* Bump Versions before release/4.4 branchMichael Niedermayer2021-03-20

* avutil/adler32: Switch av_adler32_update() to size_t on bumpAndreas Rheinhardt2021-03-19
| | | | | | | | | | 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.

| | | | | | | | | | Base escaping only escapes values required for base character data according to part 2.4 of XML, and if additional flags are added single and double quotes can additionally be escaped in order to handle single and double quoted attributes.

* 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.
* mpegvideo: use the AVVideoEncParams API for exporting QP tablesAnton Khirnov2021-01-01
| | | | | | | | | | Do it only when requested with the AV_CODEC_EXPORT_DATA_VIDEO_ENC_PARAMS flag. Drop previous code using the long-deprecated AV_FRAME_DATA_QP_TABLE* API. Temporarily disable fate-filter-pp, fate-filter-pp7, fate-filter-spp. They will be reenabled once these filters are converted in following commits.
* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Requires some extraneous top side and bottom front channels to be defined.

* hwcontext: add av_hwdevice_ctx_create_derived_optsLynne2020-05-23
| | | | | | | | | | | | | This allows for users who derive devices to set options for the new device context they derive. The main use case of this is to allow users to enable extensions (such as surface drawing extensions) in Vulkan while deriving from the device their frames are on. That way, users don't need to write any initialization code themselves, since the Vulkan spec invalidates mixing instances, physical devices and active devices. Apart from Vulkan, other hwcontexts ignore the opts argument since they don't support options at all (or in VAAPI and OpenCL's case, options are currently only used for device selection, which device_derive overrides).

* hwcontext_vulkan: expose enabled device and instance extensionsLynne2020-05-10
| | | | | | | This solves a huge oversight - it lets users reliably use their own AVVulkanDeviceContext. Otherwise, the extensions supplied and enabled are not discoverable by anything outside of hwcontext_vulkan. Also clarifies that any user-supplied VkInstance must be at least 1.1.

* lavu/tx: implement 32 bit fixed point FFT and MDCTLynne2020-02-13
| | | | | | | | | | | | | | | | | | | | Required minimal changes to the code so made sense to implement. FFT and MDCT tested, the output of both was properly rounded. Fun fact: the non-power-of-two fixed-point FFT and MDCT are the fastest ever non-power-of-two fixed-point FFT and MDCT written. This can replace the power of two integer MDCTs in aac and ac3 if the MIPS optimizations are ported across. Unfortunately the ac3 encoder uses a 16-bit fixed point forward transform, unlike the encoder which uses a 32bit inverse transform, so some modifications might be required there. The 3-point FFT is somewhat less accurate than it otherwise could be, having minor rounding errors with bigger transforms. However, this could be improved later, and the way its currently written is the way one would write assembly for it. Similar rounding errors can also be found throughout the power of two FFTs as well, though those are more difficult to correct. Despite this, the integer transforms are more than accurate enough.

* avutil/eval: add function to track variable useGyan Doshi2019-11-17
| | | | | | | | | | | | | | | | | | | | | 1)Some filters allow cross-referenced expressions e.g. x=y+10. In such cases, filters evaluate expressions multiple times for successful evaluation of all expressions. If the expression for one or more variables contains a RNG, the result may vary across evaluation leading to inconsistent values across the cross-referenced expressions. 2)A related case is circular expressions e.g. x=y+10 and y=x+10 which cannot be succesfully resolved. 3)Certain filter variables may only be applicable in specific eval modes and lead to a failure of evaluation in other modes e.g. pts is only relevant for frame eval mode. At present, there is no reliable means to identify these occurrences and thus the error messages provided are broad or inaccurate. The helper function introduced - av_expr_count_vars - allows developers to identify the use and count of variables in expressions and thus tailor the error message, allow for a graceful fallback and/or decide evaluation order.
