Folder location PostProcessing.sh with LibreElec

[retrofan]

Hi,

I would like to do some tests with PostProcessing.sh and ParallelProcessing.sh with LibreElec.

What exact location do I have to put those files?
I already gave them all the permissions (777) but the files aren't executed after recording.
The commands are correct as I tested it with SSH.

The script file must contain a last line with 'exit 0' as well?

It will be /storage/.kodi/userdata/addon_data/service.nextpvr/config/scripts/

I will update the wiki with these there have been a couple of recent posts on the LE file location.

Thanks! I will try again.

However, there's a placeholder.txt in /storage/.kodi/addons/service.nextpvr/nextpvr-bin/data/scripts/
which states:

Batch files can be created in this directory.

PostProcessing.bat
PostCancel.bat
ParallelProcessing.bat
UpdateEPG.bat

For LibreElec this is different as it uses .sh scripts instead of batchfiles .bat

Yes that is confusing it probably shouldn't be in the program directory, but not sure if NextPVR uses both. For sure the scripts folder works but sub would need to comment.

I'm sorry, but no matter what I try, the PostProcessing.sh script isn't executed even though I used chmod +x / 777.

This is what I tried, just a test:

#!/bin/bash
./storage/.kodi/addons/tools.ffmpeg-tools/bin/ffmpeg -y -i "$1" -c copy -f mpegts "$newfile"
exit 0

Why isn't the script executed?

First upload your zipped logs from the first settings page and we can confirm it is running.

Here you go.

You probably aren't letting your test recordings finish

2024-08-13 16:21:19.367 [DEBUG][13] No /storage/.kodi/userdata/addon_data/service.nextpvr/config/scripts/PostCancel.sh

create a PostCancel.sh script from your PostProcessing.sh

I am surprised that your script runs from ssh with the leading . and the output filename not set.

Okay, now in the end I understand.

1. You have to write a script from scratch in the nano text editor directly in LibreElec with SSH

or

2. You have to remove the DOS line endings created by a Windows text editor (which is copied to LibreElec) in SSH with:
dos2unix /storage/.kodi/userdata/addon_data/service.nextpvr/config/scripts/PostProcessing.sh (or other script)

Watch the filename: it must be PostProcessing.sh (Postprocessing.sh or postprocessing.sh isn't the same in Linux).

And it has to be executeable, done with chmod +x PostProcessing.sh

Now it finally works, thanks!

The script is sh and not bash in LibreElec and exit 0 is advised. Included paths for ffpmeg aren't needed.

And never forget to create both PostProcessing.sh and PostCancel.sh in case the scheduled recording is cancelled earlier by the user.

Maybe helpful for the wiki?

The different scripts are already documented, but I don't think the NextPVR wiki is the best place to instruct Linux users on how to write batch files or Windows users to write shell scripts, and also why I don't support scripts or ffmpeg in general. Definitely best to test for yourself though

That being said some things to consider in your script, the stdout from scripts are written to the log to help debugging but once that is done you should try and avoid spamming the logs. In this case use -v panic as an input option. For ffmpeg in scripts (especially Windows, but LE does have optional versions of ffmpeg too) you might not want the system default.
