I have a local video and I want to stream it to a dummy webcam video device from
v4l2loopback. I created the dummy device at
/dev/video1. How to use
ffmpeg to steam that local video
trial_video.mp4 to the dummy device?
Based on this AU Q&A titled: Is there any way ffmpeg send video to /dev/video0 on Ubuntu? you can do the following:
$ ffmpeg -re -i trial_video.mp4 -map 0:v -f v4l2 /dev/video1
