Actually, I don't have access to the client RTSP application. This RTSP
client is embedded in phones like a Nokia with streaming capabilities or
any other phone (so I have no access to those phones).
So I'm interested by both the RTSP/RTP protocol implementation and by
the means to write a compliant video file, by getting the good
parameters from the SDP description and building headers of an AVI file
so that it can be correctly read afterwards by a media player such as
VLC. My application can already export the binary from a RTP packet but
if I just do that (and aggregate the packets' payloads of a same RTP
session), the resulting binary file is unplayable in any video player.
My application already can extract the SDP parameters and can isolate
the payloads from the packets but I have no idea how to export a correct
video file, this is why I wanted to learn about an API of a hint at how
to use this function of the LiveMedia library.
