<p>The code needs to be updated to be able to catch <code>a=rtcp-fb:</code>, probably it was not a common attribute when the sdp parser was written and not covered at that time (iirc, it was <a class="user-mention" data-hovercard-type="user" data-hovercard-url="/users/ovidiusas/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/ovidiusas">@ovidiusas</a> writing the sdp parser).</p>
<p>The solution right now is to use <code>subst_body()</code> function to remove lines from sdp matching <code>a=rtcp-fb:ID</code>, replacing the ID with the corresponding codec numeric ids:</p>

</ul>
<p>If you do not want video media stream, there is a function to remove it all together:</p>
