Hello Guys,
I have used both Vegant and Latest TNT 2.2 and both lag while I play 720P .mp4 encoded videos downloaded from youTube, I'd like to know if its a software or hardware limitation? Does anyone else have the same problem with 720 .mp4 files from youtube? Does it lag (as in audio and video lose sync - audio plays faster than video).
ive incoded some 1080p bluerays using handbrake normal preset H.264. container mp4 also had to do this with 1080p .mkv files couldn't even get them to play otherwise. after that they played great on my tablet
The Tegra 2 chipset cannot handle h264 encoded as high profile. Main profile works fine. I know this confuses some people, but grab the excellent "mediainfo" tool (http://mediainfo.sourceforge.net/en) and you can see how your file is encoded.
MP4 containers seem to work best, although I believe Rockplayer can play MKV's with hardware acceleration.
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?

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.

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.
http://www.youtube.com/watch?v=oXfdQP8BtEA
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

How... what...
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)

can the tf 101 play back HD videos in 720p or 1080p with good performance? so far ive treid .mkv, .wmv and .mp4 108ßp files but all of them were way too slow or didnt play at all - is there something one has to do in orderto play HD movies, or is the tf101 too weak?
I've played 720p MKV's and MPEGs with reasonable performance on the stock ROM, but whenever i try to play anything 1080p the wheels start coming off. AFAIK b/c the transformer doesn't have a 1080p screen it won't be able to play 1080p videos (or if it can, it has to downsize them) and that's why it goes haywire whenever i try
In my own experience, I've found that using .avi format encoded with h246 codec (I use TVC) works surprisingly well. I've only converted 720p vids and they run damn smooth. Haven't tried 1080p. Don't need to really. More pixels and I think my eyes might bleed.
Hope that helps. Except the bleeding eyes part.
720p (either mkv, avi or mp4) works okay when using player capable of HW decoding, like MX or Dice Player. I'm not sure about 1080p, but i doubt it would work with acceptable performance.

Ah yes! Very true. Be sure to go to the Market and download "Mobiplayer" and all its codecs. That's your best video player for the tablet right there. That's what I use to play my files. TF definitely can play these resolutions, but it depends on the format, like on any device.
Rumor is that 1080p Main/Low profile works with HW decoding, but not the High profiles.
Mx video player or dice works well. Some mkvs play better on dice and vice versa

Hey folks, I was trying to watch a video on my TF101 that I made with my Galaxy S II today, it's a 1920x1080 17Mbit/sec h264 video file. MX player won't play it in hardware. Any way to fix that?
Try Dice Player with the tegra plugin.
Freemake Video Convertor
Easiest converter I've used....take your 1080p file select 720p mkv or what ever other extension and press convert. Might look into the audio settings a bit more tho. (I haven't yet) but the audio comes out not as loud...
Then use MX video...with HW video and SW audio.
Also this might save you time if you try the converter...don't use the Android setting...didn't work for me...wasted 4 hours (slow laptop).
Swyped using my Pinky
I really didn't want to have to transcode the video.
Diceplayer didn't work, even with the plugin. It was a stuttery, frame dropping mess. At least in MX, it plays in super slow motion.
For me, BS Player seems to be the best for playing HD mkv files.
It's not an MKV file. It's h264 in an MP4 container recorded by my Galaxy S II phone.
Did you try playing it in S/W mode? I've had to use it for 1280x720 videos on my TF101 and Captivate with MX.

Argh, sorry. I really suck at multitasking.
I was just transfering a mkv file over to my Transformer when I wrote that comment. lol
What I meant to say was that BS Player seems best for me to play HD movies (with big file size).
