can we set a bigger block size to the motion vector in ffmpeg
16 août 2022, par M.AkyuzluIn the FFmpeg v5.0 function
add_mb
at line 1562 inmpegvideo.c
file

static int add_mb(AVMotionVector *mb, uint32_t mb_type,
 int dst_x, int dst_y,
 int motion_x, int motion_y, int motion_scale,
 int direction)
{
 mb->w = IS_8X8(mb_type) || IS_8X16(mb_type) ? 8 : 16;
 mb->h = IS_8X8(mb_type) || IS_16X8(mb_type) ? 8 : 16;
 mb->motion_x = motion_x;
 mb->motion_y = motion_y;
 mb->motion_scale = motion_scale;
 mb->dst_x = dst_x;
 mb->dst_y = dst_y;
 mb->src_x = dst_x + motion_x / motion_scale;
 mb->src_y = dst_y + motion_y / motion_scale;
 mb->source = direction ? 1 : -1;
 mb->flags = 0; // XXX: does mb_type contain extra information that could be exported here?
 return 1;
} 



Depending on the MB_TYPE the block could take 8 or 16 pixels at one time so can we set the width and the height of the motion block to a bigger range in order to reduce the motion vector total length ?


that could hurt the quality of the image but I'm ok with that.
