The information popup displays a text message with all information about a file gathered by the model. The function below generates the message.

Another feature of the sample application is file's information displaying. Multimedia files provide information about their content which can be accessed using the Player API. The data include:

+
    +
  • album name,
    • +
  • artist name,
    • +
  • author name,
    • +
  • genre,
    • +
  • title,
    • +
  • year,
    • +
  • audio codec name,
    • +
  • video codec name,
    • +
  • audio sample rate,
    • +
  • audio channel,
    • +
  • audio bit rate,
    • +
  • video frames per second,
    • +
  • video bit rate,
    • +
  • video size.
    • +
+

The functions below are used to get the file's information.

Note that not every file provides all the mentioned data.
