Michael Fabian 'Xaymar' Dirks cbd75767fa encoders/ffmpeg: Implement AMF H.264 and H.265 handlers
Adds support for the AMD Advanced Media Framework H.264 and H.265 encoders via FFmpeg. The majority of settings are supported, and the UI/UX experience mimics that of the NVENC implementation. Various settings are left out due to their complexity and should be controlled via the custom parameters field.
