[FFmpeg-devel] [PATCH v2 02/10] swscale: don't omit ff_sws_init_range_convert for high-bit

From: Niklas Haas <git at haasn.dev>

This was a complete hack seemingly designed to work around a different
bug, which was fixed in the previous commit. As such, there is no more
reason not to do this, as it simply breaks changing color range in
sws_setColorspaceDetails for no reason.
