Hello Eric<br>
<br>
I think you need to set sync=true on the video and audio syncs, so try:<br>
<br>
<pre wrap="">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
</pre>
I think that should work. <br>

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.
