Bash Question

Handbrake-CLI on Synology NAS

I installed Docker on my Synology NAS (DS415+) and tried to run the handbrake-cli (via this package) over ssh.
However, something seems to be broken. I get the following error message after a simple

sudo docker run -d supercoder/docker-handbrake-cli -i ~/_inProgress/input/movie.mkv -o ~/_inProgress/output/test.mp4
(I shortened the error message for readability):

- hb_init: starting libhb thread

I followed this blog post originally and got the same message there.

Executing the same thing on my desktop works without any problems.
Anyone got an idea?

Answer Source

When running the docker instance, your input and output file do not exist in the container. You need first to mount the input and output directories of you file system as volumes (as shown in the blog post you shared)

-v ~/_inProgress/output/:/outout:rw
-v ~/_inProgress/input/:/input:ro

And then you use those paths in the options:

-i /input/<file>
-o /output/<file>

Good luck!
