Is your problem still valid for small .avi files. If yes try large .mov/.mp4 files using qtdemux ? <div class="gmail_quote">On Wed, Mar 3, 2010 at 6:30 PM, Sedji Gaouaou <<a href="mailto:sedji.gaouaou@atmel.com">sedji.gaouaou@atmel.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Well, I have now tested this command line: gst-launch -v filesrc location= mnt/video/AVI/MPEG4/Myfile.avi ! <div class="im">avidemux name=demux demux.video_00 ! queue ! x170 output=RG </div>B16 inbuf-thresh=0000 output_width=480 output_height=240 ! fakesink sync=True And it is really peculiar because the file play until the end,and the timestamp displayed are all correct...
