Hi! I am attempting to use this with my PCDuino to run Octoprint. I am having an issue with getting the mjpg-streamer to start. When I type in sudo /etc/init.d/mjpg-streamer start I get the error /etc/init.d/mjpg-streamer: 13: /etc/default/mjpg-streamer: /home/ubuntu/mjpg-streamer/mjpg-streamer-experimental/input_uvc.so -y: not found mjpg-streamer loads as I have it displaying the details of the output:

MJPG Streamer Version: svn rev: exported o: www-folder-path...: disabled o: HTTP TCP port.....: 8080 o: username:password.: disabled o: commands..........: enabled

I have changed the /default/ file to have the user ubuntu DAEMON_HOME to where it is on my setup. I also had to remove the single quotes from the DAEMON_HOME.

I don't know how to get an init.d file to display the command it is executing so I am not sure if it is calling it write. Do you have any suggestions? It seems as if it is a parsing error with the arguments.

Thanks :)

I needed to change the quotes in the default file DAEMON_ARGS line to get this to work i.e.:

DAEMON_ARGS="-i $DAEMON_HOME/input_uvc.so -r SXGA -f 15 -o $DAEMON_HOME/output_http.so" # UVC-mode
# DAEMON_ARGS="-i $DAEMON_HOME/input_uvc.so -y -o $DAEMON_HOME/output_http.so" # YUV-mode
