Cannot load M3U8: Technically speaking, a file with the M3U8 file extension is a UTF-8 Encoded Audio Playlist file. What in the world does that mean? Well, simply put it means that they are just ordinary plain text files that can be used by both audio and video players to show where media files are located.
An M3U8 file may give us reference to some Youtube video while another may be created on your system to support your playlist. It refers to a media file or an entire set of media files absolute paths, relative parts or URLs.
Most text editors such as notepad can be used to open and edit these files. However, opening such a file in notepad only let us read the file references. Because text editors are not the same as media players as they cannot play these files.
Programs which can open and use M3U8 files include VLC media players, Windows media players, songbird, Apple’s iTunes and M3U player. On Linux, these files can be opened with XMMS (mainly used for audios but can be used for videos too) while mac users can open it using Coco ModX ( audio player).
HSLPlayer.net can be used to open online M3U8 files (you need to have a URL to the M3U8 file and the files it references are online). With the chrome extension Play HLSM3u8, you can play M3U8 files you find online. This is also useful while fixing video loading errors like Hulu error codes.
