It will request a pad from splitmuxsink without much information on the type of the pad so you are trying to create a video pad twice and splitmuxsink will reject it.<br> <br> You can work around this by explicitly requesting video and audio pads and linking manually.<br> <br> 1) get the pad templates for video and audio from splitmuxsink<br>should I use gst_pad_template_new() to get the template ?<br><br>2) gst_element_request_pad on splitmuxsink for video and audio pads<br>should I use request_new_pad ?<br><br> 3) Use get the pad of your queue3 and queue4 elements<br> 4) use gst_pad_link to link the queues with splitmuxsink pads you have requested.<br> <br><br>Is there any sample app which does it will be much helpful.<br><br>Thanks,<br>Sagar<br></div> </div></body> </html>
