Some help is needed on the following:
I would like to fork feh as a slideshow in the background and still be able to sent some keys to it (eg. 'n' for next picture or 'q' to quit).
So I created a pipe: mkfifo /tmp/cmdVideo
I exported DISPLAY=:0
and start: feh -Z -z -F -d -D10 -f /home/pi/newapp/AlleFotos </tmp/cmdVideo &
Via another shell I sent characters into the pipe:
To actually start feh: echo -n . > /tmp/cmdVideo
After that it starts showing pictures.
All my other characters don't arrive at feh. Eg.:
echo -n 'n' > /tmp/cmdVideo
echo -n 'q' > /tmp/cmdVideo
Feh just goes on showing pictures.
I have also tried to move the location of the '</tmp/cmdVideo' within the commandline but that did not help.
Obviously I am making a mistake here. Can someone help me in how to set this up correctly?
The same setup works fine for omxplayer .
Thanks in advance!
