I have the same problem with Windows Media play WMV's, the longer i watch the vid the more out of sync it seems to gets, normally the audio comes after the video, and the time just keeps increasing. then when i press pause. the video stops instantly and the audio carries on until it catches up.
However, if i plug the advantage in to the power surpply it doesn't seem to be as bad. It makes me think that it is due to the CPU speed, mentioned in http://forum.xda-developers.com/showthread.php?t=305214
But if anyone has any ideas about how to keep it in sync it would be appricated.

ive tried it with the power cable plugged in. still losing sync. just stopping and starting it corrects sync problem. i have now tried a number of rips. all converted in different formats. resolutions and bit rates still lose sync. anybody got any ideas

same problem here..anybody who knows how to solve this problem?

which version of TCPMP are you using?

doesnt matter which i use,even with coreplayer it goes out of sync
this problem i did not have with mda pro

im affraid this is all to do with the ati chipset and tcpmp, until a fix is found this is going to happen. the best i can get is about 4 minutes. and ive tried most variations in frame size, rate, and bit rate, even files which play at 120% still lose sync.

i went back to watching movies on my psp partly because of this and also as the picture quality is much better as well!

Strange. I use TCPMP to watch all the films and TV shows I download from torrents, and they all play fine. I've never had any problems with the sound going out of sync.

I also never have any out of sync problem. This device rocks for video playback, by my standard. I do lots of youtube and downloaded movies, and the picture is really really good with TCPMP.

I converted a dvd movie to avi 1400MB(high settings) and with this video i have no out of sync.Very strange is with 700mb divx xvid movies its going out of sync.

I've the sync problem too in coreplayer and tcpmp.

is it not possible to get codecs to add to pocket media player so it will play divx etc? As far as i know media player supports the graphics chip so performance should be better

if it was possible , someone would have done it woudnt they?
this problem is one of the major sucky things about this device

Posting to an old post, I know, but as I'm also having the audio/video sync problems, I thought I'd ask everybody that DOESN'T have the problem if they'd be so kind as to specify their EXACT settings.
In my case I'm using Core player.
Under Video I'm using ATI Imageon, Video quality = High, Smooth zoom = on, Dither = ticked and Accelaration = unticked (I have problems with it ticked)
Under Advanced I've even ticked Override AVI timing based on Audio, but no difference. I've also changed the A/V offset to -0.45 seconds, as per another post relating to this issue, with no result.
Under buffering my normal buffer size is 4192, set to preload at 70% underrun, with preload for audio set at 65 KB.
I've ticked Microdrive mode. with the buffer size being 16000 KB and the starting point being 1472 KB

The Core Pocket Media Player

I installed this neat little media player and it seemed like it would work fine. So i took one of my dvds and ripped and reencoded into a divx movie. It plays nice and the audio sounds awesome the only thing is the audio is not synced. Its perfectly synced when i play the video on my computer but when i put it on the mogul and play with TCPMP its about 1/2 a second out of sync. Is there a special way to encode it or a buffer tweak i can do i nthe options to make it sync?

Just change the AV sync in TCPMP

Go to
Menu > Tools > Preferences
Select Page > Advanced
Scroll down and for "Manual A/V offset +/-", enter -0.400 to -0.450, whichever suits you best. I have -0.400, but it seems very very slightly off still, so I might change it to -0.450 eventually.
Hope this helps.

HELL YA! i looked at every option but that one. THANKS!

Thanks, helped me a lot to.

Does anyone know the optimum fps/bitrate I can encode an originally 700mb divx file without the titan slowing down?

my tcpmp is having problems playing video. I downloaded it from the 'pocket youtube' site, and whenever I play a video, for instance one I have recorded via the mogul's camera, tcpmp plays about 1 fps.. the same file plays fine in WMP. any ideas? i've played around with the buffering and advanced settings but have not seen any improvement.

Video, What am I doing wrong.

I have tried several trials on video converters and no matter what I do I get great picture but the voice is way behind.
How do I get the voice to catch up with the film. ( sorry I know it is not techy language)

I use MediaCoder to transcode video. It's free.
http://mediacoder.sourceforge.net/
The even got the iPod Edition which u can use for simplicity reason.

Thank you, can you tell me what settings you have used on that programme.

Core player, THE best media player you can get imo.
Will even play .mkv!!!

He is talking about encoding the movie.
You can try Windows Media Encoder (from Microsoft).
It's also free, and does a good job on encoding movies.

hi guys,
i seem to be having the same problem with the whole audio and video out of sync. i have tried a range of format eg. wmv, mp4, 3gp etc but all are about half a second out of sync. i have even tried core player and tmpcp but with no luck. did anybody else have this problem and manage to fix it? any help will be much appreciated

Hello,
I use the HTC Touch HD Video Converter which is very good. He is especially for WVGA 800 x 480 screens, and the quality of the movie is very good.
HTC Touch HD Video Converter v1.21

DVDFab6
I have not (yet) seen the problem with the sound you describe here.
I use DVDFab6 since a while, originally to convert videos to my iPod, but now also to my HD2.
I have a Touch Diamond too, but the screen is a bit too small to watch for longer time and it drains the batteries also very fast. I haven't tried yet fully, but my first tests show me I can do 3-4 hrs of video on one battery and still have enough power left to use it as a phone. Which is very useful if you have to do a lot of short flights.
I use the PS3 settings in DVDFab6 and adjust the display to 800x444 size, depending on the original size. I found that I can not play them directly from Mediaplayer, but if I click on them in the FileExplorer they start playing without any problem.
BTW, also the iPod m4v files play nicely without delays on the HD2

Yeah i have the same problem, the video/audio file is perfect on my pc but about half a second out of each other on my HD2. You can adjust the audio/video sync in core player but it shouldn't be happening in the first place.

hi guys, thanks for your help. i called htc tech support but all they were able to say was perform a hard reset, which sadly didnt fix the problem! even mp4 videos downloaded straight from the net have the same problem. such a shame because apart from that its an amazing phone. will keep trying and post up if i have any luck

I just tried the one that Braakie suggested and although it converted my 700Mb AVI film to a 500Mb MPEG 4 film, when i tried to copy it to my SD card on my HD2 it said the MPEG 4 format wasn't supported. Can someone enlighten me as to what formats are supported and/or what movie player they use.

I'm having the same audio sync issues as others here. I'm encoding using handbrake and when I play it back on the PC it is perfectly in sync. However when I play it back on the HD2 using the HTC video player the audio lags slightly but noticeably behind the video. When I copy it to my wife's Touch HD it plays fine, so it seems to be a problem with the HD2 software.
I'm running the stock Vodafone 1.43 ROM with all hotfixes applied. Will a ROM update fix this? Anyone else with this ROM having/not having this problem?
I'd be very grateful for any input.

Chaps,
Somewhere on XDA is Chainfire's video driver update (or a reference to it) which you should find and install to help overcome the lip synch issue.
If you can't find it using Search...http://www.google.com/advanced_search?q=+site:http://forum.xda-developers.com&hl=en&lr=&as_qdr=all then go onto the Modaco site and its there somewhere under the Toshiba TG01 device.
Good hunting.
WB

Thanks for your help - I've found the driver here:
http://forum.xda-developers.com/showthread.php?t=592663
However, as far as I can see that's a 3D OpenGL driver and not something that I would expect to affect video/audio synchronisation. Unless, of course, you had the same problem and this fixed it for you? I don't really want to mess about with video drivers unless I'm sure it will fix it.

I was a little dubious and cautious myself but installing the driver did seem to make a difference, sufficient for me not to notice it as much.
Installation is a personal choice. You might want to make a full backup of your device using, say, SPB Backup, before you install. That way you can do hard reset and restore if you don't like the driver.
All the best,
WB

I have the same problem with youtube vids too, just had a replacement hd2, but it's just the same, skyfire, coreplayer, youtube you name it, audio lags the video...
Real pain in the butt for a device who's main feature is a huge screen...!!!

Well I installed the 3D driver, which was easy enough, but unfortunately it made no difference at all to the video/audio sync in either of the two driver modes so I uninstalled it again. (No need for a hard reset, thankfully). I'm using the video in this thread to test since you can easily tell whether it's properly in sync or not.

Oh well, it was worth a try - thanks for the suggestion.

Coreplayer 1.3.6 Judder - stock ROM 1.48 (SOLVED)

I've done a search and read many posts about coreplayer performance on the HD2. Most have no problems but some do and i'm one of them.
I have no problem playing the files using these settings from member Shasarak (thanks mate):
Options/Video and activate Dither, then "smooth zoom always" rather than "smooth zoom 50%". You will get substantially better performance if you then go into the DirectDraw settings page, choose "YUY2" as your overlay format, leave "use device stretching" checked, and uncheck the other two boxes.
I have tried all other settings and combinations but i agree the above gives the best performance.
However, i am still experiencing occassional judder and it's annoying me.
1). would upgrading to stock ROM 1.66 make a difference?
2). is there ANYTHING else i can do to stop the judder? i've already tried disabling background tasks, wifi etc
3). The audio is also very slightly out of sync, it's delayed, it's minor but i notice it. It happens on all videos, they are all .avi I've not seen anyone complain of this before.
Thanks

With regards to uadio sync:
Menu --> Tools --> Settings
Select the 'Advanced' page
Manual A/V offset let's you adjust the audio sync

The judder is most likely due to the format the videos are encoded in just eating too much CPU. How do you encode them?

I don't encode them, just downloaded movies in the common divx/xvid format. I played movies on my old N96but re-encoded them to mp4 as it didn't play avi and i never tried coreplayer on it.
Perhaps i should try re-encoding, but don't see why this phone couldn't handle a standard 700mb divx avi.

cheers mate, you are the man! putting a -0.300 has made it much better, not sure why it would be out like that on all movies? I'm very happy with that What do the other 2 settings do - soft drop tolerance & hard drop tolerance?
now just to fix the juddering.
I've found, and i think someone else suggested this in another thread, that if you pause it for a moment it sorts itself out. Would rather not have to do that but i don't see a way around it

The standard ~1h30 700MB divx movies I've tried to play all worked nicely. But sorter ones of the same size (meaning more bitrate) could start being too much load. Just try and do a benchmark in coreplayer with a video that causes problems, if you have less than about 150% average playing speed you might start getting drops.

It may help to put the phone in "Airplane Mode"; if it's checking for email messages in the background while playing it will judder like crazy. Use the task manager to kill off any other running applications as well....

I come to the conclusion that this phone just can not handle playing divx/xvid in avi very well, and i'm not sure why it can't.
I have gone back to my old ways of converting the video to mp4 using winavi mp4 converter, this also cures the problem of any files that have ac3 audio as it converts that as well.
On my 8 year old computer it would take 30 mins to convert a 700mb film, i have since bought a quad core Dell running 64 bit windows 7 and it converts in less than 10 mins!!
Smooth as butter now but a shame i have to go back to doing this. But at least the files will play in coreplayer, windows media and htc's player so plenty of choice
If anyone wants the settings i use for winavi mp4 converter then just ask away. It's not free but mine was if you get what i mean
EDIT:
I HAVE FOUND THE REAL PROBLEM, IT'S MY COREPLAYER! IT STARTED STUTTERING THE MP4 FILE THIS MORNING, WHEN I SWITCHED TO WINDOWS MEDIA OR HTC PLAYER IT WAS FINE 9OBVIOUSLY COULDN'T DO THIS BEFORE AS NEITHER OF THOSE PLAYERS SUPPORT AVI)
I JUST TRIED COREPLAYER AGAIN AND IT'S PLAYINNG THE SAME MP4 FILE FINE NOW, MUST BE SOMETHING WRONG WITH MY COREPLAYER, WILL GET ANOTHER VERSION.
WHAT A DRAMA AND SORRY FOR BORING YOU ALL WITH IT LOL

Audio sync issues on movies

I re-encoded some of my video's using handbreak to a 800x480 resolution to save on space and I noticed that all of them have audio sync issues when played on the phone but nothing on the PC, moving the original files to the phone also has no audio sync issues.
Im encoding using high profile and nothing else much is changed, anyone know whats causing this ?
This happens with both the stock player and mvideo..

Gave up on Handbrake a long time ago for that reason, didn't matter what codec I used, everything was always out of sync, either resizing or direct scaling.
Real men use MeGUI

I never had this issue with the S1, Ill try to join the real men's club.. give me few mins to try it
EDIT:
Could not get the app to work, after it performs an auto update the updatecopier something crashes and deletes .exe file ~_~

Which version? Probably don't need to update, should be enough profiles.

2028, it auto updates a lot of stuff. ill try to skip the update.
EDIT:
I dont know how to properly use this app, I added a test file on the queue and it starts to process it then I get an error result on the queue, its also asking for some avsynth something.

Yeah, you need avisynth, among other things.
MeGUI isn't really for beginners, but is straightforward enough if you have the time. It's not a one-click job. It's still well worth it IMO - you can convert just about anything to anything after a DVD rip, and the quality is as good or as bad as you want it to be.
If all you're after is something to downscale existing avi/H264/MKVs, I think avisynthdemux will do it - correct me if I'm wrong anyone, been a while since I've used it.
Here's a link to a quite old wiki for MeGUI, but it should be good enough if you're still interested.
hthttp://mewiki.project357.com/wiki/Guides/Basic_Guidetp://
http://www.doom9.org/ is good for all things video.

Ill give it another go a little later, only if it would update properly.

What OS do you use? Heard Win7 64-bit users have had some problems.
Forgot to check my version of MeGUI (at work now), but it works flawlessly with my W7 x86.
Can send all necessary files to you this weekend if you're still interested.

Windows 7 64bit Ultimate.
I tried the vids encoded with handbreak on an S1, theres no audio sync issue.
If you can just compress them into a single zip file.

Of course. Will do it tomorrow sometime (+1 GMT here).

So I've finally gotten the app to work after all this time and still getting the same audio sync issues, I tried encoding with a CUDA based app and still get the same problem.. Could it be an issue with the source file? But it plays perfectly fine on my PC and on the Galaxy S1..

Got the same probleme using SUPER. In the reencoded video sound is about 250 msec behind video. Tried various containers but it's all the same. There are two ways to fix it. Rather wait for incredible Coreplayer to be released for android (you can set and audio sync offset manualy there) or set an offset while encoding. It'll take some time to find the right offset value, but as far as I can see the lag is constant and doesn't depend on file type or resolution, so once found the right value can be used for all video files.
I have the same 250 msec lag in all flash videos in any browser (e.g. from youtube). Still can't find the way to fix it.
Upd
I was wrong that files were ok on PC. The source file is really in sync on PC, but it's also in sync on SGS2. The reason I decided to reencode this file was that it played flawlessly for 10-15 sec, then became choppy for about 5 sec and then played flawlessly again. When reencoding the video file programm extracts elementary audio and video streams from the container, makes the given operations and joins them back together in the output file. Some tomes the source file has wrong or insufficient data (like offset, pulldown, FPS, etc.) that makes an output file out of sync.I tried to remux my source file in the same container just to check that elementary streams can be extracted and joined together with no defect. The result was dreadfully out of sync. The offset value I foud later was -1250 msec (1,25 sec). I made a remux of a source file with offset found and used remuxed file as a source for reencoding to DivX (avi). 1 minute long fragment played flawlessly with stock videoplayer (using hadware acceleration I gues) with perfect sync. Now whole file is being encoded.
Post your files that are out of sync on SGS2 here.

MX Video Player sorts it
I've found that some of my DVD rips made using Handbrake play out of sync on my GS2 which is disappointing. Most are fine, but the ones that aren't play fine on the PC, so it's not a Handbrake encoding issue.
The solution I've found is to use MX Video Player (better than Mobo Player). This allows me to choose software decoding instead of hardware coding for problem videos, and this cures the audio out of sync problem. Slightly disappointing that there appears to be an issue with the GS2 hardware decoder for some files, but at least the amazing CPU has no problem with S/W decoding.
MX Video Player is excellent and worth trying even if you don't have audio sync issues.
