Raspberry pi comskip

[DavidD]

Hello, I am interested in getting comskip working with NextPVR. I have done a lot of reading - but still cannot seem to get it reading.

I have compiled and installed comskip. It seems to be working if I execute it on its own.

Created the following comskip.ini in the comskip installation directory /usr/local/bin/comskip:

output_edl=1

live_tv=1

Created the following ParallelProcessing.sh and even tried the same file as PostProcessing.sh
/var/opt/nextpvr/scripts. I made the permissions for executable for other. 

cd /usr/local/bin    > /home/pi/ParallelProcessing.sh

comskip "$1" >>  /home/pi/ParallelProcessing.sh

I misnamed my log file as ParallelProcessing.sh - it should have been ParallelProcessing.log. But still I think it should have worked.
I am getting no log file in any case.

Could you please let me know what I am doing wrong.

You didn't provide your log files. So the only thing we could possible do is speculate.

Did an .edl file get generated?

Also, if you're going to use Kodi as a client, did you also include

Code:

edl_skip_field=3

in your comskip.ini file?

I assume you are running 64bit Raspberry OS with an RPi but we need your zipped logs you get from the main web server page

I have no idea why you are redirecting stdout like this.

cd /usr/local/bin > /home/pi/ParallelProcessing.sh

comskip "$1" >> /home/pi/ParallelProcessing.sh

The edl file did not get generated unfortunately, nor the re-directed logs from comskip .sh file. I have posted the .zip file.

I meant to re-direct the file to a .log file, not a .sh file. It was being re-directed to a different directory - so, it is not overwriting my .sh file. Thanks for the tip about making it work in Kodi - I will try that once I get my .sh files working.

I am running raspbian buster - I do not know how to tell if it is 32 or 64 bit or not. I will try to research how to do that tomorrow and get back to you.

I hope the log helps,
Dave.

You should remove the redirects until you get this working. Comskip will take a lot of resources on a small device which could impact performance

I hope the log helps,

The nrecord.log has this ...

It appears that NextPVR is doing the right thing ... I am not a Linux person so I may be missing the point ... Did you install NextPVR using the deb installer?  Does the NextPVR Server process run under the user "nextpvr"?

[mvallevand]

It appears the @op is trying to create a log file called with a totally odd name /home/pi/ParallelProcessing.sh in a folder that he doesn't have rights for which is way I asked him to remove the redirects. This will also allow us to see in the NextPVR logs how well comskip is performing.

There are other issues with it, it only handles one file and a second recording might block. A second recording at a late date overwrites the file so it defaults the purpose of having a log.

I have attached another log. I might have posted this same log from today multiple time, I don't know. If I did, sorry about that. I am new on this group and I do not know how to delete the multiple copies of the same log that I have posted.
I had recorded two programs. Please look at the recording of Hogans Heroes (the second one) as this is a longer one hour show. The first recording I did was only for 15 minutes - so, I am not sure it would have very many commercials if any.

I made the assumption about 64 bit OS because technically 32 bit linux is not supported, normally users use docker. That being said if it works good news, it will likely not support devices I need to check the deb installer.

sudo service --status-all won't newer service types the documented way is service nextpvr-server status but if you want to see everything it is systemctl --type service

Apparently comskip worked but comskip need to be tweaked for your file type my OTA files in Canada are typically pretty good. I will test something on CHCH test afternoon if you want to compare results.
