Philip Langdale	13168ecbdc	avfilter/vf_scale_cuda: Simplify output plane addressing I'm not sure why this was written the way it was originally. We initialise the plane addresses correctly in hwcontext_cuda so why try and play games to calculate the plane offsets directly in this code?	6 years ago
Philip Langdale	bfbde996cf	avfilter/vf_scale_cuda: Add support for YUV444P16 This format is interesting because it's what you get for decoded 10/12bit HEVC 4:4:4.	6 years ago
Philip Langdale	89bd7554b2	avfilter/vf_scale_cuda: Fix incorrect scaling of > 8bit content When i converted the filter to use texture objects instead of texture references, I incorrect dropped the `pixel_size` scaling factor when setting `pitchInBytes`. `src_pitch` is in pixels and so must be scaled up.	6 years ago
Lynne	b79b29ddb1	libavutil: add an FFT & MDCT implementation This commit adds a new API to libavutil to allow for arbitrary transformations on various types of data. This is a partly new implementation, with the power of two transforms taken from libavcodec/fft_template, the 5 and 15-point FFT taken from mdct15, while the 3-point FFT was written from scratch. The (i)mdct folding code is taken from mdct15 as well, as the mdct_template code was somewhat old, messy and not easy to separate. A notable feature of this implementation is that it allows for 3xM and 5xM based transforms, where M is a power of two, e.g. 384, 640, 768, 1280, etc. AC-4 uses 3xM transforms while Siren uses 5xM transforms, so the code will allow for decoding of such streams. A non-exaustive list of supported sizes: 4, 8, 12, 16, 20, 24, 32, 40, 48, 60, 64, 80, 96, 120, 128, 160, 192, 240, 256, 320, 384, 480, 512, 640, 768, 960, 1024, 1280, 1536, 1920, 2048, 2560... The API was designed such that it allows for not only 1D transforms but also 2D transforms of certain block sizes. This was partly on accident as the stride argument is required for Opus MDCTs, but can be used in the context of a 2D transform as well. Also, various data types would be implemented eventually as well, such as "double" and "int32_t". Some performance comparisons with libfftw3f (SIMD disabled for both): 120: 22353 decicycles in fftwf_execute, 1024 runs, 0 skips 21836 decicycles in compound_fft_15x8, 1024 runs, 0 skips 128: 22003 decicycles in fftwf_execute, 1024 runs, 0 skips 23132 decicycles in monolithic_fft_ptwo, 1024 runs, 0 skips 384: 75939 decicycles in fftwf_execute, 1024 runs, 0 skips 73973 decicycles in compound_fft_3x128, 1024 runs, 0 skips 640: 104354 decicycles in fftwf_execute, 1024 runs, 0 skips 149518 decicycles in compound_fft_5x128, 1024 runs, 0 skips 768: 109323 decicycles in fftwf_execute, 1024 runs, 0 skips 164096 decicycles in compound_fft_3x256, 1024 runs, 0 skips 960: 186210 decicycles in fftwf_execute, 1024 runs, 0 skips 215256 decicycles in compound_fft_15x64, 1024 runs, 0 skips 1024: 163464 decicycles in fftwf_execute, 1024 runs, 0 skips 199686 decicycles in monolithic_fft_ptwo, 1024 runs, 0 skips With SIMD we should be faster than fftw for 15xM transforms as our fft15 SIMD is around 2x faster than theirs, even if our ptwo SIMD is slightly slower. The goal is to remove the libavcodec/mdct15 code and deprecate the libavcodec/avfft interface once aarch64 and x86 SIMD code has been ported. New code throughout the project should use this API. The implementation passes fate when used in Opus, AAC and Vorbis, and the output is identical with ATRAC9 as well.	6 years ago

Adam Richter	b8ed493061	libswcale: Fix possible string overflow in test. In libswcale/tests/swcale.c, the function fileTest() calls sscanf in an argument of "%12s" on character srcStr[] and dstStr[], which are only 12 bytes. So, if the input string is 12 characters, a terminating null byte can be written past the end of these arrays. This bug was found by cppcheck.

Philip Langdale	4fa4f1d7a9	swscale: Add test for isSemiPlanarYUV to pixdesc_query Lauri had asked me what the semi planar formats were and that reminded me that we could add it to pixdesc_query so we know exactly what the list is.	6 years ago
Philip Langdale	cd48318035	swscale: Add support for NV24 and NV42 The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.	6 years ago
Philip Langdale	5de4f1d871	avutil: Add NV24 and NV42 pixel formats These are the 4:4:4 variants of the semi-planar NV12/NV21 formats. These formats are not used much, so we've never had a reason to add them until now. VDPAU recently added support HEVC 4:4:4 content and when you use the OpenGL interop, the returned surfaces are in NV24 format, so we need the pixel format for media players, even if there's no direct use within ffmpeg. Separately, there are apparently webcams that use NV24, but I've never seen one.	6 years ago
