The document discusses codecs and how they are necessary for playing compressed video files on computers. Codecs are programs that decompress compressed video and audio files so they can be played. Most computers do not come with all necessary codecs pre-installed, so codecs need to be downloaded and installed separately in order to play different types of compressed video file formats. The document recommends using codec packs, which bundle many common codecs together for easy installation on a computer.

player Player when you play video files, you're playing will be the player, strictly speaking, only Player is not playing. We have been playing using "another program, such as" key called "codec" Player is. It is to play "unzip" the compressed video. We open with key not only Player, software video playback will not be able to play video files by itself, always corresponding to the door of each box there is a door of two video data and audio data It may be easy to understand the term.
Codec part1 To play on a PC video data that has been compressed by the compression format that A (A door), you will need to extract the A (Play) for "(codec A) key," for example. In order to play the audio data compression format that B (B door) have been taken, you will need to extract the B (Play) for "(codec B)" key.

Must be installed on each computer to obtain compression formats are supported by a certain number, a certain number of codecs. In this state there is no codec I would not be able to play video files on most personal computers.
