Post-Processing with FFMPEG [Ubuntu shell script]

[mahjohn]

SAB on Ubuntu 64.

I have a script that I use to change the container from MKV to MP4, remove subs, and convert audio to AC3. It does this using AVCONV (ffmpeg), and when finished deposits the new mp4 in a different directory. All of this works fine. However, when I call the script in SAB post-processing, it errors out. So what's going on? It looks like it is looking for a specific file called "*.mkv" instead of using "*" as a wildcard.

I chown/chmod as plex and sab and couchpotato use the same account...and want to ensure no permissions issues. Is there a better way, probably but I'm pushing the extent of my Linux abilities with this script as is... running manually this works well

Code: Select all

#!/bin/sh
#Change .MKV container to .MP4 and convert audio to AC3
for f in /videos/movies/_pending/*.mkv; do avconv -i "$f" -format mp4 -vcodec copy -acodec ac3 -strict -2 -sn -threads 3 -movflags +faststart "${f%.*}.mp4";$.mp4"; done
mv /videos/movies/_pending/*.mp4 /videos/movies/incoming
mv /videos/movies/_pending/*.mkv /videos/movies/completed
chown -R plex:media /videos/movies/incoming
chmod -R 777 /videos/movies/incoming
exit

calling from SAB post-processing..it errors out.

Thanks!!!

I would put this before and after "for f ..." line:

Code: Select all

ls -al /videos/movies/_pending/
ls -al /videos/movies/_pending/*.mkv

... and then check in the output what you get.

That worked much better...failed on the permissions mod though. In the /etc/init.d/sabnzbdplus file I have USER=plex, which is correct, as I keep Plex, SAB, Couch Potato, and Sonarr with the same user account. However, when the script runs it errors on the chown/chmod and i see

Code: Select all

sabnzbd media

For the movie submitted from sab and being processed. "media" is the group. I don't want to disable the sabnzbd user on the server, as it looks like sab is using it...

1. Where is the sab user coming from if the etc/init.d/sabnzbdplus specifies USER=plex?
2. Is it possible to call the script as the plex user from within sab or inside the script? (i have no idea on this one).

thanks for the help, i'm getting closer.
