Already tried that, lots of times, plus it creates new ones wrong as well, which is how I found the problem

and what probably caused the old ones to be reset incorrectly.

Are all the 3D movies that have aspect ratio issues full-SBS or are some of the half-SBS?

Could you please show me the output like this for a file with the flag set, and also the same file with the 3D flag cleared.  I believe the server is taking the aspect ratio directly from the file

Hi,

No problem, here's the same movie with the flag cleared:

Is the 3D flag set when you receive the files, or are you adding this flag?

 

None of my 3D files have this flag, and when it's set ffprobe is reporting the aspect ratio incorrectly.

 

If you remove this flag does the file still work correctly in 3D?  I'm not convinced the flag should be set.

Yes it is, I have not added the flag manually, as I say some of my older 3D that worked when I first watched them, stopped working when I tested them whilst looking into this, so I assumed something changed recently-ish?

 

Yes they do as I said before, if I remove the flag then emby shows the aspect ratio correctly and it plays as expected.
 

 

I still don't understand why Plex works with them all correctly with or without the flag and auto switches into the correct 3D mode.

It's possible that Plex is calculating the aspect ratio instead of using the ratio reported by ffprobe as Emby does.

 

Tonight I'll add some sample output and get Luke to review it for options

@@Luke, when the Stereo 3D flag is set in the mkv video stream header, the display_aspect_ratio gets bumped from 16:9 to 32:9, but the sample_aspect_ratio also goes from 1:1 to 2:1.  When the server determines the aspect ratio it's only looking at display_aspect_ratio and results in images being stretched.  To be honest, I'm not certain that the file is correct as none of my 3D movies have the Stereo 3D flag set, but that doesn't mean this is incorrect.  Should the server (or client) be trying to handle this?

Hi,

Have you been able to fix this?

 

I am finding that nearly all my older 3D movies (which I have watched in the past on Emby with no problem) are in the same situation.

 

Also, I notice that there is a 1.0.70 and 71 tizen talked about but Samsung still shows the .69 version.

Not yet.
