Yep, @Plex this request hasn’t gone away, nor have the demands of your Plex Pass paying customers and, it would seem, nor has your arrogance in continuing to ignore your fee-paying customers.
As with identifying Dolby Vision, this must be one of the easiest things that you could implement so why do you continue to be so belligerent?
Just a quick side note (not advertising): PM4K does (all of?) that.
This isn’t an easy issue to solve, but it’s possible.
I’ve got open-source JavaScript you can use that works with MediaInfo.
Plex’s “Media Info”
Plex has its own way of getting information outta the file that looks like this:
MediaInfo
That same movie looks like this in MediaInfo:
Using metadata like the format name: “Dolby TrueHD with Dolby Atmos” or even the format itself “MLP FBA 16-ch”, you can reliably figure out if a file is Atmos-encoded.
DTS:X is more tricky, but the XLL means DTS-HD MA. XLL X means DTS:X. I have one demo file lacking the X that my AVR decodes as DTS:X. I attribute that to either a MediaInfo bug or something wonky in that file’s audio track.
The only one that’s tricky is IMAX Enhanced as MediaInfo is wrong about it in 2 of my DTS:X demo files, but it’s right for the other 4 files. Even if you don’t put IMAX Enhanced, it’s essentially DTS:X with the center height and “voice of god” rather than the middle tops. Not gonna break the bank to get that wrong. Better than the inaccurate “DTS-HD MA 7.1” base track.
Audio-encoded formats
Audio-encoded formats like Dolby Stereo and Auro-3D are very difficult to pick out; in fact, it’s impossible to ever know for sure unless the audio track is marked a certain way. Either way, I found that if the channel count is 4 and the channel layout is “L R”, that was a good indicator of Dolby Stereo (or similar knockoff version) encoding.
In those cases, it’d also be helpful if Plex gave some hints because you never really know if you need to enable Dolby Surround or Auro-3D unless it’s part of the {edition-Auro-3D} name.
This would help troubleshoot or validate where issues lie.
Another request that is still wanted.
This seems like it should be a no-brainer. Display it, please!
Voted !!
I’m not quite seeing the point of labelling the audio tracks properly when the vast majority of Plex clients can’t play the lossless codecs anyway. Still. It’s just rubbing salt in the wound.
Just because some clients can’t play the lossless codecs is no reason to dumb down the ability of clients that can.
This is easily added since my Ugoos AM6B+ running CoreELEC and PM4K shows the full details of the audio and video specs of a given MKV. If Kodi can do it, so can Plex. They just can’t be ars3d doing it and are once again showing the finger to their Plex Pass (Lifetime in my case) customers whose primary reason for signing up is playback of local media, not streaming of D-grade cr4p that no other platform wants.
Maybe with the advertised new Plex dashboard / server control coming, we can edit (overwrite) the codec information… Yeah, that’s some work to do, but then we could get proper codec display. Again, Plex is probably not allowed to identify Dolby stuff, etc, as they are bound to licensing…
I don’t understand why you can’t just add “3D” to the end of the name. DTS-HD 7.1 3D or TrueHD 7.1 3D and so on.
But what do I know… Plex doesn’t even properly recognize Dolby Digital 7.1 and displays 5.1.
