I added a new section to my Plex library with some iPad compatible M4V files. These are already tagged and Plex does read the included meta data (Local Media Assets as 1st agent).
But I noticed that some data fields are ignored. Are they not supported yet?
Maybe the M4V agent cannot write the Sort Title fields at all. I can remember Sander1 telling me this is done by the scanner.
I hope there is a way to read the Sort Title field from the video file. I don’t want to set it twice. For english titled movies this is almost no work but foreign language movies have to be done all manually. See this forum topic on this issue.
It’s quite possible that the local media agent needs to be extended to support some of these fields, we’ll look into it. “Sort title” should be able to be written by the agent, it’s just that PMS doesn’t read that in yet.
Can you provide a sample (tiny) M4V with these fields set?
Gentle bump…
Based on the local media agent, I’ve tried to write my own agent to get more atom data out of my M4Vs.

Nice MTI, thanks!
This part looks odd to me:
<br />
Log("Rating: " + rating)<br />
#if len(copyright) > 0:<br />
Atom "----" [iTunEXTC] contains: mpaa|R|400|
atom, specifically the “R” (and not “Explicit Content”, which is what the rating atom contains). That, the “R” is what is displayed in iTunes and what should go in under “Content Rating” in Plex.
The copyright atom is not being read, since nothing is logged.
If you feel like it, you can uncomment this
#Log(data_atom.attrs)
in the find_data function to see which atoms are being read.
Now, I’m a total amateur in this regard, so maybe more atoms are in fact being read. This is suggested by the fact that ‘data_atom.attrs’ doesn’t contain any info about the cover art embedded. But the embedded poster is still picked up.
Here’s the mp4trackdump, which shows all the atoms contained in the file
I’ve updated the above code a bit. 
I noticed that the local media.bundle has the mutagen pythons included. A little trial and error, and this is now how my agent looks, using mutagen.mp4 instead of mp4file:

OK, so I solved the issues myself. Here is some code that will read most meta data from mp4 video files (tagged with Subler/iTunes or the like). You may want to edit the split() parts, since the code below is tailored to split according to the non-standard way that I tag my files.
Maybe someone will find this useful

Thanks, we’ll get this mainlined
Was this ever added in? I’m having a helluva time getting it to recognize my data. I tag everything so I don’t have to depend on outside (and sometimes incorrect) meta data. I’m just not sure if something is broken or this hasn’t made it in yet.
Thanks!
Frank
IIRC, a good chunk of it was. If you’re missing specific data and can provide a sample file, we’d be happy to have a look!
