You could try for example: mkfifo /tmp/livestmp/stream.yuv ffplay <tvcard> -vo yuv4m /tmp/livestmp/stream.yuv Then open yuv4mpeg stream in LiVES. Adjust the parameters and paths to suit your system. I hope in the next few weeks/months I will have a chance to add v4l input to LiVES which will connect directly to the camera/card.
