Embodiment Construction

[0016] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the embodiments described here are only used to illustrate the present invention, not to limit the present invention.

[0017] See attached figure 1 , which shows the system structure and method flow of the low-latency streaming HLS (ie, HLS+) of the embodiment of the present invention. The low-latency streaming HLS technology of the present invention is exactly the same as that of the RTMP stream when the stream is returned to the source, and there is no need to build an additional HLS slice system, which simplifies the process of returning to the source.

[0018] The workflow of the described low-latency streaming HLS (ie HLS+) is as follows, including the following steps:

[0019] Step 1. The playback user makes a playback request to the edge server;

[0020] Step 2. The edge server receives the request, and automatical...

Abstract

The present invention provides a low-latency streaming HLS implementation method, the method includes: dynamically generating an independent m3u8 list for each playback request, dynamically and quickly generating a small slice only for this playback request from the media data cached on the server File, in this way the traditional HLS stream processing method. When the user makes a playback request to the edge server, a UUID is automatically assigned to the user as an identification. The edge server starts RTMP back-to-source streaming, quickly starts slicing the RTMP stream data to be played, and generates an independent m3u8 list. The player gets The list and the first 3 slices are ready to play. The present invention is exactly the same as the RTMP stream when the stream is returned to the source, and there is no need to build an HLS slicing system. The stream media and RTMP use the same cluster, which can save a set of equipment groups, N computer rooms and equipment. This method is simple for customers to configure, easy to use, fast to go online, simple domain name CNAME, and can reduce latency. Compared with the 40s latency of traditional HLS, HLS+ can be at the same level as RTMP.

Description

technical field [0001] The present invention relates to the field of streaming media system design, in particular to a low-latency streaming HLS implementation method. Background technique [0002] In recent years, with the multi-dimensional overall improvement of online video technology, interactive live broadcast modes such as "show field" and "game live broadcast" have brought a new experience of real-time viewing and in-depth interaction to the majority of netizens, allowing the interactive live broadcast mode to rise rapidly, and It has gradually become the Internet social portal in the new era. The online video technology supporting interactive live broadcasting is a relatively complex and professional field, involving the application of multidisciplinary technologies such as audio and video codec, image optimization processing, streaming media transmission and distribution, and multi-terminal playback. The attraction of interactive live broadcasting is that the end u...
