Thanks for the update.

Glad you were able to get this working :)

I have multiple videos that I wanted to show on the same image in the same place, I ended up putting them all in there and then setting them to inactive and activating them when I needed them to show up and that worked.

The other image does not have anything attached to it but when it is scanned by AR camera on my android a GUI button shows up which lets my instantiate the video prefab

I do not understand why you are trying to instantiate a video prefab at run-time?  Have you checked and compared it against the one at design time?

m_autoplay stays true but the new video does not seem to be responding to it normally

What did you learn by stepping through it with the debugger?

I am familiar with recreating the scene and have done that a few times already. Here is what is happening I have two images in my scene one with prefab video on it already wich works exactly as it is supposed to. The other image does not have anything attached to it but when it is scanned by AR camera on my android a GUI button shows up which lets my instantiate the video prefab. The prefab shows up and will start playing if I click on it but it will not autoplay. I have tried setting the m_autoplay bool to always be true in the script but that did not help.

This exercise may help you.

The objective here is to show how to replicate the essence of the Vuforia-VideoPlayback sample scene using the Vuforia prefabs and the drag and drop approach of Unity

·      Create a new Unity project

·      Import the Vuforia video playback unity package

·      Create a new scene

·      Drag the ARCamera prefab into the Unity scene

o   Under the DataSetLoadBehaviour in the Inspector tick “Load Data Set StonesAndChips”, and the Activate checkbox below this

·      From Qualcomm AugmentedReality/Prefabs drag the ImageTarget prefab into the scene

o   For the Image Target select “StonesAndChips” as the dataset and the Image Target should change to the Stones texture

·      From Vuforia Video Playback/Prefabs drag the Video prefab to be the child of the Image Target

o   In the Inspector under “Video Playback Behaviour (Script)” set the path to VuforiaSizzleReel_1.m4v

·      Drag the TrackableEventHandler from Scripts to the Image Target (this plays the video)

·      Remove the DefaultTrackableEventHandler script from the Image Target as it is not needed.

·      Autoplay works already, however tapping the video does not yet work  In order to fix this simply create a VideoPlaybackController script, and fill with the code below), and then attach this to the ARCamera.

I tried creating a new project and only loading one of the videos that come in the videoplayback sample as a prefab and that still did not work. Do you know if creating as a prefab is changing a setting somewhere?

I suggest opening up a second instance of Unity and trying to identify what the difference is with your scene/project.

This might explain the different behaviour.
