3D Full SBS video detection and playback

[stargazer]

I've got loads of 3D films, mostly Full SBS - named something_3D_Full_SBS_LRF - this works with most VR media players such as SkyBoxVR and DeoVR - however jellyfin picks up as HSBS and the video stream describes the aspect ratio as 64:9

I can fix those by editing the metadata - putting 32:9 as the aspect ratio, and setting 3D format to FSBS, however...

Playing in a web browser the video projection by default is 2D and the aspect ratio stays at 64:9 - if I go fullscreen, I can then change the video projection to 3D side-by-side, but the aspect ratio is still wrong.

The only way I can get it to display sensibly is to switch aspect ratio from "Auto" to "Fill" before switching to fullscreen, then setting projection to 3D SBS.

Playback seems to be ignoring the metadata.

Jellyfin has file naming requirements to automatically pick up the kind of 3D it is. Documented here.

As a test I had actually set one with FSBS in the name, and it did set the metadata correctly for the projection - but the playback issues are the same - ignores the metadata.
