Derek Buitenhuis	113a99270d	doc/encoders: Add documentation for the GIF encoder Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	4 years ago
Anton Khirnov	313c91beb8	ffprobe: stop printing deprecated fields The FF_API macros are private and must not be used by external callers. As the fields in question are to be removed without replacement, just drop them. The fields are: AVPacket.convergence_duration AVCodecContext.time_base AVCodecContext.timecode_frame_start AV_PIX_FMT_FLAG_PSEUDOPAL pixel descriptor flag	4 years ago
Lynne	5ca40d6d94	lavu/tx: support in-place FFT transforms This commit adds support for in-place FFT transforms. Since our internal transforms were all in-place anyway, this only changes the permutation on the input. Unfortunately, research papers were of no help here. All focused on dry hardware implementations, where permutes are free, or on software implementations where binary bloat is of no concern so storing dozen times the transforms for each permutation and version is not considered bad practice. Still, for a pure C implementation, it's only around 28% slower than the multi-megabyte FFTW3 in unaligned mode. Unlike a closed permutation like with PFA, split-radix FFT bit-reversals contain multiple NOPs, multiple simple swaps, and a few chained swaps, so regular single-loop single-state permute loops were not possible. Instead, we filter out parts of the input indices which are redundant. This allows for a single branch, and with some clever AVX512 asm, could possibly be SIMD'd without refactoring. The inplace_idx array is guaranteed to never be larger than the revtab array, and in practice only requires around log2(len) entries. The power-of-two MDCTs can be done in-place as well. And it's possible to eliminate a copy in the compound MDCTs too, however it'll be slower than doing them out of place, and we'd need to dirty the input array.	4 years ago
Ashish Singh	38aea9b041	avfilter: add vif filter This is Visual Information Fidelity (VIF) filter and one of the component filters of VMAF. It outputs the average VIF score over all frames. Signed-off-by: Ashish Singh <ashk43712@gmail.com>	4 years ago

Andreas Rheinhardt	4f49ca7bbc	avdevice/avdevice: Deprecate AVDevice Capabilities API It has been added in `6db42a2b6b`, yet since then none of the necessary create/free_device_capabilities functions has been implemented, making this API completely useless. Because of this one can already simplify avdevice_capabilities_free/create and can already remove the function pointers at the next major bump; given that the documentation explicitly states that av_device_capabilities is not to be used by a user, it's options can already be removed (save for the sentinel).

Bohan Li	82aab8a4ee	avcodec/libaomenc: add support for setting arbitrary libaom options A new key & value API lets us gain access to newly added parameters without adding explicit support for them in our wrapper. Add an option utilizing this functionality in a similar manner to other encoder libraries' wrappers. Signed-off-by: Bohan Li <bohanli@google.com>	4 years ago
