* avcodec/mpegvideo_motion: Constify ff_mpv_motionAndreas Rheinhardt2022-08-05
| | | | | | | | | | | | Also constify the corresponding code in mpegvideo.c that handles lowres. (Unfortunately, not everything that is const could be constified: ref_picture could be made const uint8_t* const* if C allowed the safe automatic conversion from uint8_t**; and pix_op, qpix_op could be made to point to const function pointers, but C's handling of const in pointers to arrays is broken.)

* avcodec/mpegvideo_motion: Improve check to remove dead codeAndreas Rheinhardt2021-02-11
| | | | | | | | Several compile-time checks can be improved because mcsel is not used for MPEG-1/2 (it is only used for MPEG-4) and because MPEG-1/2 is the only user of ff_mpv_motion that uses MV_TYPE_16X8 and MV_TYPE_DMV. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/mpeg2dec: Fix motion vector rounding for chroma componentsNekopanda2018-02-11
| | | | | | | | In 16x8 motion compensation, for lower 16x8 region, the input to mpeg_motion() for motion_y was "motion_y + 16", which causes wrong rounding. For 4:2:0, chroma scaling for y is dividing by two and rounding toward zero. When motion_y < 0 and motion_y + 16 > 0, the rounding direction of "motion_y" and "motion_y + 16" is different and rounding "motion_y + 16" would be incorrect. We should input "motion_y" as is to round correctly. I add "is_16x8" flag to do that. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
