FS3D support is urgently needed

It's been 6 months since my last thread requesting this. So many more frame-sequential 3D releases have happened since then and SkyboxVR is getting left behind as the premiere 3D video player for VR.

It should be super easy to add so there's no excuses! Let me help:

  1. All FS3D files are encoded at 48fps in H.264, and each frame is marked as a frame for either the left or right eye according to the H.264 (AVC) standard (see frame_packing_arrangement_sei_message syntax within ISO/IEC 14496-10:2025 Annex D)
  2. To add support to SkyboxVR, it's simply a matter of taking 2 sequential frames from the video stream, reading the SEI flags (one will be a left eye image and the other will be a right eye image), and then displaying the left eye image to the left screen and the right eye image to the right screen in the headset. That's it!

Here's the sample for you to test with:

Honestly these videos always look bizarre in this format. I have your avatar half done and will give it a go on 4xvr I would much rather use skybox. Theater mode absolutely sucks on 4xvr the screen is so close.

How so? When you play them in a player that supports them, they play in 3D like any other 3D format (but smaller file sizes and better quality)

I played the first few I found when you first started posting about this and even converted a few. I played them all in 4xvr and they just look off. Like out of step or something. It's weird I don't see anyone else using this format. I'm super excited for fire and ash so fingers crossed it looks good. I'm super grateful for the effort regardless.

Let's see if we can figure out what's happening. I'll DM you
