[FFmpeg-devel] [PATCH 2/5] avcodec/error_resilience, mpeg12dec: Remove always-true checks

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

Having a decode_slice callback is mandatory for HWAccels;
the only exception to this (and the reason why these checks
were added) was XvMC, but it is no more since commit
be95df12bb06b183c8d2aea3b0831fdf05466cf3.
