When Media Player example is deployed and run from Qt Creator, it tries to run video from

file:///data/videos/Qt_video_720p.webm

Now that new videos are deployed, media player can't find this video and thus won't start playing when the example has started.

Steps to reproduce:

1. Download and install Boot2Qt 5.11.2 from staging repository.
2. Launch Qt Creator and select Examples -> Qt Embedded (Boot2Qt 5.11.2) -> Media Player
3. Deploy and run the example
4. Example starts, but the video does not start playing
