ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Sun May 12 18:47:25 2024 +0200| [182e647a64bc85f74a03da9f1c96c9111e7b27d4] | committer: Andreas Rheinhardt
avcodec/me_cmp, motion_est: Move me_(pre_)?_cmp etc. to MotionEstContext
MECmpContext has several arrays of function pointers that
are not set by ff_me_cmp_init(), but that are set by users
to one of the other arrays via ff_set_cmp().
One of these other users is the motion estimation API.
It uses MECmpContext.(me_pre|me|me_sub|mb)_cmp. It is
basically the only user of these arrays.
This commit therefore moves these arrays to MotionEstContext;
this has the additional advantage of making motion_est.c
more independent from MpegEncContext.
