Thank you! It does indeed work. I only had to add a format conversion at 
the end, because sdl2 doesn't support gray.

ffmpeg -f dshow -video_size 1280x800 -framerate 10 -pixel_format rgb8 -i 
video="ASI178MM Camera (ZWO Design)" -map 0 -c copy -f rawvideo pipe:1 | 
ffmpeg -f rawvideo -video_size 1280x800 -framerate 10 -pixel_format gray 
-i pipe:0 -vf format=rgb24 -f sdl2 -
