I seem to have succeeded, but 50% of the time it loads without showing the video controls. All the user sees is a blank, black area. They are still able to click where the play button is and view the video, but they would have to already know it is there.
The other half of the time the controls are displayed.
What would cause such an inconsistency?
Is there another option of displaying an image until the user plays the video, wherein I could direct them to push the button?
Could be that the version of iPad you are testing it on doesn't like the codec of your video. My iPad played the video consistently every time I refreshed the page.
