open Build Phases to add the following libraries This is perfect, and you can easily and happily develop streaming media ........Iv. M3U8 What is M3U8?M3U8 files are M3U files in UTF-8 encoding format. The M3U File records an indexed text file. When it is opened, the playing software does not play it, but finds the network address of the corresponding audio/vide

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 m3u
has a corresponding solution. HLS protocol Detailed As you can see, HLS has a total of three parts: Serve, CDN, Client. The main content of the HLS protocol is about m3u8, which is very simple to generate and parse, with examples such as: Simple Media Playlist Master Playlist with multiple bit rates HLS Optimization Technology Because the client each requ
, you can simply think of m3u8 as a playlist with multiple TS files. Players are played in order, all finished and then request the m3u8 file, to get the playlist containing the latest TS files to continue to broadcast, cycle by. The entire live process relies on a constantly updated
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

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
advertised in the main playlist.) I spent the next few days trying my best to getffmpeg to cooperate, but to no avail... On a 150 kbit/s stream, it produced 220Kbit/s... On a 800 kbit/s stream, it produced a 250 kbit/s stream. on top of this, if I told FFMPEG to use AAC, the audio sounded horrible (MP3 was much better at the same bitrate !) After days of experimentation, I finally got the results I wanted from free tools for creating HTTP streams for

There are a number of tools to help the server provide support for "start= ..." such as parameters, but there are many limitations and problems in their use. A more efficient way is to cut the long video into fragments (usually 5-10 minutes), strung together by a playlist. When the player drags the playback, it downlo

. HTTP Live Streaming HTTP Live streaming is an HTTP-based streaming media transport protocol proposed by Apple.

Why to use HTTP Live streamingRefer to WikipediaHTTP Live Streaming (abbreviated as HLS) is an HTTP-based streaming network Transfer protocol proposed by Apple. is part of Apple's QuickTime X and iphone software system. It works by dividing the entire stream into small HTTP-based files to download, one at a time. When media streaming is playing, clients can choose to download the same resources at different rates from many different alternative sources, allowing streaming media sessions to ac
