Nscripthelper

[jcjefferies]

I wrote the batch file below many years ago to go in the postUpdateEPG.bat to reboot the server when it is not recording. It does not work in V5 so assumed it was just a case of changing the file location in the "set" statement but nscripthelper is now a dll file and it fails with Unhandled Exception. Is it possible to get this script working under V5?

REM Reboot if not recording
set NSHelper=c:\"program files (x86)"\npvr\nscripthelper.exe

:check
FOR /F "tokens=*" %%i in ('%NSHelper% -isinuse') do SET condition=%%i
echo %condition%
IF %condition% =="NOT RECORDING" goto reboot

:delay
sleep 60
goto check

:reboot

echo "About to reboot"
shutdown /r

... nscripthelper is now a dll file ...

The usage is now ... dotnet nscripthelper.dll -option ...

You will need the Net Core runtime ... https://dotnet.microsoft.com/download
.

You need to to install the netcore 3.1 runtime and run

dotnet NScripthelper.dll

Note: JavaWiz seems to have indicated that your old script may not have been very useful hopefully his comment is no longer true

Thanks both for the help. I have seen mention of dotnet previously and did wonder if it was something like that.
I have not looked at it for years and it has certainly being rebooting the server as occasional late night failed recordings have not carried over to the next day but will check if it has been waiting before rebooting!. Martin I will check out the link you mentioned later .

Thanks again

I installed .NET Core Runtime 3.13 is that the correct software?
When I run:-
dotnet "C:\Program Files\NextPVR\nscripthelper.dll" -isinuse

I get error saying it cannot find any .NET Core SDKs.
dotnet --info says I have no SDKs installed!

Returning to this problem the earlier “SDK” error message disappeared after I installed the x64 version of Dotnet! The commands below gave output of “Recording” or “Not Recording”!

cd C:"\Program Files\NextPVR"
dotnet NScriptHelper.dll -isinuse

Below is the modified PostUpdateEPG.bat file for V5 which reboots the server after an EPG update if the server is not recording. The earlier version dated back to Vista where I found it reduced the number of occasional "Failed" recordings especially annoying if you have not used NextPVR for a day or two then you could find a string of failures! :-

echo off
REM Reboot if not recording
cd C:"\Program Files\NextPVR"
set NSHelper=dotnet NScriptHelper.dll -isinuse
:check
FOR /F "tokens=*" %%i in ('%NSHelper% -isinuse') do SET condition=%%i
echo %condition%
IF %condition% =="NOT RECORDING" goto reboot
:delay
timeout 60
goto check
:reboot
echo "About to reboot"
shutdown /r

I'm trying to use the PostUpdateEPG batch file from post #6, but it exits with "Login failed". What step is trying to login to something?

echo off
REM Reboot if not recording
cd C:"\Program Files\NextPVR"
set NSHelper=dotnet NScriptHelper.dll -isinuse
:check
FOR /F "tokens=*" %%i in ('%NSHelper% -isinuse') do SET condition=%%i
echo %condition%
IF %condition% =="NOT RECORDING" goto reboot
:delay
timeout 60
goto check
:reboot
echo "About to reboot"
shutdown /r

Are you using the default 0000 pin, if not "-pin:1234"

Are you using the default 0000 pin, if not "-pin:1234"

Thanks sub, I didn't even know that was required.  My old script just worked in V4, but that was using the .exe version of NScriptHelper. 

I modified this line to pass the pin:

set NSHelper=dotnet NScriptHelper.dll -isinuse -:pin:xxxx

Now it works as I expected.

If you are interested, I've written a helper utility that makes interacting with NScriptHelper easier from cmd or shell scripts.  It can be found on this thread.  You'll still have to fix the pin issue however.

Your code for detecting a recording in-progress would be something like this:

Code:

:Check
  python3 NPvrHelper.py --isrecording
  if %ERRORLEVEL%==0 GoTo :Reboot
  ... delay ...
  GoTo :Check

:Reboot
