Which is probably fine for your users. In every browser it plays video and has basic controls like a start/pause button, a timeline and a volume control. While the video is playing they even look identical: it's the video, playing; with controls only visible on hover.
The differences aren't an issue for the actual user, they are an issue for the designer that tries to have the website look and feel the same everywhere. Preferably look the same as it does on their MacBook.
