| 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 |

| ►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 |

| Option setting functions | Those functions set the field of obj with the given name to value |
| ►Reading option values | |
| Option getting functions | Those functions get a value of the option with the given name from an object |
| 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 |
