Pranav, Motion doesn't deal with vloopback at all! This is a standalone application, that only duplicates the raw content from one video device into several independent ones. So, it actually does exactly what you want. :-) Brgds Joerg. -- Pranav Tipnis wrote: Thanks Steven for your suggesstion. I created two virtual video devices "/dev/video1" and "/dev/video2" in addition to original device "/dev/video0" using v4l2 loopback driver. But I think the output from motion on /dev/video2 will be in JPEG format. Is this understanding correct? Actually, I want output from motion in raw format so that ffmpeg can encode it to h264 or mpeg4. Is this possible?
