The FFmpeg backend is a software emulated video encoder device backend. It can be used for testing, for developing guest kernel changes and more. The backend roughly mirrors how the FFmpeg decoder backend is implemented right now, with the notable difference that it does not use swscale as the de-facto input format is NV12 or YUV420 and the guest can likely provide buffers in that format. BUG=b:239897269 TEST=See testing instructions in the updated book document.
