Feature request - Spout capture

[frtog]

Hello,

I would like to file a feature request for being able to use Spout (​https://spout.zeal.co/) as an input device to ffmpeg.

Similarly to libavdevice/dshow.c or libavdevice/x11grab.c

This would allow recording real time Spout senders’ video to file in the most resource efficient manner and leverage all the nice features of ffmpeg.

There are a few alternatives that I have personally tried and could share here. But none allow efficient and error free recording of 4K 60 fps video.

Sorry if this is not the right place to file such a feature request.
