* avutil/mem: fix doc for reallocsZhao Zhili2022-05-26
| | | | | | | | | | The doc says those function are like av_free if size or nmemb is zero. It doesn't match the code. av_realloc() realloc one byte if size is zero, which was added by 91ff05f6ac5 ten years ago. realloc() itself in C is implementation-dependent. Make the doc match the longstanding behaviour. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>
* qsv: add requirement for the mininal version of libmfxHaihao Xiang2022-05-25
| | | | | | | | | | libmfx 1.28 was released 3 years ago, it is easy to get a greater version than 1.28. We may remove lots of compile-time checks if adding the requirement for the minimal version in the configure script.

* libavutil: Deprecate av_fopen_utf8, provide an avpriv versionMartin Storsjö2022-05-23
| | | | | | | | | | | | | | | | | | | | | | Since every DLL can use an individual CRT on Windows, having an exported function that opens a FILE* won't work if that FILE* is going to be used from a different DLL (or from user application code). Internally within the libraries, the issue can be worked around by duplicating the function in all libraries (this already happened implicitly because the function resided in file_open.c) and renaming the function to ff_fopen_utf8 (so that it doesn't end up exported from the DLLs) and duplicating it in all libraries that use it. This makes the avpriv_fopen_utf8 / ff_fopen_utf8 function work in the exact same way as the existing avpriv_open / ff_open, with the same setup as introduced in e743e7ae6ee7e535c4394bec6fe6650d2b0dbf65. That mechanism doesn't work for external users, thus deprecate the existing function. Signed-off-by: Martin Storsjö <martin@martin.st>

* x86/tx_float: replace fft_sr_avx with fft_sr_fma3Lynne2022-05-21
| | | | | | | | | | | | When the SLOW_GATHER flag was added to the AVX2 version, this made FMA3-features not enabled on Zen CPUs. As FMA3 adds 6-7% across all platforms that support it, in the interest of saving space, this commit removes the AVX version and replaces it with an FMA3 version. The only CPUs affected are Sandy Bridge and Bulldozer, which have AVX support, but no FMA3 support. In the future, if there's a demand for it, a version of the function duplicated for AVX can be added.
* x86/tx_float: improve temporary register allocation for loadsLynne2022-05-21

* lavu/tx: make slow ISA extension penalties smarterLynne2022-05-21
| | | | | | | | Instead of having a fixed -64 prio penalty, make the penalties more granular. As the prio is based on the register size in bits, decrementing it by 129 makes AVX SLOW functions be avoided in favor of any SSE versions.

* Revert "x86/tx_float: remove vgatherdpd usage"Lynne2022-05-21
| | | | | | | | This reverts commit 82a68a8771ca39564f6a74e0f875d6852e7a0c2a. Smarter slow ISA penalties makes gathers still useful. The intention is to use gathers with the final stage of non-ptwo iMDCTs, where they give benefit.
* x86/tx_float: remove vgatherdpd usageLynne2022-05-20
| | | | | | | | | | | | | | | | | | | | Its performance loss ranges from either being just as fast as individual loads (Skylake), a few percent slower (Alderlake), 8% slower (Zen 3), to completely disasterous (older/other CPUs). Sadly, gathers never panned out fast on x86, even with the benefit of time and implementation experience. This also saves a register, as there's no need to fill out an additional register mask. Zen 3 (16384-point transform): Before: 1561050 decicycles in av_tx (fft), 131072 runs, 0 skips After: 1449621 decicycles in av_tx (fft), 131072 runs, 0 skips Alderlake: 2% slower on big transforms (65536), to 1% (131072), to a few percent for smaller sizes.

| | | | | | | | | | | | | | | | Commit e050959103f375e6494937fa28ef2c4d2d15c9ef implemented passing in modifiers by using the PRIME_2 memory type, which only exists in v2 of the library. To still support v1 of the library, conditionally compile using VA_CHECK_VERSION() for both the new code and the old code before the commit. Note PRIME_2 memory was introduced from VA-API 1.1, so use VA_CHECK_VERSION(1, 1, 0) instead of VA_CHECK_VERSION(2, 0, 0) (Haihao) Signed-off-by: Ingo Brückl <ib@wupperonline.de> Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>
