[FFmpeg-devel] [PATCH] avutil/imgutils: don't fill data pointers for missing planes

[James Almer]

The size for a previous plane doesn't signal the presence of another after it.
If the plane is present, av_image_fill_plane_sizes() will have returned a size
for it.

Fixes a regression since 3a8e927176.
