Run custom .bat file at start and end of recording

[bm_00]

I am looking to run a custom .bat file when next pvr begins recording and when it ends recording. I stumbled upon the ability to add .bat files to the scripts folder under the data folder. I saw that the PararellProcessing.bat and PoatProcessing.bat scripts are run at both the beginning and end of recording. I simply copined and renamed my custom .bat files to the folder under the correct names but they do not run when recording begins. Is there something I am missing? Do the .bat files need a special layout? The ones I am trying to run are scripts to turn on and off an led via a program. The .bats work when perfectly when run on their own.

ParallelProcessing.bat is run at the start of a recording. Postprocessing.bat is run at the end of a recording.

These processes are run by the Recording Service, which is running as the 'localsystem' account which sometimes trips people up when they're trying to do custom. For example, if your LED control utility uses WM_COPYDATA (aka the clipboard) to send messages to some server process, those messages wont make it there, because the two processes will be running in a different desktop session.

I believe that a couple of other things the often trip up people is not explicitly setting the default directory (i.e. a "CD" command in the batch file) and not providing the full path to any things that might be called in the batch file.

Yes, that's true - incorrect assumptions about the default directory often lead to things not being found etc too.

That makes some sense. After a little more research I discovered that whatever command I add to the batch file does appear to run as it appears task manager (cmd for the led and I tried just notepad for testing which must be due to the different desktop user sessions. I know the Recording Service runs as the system account but is there anyway to somehow run the .bat as a different user? Thanks

No, but you could try changing the account the recording service runs as.

No, but you could try changing the account the recording service runs as.

Would this be achieved by going to services--> NPVR Recording Service--> Properties--> Log on than enter my username and password?

[sub]

yep, that's the one.

Alternatively, for a test, you can stop the service, and just run "nrecord.exe RUN" from the command line, and see if it then works.

[bm_00]

yep, that's the one.

I have tried modifying the service but when I both type in and search for the correct username and enter the correct password and try to restart the service it throws an error of 1069 login failure. Research shows that usually means an incorrect password but it is the right one as its the same I use to login
