     * Currently supported format is SubRip. Note that a single external timed text source may
     * contain multiple tracks in it. One can find the total number of available tracks
     * using {@link #getTrackInfo()} to see what additional tracks become available
     * after this method call.
     *
     * @param fd the FileDescriptor for the file you want to play
     * @param offset the offset into the file where the data to be played starts, in bytes
     * @param length the length in bytes of the data to be played
     * @param mime The mime type of the file. Must be one of the mime types listed above.
     * @throws IllegalArgumentException if the mimeType is not supported.
     * @throws IllegalStateException if called in an invalid state.
