I've already discussed solutions with ivf and h264 byte stream which are
the same as webm but even easier in implementation. They are not applicable.

So, if I have an rtp stream inside my application and want to save it
somehow to a playable media container, I have to wrap this stream to
something that could be transferred by pipe to ffmpeg, for instance to ivf
or to h264 byte stream. The first format requires deep codec parsing to
extract at

Hi,
I agree with Kieran that this doesn't look like it belongs in FFmpeg or in any
media framework. In fact, Wireshark has some support for extracting media from
RTP, and that seems like the right place for it.
With that said, you can't realistically pass RTP packets on the standard input.
It might be interesting. I didn’t find how to pass rtp to ffmpeg stdin.
That is why I started thinking about pcap.
Could you please show an example?

Wouldn't the simplest solution just be a tiny tool that unwraps the pcap
stuff and just passes the packet data out on stdout?
That's assuming ffmpeg allows receiving RTP packets on stdin.

Anyway,

Anyway, I don't suggest you implement this feature. I just want to find a
good entry point to start coding personally.
I need to create a development tool for rtp tracing, and pcap files seem a
good idea because I can grab rtp using

I want to implement something which helps me to play rtp stored in pcap
files.
tcpdump -i lo udp port 5 -s0 -w - | ffplay -i -
The specification of pcap files is really simple and I could create a new
ffmpeg format, but don't know how to process rtp packets extracted from
pcap, because it
