Hi guys,
Any of you have experience using the '*start_recording()*' function of the RTPENGINE in a WebRTC scenario?.
At this point, I am able to record the stream but I am not able to play them. The output is a .pcap file in a raw format. I have tried the conversion: raw -> H264 -> mp4/avi (with different tools: videosnarf, x264, ffmepg) and not luck.
Do you know the right way to convert those stream in raw format?.
Any hint will be appreciated.
Regards,
Alberto,
Would you not first need to extract only the raw payload of every RTP frame, without encapsulating protocol headers?

Hi Alex,
Thanks for your quick reply.
The output .pcap file is not supposed to have ethernet headers according to https://github.com/sipwise/rtpengine , section: recording-format. Not sure if that answer your question.
Thanks !

Alberto,
But does it have IP, UDP or RTP headers?

Wireshark has (some) support for extracting media from RTP streams. It supports some audio codecs but I have no idea about video. Might be worth looking into, anyway.
