This struct has existed in essentially this exact form for decades
(before
It is unused and given that one needs an encoder to produce
packets from AVFrames (as output by filters) this is likely
to remain so, because FILTERDEMDECENCMUX is better for these
scenarios.
The only case where one can use filters without encoders is
with the lavfi input device: It outputs AVPacke
Lots of tests use the framecrc command together with some filters,
so adding a special function for it seems worthwhile. This commit
adds one new one and modifies an already existing one:
All users of FILTERDEMDEC already use framecrc and the more general
FILTERDEMDECENCMUX can be used in scenarios
Also fix the requirements of these tests: Only the anaglyph
tests need a scale filter, yet it has been inserted for all tests
without any check for its presence.

This commit moves some of the functionality from avfilter/colorspace
into avutil/csp and exposes it as an avpriv API so it can be used by
libavcodec and/or libavformat.

Do this by making this test a transcode test.
Also fix the test requirements and don't add this test to FATE_AFILTER;
instead use a new variable and a new target for flvenc-tests.

This enables overriding the rotation as well as horizontal/vertical
flip state of a specific video stream on either the input or output
side.
Additionally, switch the singular test that was utilizing the rotation
metadata to instead override the input display rotation, thus leading
to the same res
Now that we have proper options for defining display matrix
overrides, this should no longer be required.
fftools does not have its own versioning, so for now the define is
just set to 1 and disables the functionality if set to zero.
