FreeNAS Corral and Plex not Playing videos solution
Plex does not playing back videos with either the AC3, EAC3 or TrueHD when the network share of /trancode is located on a network share.
If the /transcode is located on the host For example /mnt/tank/media to /transcode
The easy solution is to select the entry and hit delete at the top right (red trash icon).
Save the container
After this you will see the /transcode mount existing but it will be in the VM instead
You will now need to correct the permissions of the new /transcode directory.
Click on the Docker Console button for your container and in the new browser window type
chown -R plex:plex /transcode
