Smooth without. It's like small juddering every quarter second or so. Ignore the web playback that's already been explained that it's HTML5 and is not sending me the full 1080p stream anyhow.
In fact. If someone can send me a 720p video clip with audio that they say plays 100% smooth on their TF I could see if it's not 100% smooth here. If not (as I suspect it won't be) then it's either my TF has issues. Your eyesight is not picking it up or I am going nuts

I am using the same profile settings in handbrake (high profile) and ALL my videos are really smooth! and YES...I did have judder/stutter before. download the sample files and you can test it on your TF.
the ONLY downside is that handbrake takes a while to encode but its worth it!
hope this helps.
..........
While I agree that, officially, Honeycomb doesn't support the mkv container. It must be able to parse it as it does support WebM and that uses the matroska container.
http://dl.dropbox.com/u/6553908/with_audio_mp3.mkv
This is the same video stream but with the audio re-encoded to mp3, plays nicely for me in the default video player it I tack ".mp4" on the end to fool the player into trying to play it.
I don't stream but everything e.mote said about hinting is spot on, also you may want to look at interleaving (a feature of the muxing that MP4Box can do) is you want to stream.

Way too generalized. I have a Playbook and it plays 1080p Youtube in the browser flawlessly.
I played The Cape clip from the example Handbrake settings thread. The clip plays with micro judder like every other clip with sound. I am now using a Prime 1.4 rooted not the stock firmware and it still does it. It is like frame drop every half or quarter second. If you have ever seen NTSC 23.976FPS played back on a PAL 50Hz CRT TV you will know what it looks like. It is very obvious on pans.
Surely I cannot be the ONLY person who can see this??? Are your eyes really that bad?
EDIT: Tried the MP3 version you provided. Still there. You can count the judder. Tick tick tick tick... every quarter second.
EDIT2: I guess the only way to demonstrate this to you guys is by way of a video of it along with some audio prompting from me to point it out to you (excuse the d(t)icks). You will notice that the audio drops out for some reason during playback but when it does the video plays buttery smooth. No idea why the audio drops out. I was playing back the MP3 muxed version from the link above using Moboplayer but this problem - the juddering - occurs with any player I have tried. The juddering happens on every single video I have tested it on when it is decoding audio.

I will restate however. Yotube playback looks much smoother than playing a file from the inbuilt flash memory or SD cards.
I am having the same problem as you and I see the judder on these clips as well. I posted my issues in the encoding guide thread:
http://forum.xda-developers.com/showthread.php?t=1060825&page=9
It has nothing to do with the overall bitrate rate as many of my samples are <2,000 kbps, and just like you, if I remove the AAC audio, video is silky smooth. I assume it's just a software issue that should be able to be resolved, but I guess we'll see...
e.mote said:
BTW, if you recoded the clip, then I suggest using better settings. The settings used are excessive. When facing a device with marginal playback, there is less tolerance for bad encodes. If you're anal about playback, then you should be equally anal about your encode settings.

Thanks for that. But since your video judders just like every other clip that means diddly squat. I don't see why I should have to reencode every video I have in order for it to playback on the TF either. It should be able to handle 720p at least. It does play it but only plays it smoothly with no audio playback whatsoever.

Phew! Thanks for chimeing in! I am glad it's not just me. Do you live in the UK perchance? If not that would rule out any UK specific reasons.
Nope, I'm in the US. My TF is also running Prime 1.4. I've tried the "stock" kernel and the OC kernel and the problem is the same with both. I didn't think to test video before rooting and installing Prime, so I can't vouch for whether or not it happens on completely stock HC 3.1

Are you serious? I see literally no issue. Either my eyes or your camera, one of the two can't pick up this judder. And I did notice the compression in the better encode offered here (text, grappling hooks, lasers, pretty much anything like that. Not a bad result, but clearly visible)

Not that I would really notice any difference between 720p and 1080p but I think there might be some misunderstanding that the TF can play back full 1080p video (1920x1080). Or at least mine can't without encountering serious lag.
I can't play 1080p on the browser YouTube without lag. Also the YouTube app doesn't let you chose between 720p and 1080p so I'm guessing it only plays 720p. to make sure it wasn't a browser problem i download a full HD video (www[dot]digital-digest[dot]com/movies/Limitless_1080p_Theatrical_Trailer[dot]html) and as expected it played with a lot of lag. Can anyone else check on that too?
Thanks
Wondering the same, I hope there is a solution for this problem, Otherwise it may be false marketing/advertisement which would be very sad fact for us as TF users indeed.
So I tried searching for an official quote stating that the TF can playback 1080p video and the closest i came was this line from ASUS's website-
"A 5MP rear- and 1.2MP front-facing camera can shoot and record HD video, which can be played back in stunning 1080p."
Even here it doesn't state clearly where exactly the video can be played back. Nowhere else does it mention that the TF can playback 1080p. I think it's just clever marketing on their part but it does lead to general misinformation about the product.
Why would you want to play 1080p content if the screen only can handle 720p anyway?

Hdmi out to a tv is what comes to mind.
The transformer will do 1080p resolution out to a TV or monitor, but I do not think it is capable of playing true HD videos such as the Limitless trailer you listed.
Mine does play youtube in HD very clearly with no lag.
but I have put a HiDef MP4 video on here and attempted to play it and it was choppy or didnt play correctly at all.
I recommend AVI files and Vplayer or using a program to change the bit rate of the hi def files and trying to play them again.
Yes it will play 1080p, but it will only play 1080p low profile and only with minimal bitrates. I have made several for testing that play fine using Handbrake, but in reality 1080p over HDMI is a bit flawed at the moment, and the tablet doesn't show native 1080p so since you have to re-encode blu-rays anyway you're better off with a high profile high bitrate 720p conversion than low end 1080p.
I have not tried any of this with 3.2 yet.
While we are on the subject, does 5.1/7.1 also work via HDMI?

1080p will not play (atleast my encodes), while 720p seems to play just fine. I'd stick with 720p personally. I don't use the HDMI out, but I can see a reason for having it, it'd be nice.
I've played 1080p videos on youtube with no problem. I'm rooted and running revolver v1.1.3 (HC3.1) at 1.5 GHz.
Playing Youtube videos is not a good guideline really. Unless you make sure you are using a browser with the user agent set to Desktop and also that your Youtube settings are not set to HTML5. Then manually setting the video to 1080p and testing.
The very first bulleted item at the official ASUS product page previously stated "NVIDIA® Tegra™ 2 1.0GHz dual-core CPU for excellent multitasking & 1080P video playback" but now it states "NVIDIA® Tegra™ 2 1.0GHz dual-core CPU for excellent multitasking & HD video playback". I guess they finally decided to change it. I knew I should have taken a screenshot to prove it back when I saw it.
Hello,
I have purchased a second hand T95Z plus, but have been experiencing issues with FullHD videos playback. Everything that is above 7Mbps is lagging. Tried different players - VLC, PlayerXtreme, the integrated video player. Tried with Wifi as well as with ethernet connection. Every time I play a decent FullHD quality video, it starts lagging. Just to confirm, this is not only for streams, but for videos stored internally and on a network share.
Obviously the issue is not with the connectivity, but with the video playback. The box itself is advertised as "easily" able to stream 4K videos, so I am afraid that it might have some hardware issues as 1080p videos with >7Mbps bitrate is lagging.
There might be overheating or some other related issues, but I am fairly new to this, thus am seeking help from other people with more experience with this device. If there is someone that is able to help me narrow down the main cause of this, I would be really thankful.
Here are details:
Android 7.1.2
Build: T5ZPE1081
BTW, when I start some 4K UHD video in Youtube it is playing it just fine. So maybe the issue is with the encoding or the video players that I use? Cause the 4K Youtube video is showing bitrate between 15 and 30Mbps.
