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

[ericcardmanNo3]

playing avi (mpeg4/mp3) files result in a bit faster video playback than
audio playback. 
does anyone know such problem? how to solve it?

i do:

gst-launch filesrc location=/home/out_CR.avi ! avidemux name=demux
demux.audio
_00 ! mad ! volume volume=0.5 ! alsasink  demux.video_00 ! queue ! video
/mpeg,scalewidth=512,scaleheight=288 ! mympeg4dec ! ximagesink

if i do:

gst-launch filesrc location=/home/out_CR.avi ! avidemux name=demux
demux.audio
_00 ! queue ! mad ! volume volume=0.5 ! alsasink  demux.video_00 ! queue !
video
/mpeg,scalewidth=512,scaleheight=288 ! mympeg4dec ! ximagesink

audio is more behind video than in first pipeline.

the mympeg4dec decodes frames in hardware.

thx.
