In init_planes p->xblen and p->yblen are set to:
            p->xblen = s->plane[0].xblen >> s->chroma_x_shift;
            p->yblen = s->plane[0].yblen >> s->chroma_y_shift;

These are later used as block_w and block_h arguments of
s->vdsp.emulated_edge_mc. If one of them is 0 it triggers an av_assert2
in emulated_edge_mc:
    av_assert2(start_x < end_x && block_w > 0);
    av_assert2(start_y < end_y && block_h > 0);

x265 Reordered the x265_picture fields in the commit

https://github.com/videolan/x265/commit/51b1518de2414431f36eac592db15b667c25a7b9#diff-945b5354d8767dfac13334f2d22cf58fR107

Now the first field is an integer and not an array.

This stimulates the direct pixel mode in Quickdraw decoder.

Update the pictor test to use the pictor codec, as both formats share
the .pic file extension.

Data is stored in separated components so rework decode_rle() to support
stepping and offsets.

Quickdraw packs data as a series of codes that the application is supposed
to handle, but it does not define any order in which they might appear.
Since it's unfeasible to support *all* opcodes defined by the spec,
only handle well-known blocks containing video data and ignore any unknown
or unsupported ones.

Move palette loading and rle decoding to separate functions to resue them
in other blocks and drop format initialization in init since it can
support more formats than pal8.

Validate width and height.

Add appropriate error messages and reduce r, g, b variables scope.
Drop the now redundant line checks in RLE decoding.

Remove PROTMODE as it doesn't make sense for DLLs. Also fixes a warning with the OpenWatcom linker
Export symbols as names rather then ordinals for better compatibility for minor releases.

s->ref_pics[i] is later used as ref argument of interpolate_refplane,
where it is dereferenced.

If it is NULL, it causes a segmentation fault.

If bytes is large enough, bytes*8 can overflow and become negative.

In that case 'bufsize -= bytes*8' causes bufsize to increase instead of
decrease.

This leads to a segmentation fault.
