[FFmpeg-devel] [PATCH 5/9] checkasm/motion: Don't allocate AVCodecContext

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

Instead use one on the stack to avoid pulling in all
of libavcodec.

ff_me_cmp_init() reads only codec_id (checks whether it is Snow)
as well as the bitexact flag. The first check has been added in
cfe675269bf44c49590e9076b5d2cd2503804f98 due to alignment;
I don't know whether this is still an issue, as the ticket referred
to in this commit does not refer to track (or at least the current
incarnation of it), but to something else.
