[gst-devel] Audio playback not sync with video playback

[Rodney Dowdall]

Hello Eric

I think you need to set sync=true on the video and audio syncs, so try:

gst-launch filesrc location=/home/out_CR.avi ! avidemux name=demux demux.audio_00 ! queue ! mad ! volume volume=0.5 ! alsasink sink=true  demux.video_00 ! queue ! video mpeg,scalewidth=512,scaleheight=288 ! mympeg4dec ! ximagesink sync=true

I think that should work.
