Correct misunderstanding of video encoding and decoding

Video encoder, encoder, is the tool that puts "master" into a certain encoding; video decoder, decoder, restores some encoding to color. People often confuse the two, in order to facilitate understanding and memory, we can remember the encoder into the in code der, that is, the device to put the code into; decoder, predecessor "de-" is the meaning of decomposition, that is The code is decomposed into a video stream and an audio stream. We often see what the video player option has. "Separator", the separator is used to separate the video stream and the audio stream of the video file for supply to the corresponding video decoder. And audio decoder parsing. This memory is not easy to confuse.

The general operating system comes with some commonly used multimedia decoders. For example, windows media player (WMP) comes with wma and wmv format decoding and encoder. Users can listen to wma songs and CD- Audio is converted to songs in wma format. In general, decoders are commonly used, and encoders are not commonly used. Because WMP comes with a small number of decoders, users often complain that it can't play all-round. The users who pay attention to it know that WMP can become a versatile player by installing the Windows Media codecs package, while most users choose third-party playback. Devices, such as KMplayer, Thunder Player … … these players will bring their own decoders, and some even bring the encoder, the strange thing is that these players' decoders are not provided to WMP calls, the reason is to guess Let's go.
