This test verifies the pixdesc code by comparing the output with and
without a filter which should have no effect on the image. Since the
available pixel formats depend on the byte order of the machine, a
simple reference checksum is not possible.
The test originally tried to solve this by generating a reference file
on the fly. The problem with this is that the test framework expects
the reference file in the source tree, and writing to the source tree
is not allowed.
To avoid complicating the test framework, we instead provide two
reference files and select which to use based on the byte order.

The formats are now supported by NUT.

formats which are not currently supported by NUT and which cannot be
played by ffplay.

target regtest-lavfi_pix_fmts.
The lavfi_pix_fmts test is disabled, this because there are
many tests which are failing, and there are still some output files
which cannot be played by NUT/ffplay.

A patched version of ffmpeg supporting video filters is required for
getting this working; thus make lavfitest is supposed to work only in
the libavfilter repository for now.
