[FFmpeg-devel] [PATCH 2/2] avcodec/vc1: support multi-slice field interlaced pictures with hwaccel

When using hardware accelerated decoding for multi-slice field interlaced pictures, only the first slice was decoded. This patch adds the neccesary looping over the remaining slices that may exist in field interlaced pictures. Additionally, we align the calculation of mby_start for the second fie

[FFmpeg-devel] [PATCH 1/2] avcodec/vaapi: slice_vertical_position starts from zero for the second field
