Yeah, I noticed that shortly after.
Never before thought to run ffmpeg.c without any inputs, but as long as
you stick to -filter_complex instead of plain -filter, it works great.
But this device is not meant for ffmpeg.c alone.
It has been explained time and again that libavdevice is useful for
users of applications that are designed to expect a demuxer, to make
them use something more exotic than a demuxer.
I never doubted that, though in my case writing the input as a filter
makes a ton more sense, cause filters are a lot better integrated with
the whole hwaccel framework.
With this patch applied, it works via lavfi.c, but you have no control
over the created hwdevice context.
