* lavc/qsvenc: add tile encoding support for VP9Haihao Xiang2022-01-29

* libavutil/hwcontext_opencl: fix a bug for mapping qsv frame to openclnyanmisaka2022-01-29
| | | | | | | | | | | | | | | mfxHDLPair was added to qsv, so modify qsv->opencl map function as well. Now the following commandline works: ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD128 \ -init_hw_device qsv=qs@va -init_hw_device opencl=ocl@va -filter_hw_device ocl \ -hwaccel qsv -hwaccel_output_format qsv -hwaccel_device qs -c:v h264_qsv \ -i input.264 -vf "hwmap=derive_device=opencl,format=opencl,avgblur_opencl, \ hwmap=derive_device=qsv:reverse=1:extra_hw_frames=32,format=qsv" \ -c:v h264_qsv output.264 Signed-off-by: nyanmisaka <nst799610810@gmail.com> Signed-off-by: Wenbin Chen <wenbin.chen@intel.com>
* libavcodec/vaapi_decode: fix the problem that init_pool_size < nb_surfaceWenbin Chen2022-01-29
| | | | | | | | | | | | | | | | | | | | For vaapi if the init_pool_size is not zero, the pool size is fixed. This means max surfaces is init_pool_size, but when mapping vaapi frame to qsv frame, the init_pool_size < nb_surface. The cause is that vaapi_decode_make_config() config the init_pool_size and it is called twice. The first time is to init frame_context and the second time is to init codec. On the second time the init_pool_size is changed to original value so the init_pool_size is lower than the reall size because pool_size used to initialize frame_context need to plus thread_count and 3 (guarantee 4 base work surfaces). Now add code to make sure init_pool_size is only set once. Now the following commandline works: ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 \ -hwaccel_output_format vaapi -i input.264 \ -vf "hwmap=derive_device=qsv,format=qsv" \ -c:v h264_qsv output.264 Signed-off-by: Wenbin Chen <wenbin.chen@intel.com>
* x86/tx_float: mark AVX2 functions as AVXSLOWLynne2022-01-29
| | | | | | | | | | | | | Makes Bulldozer prefer AVX functions rather than AVX2, which are 64% slower: AVX: 117653 decicycles in av_tx (fft), 1048535 runs, 41 skips AVX2: 193385 decicycles in av_tx (fft), 1048561 runs, 15 skips The only difference between both is that vgatherdpd is used in the former. We don't want to mark them with the new SLOW_GATHER flag however, since gathers are still faster on Haswell/Zen 2/3 than plain loads.
* lavu/tx: do not unconditionally free subcontexts if initialization failsLynne2022-01-29
| | | | | | | | | If a codelet initializes 2 subtransforms, and the second one fails, the failure would free all subcontexts. Instead, if there are subcontexts still left, don't free the array. If all initializations fail, the init() function will return, and reset_ctx() from the previous step will clean up all contained subtransforms.

| | | | | | | | | Fix CID: 1497864 The control flow should return ENOSYS if nb_cd_matches is 0 at before and the ret equal AVERROR(ENOMEM) or goto end label, so remove the last control flow if (ret >= 0) before end label. Signed-off-by: Steven Liu <liuqi05@kuaishou.com>

* x86/tx_float: do not build tx_float_init.c if x86 assembly is disabledLynne2022-01-27
| | | | | | | | This broke builds with --disable-mmx, which also disabled assembly entirely, but ARCH_X86 was still true, so the init file tried to find assembly that didn't exist. Instead of checking for architecture, check if external x86 assembly is enabled.
* avcodec/h264_parse: Move ff_h264_get_profile() to h264_ps.hAndreas Rheinhardt2022-01-26

* avcodec/h264dec: Remove unnecessary headersAndreas Rheinhardt2022-01-26

* lavc/svq3: stop including h264dec.hAnton Khirnov2022-01-26
| | | | | | | The only thing that is actually used directly from there is the PART_NOT_AVAILABLE constant, which can be moved to h264pred.h. Otherwise it only depends on other indirectly included headers.

* lavc/h264_parse: stop including h264dec.hAnton Khirnov2022-01-26
| | | | | | It is unnecessary and only files that are parts of the decoder (as opposed to standalone code called by the decoder) are allowed to include h264dec.h

* lavc/h264dec.h: Move MMCOOpcode to h264_parse.hAnton Khirnov2022-01-26
| | | | | Both parser and decoder use it, so h264_parse is the proper place for it.
* lavc/h264: replace MAX_MMCO_COUNT with H264_MAX_MMCO_COUNTAnton Khirnov2022-01-26
| | | | | | They apparently serve the same purpose; the latter is one larger and has a comment explaining how the value is derived, so seems more trustworthy.

* lavu/tx: add an RDFT implementationLynne2022-01-26
| | | | | | | | | | | | | | | | | | RDFTs are full of conventions that vary between implementations. What I've gone for here is what's most common between both fftw, avcodec's rdft and what we use, the equivalent of which is DFT_R2C for forward and IDFT_C2R for inverse. The other 2 conventions (IDFT_R2C and DFT_C2R) were not used at all in our code, and their names are also not appropriate. If there's a use for either, we can easily add a flag which would just flip the sign on one exptab. For some unknown reason, possibly to allow reusing FFT's exp tables, av_rdft's C2R output is 0.5x lower than what it should be to ensure a proper back-and-forth conversion. This code outputs its real samples at the correct level, which matches FFTW's level, and allows the user to change the level and insert arbitrary multiplies for free by setting the scale option.
* lavu/tx: rewrite internal code as a tree-based codelet constructorLynne2022-01-26
| | | | | | | | | | This commit rewrites the internal transform code into a constructor that stitches transforms (codelets). This allows for transforms to reuse arbitrary parts of other transforms, and allows transforms to be stacked onto one another (such as a full iMDCT using a half-iMDCT which in turn uses an FFT). It also permits for each step to be individually replaced by assembly or a custom implementation (such as an ASIC).
