I need to play a DRM (ios) video on a webapp page that uses the Ionic framework. This video should be above a ticket screen at the bottom of the page. The video will contain the phrase "valid ticket" and should play for 20 seconds. When a user tries to take a screenshot, the video containing the phrase will turn black as it does in the Netflix app. It is important that this process be completely offline and the video will be embedded directly into the app. This is critical as the operation of the app is completely offline.
