For me it doesn't work at all in firefox (37.0.1) but video is shown in Chrome (42.0.2311.90 m).

In no ffmpeg configuration I get audio.

Which settings do you use for getting audio? Could you post your ffmpeg settings?

@jomeier this is a bad aproach all that above. You may want to use gstreamer or janus webrtc gateway, binary.js socket.

Thanks for posting this!

For anyone looking to use this, removing the '-bsf:v dump_extra' option fixed the video for me for some reason.
