I don't know how to feed the captured rtp stream, my guess is you have to edit the sdp file and resend the stream.
Carl Yes, I am starting to think this could be quite complicated. I have a pcap file with rtp, and I have the related SDPs for the two streams, but after looking into the ffmpeg code a bit it seems like it can only take rtp streams from a network port, not a file, which seems to mean that I would have to: - rewrite the udp headers to change the src and dest addresses to localhost from their original values - probably this means updating the checksums in the udp packets as well - do the same with the sdps - find some way to play the (modified) rtp stream from a file to a localhost udp port (I don’t think ffmpeg can do this, since it can’t take rtp input from a file?) - spawn an instance of ffmpeg, feed it the modified sdp and point it to the localhost port for rtp input to get a decoded version of the audio out The whole thing seems pretty complicated and likely to be quite brittle…unless I am missing something ? _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
