Batch file for live TV

[fla]

Are there batch files like ParallelProcessing.bat PostProcessing.bat PostCancel.bat for Live TV (or a config.xml setting to get those to be called for live TV)? I want to prevent hibernation when Live TV starts and re-enable it minutes (not milliseconds) after Live TV stops. I had the NextPVR server hibernate on a kodi reminder automatic channel change today.

Sorry, no there isnt.

Understandable, it's kind of an uncommon user request. Thanks for the reply

Ultimately, it shouldn’t go to sleep while you’re streaming anyway.

I'd be curious to see the NextPVR logs for this.

I think Martin in this thread understood what is happening. The server does stay awake during streaming live TV due to the powercfg request made by NextPVRServer.exe. During a channel change (briefly not streaming) the powercfg request must be cleared and setup again for the next channel. On a fast enough PC, that window of opportunity can be enough for the sleep/hibernate to trigger before the 2nd channel begins to stream.

Using kodi reminder automatic channel change, the window of opportunity is short enough that it stays awake 19 times out of 20.

I understand what is happening too, but I would still like to see the logs. I can think of one situation where I think there might be a flaw, at least looking at my Linux logs

Sorry I didn't see this post. I'll try to get some logs.

To reproduce, play live TV remotely in kodi for longer than your server's sleep timeout and then press stop. Wait for a few seconds for the server to sleep (actually hibernate in my setup to save more power). Play another live TV channel in kodi. It doesn't work because the server is sleeping.

BTW the feature in the nextPVR kodi addon that wakes up the server on kodi startup like X-NEWA used to do is cool!

There might be a difference in how sub handles hibernate vs hybrid too. I don't know how much power you actually save in hibernate anymore.

The power management in pvr.nextpvr is better, it can send a WOL when you resume the client from sleep too. In a pinch if you didn't want to walk to the PC, you could sleep the client and see what happens.

Attached the full log file. Here are the highlights (all live TV from kodi):

1. Play one channel at 19:22
   
2. Play a second channel at 19:33 without pressing stop
   
3. Use a kodi reminder to autoplay third channel at 20:00
   
4. Press stop at 20:02 and attempt to play a fourth channel (server sleeps)
   
5. Wake up the NextPVR server 20:06

One strange observation is that in step 3, the AllowSleep happens after the StartStream for the third channel being streamed. A StayAwake follows 11 seconds later but that's a window of opportunity for an unwanted sleep which I have seen happen a couple times on kodi reminder auto-channel-changes.

On step 4 after pressing stop, NextPVR is allowing sleep within 6 seconds and the server suspends 3 seconds after that. Hardly enough time to consult the guide to choose and play the next channel.

Couldn't NextPVR read the Windows setting "Sleep unattended idle timeout" and wait that amount of time after streaming stops before withdrawing the power request and allowing sleep?
