Its because plex in docker, cannot use the codecs to transcode if the execution permission is not applied. That's why I was asking, I had to apply these permissions by hand after running it (New Permissions script), I will keep this in mind for the next time I run it.
Can I change the default permissions in the "new permissions" tool?
I mean these:
For directories: drwxrwxrwx
For read/write files: -rw-rw-rw-
For readonly files: -r--r--r--
I want them to be For read/write files: -rwxrwxrw-
Can it be changed?
