Understanding HLS and M3U8 Recordsdata
Let’s delve into the intricacies of HLS and M3U8 recordsdata.
What’s HLS?
HLS is an adaptive bitrate streaming protocol developed by Apple. It really works by breaking down video content material into small, manageable chunks, usually just a few seconds in size. These chunks are encoded at totally different high quality ranges, or bitrates. The HLS participant dynamically switches between these bitrates primarily based on the viewer’s community situations.

segment2.ts
#EXTINF:10.0,
segment3.ts
#EXT-X-ENDLIST
On this instance, `#EXTM3U` signifies the file is an M3U8 playlist. `#EXT-X-VERSION` specifies the HLS model. `#EXT-X-MEDIA-SEQUENCE` defines the beginning sequence quantity. `#EXT-X-TARGETDURATION` units the utmost length of every phase. `#EXTINF` gives the length of every phase, and the next line comprises the URL (on this case, a relative path) to the video phase.
