Hardware Scroll Buttons

rlsten

Would it be possible to program hardware buttons to emulate the scroll up and scroll down software buttons on the library page. The code for the software buttons is located in /srv/assets/js/runeui.js and runeui.min.js; my question is how does one call that code in a python script, such as was used for a hardware play/pause button here: #366514. Specifically, what would I substitute for this line in the hardware play/pause script:

subprocess.call("mpc toggle", shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

Thanks!

Hi rlsten,

This is not possible the easy way.
The javascript code runs on the client side (browser) and not on the server.
This is also true when using a local browser on an attached display.

Play, pause, next and volume control are handled by mpd (music player daemon) that runs on the server.
Mpd reports these changes to the client via WebSocket connections which are processed within the javascript code.

If it is meant for the local browser option, I would try to emulate the up and down arrow keys.

Thanks very much, Frank. I will try to emulate the up and down keys.
