Comment (by oromit):
Looking at the code in ffmpeg.c, it looks like it only supports one single
-hwaccel per input stream. They do more than "only initialize the gpu
libraries", in fact, that's one thing they don't really do at all.
The hwupload filter chooses what hardware to use based on the type of
hw_device_ctx set on its context.
I don't think this is possible without massive rewrites of ffmpeg.c.
In a custom application using the ffmpeg API it should be relatively
straight forward.
