<p>I am working on a livestream utilizing gstreamers webrtcbin
the whole setup works when using a testpipeline so the webrtc handshake code (on_negotiation, on_ice_candidate etc) is fine</p>
<pre class="gmail-lang-cpp gmail-s-code-block"><code class="gmail-hljs gmail-language-cpp">pipeline = <span class="gmail-hljs-built_in">gst_parse_launch</span>
(<span class="gmail-hljs-string">"videotestsrc ! queue ! "</span>
<span class="gmail-hljs-string">"vp8enc ! rtpvp8pay ! "</span>
<span class="gmail-hljs-string">"application/x-rtp,media=video,payload=96,encoding-name=VP8 ! "</span>
<span class="gmail-hljs-string">"webrtcbin name=webrtcbin_send"</span>, &error);
</code></pre>
<p>But i am trying to use appsrc with VP9</p>
<pre class="gmail-lang-cpp gmail-s-code-block"><code class="gmail-hljs gmail-language-cpp">pipeline = <span class="gmail-hljs-built_in">gst_parse_launch</span>
( <span class="gmail-hljs-string">"appsrc name=CaliCam ! video/x-raw, format=BGR, width=1280, height=960, framerate=5/1 ! videoconvert !"</span>
<span class="gmail-hljs-string">" queue ! vp9enc ! rtpvp9pay ! "</span>
<span class="gmail-hljs-string">" application/x-rtp,media=video, encoding-name=VP9, payload=96 ! "</span>
<span class="gmail-hljs-string">" webrtcbin name=webrtcbin_send"</span>, &error);
</code></pre>
<p>media.peerconnection.video.vp9_preferred is set to true</p>
<p>The result is that the handshake again works fine but the firefox tab
crashes. Does anyone have a idea how i can debug that, or maybe can
point me to a working example of webrtcbin with vp9. Any help is much
apprechiated!!</p>
