Calling mp3_play_data API plugin to play mp3 file.

(1/1)

I would like to call mp3_play_data to play a mp3 file for a plugin I am hacking/writing but cannot workout if the first argument needs to be a pointer to a buffer containing  mp3 or sound data loaded with other plugin functions or can it just be string representing the directory/filename of a mp3 file
ie mp3_play_data("./rockbox/test.mp3",100,,)

I have searched the source code and cannot find other plugins that are calling mp3_play_data. A previous thread mentioned looking at test_codec (sic codec_test) but this has not clarified it for me.

Would anybody have some sample code which uses mp3_play_data?
