Audio completely out of sync with video playback. (FFmpeg/Xine/VLC) 12.2/2.6.27.7-smp
 

Hello everyone. Well, I've been in Slack-paradise up until this point!

Been having no end of trouble with getting video playback to work properly. Either the video falls behind or the avi, et. al gets ahead. I've googled extensively, but still can't seem to find the issue. Using ffmpeg with the necessary codecs and sound-output is through alsa. Every player I've tried it with (Xine, gXine, VLC, Codeine) has fallen flat on its face. Mplayer won't install for some reason, saying it has an unmet dependency, which is actually met (cdparanoia).

Nothing seems to be especially strange in vlc's terminal output:

But codeine shows there's a definite problem somewhere:

During all of this X sits at around 30-50% CPU usage, while the players usually stay ~15%.

Recently I've configured my asound.conf file to set my default sound card, as it usually set the microphone on my webcam as default for one reason or another. However, I had the same video/audio problems before then. Flash plays perfectly, though! :P

On a side note, I went ahead with the mplayer install even though it didn't properly locate my cdparanoia, which is of a higher version than the dependency requires. Trying to run it (as su or otherwise) gets this error:

Hope I've provided enough information! I'm not new to Linux at all, but still find myself grappling with a certain bug or puzzle every now and then. Off to try and answer some other users' questions; I feel like I hog you guys too much!

Try the autosync option:
If it does not help, compile an mplayer from source and try again. The source can be found at http://www.mplayerhq.hu

Compiling mplayer hangs on the make command with this error:

Binary codecs have already been installed. I've given demux_nut.c a quick read-through, and nothing really seemed out of the ordinary.

Trying to build mplayer from a SlackBuild script ends with the same problem. Is it really necessary to get videos playing properly? Xine has all of its codecs and links to where mplayer would put them, it's just that videos are unwatchable. Audio playback in all other applications is fine.

When a lib is reported as missing, you can usually install either a package for the lib or the applet package that includes the lib (in this case x264). x264 can be found, for example, at www.slacky.eu > Repository > 12.2 > multimedia. Some other libraries (since I'm sure x264 is just the tip of the dependency iceberg) can be found at ... > 12.2 > libraries. Some other app/library packages can also occasonally be found at www.linuxpackages.net Usually, solving the dependency puzzle involves installing a library, trying the app again, then installing another, etc. until you have finally bludgeoned the app into submission and it runs. Even mplayer will eventually run.

Sometimes after installing all the required libraries, a dependency is still missing: you may have version .so.64 installed, but the stupid app refuses to accept anything but, say, .so.59 Sometimes, in these cases, it will work to go into the directory where the library resides, and make a simlink named for the version of the lib the app expects, and link it to the version of the lib you actually have. If you're reasonably lucky, the app will accept it and will run.

mplayer has configured properly and is running with all of the libraries finally properly linked. However, audio and video are still not in sync. Here's the terminal output; the autosync command suggestion posted above shows no improvement.

I'm intrigued by these lines from your first post:
Specifically, why is xine even looking for smb.conf?

Are you, perchance, trying to play a file from a windows box on a lan?

Secondly, what are the specs of your Linux box?

cheers,

Hi camphor,

You would be better using the svn MPlayer.

Having switched to a clean Slackware 12.2 install, I've properly build Mplayer, Xine, and etc. and have the codecs properly registered for them. However, I still see the same problem with absolutely no counterpart when running applications through WINE or in playing music. I'm working on compiling the latest Slacky build of VLC now, so will post my findings when that's complete. Oddly enough, mplayer doesn't present any error messages or anything this time around, but all videos are still out of sync. Thanks for putting up with me so far. :confused:

EDIT: No go with VLC. Nothing unusual in its output other than a Freetype error and several SVG render problems.

I'm running Suse 11.1 with 4 processors and 4 gigs of ram. For some reason I've run into this same problem playing video and particularly AVI files. From another website I picked up the suggestion to try totem-xine (totem). I did so and that seems to produce a reasonable presentation. YMMV.
