Comment:

 Fix MHEG-related crash post ffmpeg-sync

 Two changes in here:

 One: don't try to dereference ->info if it is NULL
 Two: use av_new_stream instead of av_add_stream.  The contents are nearly
      identical, but the former actually allocates the ->info.

 I don't think the ->info part is actually used by MHEG itself, but enough
 of
 the generic code for mpeg2ts seems to use it that this seemed to be the
 best
 way to fix this crash.

 Fixes #9747
