Maybe you can just record the encoded stream and then play it using other players like vlc, since ffdec_mpeg4 isnt a very recommended decoder. Or even better is file a bug attaching a small video clip. regards kapil <div class="gmail_quote">On Mon, Nov 9, 2009 at 3:15 PM, Mailing List SVR <<a href="mailto:lists@svrinformatica.it">lists@svrinformatica.it</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi all, I'm trying to see the video from a verint nextiva s1970e encoder, according to the manufacter they send an "mpeg4 compliant simple profile stream over rtp/udp", I tryed the following pipeline gst-launch-0.10 -v udpsrc port=2544 ! decodebin ! autovideosink here is the output: Setting pipeline to PAUSED ...
