While it might not be possible to support in a proper way, and the FFmpeg multithreading is probably useless in the context of this library, but I think this is not generally true.
Most hardware decoders need a good bit of parsing, and for some in combination with high-bitrate content it is enough that multithreading can be useful due to allowing to use two CPUs at low frequencies instead of having to clock one significantly higher.
