* Initial NVDEC and VIC implementation * Update FFmpeg.AutoGen to 4.3.0 * Add nvdec dependencies for Windows * Unify some VP9 structures * Rename VP9 structure fields * Improvements to Video API * XML docs for Common.Memory * Remove now unused or redundant overloads from MemoryAccessor * NVDEC UV surface read/write scalar paths * Add FIXME comments about hacky things/stuff that will need to be fixed in the future * Cleaned up VP9 memory allocation * Remove some debug logs * Rename some VP9 structs * Remove unused struct * No need to compile Ryujinx.Graphics.Host1x with unsafe anymore * Name AsyncWorkQueue threads to make debugging easier * Make Vp9PictureInfo a ref struct * LayoutConverter no longer needs the depth argument (broken by rebase) * Pooling of VP9 buffers, plus fix a memory leak on VP9 * Really wish VS could rename projects properly... * Address feedback * Remove using * Catch OperationCanceledException * Add licensing informations * Add THIRDPARTY.md to release too Co-authored-by: Thog <me@thog.eu>
