+//! Output frame reordering.
+//!
+//! NihAV decoders output frames in the same order as they are put in.
+//! In result if you want to have frames in display order you might need some frame reorderer.
+//! This module provides such functionality depending on codec type: audio codecs and video codecs without B-frames do not need any reorderer and can use `NoReorderer` if the common interface is required. Codecs with B-frames should use `IPBReorderer`. For codecs with very complex reordering rules like H.264 or H.256 `PictureIDReorderer` will be added eventually.
+//!
+//! You can find out required reorderer by quering codec properties using `nihav_core::register` module.
