M3U playlists can be used to play media stored on your computer or stream media over the Internet. Playlists used to play local files include file paths that point to those files. Playlists used to stream media include URLs that point to that media.
The M3U format was originally designed to describe audio playlists, comprised of .MP3, .WAV, and other audio files. However, the format is now commonly used to save video playlists, comprised of .MP4, .TS, and .WEBM files. Note that M3U files do not contain the media itself. Instead, they contain information used to open and play media files.
注: M3U is short for MP3 URL, which is itself short for Moving Picture Experts Group Audio Layer 3 Uniform Resource Locator.
