Explanation:
Detailed explanation-1: -Codecs allow us to tightly compress bulky streams down for delivery and storage. Streaming requires the use of both audio and video codecs. H. 264, also known as AVC (Advanced Video Coding), is the most common video codec; AAC (Advanced Audio Coding) is the most common audio codec.
Detailed explanation-2: -A video codec is software or hardware that compresses and decompresses digital video. In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.
