swscale rejects files with reserved colorspace tags after filter
reinit
Comment:
I think there are two issue here:
One is the filter reinit somehow triggers swscale, while running on the
isolated portion alone does not.
The other is that swscale now rejects trc/prim=reserved. I'm not sure why
it only triggers on filter reinit, but it's possibly to do with some other
condition for when swscale
In either case, to be clear, this is an illegal/broken file, as it
contains coded values which are marked as reserved by the spec. That
swscale now correctly rejects invalid colorspace tags instead of
implicitly accepting them in the past is indeed a regression in
functionality, but a fix in terms of correctness.
As a possible resolution to the second error, what if we tie this behavior
to e.g. "-err_detect compliant" (as an opt out), or "-err_detect
ignore_err" (as an opt in)?
