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?

Alex,
So far they have: IP header and UDP header....not RTP header.
Thanks !

At this point, I am able to record the stream but I am not able to

the conversion: raw -> H264 -> mp4/avi (with different tools:

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.
