Niklas Haas ce457bfccd swscale/slice: fix init of 32 bpc planes ... In input.c and output.c and many other places, swscale follows the rule of using 15-bit intermediate if output bpc is <= 8, and 19-bit (inside int32_t) intermediate otherwise. See e.g. the comments on hyScale() on swscale_internal.h. These are also the coefficients that yuv2gbrpf32_full_X_c() is using. In contrast to this, the plane init code in slice.c (function fill_ones) is assuming that we use 35-bit intermediates (inside 64-bit integers) for this case, seemingly added by commit b4967fc71c with no further justification. This causes a mismatch whenever the implicitly initialized plane contents leak out to the output, e.g. when converting from grayscale to RGB. Fixes: ticket #10716 Signed-off-by: Niklas Haas <git@haasn.dev> Sponsored-by: Sovereign Tech Fund		4 weeks ago
