Simple Player

The Simple Player application demonstrates the range of audio and video capabilities of the emulator. It includes sample files in a variety of formats and can play files from the emulator's persistent storage or from HTTP URLs.

The player portion uses a generic javax.microedition.media.Player interface. The player displays duration, media time, and controls for running the media file. If metadata is available in a file, the player enables you to view the information, such as author and title. In the case of MIDI files, if karaoke text is present in the file, it displays on the screen during play. Graphical user interface controls can be viewed on the display screen if applicable. You can access these controls by selecting one of the media samples in Simple Player, then pressing the Menu button to view and select the desired command.

Select Simple Player then click Launch. The demo includes the following media samples:

In addition, Simple Player parses ring tones in Ringing Tones text transfer language (RTTTL). See http://www.convertyourtone.com/rtttl.html for information on RTTTL.

The Simple Player includes a common set of commands that control media playback. The commands are available from the Simple Player menu, and some have associated keypad buttons. Table 1 describes these commands.

The commands may or may not be available depending on the media type that Simple Player is playing. In addition, some commands can be invoked using the keypad buttons. The following table describes the availability of commands and their keypad equivalents.

Note that a short list of commands and the corresponding keypad buttons is available in the Simple Player application itself. Just choose the Quick Help command from the menu.
