Removal of HAP support for Mobile Support (ie Quest)

[obviousjim]

It'd be great if this repo had an example had a way to be free from HAP support to be driven by Unity Video Player or AVPro.

This would unlock mobile XR device support like Quest, Magic Leap, and various mobile XR platforms.

I only use this project for offline (non-realtime) rendering. I chose HAP just for improving timeline editing UX (frame-accurate editing). So, using it on XR devices is a novel idea to me.

Just a few questions:

• Are you trying to use it with the Universal Render Pipeline? I don't think HDRP with mobile XR is a practical idea.
• Isn't it enough to use the official DepthKit SDK? What is the main reason of using Dkvfx instead of the DepthKit SDK?

Hey @keijiro - understood! We are working on an official Depthkit support for VFX Graph at Scatter, and in the meantime we are grateful that you built this one as lots of folks are using it. We have requests to get this on Quest so I opened it up as an issue.

It would be great to see this using native .mp4 that comes from Depthkit - & the VideoPlayer in Unity, as this allows the video to be downloaded from a URL. I'm playing at doing this at the moment but don't understand how the x,y,z of the depth part of the mp4 works.

Is it possible to use the native Depthkit .mp4 with Dkvfx instead of converting to HAP .mov? I'm using lots of footage in my project, and using the .mp4 files would be great as they are around 10x smaller.

@charliekemp I think you can use the official SDK for that purpose.

@keijiro The old one doesn't work with VFX graph unfortunately.

[keijiro]

@charliekemp Then, you can use the new one, can't you? Sorry but I have never tried it, so I'm just wondering...

@keijiro Their new core expansion package for Unity looks great, but it costs an additional $450 on top of the Depthkit subscription, and your package works great for my needs (except for native mp4 playback!)

@charliekemp Thanks for the information. I didn't know that.

It might disappoint you, but I don't want to have potential interference with their business.

My goal in this project is to provide the functionality of timeline scrubbing with DepthKit + VFX Graph. It's not possible with inter-frame video codecs like H.264 MP4. That's why I wasn't motivated to support .mp4.

@keijiro No worries, I totally understand.
