2020-12-03vp9/vic: Resolve pessimizing movesLioncash1-10/+10
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 applicableLioncash1-1/+1
Prevents bugs from occurring where the results of a function are accidentally discarded
2020-10-30vp9: Mark functions with [[nodiscard]] where applicableLioncash1-4/+4
Prevents values from mistakenly being discarded in cases where it's a bug to do so.
2020-10-30vp9: Make some member functions internally linkedLioncash1-48/+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.
2020-10-27vp9: std::move buffer within ComposeFrameHeader()Lioncash1-1/+1
We can move the buffer here to avoid a heap reallocation

2020-10-27video_core: NVDEC Implementationameerj1-0/+1010
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>
