__lasx_xvldx does not accept a pointer to const (in fact,
no function in lasxintrin.h does so), although it is not allowed
to modify the pointed-to buffer. Therefore this commit adds a wrapper
for it in order to constify the H264Chroma API in a later commit.

Yeah, doesn't really matter what of the two we check for.
Type and DDA API should always exist in tandem.

This is possible now that the HEVC DSP API treats them as const.
Also constify the AVFrames whose data is used as source in such
cases.

The generated files are endian-dependent, so no checksums
may be part of the ref files.
Fixes ticket #9854.

It is actually untested whether this fixes ticket #9854
as the commit message claims. I will ask the author of #9854
to test it.

The output file (even the filesize) of the recently added
EXR tests depends on the endianness; therefore checksums
of these files must not be part of the ref file. Therefore
this commit adds an option (unused for now) to disable these
checksums on a per-test basis.
In order to avoid having to chec
Very weird decision by Microsoft there for sure.

The DXGI_OUTDUPL_FRAME_INFO type isn't available in Windows API
subsets other than "desktop", while the IDXGIOutput1 interface is

This fixes compilation for UWP/"Windows Store" configurations (and

It has been deprecated in 94d68a41fabb55dd8c7e59b88fe4a28a637d1e5f
and can't be set via AVOptions. The only codecs that use it
(the MPEG-1/2 encoders) have private options for this.
So remove it.

Recently libFLAC gained the ability (not in any released version yet

keep complexity reasonable, the choice was made to limit residuals
to 32-bit integers, which the encoder must make sure of. In case
