[FFmpeg-devel] [patch] export pmt and pcr pids from mpegts demuxer

[Mike Scheutzow]

This patch allows a libav application to obtain the pmt pid(s) and pcr 
pid(s) values parsed by the mpegts demuxer. This is useful for 
applications that need the output stream pids to match the input stream 
pids.

The pid values are added to AVProgram.metadata inside the AVFormatContext.

Example: 
    key="pmt_pid" value="129"
    key="pcr_pid" value="1064"

Values are base10.  This patch supports multiple programs per transport 
stream.

Feedback appreciated.
