* libavutil/hwcontext_d3d11va: adding more texture information to the D3D11 ↵Artem Galin2021-09-08
| | | | | | | | | | | | hwcontext API Microsoft VideoProcessor requires texture with D3DUSAGE_RENDERTARGET flag as output. There is no way to allocate array of textures with D3D11_BIND_RENDER_TARGET flag and .ArraySize > 2 by ID3D11Device_CreateTexture2D due to the Microsoft limitation. Adding AVD3D11FrameDescriptors array to store array of single textures instead of texture with multiple slices resolves this. Signed-off-by: Artem Galin <artem.galin@intel.com>
* avutil/opt: Document actual behaviour of av_opt_copy a bit moreAndreas Rheinhardt2021-08-17
| | | | | | | | | In particular, document that av_opt_copy() always disentangles allocated options even on error; this guarantee is needed to e.g. properly free duplicated thread contexts in libavcodec on error.

* imgutils: expose av_image_copy_plane_uc_from()Lynne2021-08-14
| | | | | | | | | | | | The reason why the generic av_image_copy_uc_from() doesn't really fit in the case for Vulkan is because some planes may be copied via other methods (such as mapping GPU memory), and if they don't satisfy the strict alignment requirements, a gpu image->gpu buffer->cpu ram copy is performed. We need this for hwcontext_vulkan, and I think this will also be useful to API users like libplacebo who would rather not write a custom SIMD memcpy.
* avutil/common, macros: Move several macros from common.h to macros.hAndreas Rheinhardt2021-07-29
| | | | | | | | | | | | common.h currently contains several things: Math macros, UTF-8 macros, other fundamental macros; furthermore it also contains miscellaneous math functions and it (directly and indirectly) includes lots of other headers. This commit moves the "other fundamental macros" to macros.h which is a more fitting place. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | av_adler32_update() is used by av_hash_update() which will be switched to size_t at the next bump. So it also has to be made to use size_t. This is also necessary for framecrcenc.c, because the size of side data will become a size_t, too.

* lavu/tx: support in-place FFT transformsLynne2021-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lavu: support arbitrary-point FFTs and all even (i)MDCT transformsLynne2021-01-13
| | | | | | | | | This patch adds support for arbitrary-point FFTs and all even MDCT transforms. Odd MDCTs are not supported yet as they're based on the DCT-II and DCT-III and they're very niche. With this we can now write tests.

* libavutil: introduce AVFilmGrainParams side dataLynne2020-11-25
| | | | | | | | This patch introduces a new frame side data type AVFilmGrainParams for use with video codecs which support it. It can save a lot of memory used for duplicate processed reference frames and reduce copies when applying film grain during presentation.
* lavu/buffer: add a convenience function for replacing buffersAnton Khirnov2020-09-28
| | | | | | | A common pattern e.g. in libavcodec is replacing/updating buffer references: unref old one, ref new one. This function allows simplifying such code and avoiding unnecessary refs+unrefs if the references are already equivalent.
