The “poster” is the image file that is displayed when the video is unavailable. The source type is the mime type of the video. The “src” attribute specifies the location on the file.

The track kind is the type of timed text such as the captions. The label is the title of the text track. The “srclang” is the track language. A preferred track can be chosen as the default text track.

How to Use:

Wait for video to load.
Click the play button.
