[FFmpeg-devel] [PATCH] MV-HEVC decoding

Hi, this second round of the MV-HEVC decoding set should be good enough for inclusion. Changes since the previous set [1] are: * Rebased against master. * Addressed all the review comments. * Now using C23 stdc_trailing_zeros() instead of POSIX-only ffs() (with a fallback for systems lacking stdb
