[gst-devel] Muxing video and audio

[sledge hammer]

After a bit of testing myself I discovered the problem. You just need to put queue right after the demuxer(and before the caps). Here's the pipeline that produced a valid avi in my machine:

gst-launch-0.10 -v filesrc location="video.avi" ! avidemux ! queue ! video/x-xvid ! avimux name=muxer ! filesink location="video-audio.avi" filesrc location="audio.mp3" ! mp3parse ! queue ! muxer.
