从单个视频和循环创建假 hls live stream

Question

I am trying to simulate a live stream from a single video encoded as.ts files. The playlist files looks like, example:

#EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-PLAYLIST-TYPE:EVENT
#EXT-X-VERSION:7
#EXT-X-START:TIME-OFFSET=9.56,PRECISE=YES
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:30.6250,
https://example.com/720p0.ts
#EXT-X-DISCONTINUITY
#EXTINF:29.5000,
https://example.com/720p1.ts
#EXT-X-DISCONTINUITY
#EXTINF:32.8750,
https://example.com/720p2.ts
#EXT-X-DISCONTINUITY
#EXTINF:30.8750,
https://example.com/720p3.ts

The #EXT-X-START:TIME-OFFSET=,PRECISE=YES indicates where the video should be played from which gets updated whenever a new rendition is requested. In safari the stream loops when the #EXT-X-START:TIME-OFFSET value is updated to 0 and so on, but in chrome and firefox, the stream goes into a endless buffering. I am using videojs for my player.

Is there any solution to have the m3u8 manifest loop in firefox and chrome?

Answer 1

The hls spec is confusing at best, it can be pain.

try X9K3

I just added fake live streaming to x9k3 a few weeks ago. x9k3 segments mpegts to hls.

To simulate live playback, x9k3 throttles itself. If a segment is two seconds in duration, x9k3 takes two seconds to create the segment and update the m3u8.

It does not loop a file, however, that would be trivial to add.
