Compatibility with 4.19.2

[alexandreMarie]

I everyone,

I'm currently building an app which will use both ARCore and Vuforia (the user will have the choice to use either ARCore or Vuforia) and I'm using Unreal 4.19.2 AND Vuforia 7.1-34 (now that 6.2.10 Android is no longer available).

First, the project compile and can be deployed on an Android device. The problem is I have a black screen even if everything is set up (License Key, new Vuforia Actor with auto possess set to player0 etc...) It really could save me a HUGE amount of time and furthermore, we could considerably increase the community around that project.

So if anyone has some knowledge about it or is currently working with that version...

Best regards

Alexandre

So, my mistake for the black screen, I've forgotten to configure for Android Platform.

But,

Now it looks like the video stream is an average of the color or just the first pixel but who is taking all the screen.

Anyway the screen is blinking many colors if you want a representation of it. We understand there is a video stream.

So maybe it's a setting problem ?

Best regards,

Alexandre

@alexandreMarie did you solve the problem?

[alexandreMarie]

Nope :(
I've finally moved for ARCore. They have implemented Image Recognition for the 1.2 release.

@alexandreMarie But arcore does not supported at so huge list of devices as vuforia. Also I can't compile this plugin for 4.20, do you know something about it?

[alexandreMarie]

Yeah I know :/ I will try to move it for 4.20 later I think

[heberuriegas]

@kosedmos what kind of problems you have with compilation for 4.20?

[kosedmos]

@woohoou Thank you for your interest!
I use Win 10 64-bit and vuforia SDK 7.2.23, so when I enable this plugin and press compile I receive next into the logs:

And all closed after it. I'm not so good in C++, but it's really important for me to make this module able to work.

Thank you!

Hey, looking into this as I discovered that ARcore image tracking is rubbish in comparison.

I've never compiled plugins before - can someone help me with compiling this for the latest version of UE4? (4.21.2 as of writing.)

-Update

Followed a tutorial on recompiling plugins however I get this error when running "RunUAT.bat"

Can someone help me out with this?
