Http-live-streaming Protocol Analysis:Unrestricted transmission of multimedia data streams. The protocol supports media data encryption and stream switching (for example, different bitrate).Media data is transferred immediately after creation, playing near real-time. Media data is typically transmitted using HTTP.Playlists consist of an ordered list of media URIs and information labels, each of which points to a media file, which is a fragment on a single contiguous stream of media.In order to p

Examples are as follows:For more information on m3u8, please refer to the website:http://blog.csdn.net/test_1207/article/details/8160863m3u8 the meaning of the other fields:

1. Improved the file tag read/write algorithm, supported id3v2.4, and better supported Chinese tags
2. Supports batch modification of file tags;
3. Enhance the playback
Step 1: add the Player Code (do not use other JavaScript players). I only need the simplest one. In fact, to simplify the code for playing background music, the following code is the simplest.
Loop = "-1" indicates infinite loop playback. You can set the number of playback times and use a specific number instead. For example, if you want it to play twice, loop = "2"
Controls = "controlpanel" can be omitted
Width = "0" Height = "0" indicates hidden playback. To set the player size, set the value,
is updated whenever a new media file is completed by the staging device. The index file is used to confirm the availability and location of the media file. The segmented device can also encrypt each media segment and create a key file.
Media fragmentation is saved as a. ts file (MPEG-2 Media Stream), and the index file is saved as a. m3u8 file, which is an extension of the. m3u format that holds the MP3 playlist

The playlist is *. m3u text. You can use NotePad to open the mp3 absolute path.
Paste the Code directly and write it in a short time. You can refer to it as follows:

segment may not rely on the preceding segment to decode and play independently. To do this, the TS file must contain only one MPEG-2 program, at the beginning of each file should contain a program associated table (PAT) and a Program mapping table (PMT), and a file containing video must also contain at least one keyframe and other sufficient information (such as a sequence header) to complete the initialization of the decoder. The index file takes an extended

What are the advantages of m3u8?
After searching online, there are different opinions. My personal understanding is that it can adapt to multiple bit rates. Based on network bandwidth, the client selects a file suitable for its own bit rate for playing, ensuring the smoothness of the video stream.
In iOS device and Mac, HTTP can be used for distribution. Among them, playlist is a m3u8 file extended by M3U
