codec: Fix GPU decoder detection on Windows and a memory leak

2022-03-21codec: Disable HW_FRAMES method check on Windowsameerj
It was reported that this method causes crashes on certain Linux decoding backends, hence the check to avoid it. This subsequently caused Windows GPU decoders to never be selected and always fall back to CPU decoding, disable the check on Windows for now.

... this would resolve some edge-cases where multiple devices are present and ffmpeg is unable to auto-supply the hw surfaces

* skip impersonated VAAPI implementaions ("imposter detection") * place VAAPI priority below CUDA/NVDEC/CUVID

2021-11-24video_core/codecs: fix multiple decoding issues on Linux ...liushuyu
* when someone installed Intel video drivers on an AMD system, the decoder will select the Intel VA-API decoding driver and yuzu will crash due to incorrect driver selection; the fix will check if the currently about-to-use driver is loaded in the kernel * when using NVIDIA driver on Linux with a ffmpeg that does not have CUDA capability enabled, the decoder will crash; the fix simply making the decoder prefers the VDPAU driver over CUDA on Linux
2021-11-12codes: Rename ComposeFrameHeader to ComposeFrameameerj
These functions were composing the entire frame, not just the headers. Rename to more accurately describe them.

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>

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.
2020-12-04codec: 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.

2020-10-26video_core: NVDEC Implementationameerj
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>
