Which Tuner is being used?

[herringj]

Is there a way to know which of the 3 tuners NPVR is using at a given time, recording, etc?

You should be able to see which tuners are in use with the Device Status window.
If you wanna know what was recorded on which device in the last few days, go to the log folders and look at ndigitalhost-**.log* files.

I also use compskip that logs all recordings in this format in ParallelProcessing.log

Code:

2016-02-20,18:01:03,55 - CTV News Montreal_20160220_18001900 (382698) recording from channel 12 on tuner 20

This line in ParallelProcessing.bat does the logging.

Code:

echo %date%,%time% - %~n1 (%3) recording from channel %2 on tuner %4 >> C:\Users\Public\NPVR\Comskip\ParallelProcessing.log

Thanks. when does ParallelProcesing.bat get invoked? when the recording service is first started, when the recording of a show is initiated? do other processes beyond recording also use ParallelProcessing.bat?

thanks for the quick reply and insights.

The System plugin can show this info too.

You can also right click on the N tray icon and then click on Show Status.

rgr on show status.
the real goal is to know if the live tv is on tuner 1, and all background recording is on tuner 2 & 3.
the idea being that if I have bad signal on 2 & 3 on a recording, I can check the antenna feeding those tuners.
that kind of thing. all tuners are good but was curious on a way to find out.

alternate thought is how do I know which tuner is being used at any given moment for the live tv stream. is it always tuner 1?

ParallelProcessing.bat gets invoked just after each recording gets started and is passed various parameters such as the channel, tuner ID, file name, etc. I've never heard of anything else using ParallelProcessing.bat besides the Recording Service when it begins each recording.

There is a very complicated algorithm that is used to determine which tuner gets selected for any given recording. Presuming that all channels are available on all tuners, a live tv stream could be coming from any of the tuners. NextPVR will generally try to optimize the tuner usage (i.e. use the same tuner for multiple recordings or a recording & live tv, etc.) when possible.

Using the ParallelProcessing.bat to generate a log file which lists all of the recordings and which tuner was used for each can be extremely helpful when troubleshooting quality issues since you typically don't know that there is a quality issue until later when you watch a recording (and often then the regular logs which show the same information have rolled over and been deleted).

thanks. all good info.

You may also want to try nscripthelper with the -now parameter

For example, on my machine it returns:

Code:

c:\Program Files\NPVR>NScriptHelper.exe -now
DCR-2650 / HDHR Prime 1318E35A-0 - Recording E:\PVR\Recordings\TVShows\Odd Squad\Odd.Squad.S01E04.Blob.on.the.Job;.Party.of.5,4,3,2,1.ts
DCR-2650 / HDHR Prime 1318E35A-1 - LIVETV

Which says I am recording on my 1st tuner, and watching live TV on my 2nd tuner (3rd tuner is doing nothing).
