Add skip_frame support to qsvenc. Use per-frame metadata
"qsv_skip_frame" to control it. skip_frame option defines the behavior
of qsv_skip_frame.
no_skip: Frame skipping is disabled.
insert_dummy: Encoder inserts into bitstream frame where all macroblocks
are encoded as skipped.
insert_nothing: Similar to insert_dummy, but encoder inserts nothing.
The skipped frames are still used in brc. For example, gop still include
skipped frames, and the frames after skipped frames will be larger in
size.
brc_only: skip_frame metadata indicates the number of missed frames
before the current frame.

There are sill many users of these APIs within libav*, so this commit
introduced too many deprecation warnings, making compilation too noisy and
potentially hiding legit warnings.
Once the remaining users are ported, this can be reapplied.
This reverts commit 76d0038579b90cd572e03fa174d5557776ae83d4.

Replaced by lavu/tx. Dedicated code soon to be removed, replaced with
a simple wrapper code.
|
|
This is a more explicit iteration API rather than using the "magic"
av_dict_get(d, "", t, AV_DICT_IGNORE_SUFFIX) which is not really
trivial to grasp what it does when casually reading through code.

summary: This patch modifies the `curves` filter with new `interp` option
to let user pick the existing natural cubic spline interpolation
and the new PCHIP interapolation.
reason: The natural cubic spline does not impose monotonicity between
the keypoints. As such, the fitted curve may vary wildly against
user's intension. The PCHIP interpolation is not as smooth as
the natural spline but guarantees the monotonicity. Providing
both options enhances users experience (e.g., reduces the number
of keypoints to realize the desired curve). See the related bug
report for the example of an ill-interpolated curve.
alternate solution:
Both Photoshop and GIMP appear to use monotonic interpolation in
their curve tools, which were the models for this filter. As
such, an alternate solution is to drop the natural spline and
go without the `interp` option.

To be useful for adaptive thresholding with threshold filter.

This enables overriding the rotation as well as horizontal/vertical
flip state of a specific video stream on the input side.
Additionally, switch the singular test that was utilizing the rotation
metadata to instead override the input display rotation, thus leading
to the same result.

The FF_PAD_STRUCTURE is too complex for doxygen to be able to
properly handle, resulting in completely broken AVBPrint documentation.
To fix that, tell Doxygen what to expand that macro to.

Add an AV_PIX_FMT_NE macro for RGB32FBE/RGB32FLE and also one for
RGBA32FBE/RGBA32FLE for packed 32-bit float RGB samples, and also
packed 32-bit float RGBA samples, respectively.

Apparently this option was intended (the context contains a
currently-unused frame_rate field), but was never added. This results in
the output timebase being unset after config_output(), so the input
audio timebase ends up being used for video output, which is clearly
wrong.
Add an option for setting output video framerate. Also set output frame
durations.

It has been deprecated in favor of the aresample filter for almost 10
years.
Another thing this option can do is drop audio timestamps and have them
generated by the encoding code or the muxer, but
- for encoding, this can already be done with the setpts filter
- for muxing this should almost never be done as timestamp generation by
the muxer is deprecated, but people who really want to do this can use
the setts bitstream filter

Users can't make anything with its content.
Making it opaque might allow us to avoid one level of indirection.

avcodec_enum_to_chroma_pos() and avcodec_chroma_pos_to_enum()
deal with enum AVChromaLocation which is defined in lavu.
These functions are therefore replaced by
av_chroma_location_enum_to_pos() and av_chroma_location_pos_to_enum().
This commit provides the necessary deprecations. Also already make
these functions wrappers around the corresponding lavu functions
as not doing so would force one to disable deprecation warnings.

They are also frequently used in libavformat.
This change does not cause any breakage as avcodec.h

There is no check for whether these supposedly redundant PPS
are actually redundant. One could check via memcmp which would
work in practice* (because all content buffers are initially
zero-allocated), but this is not portable as compilers may
trash padding inside structures as they wish.
In case the PPS is not really redundant the output is garbage.
This happens with several files from the FATE-suite. E.g.
h264-conformance/CVCANLMA2_Sony_C.jsv doesn't decode correctly
any more, whereas h264-conformance/CABA3_TOSHIBA_E.264 even
fails in ff_cbs_write_packet(), because the inferred value
of num_ref_idx_l0_active_minus1 mismatches with the value set
in the slice (this happens when num_ref_idx_l0_default_active_minus1
changes in the PPS; the value in the slice header is inferred from
the original PPS's num_ref_idx_l0_default_active_minus1).
*: Unless slice_group_id is used, i.e. unless slice_group_map_type
is six.

~4x faster than the C version.
The shuffles in the 15pt dim1 are seriously expensive. Not happy with it,
but I'm contempt.
Can be easily converted to pure AVX by removing all vpermpd/vpermps
instructions.
