[FFmpeg-user] Sending ffmpeg output to virtual usb uvc device in Linux

[Jim Ruxton]

I am wondering if there is a way to send ffmpeg output of a stream to a 
virtual usb device. I am using a videoloopback device now. I thought I 
could use something like this https://github.com/wlhe/uvc-gadget to be 
able to convert the dummy video device to make it look like a webcam but 
I haven't had any luck. One of the programs I'm using won't work with a 
stream and seems to need a usb device though most programs work with the 
loopback device as is. The ffmpeg command I am currently using is:

ffmpeg -re -i $(youtube-dl -g -f 95 
https://www.youtube.com/watch?v=9Auq9mYxFEE) -vcodec rawvideo -f v4l2 
/dev/video2 -f alsa default

Thanks for any tips or thoughts on this.
