send/receive encoding and decoding API overview	The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/ avcodec_receive_packet() functions provide an encode/decode API, which decouples input and output

▼libavfilter	Graph-based frame editing library
▼Buffer sink API
Buffer sink accessors	Get the properties of the stream
Buffer source API
▼libavformat	I/O and Muxing/Demuxing Library
Demuxing	Demuxers read a media file and split it into chunks of data (packets). A packet contains one or more encoded frames which belongs to a single elementary stream. In the lavf API this process is represented by the avformat_open_input() function for opening a file, av_read_frame() for reading a single packet and finally avformat_close_input(), which does the cleanup
Muxing	Muxers take encoded data in the form of AVPackets and write it into files or other output bytestreams in the specified container format

►AVOptions
Evaluating option strings	This group of functions can be used to evaluate option strings and get numbers out of them. They do the same thing as av_opt_set(), except the result is written into the caller-supplied pointer
Option setting functions	Those functions set the field of obj with the given name to value
Option getting functions	Those functions get a value of the option with the given name from an object
AVDictionary	Simple key:value store

Audio FIFO Buffer
Audio channel masks	A channel layout is a 64-bits integer with a bit set for every channel. The number of bits set must be equal to the number of channels. The value 0 means that the channel layout is not known
