I'm guessing this uses underlying FFmpeg CUDA support.
It's a bit more complicated than this as ffmpeg doesn't have GPU support
for audio processing.
So we took the Opus codec, ported it to CUDA, heavily modified it for
parallel execution, and combined it with some other codecs (G.711 for
now) to be able to do transcoding on a GPU.
This isn't relevant for the regular media proxy (RTP passthrough) use
case though.
Cheers
