[FFmpeg-devel] [PATCH] libavformat/mpegts.c minor crash and warning avoidance

[Glenn A. Serre]

Good evening,

This patch would be to avoid a compiler warning and avoid a crash that 
happened when I experimented with having mpegts add streams from all the 
PMTs in the transport stream, rather than just from the first one found.

Please note that I can't actually check this in (or at least I shouldn't 
  be able to).  Also, please note that the revision number below is 
against our repository, not the official ffmpeg one.
