Troubleshooting

Nothing happens when i insert a disc

For me personally i had to add the --privileged flag to my container for it to fully work, However i'm very new to docker there may be a better work around to get it to work. But this is how i got it working.

You can check if your udev rules are working on the host machine via linux logs

tail -f /var/log/syslog | grep ARM

This should show when you insert a disc

xxx ARM: container 'arm-rippers' status: "Up 24 seconds"
xxx ARM: Starting rip

If it doesnt you udev isnt setup on the host machine.

MakeMKV cant find drives

MakeMKV requires both drive identifiers to be passed into the container for example if lsscsi -g outputs

cd/dvd TEAC DVD-ROM DV28SV R.0C /dev/sr0 /dev/sg5

You will need to add

--device /dev/sr0
--device /dev/sg5

to the docker run command

Failing to do so may mean that the rest of ARM can find the drive but MakeMKV fails as it uses SCSI commands to interact with the drive

Docker is adding jobs but no files are created

Check the docker to make sure both the UID and GID match to a user outside the container, and the user has write permissions to the media directory. You may need to chmod your media/music directories outside the container.

Changing where the docker puts files

DO NOT try to change these paths in the arm.yaml

Instead change the containers volume paths. These can be changed to suit your needs

    -v "/my-music-path:/home/arm/Music" \
    -v "/my-config-path:/home/arm/config" \
    -v "/my-logs-path:/home/arm/logs" \
    -v "/my-media-path:/home/arm/media" \

My volume paths point to a CIFS mount - but now the database is locked

This is caused by a byte-range lock on the mount by default. To fix this, the CIFS mount of your host needs the nobrl flag.

NVENC doesn't work

Be sure that both variables for NVIDIA_DRIVER_CAPABILITIES=all and --gpus all are set as NVENC won't work without them
