<div class="moz-cite-prefix">I'm not sure on the correct way, I have
never done appsrc into webrtcbin. I only know that webrtcbin
needs the caps event on all of its sink pads before a coherent sdp
can be generated. How that occurs, you would need to debug, or
ask someone who can, help you debug.<br>

<div dir="ltr">Hello Matthew,

</div>
<div>Thanks for quick reply,</div>
<div>Basically, I don't provide caps. But I'm pushing samples to
the appsrc - so it has caps by default. But I was trying to
set caps explicitly - with no success.</div>
<div>BTW, I should set caps on webrtcbin or on appsrc sinkpad?
Basically, I was able to proceed, with dirty hack - calling
on_negotiation_needed(webrtcbin, userdata) callback function
manually, right after I configure a transceiver.</div>
<div><br>
</div>
<div>But what is the correct way?</div>

<div>Are you providing caps to your appsrc? I can't
remember if appsrc will delay the caps event until the
first buffer or not so that may be a reason.<br>

<div>I have a pipe:</div>
<div>appsrc->rtph264pay->webrtcbin.sink</div>
<div><br>
</div>
<div>But, when I setting up everything, and pipeline is
not running yet, I received an error: </div>
<div>DEBUG webrtcbin
gstwebrtcbin.c:5722:gst_webrtc_bin_change_state:

LOG webrtcbin
gstwebrtcbin.c:1346:_check_if_negotiation_is_needed:<sendonly>
no negotiation possible until caps have been received
on all sink pads<br>
</div>
<div><br>
</div>
<div>After that, I'm starting pipeline and it working
fine, no issues:</div>
<div><br>
DEBUG webrtcbin
gstwebrtcbin.c:5722:gst_webrtc_bin_change_state:

DEBUG webrtcbin
gstwebrtcbin.c:5722:gst_webrtc_bin_change_state:
changing state: PAUSED => PLAYING<br>
</div>
<div><br>
</div>
<div>And that's all. No more on-negotiation-needed
callback. Nothing.</div>
<div><br>
</div>
<div>How to proceed further with webrtc connection? How
to re-init it after the pipeline is running to make it
call on-negotiation-needed callback?</div>
<div><br>
</div>
<div>Thank you in advance,</div>
