What is m3u8?

M3U8 is a file format used for streaming video content over the internet. It is essentially a text file that contains a list of URLs to media files, along with metadata describing the format and characteristics of each file. M3U8 files are typically used for streaming video on websites, but they can also be used for other types of media, such as audio and images.

M3U8 files use the HTTP Live Streaming (HLS) protocol, which was developed by Apple as part of the QuickTime X and iPhone software. The protocol uses adaptive bitrate streaming to deliver video content to viewers over the internet. This means that the video quality and resolution will adjust automatically based on the viewer's internet connection speed, ensuring a smooth viewing experience regardless of the user's location or device.

One of the key advantages of using M3U8 files for streaming video content is that they are highly compatible with a wide range of devices and operating systems. This is because HLS is an open standard, which means that it can be used by any developer or company to create video streaming applications or services. As a result, M3U8 files can be played on almost any device with an internet connection, including smartphones, tablets, computers, smart TVs, and gaming consoles.

Another advantage of M3U8 files is that they offer a high level of flexibility and customization. Because the files are essentially just text files, they can be easily edited and modified to suit the specific needs of the developer or content provider. For example, content providers can use M3U8 files to create custom playlists of videos or to include metadata such as subtitles, captions, or alternate audio tracks.

To use an M3U8 file to stream video content, a user typically needs a media player that supports the HLS protocol. Many popular media players, such as VLC, Windows Media Player, and QuickTime, support HLS and can play M3U8 files without any additional plugins or software. In addition, many streaming platforms, such as YouTube and Vimeo, use the HLS protocol and M3U8 files to deliver video content to users.

Creating an M3U8 file is relatively simple, although it does require some technical knowledge and experience. Content providers typically use specialized software or tools to create and edit M3U8 files, such as Apple's Media Stream Segmenter or Wowza Streaming Engine. These tools allow users to specify the characteristics of each media file in the playlist, such as the codec, bitrate, resolution, and frame rate.
