[Libav-user] RTP streaming input and output setting local port fails socket bind

How can I use the same local port for input and output of RTP streams and
avoid the UDP error below?

[udp @ 0e5efd00] bind failed: Error number -10048 occurred

I have one AVFormatContext for output and one for intput, my guess is that
each AVFormatContext creates its own socket and binds to the same port.

I think the correct way is to use the same AVFormatContext for both input
and output, but doing that crashes the application without giving a hint of
what the error is.
