Does an audiobook player plugin exist? Requirements are read .mp3, .m4a and .m4b. Buttons for short and long jump forward and backwards. Ideally treat all sequenced numbered files as one audiobook.
There's a nice driod example called Smart AudioBook.
There are many audiobook players. I've never paid attention to how many format are covered as I use mp3 almost exclusively.
Into what do you want to plug one?
