bink supports 16x16 blocks in chroma planes thus we need to allocate enough.

9ee16a0ba2 swscale/input: Use more unsigned intermediates 
Same principle as previous commit, with sufficiently huge rgb2yuv table
values this produces wrong results and undefined behavior.
The unsigned produces the same incorrect results. That is probably
ok as these cases with huge values seem not to occur in any real
use case.

3993a90732 swscale: aarch64: Fix yuv2rgb with negative strides 
Treat the 32 bit stride registers as signed.

Alternatively, we could make the stride arguments ptrdiff_t instead
of int, and changing all of the assembly to operate on these
registers with their full 64 bit width, but that's a much larger
and more intrusive change (and risks missing some operation, which
would clamp the intermediates to 32 bit still).
