  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

  • 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)
