2021-02-13video_core: Reimplement the buffer cacheReinUsesLisp1-3/+0
Reimplement the buffer cache using cached bindings and page level granularity for modification tracking. This also drops the usage of shared pointers and virtual functions from the cache. - Bindings are cached, allowing to skip work when the game changes few bits between draws. - OpenGL Assembly shaders no longer copy when a region has been modified from the GPU to emulate constant buffers, instead GL_EXT_memory_object is used to alias sub-buffers within the same allocation. - OpenGL Assembly shaders stream constant buffer data using glProgramBufferParametersIuivNV, from NV_parameter_buffer_object. In theory this should save one hash table resolve inside the driver compared to glBufferSubData. - A new OpenGL stream buffer is implemented based on fences for drivers that are not Nvidia's proprietary, due to their low performance on partial glBufferSubData calls synchronized with 3D rendering (that some games use a lot). - Most optimizations are shared between APIs now, allowing Vulkan to cache more bindings than before, skipping unnecesarry work. This commit adds the necessary infrastructure to use Vulkan object from OpenGL. Overall, it improves performance and fixes some bugs present on the old cache. There are still some edge cases hit by some games that harm performance on some vendors, this are planned to be fixed in later commits.

2021-02-05CMake: Implement YUZU_USE_BUNDLED_FFMPEGlat9nq1-1/+1
For Linux, instructs CMake to use the FFmpeg submodule in externals. This is HEAVILY based on our usage of the late Unicorn. Minimal change to MSVC as it uses the yuzu-emu/ext-windows-bin. MinGW now targets the same ext-windows-bin libraries as MSVC for FFmpeg. Adds FFMPEG_LIBRARIES to WIN32 and simplifies video_core/CMakeLists.txt a bit.

2020-12-30video_core: Rewrite the texture cacheReinUsesLisp1-4/+4
The current texture cache has several points that hurt maintainability and performance. It's easy to break unrelated parts of the cache when doing minor changes. The cache can easily forget valuable information about the cached textures by CPU writes or simply by its normal usage.The current texture cache has several points that hurt maintainability and performance. It's easy to break unrelated parts of the cache when doing minor changes. The cache can easily forget valuable information about the cached textures by CPU writes or simply by its normal usage. This commit aims to address those issues.
2020-12-07video_core: Remove unnecessary enum class casting in logging messagesLioncash2-3/+3
fmt now automatically prints the numeric value of an enum class member by default, so we don't need to use casts any more. Reduces the line noise a bit.
2020-12-05video_core: Resolve more variable shadowing scenarios pt.2Lioncash1-20/+20
Migrates the video core code closer to enabling variable shadowing warnings as errors. This primarily sorts out shadowing occurrences within the Vulkan code.
2020-12-04codec: Remove deprecated usage of AVCodecContext::refcounted_framesLioncash1-1/+0
This was only necessary for use with the avcodec_decode_video2/avcoded_decode_audio4 APIs which are also deprecated. Given we use avcodec_send_packet/avcodec_receive_frame, this isn't necessary, this is even indicated directly within the FFmpeg API changes document here on 2017-09-26: https://github.com/FFmpeg/FFmpeg/blob/master/doc/APIchanges#L410 This prevents our code from breaking whenever we update to a newer version of FFmpeg in the future if they ever decide to fully remove this API member.
2020-12-04video_core: Resolve more variable shadowing scenariosLioncash2-2/+2
Resolves variable shadowing scenarios up to the end of the OpenGL code to make it nicer to review. The rest will be resolved in a following commit.
2020-12-03vp9/vic: Resolve pessimizing movesLioncash2-11/+11
Removes the usage of moves that don't result in behavior different from a copy, or otherwise would prevent copy elision from occurring.

2020-11-02nvdec: Make use of [[nodiscard]] where applicableLioncash7-16/+16
Prevents bugs from occurring where the results of a function are accidentally discarded
2020-10-30vp9: Be explicit with copy and move operatorsLioncash1-0/+18
It's deprecated in the language to autogenerate these if the destructor for a type is specified, so we can explicitly specify how we want these to be generated.
2020-10-30vp9: Mark functions with [[nodiscard]] where applicableLioncash2-13/+13
Prevents values from mistakenly being discarded in cases where it's a bug to do so.
2020-10-30vp9: Provide a default initializer for "hidden" memberLioncash1-1/+1
The API of VP9 exposes a WasFrameHidden() function which accesses this member. Given the constructor previously didn't initialize this member, it's a potential vector for an uninitialized read. Instead, we can initialize this to a deterministic value to prevent that from occurring.
2020-10-30vp9: Make some member functions internally linkedLioncash2-58/+54
These helper functions don't directly modify any member state and can be hidden from view.
2020-10-28video_core: Enforce -Wredundant-move and -Wpessimizing-moveReinUsesLisp1-1/+1
Silence three warnings and make them errors to avoid introducing more in the future.
2020-10-28video_core: Enforce -Werror=type-limitsReinUsesLisp1-1/+1
Silences one warning and avoids introducing more in the future.

2020-10-27video_core: NVDEC Implementationameerj16-0/+2857
This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library. The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data. To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library. Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header. Async GPU is not properly implemented at the moment. Co-Authored-By: David <25727384+ogniK5377@users.noreply.github.com>
