Hello guys!
I've purchased recently a brand new x7510, mainly for navigation (love the display) and mobile office. I've installed the latest coreplayer 1.2.5 and loaded some vids that I used to show on my old good iPAQ 4700.
And.. surprise
the screen is green and there is no sound. I've played with the settings (changed video output from ati imageon to gdi) and now videos are running but way too slow. The builtin benchamark of coreplayer gives me different scores from 50 to 70%
What's wrong?
What settings are you using? Or maybe there's a better player around?

How about uploading one of the shorter videos for the rest to test and see who can play it most smoothly?

I have some flv files downloaded from youtube, but mainly videos of concerts recorded on my home computer from sat tv in wmv
One of those is about 30 minutes of Jewel concert:
Audio codec DMO WMA 44100hz 2 chanels/96kbit/s
Video codec DMO WMV (WMV9) 384 x 288, 1,15 Mb/s.
I think I've rocoded it for my mobile, but do not remember.
I just converted Superman Returns using Pocket DVD at the following settings:
IMAGE
Width: 464 pixels
Height: 288 pixels
AUDIO
Duration: 2:34:05
Bit Rate: 40 kbps
Audio Format: MPEG Layer-3
VIDEO
Frame Rate: 24 frames/second
Data Rate: 605 kbps
Video Sample Size: 24 bit
Video Compression: XVID
The only settings I changed from Core Player are:
1. Menu>Tools>Preferences>Video>Video Output>Direct Draw
2. Menu>Tools>Preferences>ATI IMAGEON>check Keep ATI Driver Active
3. Menu>Tools>Preferences>Buffering>Normal Buffer Size 700000
I also tried watching some You Tube Videos, randomly. No problems at all, except some anime looked crappy probably because they were not meant to be seen at such a big screen compared to other PPC.
I don't have any problems playing my converted DVDs. NO SKIPS, NO LAGS, NO DELAYED VOICE OR SOUND which I often see others complaining about. From my point of view, it is a matter of what converter and settings you used and what settings you have Core Player on.
So am I happy? HELL YEAH!!!!! It's better than watching using my Universal.
I don't know about the missing drivers that I often read others are asking. If Core Player can play my converted DVDs as good as my Universal, I don't see any problem with that. As I said, check your settings.
Nope still lags audio lag for me tried your settings...What version of coreplayer are you using? Did you use headphones when you played the video?

I just tried that video, when using core player 1.2.5 it almost runs fine, just that I don't have the ac3 audio codec. I also noticed a little tearing during scene change (fullscreen only).
My core player settings are:
Video output: DirectDraw
Video quality:High
Smooth Zoom: on
Dither: selected
Acceleration:not selected
DirectDraw settings:
overlay with colorkey:unselected
use blitting instead of overlay:selected
use device stretching for blitting: unselected (however I find that when I select this option with the one above I notice the tearing seems to go away but the video quality seems to go down a little)
I also increased buffersize:
normal buffer size:3392
preload at:70%
preload audio:64
Microdrive mode: selected
microdrive buffer size:56000
microdrive starts:1472
and thats what I have for coreplayer. Hopes this helps.
I'm going to try this vid in TCPMP and see how it handles it (I tend to get better video performance with TCPMP)
Another note, I have a x7501, however they're basically the same hardware.
I am using 1.2.5 version of Core Player.
I'm also using Coreplayer 1.25. Unfortunately I do not have the AC-3 codec. In any case, with rawframe buffer and set to highest video quality output, the picture is sensationally clear and fluid. I get 96.65% speed. Absolutely stunning and beautiful playback.
What audio plugin do you guys use for this video?
no problem playing videos properly coded for 640x480 sizes at max resolution, sound, etc
using TCPMP or CorePlayer, they both plays great!

But on which device, x7510? You mean you were able to install TCPMP on X7510?
Then which version? And could you provide your installer?

I have a x7501 no matter how I set it the video display is not smooth. I lovegbe big screen but when I made a video comparison with iPhone 3g, x7501 is worlds apart. iPhone 3g is so sharp and bright. I think it's a OS issue

Yes, and I commented that also. This version is no solution for me. It is not only to install the app, but to be able to play my videos as well.
This version gives me good audio and scrambled video, so no joy.
I have already CorePlayer and am happy with it, but just was curious.
hi
any news ?.....ways to improve?
I was looking for the best performance for CorePlayer on my 7510 and this configuration is best for me:
video:
selected driver - ATI Imageon (acceleration turned "off"!). Don't choose "DirectDraw", "Raw FrameBuffer" or "GDI" on HTC 7510 - they are slowest than Imageon without acceleration!
dithering - "on". halftones - "on". quality - "best"
Buffer: video output buffer set to: 4200 kb
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
Sent from my GT-P1000
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 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.

What are the specs on the videos that you are trying to play?
Here is a vid of me using Vital Player on the transformer with a H.264 encoded MP4 and an MKV movie. No lag, no sync issues.

If the movies you're trying to watch are encoded with High profile then playback will be laggy no matter what on the TF.

Nice!
Okay I'm a new when it comes ti all these video formats.. all I know is that I get choppy playback
So this handles 1080 but with some tweaks I'm assuming..again, I'm a new at this
Were those movies you converted? Is so you mind writing up a little tutorial
Thanks
For the MKV, I downloaded it was already encoded so I am not sure of its specs, but the playback quality and resolution are excellent even on my desktop's 24" HD monitors.
For the MP4 played at the beginning of the video, that was shot in 1920x1080, brought into Premiere CS5 for editing and exported through Adobe Media Encoder using H.264 at 1280x720.
There are some threads with Handbrake encoding specs on the forums as well.
When using Vital player make sure the Decode Mode settings are set to automatic. It will automatically recognize there is no hardware acceleration (as I understand is normal with the Tegra-2). It will then compensate with "software acceleration". Also in the Video Mode settings I have it set to speed over quality as the performance is better without sacrificing much of the quality to my eye.
With these settings, Vital Player should play just about any video you might download off of a torrent site. I have yet to find a video that does not play well through it. I'm not sure if other users who say it does not work for them have checked the Vital Player settings, if my videos are just not up to the elusive "high profile" they are talking about, or if I just have a rare Transformer that just works, but as you can see in the video it does work for me.

So you had to encode the mkv or mp4 before playback? So it cant just play them straight up?
Sent from my Transformer TF101 using XDA Premium App
I believe that nearly any video you get is going to need be encoded in some form at some time.
The MKV was more than likely encoded by someone else before I downloaded, but no further encoding was necessary on my end. The MP4 was shot on my own camera (Canon 7D recording at 1920x1080p) and needed to be edited. When you export directly from the timeline in Premiere, it must be encoded to even be usable. For sites like YouTube or Vimeo to even accept them there must be encoding. The H.264 encoding that I used is the highest setting for that type of video's purpose (HD web playback). It is different than what I would have exported for burning to Blu-Ray but is adequate for a screen the size and resolution of the Transformer's.
When I return home, I will try bringing in the raw, unedited video from the 7D (which is around 3GB for a 4 minute vid at that resolution btw) and see if Vital Player plays it back with no lag. I seriously doubt it as some average computers have a hard time playing that back without lag. Even Final Cut Pro can't import raw 7D video without a conversion (Adobe Premiere does not have this problem though). Why anyone would want to play a video of this size and resolution on a tablet is beyond me (3GB for 4mins is ridiculous in a playback form). I can't even imagine wanting to watch a full length movie in that form.
Both of these videos seriously choke in any player other than Vital Player (including Mobo, QQ, and MVideo). I couldn't play any video in my library with them or the stock player, but all of these files play just fine in Vital.
I'm playing 720p with no problem
converted with Handbreak. Settings below.
container: "mp4" everything else turned off
picture: "1280x720"
video: "h.264 (x264)"

I'm using moboplayer and downloaded some sort of codec pack (the player prompted me the first time and opened the app store). The default player also works.

Maybe that's all I was missing for the other players (I didn't get prompted to download codecs). I'll stick with Vital Player though simply because it's already on my tablet and it works.

90% of all HD videos you download the internet are ripped from blu-ray and likely encoded with high profile h264 because that's what looks best. the tegra 2 cannot handle these files at 720 or 1080p, and thus they need to be re-encoded to main profile, which as i understand it, means a much lower bitrate (and thus worse picture).

I got all excited because of this thread...but I just gave VitalPlayer a shot on a 720p high profile x264 and it still sucks. No artifacts but the framerate is really low it seems.
In case anyone is interested I did receive this message from ASUS:
"On this issue, we have tested some of the 1080p video is playing well. We have cooperation with google and will launch android 3.1 in June to resolve the 720p and 1080p video playback problems."
We'll see...

i believe that is flash only, as in 720/1080 youtube streaming which is much lower quality than a high profile blu-ray rip. the problem is tegra 2, which is a year old, not supporting 720/1080p playback. it's the reason boxee box dropped tegra for an intel chip.

Well I'm not sure if you know this but there are currently no accessories for MHL that can be utilized in the Sensation. Therefore, it can't be connected to a TV yet which explains why nobody is answering your question. Wait for the MHL dongle to come out and I'm sure people will start saying something.
trying to play 720p mkv just on the phone and its dropping alot of frames.
Tried QQ player and rockplayer but still not enough power to decode the movie in software.
May have to convert the file to mp4 to allow the hardware acceleration!
will try over the weekend and let you know
As of yet, nothing can play MKV's properly I don't think even the SGS II can.

I'll test this and get back to you later. I'm sure I've got a 1080p mkv somewhere on my PC.
I'm pretty sure the Sensation's software isn't optimized. I think when we see some custom ROMs (e.g. Android Revolution by mike1986) we may be able to play MKV's
I can play 720p and 1080p mp4 (h.264 High Profile at any bitrate + AAC) videos without any stuttering, using hardware acceleration.
MoboPlayer and DicePlayer can play 720p and 1080p MKV but with some little stuttering.

Thanks a lot for testing that out, much appreciated. A lot more useful than the guesstimates made by others in this thread.
My Sensation was unable to play a 720P 60fps H.264 8 Mbit MP4 perfectly smoothly in the stock Movies application. Playback on the SGS2 was noticeably smoother, even from a USB key. I will try it with Diceplayer... VPlayer was even worse though.
EDIT: Seems to playback reasonably well in Diceplayer, and perhaps a little bit smoother in Rockplayer. This could all be placebo though!

your test file is mp4. so rock or stock or any other player works same way.
(using embedded media player module)
if you test MKV/H.264-High/DTS or Flac encoded files, you can find differences.
MKV is just a container for MPEG-4 in most cases. I don't see your point.

point is mkv container is not recognised by the sensation default video player, so although the video stream should be played back via hardware decoding it is not.
Most other players that do recognise .mkv files use software decoding, which is fine for AVI (DivX/XviD) or low bitrate h264 files, but at higher bitrates the frames start droping.
Diceplayer is good because after it splits the MKV audio/video streams it recognises that the h264 video stream can be decoded via hardware, this allows much higher bitrates to be played smoother and should consume less battery as the cpu is not thrashing its nuts off.
It may be that in a future software update MKV are supported by the default player, as it is on the SGS2
I wonder if Android Revolution HD or CyanogenMod could play 1080p MKV with Diceplayer or similar, on the Sensation. Would be utterly fantastic if they could!
I'd like to see playback on an OC'd sensation/gs2
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.

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)
