Feature: Prevent host sleep while encoding on nodes

[PilaScat]

Is your feature request related to a problem? Please describe.
Currently, when a Tdarr node is performing an encoding session, the host system may enter sleep or suspend mode, interrupting the ongoing process.

Describe the solution you'd like
It would be helpful to implement a feature that, during an active encoding session, prevents the host from going into sleep or standby. I suggest adding a configurable option for nodes to keep the host awake as long as there are active encoding processes.

Describe alternatives you've considered

Having a cross-platform solution for this is a bit of a hacky business and personally I'm not a fan of applications tweaking OS settings like this.

Would it not make more sense just to adjust your OS settings to prevent sleep if you're doing a lot of transcoding?

Lets say you have multiple applications all adjusting the OS sleep settings - it's easy to get into a messy situation whereby one application is saying "OS should not sleep" but then another application updates OS settings to say "OS can now sleep", overwriting the other application's OS updates, causing the host to sleep.

Also it's not possible to do this if Tdarr is running in a container.

If there's a simple way to do what you're after then can add it in, but I suppose there haven't been many requests for this as Tdarr is typically on servers that run 24/7.

First I'll report here this feature that is probably more important:

Automatic retry and queue re-add: If a node fails unexpectedly (such as due to sleep or a power outage), automatically retry the transcode and re-add the job to the queue so another node can pick it up.

I'm talking only for Windows really, as I have different home PCs capable of transcoding, I don't know the tdarr programming language but should be easy for Windows, here the docs for this feature, this is what multimedia apps use.

I believe the OS chooses automatically when to go to sleep, that is, when no one requests to stay awake.

Yes but I can't keep all the PCs always on, it was to intercept when they were on and exploit them, since their GPU never does anything, you could even think of a wake on lan but this is a much more complex thing and would probably be very niche

Have you looked at MS PowerTools Awake >?
works fantastic, can set per interval, or indefinitly to keep awake on windows..

I know it, but keeping it awake is not a problem
