You set your own I/O through a AVIOContext, which you set in AVFormatContext->pb. mplayer, gstreamer and others use this to provide custom I/O into libavformat. In this class, though avio_alloc_context(), you set function pointers to read/write/etc. from your customs tream, plus some private data (e.g. pointer to your class).
