[FFmpeg-devel] [PATCH 02/13] avcodec/mpegvideo_enc: Remove always-false checks

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

In case "!direct" we are not reusing the input buffers
(due to e.g. insufficient alignment), but allocating
new ones. These of course do not alias with the ones
provided by the user, so these checks are always-false.
