* nvdec: Make use of [[nodiscard]] where applicableLioncash2020-11-027-16/+16
| | | | | Prevents bugs from occurring where the results of a function are accidentally discarded
* vp9: Be explicit with copy and move operatorsLioncash2020-10-301-0/+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.
* vp9: Mark functions with [[nodiscard]] where applicableLioncash2020-10-302-13/+13
| | | | | Prevents values from mistakenly being discarded in cases where it's a bug to do so.
* vp9: Provide a default initializer for "hidden" memberLioncash2020-10-301-1/+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.
* vp9: Make some member functions internally linkedLioncash2020-10-302-58/+54
| | | | | These helper functions don't directly modify any member state and can be hidden from view.

| | | | | | | | We can move the buffer here to avoid a heap reallocation

* video_core: NVDEC Implementationameerj2020-10-2716-0/+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>
