Open Program from Python script

[thejason40]

Hi guys, hoping someone can help. I'm probably going about this all wrong but I'm trying to create a button on my TV remote that will open Kodi with one click. I've been trying to do this by modifying this script: https://github.com/dillbyrne/es-cec-input.

I've edited, and added to, the block from lines 173 & 174, so it now reads:

elif "exit" in line:
            device.emit_click(keylist[1])

elif "green" in line:
            Kodi = subprocess.Popen("/home/pi/RetroPie/roms/ports/Kodi.sh")

but it just won't work while I'm in EmulationStation. Like I said, I'm probably way off the mark here, but if anyone has any ideas, it'd be appreciated.

Kodi probably doesn't like that Emulationstation is started and has control of the screen - try exiting Emulationstation first, then start Kodi.

@mitu What happens when you load a rom from the ES menu? It is suspended and then resumed somehow (as it loads back up in the same place you left it)?

[mitu]

The 'suspend & resume' is triggered internally by Emulationstation, when it starts the emulator/game, it's not accessible externally.

@mitu Ah, that scuppers those plans then. I think I'll give this up as a failed experiment. I did manage to get Kodi to launch from my green button by importing psutil and check_output and changing the code to

espid = int(check_output(["pidof","-s","emulationstation"])) 
es = psutil.Process(espid)
es.suspend()
Kodi = subprocess.Popen("/home/pi/RetroPie/roms/ports/Kodi.sh")
Kodi.wait
es.resume()

But then the script would no longer start from my crontab on boot so not really usable.
