ffmpeg | branch: master | Timur Aydin <ta at taydin.org> | Sat Nov  5 01:15:44 2016 +0300| [7746103227195b4d106ce6090d17dc6fd36de683] | committer: Michael Niedermayer

avformat/rtpdec: Add support for 24 bit RTSP audio playback

When ffplay is used to play from the RTSP URL that serves 24 bit audio
content, ffplay fails to recognize the audio codec format. The attached
patch adds support for playing 24 bit audio content over RTSP by
defining a dynamic payload handler for "L24".
