Checking if npvr is recrding or viewing live-tv

[Reddwarf]

I'm trying to use the NScriptHelper with the parameter -inuse to see if npvr is idle or using a tuner, but I can't seem to get this work. How should I use NScriptHelper -inuse in a batch to determine if npvr is recording or showing live-tv?

I'm terrible at batch files, so dont have any example for you. If you run "NScriptHelper.exe -isinuse" (notice the "is"), it'll say "RECORDING" if the system is eiethr recording or watching live tv, otherwise it'll say "NOT RECORDING".

Often I'll keep the NPVR status window open on my client to be aware all the activities that may be going on when all of my tuners are in use.

I bet I'm even worse than you on batch files. I can't figure out how to assign the return value of the call to NScriptHelper to a variable I can compare to "RECORDING". Anyone has a tips?

Here's a quick start

Code:

@echo off
FOR /F "tokens=*" %%i in ('"\Program Files\NPVR\NScriptHelper.exe" -isinuse') do SET ISINUSE=%%i
if "%ISINUSE"=="NOT RECORDING" echo Hi Reddwarf

Thanls! I'd never figured that out myself :o

As it turns out, NScriptHelper is actually returning "RECORDING " and "NOT RECORDING ", including the trailing space.

Not true. But it does write a line to the standard output, so it'll have a carridge return & line feed at the end of the line. This space you're seeing is probably something to do with how the batch file interpretter is handling those characters.

When I test with the script snippet I posted it doesn't return a trailing space.

Well in order to get the compare (==) to kick in I had to add a trailing space to the string, like "RECORDING ". Don't know if it matters but this is on an XP machine.
