I am not able to play that video either. The problem is identical with either source video:

1) I aim at my target and the play button appears as expected

2) I tap the play button and the screen goes black

3) playback controls appear in the upper left corner of the screen

4) playback begins, but only the sound, there is no video

5) none of the controls actually do anything

Note that on-texture playback works fine. This has something to do with the full-screen player, and appears to have something to do with the screen layout of the player components. It seems they were positioned using pre-iOS6 layout systems, and these no longer work on modern builds. That may be a red herring though, that's nothing more than my gut feeling.

Are you working with the native iOS VideoPlayback sample app or the Unity one? Could you post a screenshot of the controls appearing in the upper left corner?

I am using the native iOS sample app. Screen snap attached.

In VideoPlayerHelper.mm I have tried...
