Script Files

[vintdiesel]

For V4, I have a Postprocessing.bat file for compressing recordings to .mp4's using ffmpeg. By tweaking the settings, I have been able to store and archive shows to a 1/3 of the storage space without sacrificing noticeable quality.

With V5 under a Linux environment, I am guessing I will have to translate the .bat files to Bash script?

It'll look for a .NPVR-data/scripts/PostProcessing.sh file on Linux. You can add similar login in there.

Thanks for the reply sub,

Is ffmpeg part of the NextPVR docker container installation, or will I have to install ffmpeg separately?

Yes, ffmpeg is included in the docker container.

[vintdiesel]

Cheers sub, I shall try writing a script then.

OK I tried writing some simple echo statement to write to a processing.log file but I can't seem to get it invoked when a recording finishes.
I cannot find the path on my system as stated above.

If I open a console as root, PostProcessing.sh is located in mnt/appdata/NextPVR/Config/scripts

If I open a console from the docker, the location to the same file is /config/scripts/, noting that config is in all lowercase to above.

Maybe I haven't got to grips with Linux and docker containers yet, the learning curve is steep for me at the moment.

Is that path right? Is npvr.db3 in /mnt/appdata/NextPVR/Config/?

I am a bit confused with @vintdiesel's post because I am not sure if he is talking about a docker or linux install but I tried in linux
based on the thread topic and the instructions seem to work but I don't know if the logic works

Code:

running the command from the command line works

Yeah I was too. I'm pretty sure he's using docker, so post should really have been in the docker forum.

Argh. I see what I need to change. Thanks.

[vintdiesel]

Thanks Guys,

Apologies for the confusion, yes I am running this in docker on a NAS box. Originally the post was about scripting and how to go about writing them, so I though the question could be best posted in the Linux forum for the best audience coverage.

Now I am covering pathing in the docker environment, so it may be best for me to create a new post and continue correspondence in that forum.
