Video Not compatible is Accelerate framework

[mortocks]

Both GVRSDK and CardboardSDK (not sure which one to use) seem incompatible with projects that include apples Accelerate.framework.

To replicate add the framework to the video examples. Projects build fine but throws EXC_BAD_ACCESS when first frame of video attempt to render.

Actually it looks like it's not the Accelerate framework that's the problem but a conflict with the Wikitude AR library.

[sorenbryder]

I am having the exact same problem with Wikitude and GVRSDK. Did you manage to find a solution?

[mortocks]

In speaking to the Wikitude support staff - apparently they override some core libraries that GoogleVR uses. They're looking at a re-write but don't hold your breath. Unfortunately my only choice was to write my own GoogleVR Clone using SceneKit.

Thanks for your answer. It is really too bad Wikitude is doing that kind of stuff. Especially since they charge quite a bit of money for their library.

Is it possible to take a look at your clone? I am willing to cover some of your expenses if I can use it as a working replacement in my project.

[mortocks]

Unfortunately it was for a client project so I can't share it - but it was heavily inspired by the work of this repo

https://github.com/Aralekk/simple360player_iOS

Should give you pretty much everything you need to roll your own 360 video player
