[FFmpeg-devel] [PATCH] Free AVStream->info in chained muxers

[Martin Storsjö]

This fixes memory leaks in the RTSP muxer and RTP hinting in the
mov muxer present since SVN rev 25418.
---

The cleanup of muxers should probably be wrapped up in a normal
cleanup function, like av_close_input_stream for demuxers, but
that's for a later patch.
