ffv1enc: add a Vulkan encoder This commit implements a standard, compliant, version 3 and version 4 FFv1 encoder, entirely in Vulkan. The encoder is written in standard GLSL and requires a Vulkan 1.3 supporting GPU with the BDA extension. The encoder can use any amount of slices, but nominally, should use 32x32 slices (1024 in total) to maximize parallelism. All features are supported, as well as all pixel formats. This includes: - Rice - Range coding with a custom quantization table - PCM encoding CRC calculation is also massively parallelized on the GPU. Encoding of unaligned dimensions on subsampled data requires version 4, or requires oversizing the image to 64-pixel alignment and cropping out the padding via container flags. Performance-wise, this makes 1080p real-time screen capture possible at 60fps on even modest GPUs.

ffv1: add a Vulkan-based decoder This patch adds a fully-featured level 3 and 4 decoder for FFv1, supporting Golomb and all Range coding variants, all pixel formats, and all features, except for the newly added floating-point formats. On a 6000 Ada, for 3840x2160 bgr0 content at 50Mbps (standard desktop recording), it is able to do 400fps. An Alder Lake with 24 threads can barely do 100fps.

lavc: add a ProRes RAW Vulkan hwaccel This commit adds a ProRes RAW hardware implementation written in Vulkan. Both version 0 and version 1 streams are supported. The implementation is highly parallelized, with 512 invocations dispatched per every tile, with generally 4k tiles on a 5.8k stream. Thanks to unlord for the 8-point iDCT. Benchmark for a generic 5.8k RAW HQ file: 6900XT: 63fps 7900XTX: 84fps 6000 Ada: 120fps Intel: 9fps

vulkan_prores: generate SPIR-V at compile-time

lavc: add a ProRes Vulkan hwaccel Add a shader-based Apple ProRes decoder. It supports all codec features for profiles up to the 4444 XQ profile, ie.: - 4:2:2 and 4:4:4 chroma subsampling - 10- and 12-bit component depth - Interlacing - Alpha The implementation consists in two shaders: the VLD kernel does entropy decoding for color/alpha, and the IDCT kernel performs the inverse transform on color components. Benchmarks for a 4k yuv422p10 sample: - AMD Radeon 6700XT: 178 fps - Intel i7 Tiger Lake: 37 fps - NVidia Orin Nano: 70 fps
