<div>Hi Edward,</div> <div> </div> <div>Thanks for your help. </div> <div> </div> <div>I found out that my pipeline was actually muxing both audio and video, despite gstreamer giving that error. Also gstreamer playbin itself was not capable of playing the movie. VLC player could play it, though it got the duration wrong. Quicktime could not play it. So I guess it again boils down to the bug/s in ffmpeg regarding handling audio duration which we discussed in another mail thread. So let me start looking into it. <br> </div> <div>Once again, I really appreciate your help.</div> <div> </div> <div>Regards,</div> <div>Deeptendu<br> </div> <div><span class="gmail_quote">On 11/7/06, <b class="gmail_sendername">Edward Hervey</b> <<a href="mailto:bilboed@gmail.com">bilboed@gmail.com</a>> wrote:</span> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hi,<br><br>On 11/7/06, Deeptendu Bikash <<a href="mailto:dbikash@gmail.com">dbikash@gmail.com</a>> wrote: <br>> Hi,<br>><br>> I'm using the latest CVS version of gst-ffmpeg (<a href="http://0.10.1.1">0.10.1.1</a>) to mux audio and<br>> video into a mov file.
