-Subject: [PATCH 18/24] dxva-mpeg2 Allocate slices array dynamically - fixes
- videos with > 175 slices. They used to result in
- images with a black bottom.
-
-sample on team ftp samples/PR471/too_many_slices.ts
-
-Inspired by the vaapi code to reallocate the slices array for each new slice.
-Could be more efficient if the array could be preserved for all frames and
-freed only at the end of the video, but there doesn't seem to be anywhere
-appropriate to free the memory at the end.
-
-Alternative is to allocate the proper size straight away for a new frame,
-instead of realloc'ing for each slice.
