How to specify "Device" or "Fifo" in YUV video output?

[OleJak]

I am reading doks for VLC Command line programing. There I saw


YUV video output

--yuv-file=<string> device, fifo or filename

device, fifo or filename to write yuv frames too.


What heare does device and fifo mean? how to specify them?

FIFO is just another name for named pipe. You need to give the path to a regular file, a named pipe or a device node.
