Hi @notedit
I am trying to get RTMPSink to work. I had to modify webrtc/source.py to use H264 instead of VP8 as follows

diff webrtc/source.py.orig webrtc/source.py
51,52c51,52
< videotestsrc ! videoconvert ! queue ! vp8enc deadline=1 ! rtpvp8pay !
< application/x-rtp,media=video,encoding-name=VP8,payload=97,clock-rate=90000 ! queue

videotestsrc ! videoconvert ! queue ! x264enc ! rtph264pay !
application/x-rtp,media=video,encoding-name=H264,payload=98,clock-rate=90000 ! queue
66c66
< # self.video_caps = Gst.caps_from_string('application/x-rtp,media=video,encoding-name=VP8,payload=97,clock-rate=90000')

---

    # self.video_caps = Gst.caps_from_string('application/x-rtp,media=video,encoding-name=H264,payload=98,clock-rate=90000')

< videotestsrc ! videoconvert ! queue ! vp8enc deadline=1 ! rtpvp8pay ! queue

    videotestsrc ! videoconvert ! queue ! x264enc ! rtph264pay ! queue

98,100c98,99
< videoenc = make_element('vp8enc')
< videoenc.set_property('deadline',1)
< videortppay = make_element('rtpvp8pay')

    videoenc = make_element('x264enc')
    videortppay = make_element('rtph264pay')

After that I get further but the RTMPSink pipeline still does not quite work even though the connection between the browser and gstreamer webrtcbin does work

the diff is hard to understand
