Say I ramify a video stream to 2 ffplay processes
cat video.mp4 | tee >(ffplay -i -) >(ffplay -i -) > /dev/null
Now, if I kill one of the ffplay process, the stream is stopped which is not what I want.
How can I modify this command to continue to stream the video to the first ffplay process if the second is killed?
PS: I am looking for a solution without named pipe (fifo)
A solution
cat video.mp4 | tee >(ffplay -i - || cat >/dev/null ) >(ffplay -i - || cat >/dev/null) > /dev/null
Example: to save an encrypted webcam capture and play it at the same time with possible killing of the file saving process (openssl) or the player (ffplay), I can use:
ffmpeg -f alsa -ac 2 -i plughw:0,0 -f video4linux2 -s vga -i /dev/video0 -f ogg - | tee >(openssl enc -k mypassword -aes-256-cbc > encrypted-capture.aes-256-cbc || cat >/dev/null) >(ffplay -fs -i - || cat >/dev/null) > /dev/null
You have to kill the ffplay process ( press f and then run pkill ffplay), not close the window with Esc
