+ * the chapter list so that even Nero's software accepts it.
+ *
+ * The assumed format is as follows:
+ * - MP4Integer8Property("version")
+ * - MP4Integer24Property("flags")
+ * - MP4BytesProperty("reserved", 1)
+ * - MP4Integer32Property("chaptercount")\n
+ * - MP4TableProperty("chapters", "ref to chaptercount");
+ *     - MP4Integer64Property("starttime")\n
+ *       The start time of the chapter expressed in 100 nanosecond units
+ *     - MP4StringProperty("title", true)\n
+ *       The title of the chapter encoded in UTF-8
+ *
+ * The chapter title only accepts strings of 255 bytes so if a string
+ * only contains simple (two-byte) UTF-8 chars the maximum length is
+ * 127 chars.
