# FFmpeg
2+
3+
<https://en.wikipedia.org/wiki/FFmpeg>
4+
5+
Offers a high level API to abstract multiple codecs.
6+
7+
Codecs are algorithms that compress audio and video.
8+
9+
You want to compress them to:
10+
11+
- save disk space, e.g. when you save a film to disk. The container (e.g. OGG), contains a coded video file.
12+
13+
- save bandwidth when it is limited. E.g. networks, USB cables (there are professional cameras that encode video to send higher quality over the cable)
14+
15+
FFmpeg also takes care of breaking up the decoding into packages and sending / receiving it.
16+
17+
Video / audio compression is different form that of images since multiple images can be compressed together as they differ very little between them.

## libav
20+
21+
Fork because of war. Still highly compatible.
22+
23+
History of the fork: https://en.wikipedia.org/wiki/Libav#History
24+
25+
libav is going to die now that Debian switched back to FFmpeg.

Write C/C++ with some extra magic annotations, and generate bindings for several languages, including Python and Java.
8+
9+
Awesome because it can parse your **existing** headers and generate bindings to a ton of languages. Almost no need to touch your C / C++ code.
