GPU decoding seems to be more picky when it comes to the maximum number of reference frames.
2021-08-16configure_graphics: Add GPU nvdec decoding as an optionameerj
Some system configurations may see visual regressions or lower performance using GPU decoding compared to CPU decoding. This setting provides the option for users to specify their decoding preference. Co-Authored-By: yzct12345 <87620833+yzct12345@users.noreply.github.com>

Silences a sws_scale runtime warning about unaligned strides.
2021-08-08vp9: Ensure the first frame is completeameerj
Silences a runtime error due to the first frame missing the frame data, and being set to hidden despite being a key-frame.

nvdec: Fix VP9 reference frame refreshes
2021-08-06vp9: Cleanup unused variablesameerj
With reference frames refreshes fix, we no longer need to buffer two frames in advance. We can also remove other unused or otherwise unneeded variables.

2021-02-13video_core: Reimplement the buffer cacheReinUsesLisp
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.

2020-12-30video_core: Rewrite the texture cacheReinUsesLisp
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 messagesLioncash
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.2Lioncash
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_framesLioncash
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.

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.

Removes the usage of moves that don't result in behavior different from a copy, or otherwise would prevent copy elision from occurring.

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.
