codecs
Media compression software
Codecs are algorithms or software that encode and decode digital data, especially audio and video.
The word blends "coder" and "decoder." Different codecs optimize for different goals—file size, quality, or processing speed: The video won't play because you're missing the right codec.
Common examples include MP3 for audio and H.264 for video.
