So which lines in the scripts is it that you have modified/added?

Will it also make the app play more videos? I got the same problem with the app refusing to show videos after a certain number.

Im trying to use the device database

It seems that my fix was deleted... The general idea is under this post.

Finally, for be available to playback videos of a lot of trackers is necessary to make some modifications to VideoPlaybackBehaviour.cs and TrackableEventHandler.cs of the video playback sample. The modifications are in regions called MOD.

The files are attached.

I dont know if it would be better to only load and unload the videos instead of initialize and desinitialize them. And in ActivateAutoPlay maybe it would be better if the yield is shorter... I didn´t try.

This issue is related to this one.

To support 30 videos, you'll need to load and unload them programmatically at runtime using the VideoPlayerHelper API, which is accessed using the VideoPlayer property of the video player instance. You also may need to store the videos remotely and stream them to your app via HTTP - if so, load them using their URL.

Take a look at the VideoPlayback sample's Trackable Event Handler script to see how the VideoPlayerHelper API is employed.

The video playback sample initializes and loads all videos when the scene starts; but for several trackers with video playback the videos have to be initialized or loaded when their trackers is found.

I will try to fix this and post it over here.

In Xcode I get the log for this four missing videos like this:
