Using Serial Commands To Create Playlists
Create playlists “on the fly” with the mpgLoadDef and
mpgLoadNextDef commands. Use these two commands to define a
default (i.e. looping) playlist of MPEG files on any given channel.
To make a playlist on a single channel:
1. call mpgClearDef to clear the old default playlist.
2. call mpgLoadDef to specify the first file in the list.
3. call mpgLoadNextDef once for each additional file, the order
they should play.
4. wait a few seconds for the files to load.
5. call
mpgPlay to start playback.
If you want to create a playlist that only plays once, use the
mpgLoad and mpgLoadNext commands as follows:
1. call mpgClearDef to clear the old default playlist.
2. call mpgLoad to specify the first file in the list.
3. call mpgLoadNext once for each additional file, the order they
should play.
4. wait a few seconds for the files to load.
5. call
mpgPlay to start playback.
Filename Conventions
The Mantis provides three interfaces, that allow the creation
and naming, or transferring of files: front panel controls,
WebView, and External Control Commands. To insure
compatability between them, filenames must conform to the
following conventions:
- up to 214 alphanumeric characters (capitals and
lowercase) in length
- can include spaces, dashes, and underscores
- can begin with either alpha or numerical character
