Emby - Can't play anything: Error starting ffmpeg / Access denied

  • The emby user is a system user and it runs the application and is owner of the working directory. You just need to create a media share that is chmod has at least read for others. The media apps only need to read the files. After you created a media share you decide what user's that you've created have read/write or read privileges. Always try to use privileges and not acl.

    This Native error = access denied thing is odd. It is like something we see when you are using a filesystem that does not work natively with linux. Can you give me a stat command on one of the files you are trying to play.

    stat filename

    Can you tell me how some of the ffmpeg files are chmod 777 ??? Did you mess with their perms??

  • The thing is .. emby sees everything and is even able to write Metadata in the Share after adding to Users group.
    But playing works with no file...

    Maybe its transcoding related? Because aufs? Already thought about getting rid of it and wait for overlayfs...
    But sudo -u emby touch /media/3a55f751-488d-4fb9-8374-33e99b0e8331/emby/transcoding-temp/9bc9f2ba670a4fe0b38c77fdb5f07f61.mp3.test made no error ...

  • cd /media/c1a0b79e-e049-4412-8668-c1963a2b91db/emby

    and give results of:
    ls -la

    I thought this would work but now the error has changed to file not found:

    So I moved it back.

    Output is

    root@nuc:/usr/local/bin# find ffmpeg

    I have no idea what the mkconf thing did, it says emby is running so i stopped the service and it says starting emby...

    Still not working :(

  • @ Malefunk I look at yoru situation later. I'm busy with work.

    Your test with sudo means nothing. You need to enter the shell for the emby user to test which you are not allowed to do because it is system user. We rarely use sudo in Debian.

    The permissions on this file, 01 Da sind wir.mp3, look to be fine.

    Did you install the plex plugin and did it work???

  • On my samba shares, only the files I created/added over samba have the sticky bit. I don't see any commands in omv that would recurse and set the sticky bit on all files. Not sure why samba would either.

    omv 5.6.6 usul | 64 bit | 5.11 proxmox kernel | omvextrasorg 5.6.1

    Please don't PM for support... Too many PMs!

  • Is it maybe because of that? Trying to execute ffmpeg on /media mounted with "noexec" ?


  • ffmpeg needs to be on the system drive. It should not matter that media is on noexec mounted drive. You only need to read it, or write if you adding via a user.

    Give me results of this:

    ls -la /media/3a55f751-488d-4fb9-8374-33e99b0e8331/emby


    stat /usr/local/bin/ffmpeg/20150331/ffmpeg

  • I know. But the log File indicates that the binary on the media share is called.

  • You do not have the symlink to /usr/local/bin/ffmpeg.... In the working directory you have a directory for ffmpeg. It should just be the symlink file that leads to /usr/local/bin/ffmpeg folder. I try to make you some instructions.

  • ok that's what i thought too :)

    I'll try it later, currently i try to get rid of aufs .. it's a very strange system .. after moving and renaming Folders with root,
    i cant access it any more with any other user, although the perms on the pool device are right. The folders on the data
    partition are really messed up and show 4 different versions of the Folder names ...
    How can anyone use that filesystem practically !?

  • Same error with access denied. Is it possible I need to run chown on the media also? I'm worried by doing this that Sabnzbd and Sonarr won't be able to play with the files if I do.
