Previous to this commit, the tests were using operator[] from
unordered_map to query elements but this silently inserts empty elements
when they don't exist. If all threads were executed without concurrency,
this wouldn't be an issue, but the same unordered_map could be written
from two threads at the same time. This is a data race and makes some
previously inserted elements invisible for a short period of time,
causing them to insert and return an empty element. This default
constructed element (a zero) was used to index an array of fibers that
asserted when one of them was nullptr, shutting the test session off.
To address this issue, lock on thread id reads and writes. This could be
a shared mutex to allow concurrent reads, but the definition of
std::this_thread::get_id is fuzzy when using non-standard techniques
like fibers. I opted to use a standard mutex.
While we are at it, fix the included headers.
* A regression was in 39c8d18 and token verification function was
broken.
* The reason being `httplib` now requires OpenSSL 1.1+ API while
LibreSSL 2.x provided OpenSSL 1.0 compatible API.
* The bundled LibreSSL has been updated to 3.2.2 so it now provides
OpenSSL 1.1 compatible API now.
* Also the path hint has been added so that it will find the correct
path to the CA certs on *nix systems.
* An option is provided so that *nix system distributions/providers can
use their own SSL implementations when compiling Yuzu/Citra to
(hopefully) complies with their maintenance guidelines.
* LURLParse is also removed since `httplib` can handle
`scheme:host:port` string itself now.
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.
