VLC 1.1.10 A/V out of sync

Postby milnoc » 12 Jul 2011 03:47

The audio and video is going out of sync with both the Windows and Linux versions of VLC 1.1.10.

My video sources consist of the following:

- XviD/MP3 files: Koepi XviD encoder Quantizer 3, Lame MP3 encoder 48KHz 192 kbps CBR.
- Theora/Vorbis/Ogg live stream via VLC from http://38.104.152.86:11284, also accessible from a compatible browser via http://thecanadianpublic.com/live .

The encoder server is running VLC 1.1.10 under Ubuntu Server 10.04 LTS.

I've reverted the Windows VLC software back to version 1.1.9, and the audio sync problem immediately went away. There were also no sync issues viewing the Ogg stream in Firefox, so the problem appears to be isolated only within the playback/decoder component of VLC.

Both the Linux and Windows VLC installations were operating off their default audio/video values. No changes were made in any of their respective settings.

UPDATE: Reverted VLC on the Linux computer back to version 1.0.6 (default Ubuntu install). The audio sync has been restored.

Hi,

Had the audio sync issues with the 1.1.10 VLC with Ubuntu 10.04.2 LTS .

I removed pulse-audio and installed alsa as a default and got sync back.

Note that i saw the sync issues with some other players as well such as Kaffiene etc. any how now all is good see here how to:

I'll give it a shot. Thanks!

Now I have to figure out what's happening on the Windows side. It's still interesting to see that the same type of bug is happening on two entirely different platforms.

Temporary work around for linux

I created two scripts and called one script start_pulse.sh and stop_pulse.sh and placed them in .gnome2/nautilus-scripts . I did this so I could right click the mouse and go under scripts to start and stop pulse.

what's in the start_pulse.sh file
#!/bin/bash
#this will start pulseaudio
pulseaudio

what's in the stop_pulse.sh file
#!/bin/bash
#this will stop pulseaudio this fixes vlc 1.1.10 audio desync problem
echo autospawn = no|tee -a ~/.pulse/client.conf && killall pulseaudio

remember to give the files executable permissions!!!!

It's a workaround but I like to have people's voices sync up to when their mouth is moving
