* fftools: Stop using av_fopen_utf8Martin Storsjö2022-05-23
| | | | | | | | | | Provide a header based inline reimplementation of it. Using av_fopen_utf8 doesn't work outside of the libraries when built with MSVC as shared libraries (in the default configuration, where each DLL gets a separate statically linked CRT).

* 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.

* 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.

| | | | | | | | 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.

* tests/Makefile: Add FRAMECRC variants for filteringAndreas Rheinhardt2022-05-20
| | | | | | | | | | | | | | Lots of tests use the framecrc command together with some filters, so adding a special function for it seems worthwhile. This commit adds one new one and modifies an already existing one: All users of FILTERDEMDEC already use framecrc and the more general FILTERDEMDECENCMUX can be used in scenarios where more control over the used encoders/muxers is needed, so use this in cases where an actual input file is involved. Furthermore, add FILTERFRAMECRC for the cases where no demuxing/decoding occurs, because the input is generated via lavfi. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* tests/Makefile: Remove FILTERDEMDECMUXAndreas Rheinhardt2022-05-20
| | | | | | | | | | | | | | | It is unused and given that one needs an encoder to produce packets from AVFrames (as output by filters) this is likely to remain so, because FILTERDEMDECENCMUX is better for these scenarios. The only case where one can use filters without encoders is with the lavfi input device: It outputs AVPackets which could be copied without another conversion to AVFrames. Yet the variable to check for this is CONFIG_LAVFI_INDEV, but FILTERDEMDECMUX is designed to work with demuxers (i.e. CONFIG_*_DEMUXER). So there is no usecase for FILTERDEMDECMUX.

* 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.

* avformat/hls, dashdec: Don't use AV_OPT flags in av_dict_set()Andreas Rheinhardt2022-05-16
| | | | | | | | | | | | | | | | | av_dict_set() expects a different set of flags, namely the AV_DICT_* flags. Using AV_OPT_FLAG_DECODING_PARAM (or any AV_OPT_FLAG_*) ic av_dict_set() is therefore completely wrong and given that av_dict_set() just doesn't care about whether the string it receives has anything to do with a decoding parameter or not, it should just be removed without replacement. (The numerical value of AV_OPT_FLAG_DECODING_PARAM currently coincides with AV_DICT_IGNORE_SUFFIX. Given that the dictionaries we are dealing with here are always empty (i.e. NULL) before the calls to av_dict_set(), this flag changes nothing. It would be different if it were equal to one of the AV_DICT_DONT_STRDUP_* values.) Reviewed-by: Jan Ekström <jeebjp@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
