Black camera video with Vuforia 4 on Unity 4.6.5 built as iOS project

[gary9716]

Hi, I have encountered a problem that my iOS app built from unity project which camera video was totally black on screen and the camera video source is from the ARCamera Prefab provided by Vuforia with version 4.2.3. and the unity project only contains the following libraries : Vuforia and OpenCVForUnity. I have tested the iOS App with only Vuforia library and it can normally obtain the camera video but if I add OpenCVForUnity library into the project then the iOS app running on iPhone or iPad would become the situation mentioned above. Because I saw there is a example that combine Vuforia and OpenCVForUnity on Unity 5, have you tested these setting on Unity 4.6 and it work normally as the same as Unity 5. If you have done this before, please tell me the build setting in XCode

In Unity 4.6, It seems the black screen problem occurs while using the combination of Vuforia and OpenCVForUnity. I am investigating the cause.Unfortunately, please use the Unity5 at the moment.

OK, Thanks for replying. It's workable on Android in Unity4, and there is another issue about using development mode in Android platform of Unity5. I found that If I used development mode in Android platform of Unity5 to build with these two libraries, it would also cause the black screen problem. But if without using development mode, everything would work normally as the same as in Unity Editor. Please also check this issue. Thx a lot

I have an issue, this begin when I updated the SDK to Vuforia 4, this occurs when I try to draw over "ARCAMERA" from vuforia 4, (an image recognition component in the cloud), doing use the method "ONGUI", this not renderized in Android. This mean when I try to open the scene using the "ARCAMERA", only display what renders in the fullscreen camera and not displayed the texture over this, like say in the code. This It does not occurred previously update the SDK. The strange, when I press Play over the project in UNITY this can display the texture in the scene but don't render the webcam in the Notebook. This means in the Notebook DISPLAY the the texture but NOT render the camera and to pass the project to Android this NOT render the texture but YES render the camera.

So, I need to know what form I can generate texture and/or image over the render of ARCAMERA, this is for detect the input from user over this texture the application.

Thanks in advance.
