  • Why does ffplay read both video and keyboard input from stdin ?

    27 janvier 2016, par cxrodgers

    I’m trying to compress a video feed from a webcam while simultaneously displaying it, using ffmpeg and ffplay. I do actually have this working, but I want to disable the ffplay window from interpreting keyboard presses.

    It took me a while to figure this out but here’s what I’m using :

    ffmpeg -f video4linux2 -i /dev/video0 -vcodec mpeg4 -f rawvideo - \
    
  | tee output.mkv \
    
  | ffplay -fflags nobuffer -

    (Actually I am doing all of this from a Python script using the subprocess module. Here I have represented it as a straightforward terminal command because the result is the same.)

    So this actually works and does everything I want. The only thing is that if the ffplay window is active, it interprets keypresses (like "F" for fullscreen). Instead I want it to completely ignore all keypresses.

    My questions :

    1. How is this even possible ? I thought I was redirecting video input to stdin, and then telling ffplay to read video from stdin. How can keypresses be multiplexed on the same pipe ?
    2. How can I disable this behavior ? I tried "-nostdin" but it doesn’t work with my version.

    # ffplay -nostdin output.mkv

    ffplay version N-77455-g4707497 Copyright
    (c) 2003-2015 the FFmpeg developers built with gcc 4.8 (Ubuntu
    4.8.4-2ubuntu1 14.04)
