If I did not have any logging I could see a message 'Redistribute latency' and if I turned on the logging I got continual error messages being logged 'Reached libmpeg2 invalid state'. I know that the original file can't be too bad since playbin manages to get it to work - so what am I missing?

In your case the reason is that you try to pass a .mpg file (a container format containing compressed media) to elements that only accept rate video. That can't work and you'll have to use a demuxer and decoder first, or use decodebin between filesrc and the queue. </pre> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </pre> </blockquote> </body> </html>
