OMV - Can't play anything: Error starting FFMPEG, access denied

Hello,

I have recently installed the Emby plugin on Open Media Vault however I'm not able to play a show I wish to watch. This is the error I can locate on the logs when I try:

It repeats this same error multiple times for some reason.

I have had no problems using Plex Media Server to play media files, so I went to the /etc/init.d/emby.conf file and replaced the user and usergroup fields with plex so it would run under the same user. I still have the same issue.

Does anyone have any suggestions?

I think @@tekkb will know. It sounds like it can't execute due to permissions.

Tekkb is on this forum also? He's been helping me over on the OMV forums

 

He's offered a suggestion I'll give a go when I get home. I will post the solution when I find it for historic reasons in case others come across this error.
