<br>But if the frame rate is 60 then the file duration should be half , right ?<br><br>Can you dump the file before giving it to avimux and check the number of frames ? <br><br><div class="gmail_quote">On Tue, Jul 20, 2010 at 9:41 AM, Sandeep Prakash <span dir="ltr"><<a href="mailto:123sandy@gmail.com">123sandy@gmail.com</a>></span> wrote:<br>

Hi Prabhulinga,<br>

>From your ffmpeg command line<br>
<div class="im"><br>

<br>
</div>we can also observe that the framerate is actually 60 (59.94 to be exact)<br>
and not 30<br>
as you are saying. So somewhere the framerate is getting modified. This<br>
explains the<br>
video duration getting awry.<br>
<br>
Can you attach some logs that will show the caps at each element. Try<br>
setting the<br>
GST_DEBUG=3 env variable.<br>
<br>
Also you can try to disable your frame completion logic and check whats the<br>
outcome.<br>
<br>
