What's Changed
- Multi-threaded decode. In previous versions the final steps of decoding a frame would only be started when vaExportSurfaceHandle was called. This wasn't correct, and only worked because ffmpeg based applications (such as Firefox) call it every frame, however that isn't required by VA-API. This change moves the final steps to a separate thread that begins when vaEndPicture is called.
- Reworked GPU selection. We now use the the passed-in DRM fd to attempt to select the correct GPU to use. This can be overridden with the
NVD_GPUenvironment variable which you can set to the id of the GPU you want to use. You can use thenvidia-smitool to find the id. - Added option to limit the maximum instances per process using the
NVD_MAX_INSTANCESenvironment variable. This setting limits how many concurrent contexts are allow, which can limit the amount of memory that's used. Useful for GPUs with limited VRAM on video heavy websites. - Added missing libva dependency to build, and set the minimum required version to 2.8.0.
- Set EGL_SUPPORT_REUSE_NV to false when creating the EGLStream. This prevents NVIDIA's EGL library from buffering one of the frames, which could lead to the driver leaking that frame.
