Today I have found something surprisingly (at least for me!). My new conclussion is that the "guilty" is not the avimux, it is the video source!     Look at these two pipelines, the first one records an INVALID avi file, test1.avi, (at least VLC or Windows Media Player can not handle them), but the second one is fine (test2.avi)!! gst-launch-0.10 videotestsrc is-live=true ! 'video/x-raw-yuv,format=(fourcc)I420,width=640,height=480,framerate=(fraction)25/1' ! xvidenc ! queue ! avimux ! filesink location=test1.avi gst-launch-0.10 videotestsrc num-buffers=500 ! 'video/x-raw-yuv,format=(fourcc)I420,width=640,height=480,framerate=(fraction)25/1' ! xvidenc ! queue ! avimux ! filesink location=test2.avi     Why? What's happen? Any explanation? How can I record an .AVI file from a v4lsrc for example? ...     Thanks in advance.     Regards,     LD. </body> </html>
