Please read conditions below carefully, and don't delete this part. Invalid issues will be closed.

• No apps related to piracy or intellectual property infringement is allowed.
• We can't guarantee if the app will be developed by anyone.
• We encourage you to develop the app by yourself. This would be a great contribution to webOS homebrew community.

• I understand conditions above
• (Optional) I'd like to develop this app by myself

Issue content starts below this line

---It would be great to have an app that you could list, or select from a list of apps, that while running in the foreground, the LG screensaver would be prevented from coming on.

I could provide info from the LGC1 if needed to support.

I would love to assist but almost no programming skills but mediocre System Administration skills.

Thank you for this suggestion. This is a good one.

Done some researches about this. I don't have enough time to do this, but should be helpful for application developers wants to prevent their apps from sleeping:

For SDL applications

Use SDL_DisableScreenSaver and SDL_EnableScreenSaver.

For other applications (like webapps)

You can register on this Luna URI:

luna://com.webos.service.tvpower/power/registerScreenSaverRequest

with params

{
  "subscribe": true,
  "clientName": "AnyValue"
}

When screensaver is about to start, you will receive following message:

{
  "returnValue": true,
  "timestamp": "1388518297",
  "state": "Active",
  "instantBoot": "on"
}

Send message to this URI:

luna://com.webos.service.tvpower/power/responseScreenSaverRequest

with params

{
  "clientName": "AnyValue",
  "ack": false,
  "timestamp": "1388518297"
}

Does anyone know if this still works? We had it working, but now it looks like we don't get a callback

@SuneKjaergaard I think it still works. I'm still using that in my SDL port: https://github.com/webosbrew/SDL-webOS/blob/b18d7026e20bb5422f4b87910c586cbb0ecabd82/src/core/webos/SDL_webos_init.c#L230
