[FFmpeg-devel] [PATCH v7 3/4] lavf/mpegts.c: set some properties for ARIB caption

[TADANO Tokumei <aimingoff@pc.nifty.jp>]

Some additional properties are set for ARIB caption.
* need_parsing = 0
  ARIB caption doesn't require any parser.
  This avoids "parser not found" warning message.
* need_context_update = 1
  When any profiles are changed, set this flag to notify.
