The generated capabilities aren't random, they are default, except for the seqnum-base, which RTP says can (should?) be random. Different elements require different capabilities, so these may not hold for your case. However, you can always initialize the capabilities like this:<br>
<br> GstCaps *pSinkCaps = gst_caps_new_simple("application/x-rtp", "media", G_TYPE_STRING, "video",<br> "encoding-name", G_TYPE_STRING, "H264", "payload", G_TYPE_INT, 96,<br>
"clock-rate", G_TYPE_INT, 90000, NULL);<br><br> // Link the pipeline together.<br> if (gst_element_link_filtered(source_, queue_, pSinkCaps)) {<br> ...<br> }<br>
gst_caps_unref(pSinkCaps);<br><br><br><div class="gmail_quote">On Wed, Feb 20, 2013 at 10:05 AM, Saurabh Sabnis <span dir="ltr"><<a href="mailto:sausab@gmail.com" target="_blank">sausab@gmail.com</a>></span> wrote:<br>
