Changes in output when truncating bit-depth of RGB frames
when running some local regression tests for the upcoming v4.4 release I
noticed that the output checksum of some RGB test has changed. It seems
to happen when RGB input data having a bit-depth above 8-bit is
truncated to 8-bit and is caused by the change in commit
As the commit is targeted at RGB to YUV conversion I wonder why a
conversion like from gbrp12le to gbrp is affected by this change. Does
the swscaler temporarily convert to YUV when truncating RGB?
