Embodiment Construction

[0046] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0047] Such as figure 1 As shown, it is a schematic flowchart of an HLS online transcoding method provided in Embodiment 1 of the present invention, wherein,

[0048] Step 11, download the high bit rate HLS audio and video stream according to the pre-configuration and obtain the corresponding M3U8 file.

[0049] In this embodiment, it is first necessary to obtain HLS audio and video streams with a high bit rate. Here, the acquisition of the HLS stream can be performed according to a preset download strategy, or according to an address specified by the user. For example, a download policy may be pre-configured, and after the policy takes effect, specific downloads ...

Abstract

The invention discloses an HLS (HTTP Live Streaming) on-line transcoding method and system. The HLS on-line transcoding method comprises the steps: according to the preset configuration, downloading a high code rate HLS audio and video stream and acquiring a corresponding M3U8 file; according to the M3U8 file, decoding the high code rate HLS audio and video stream to obtain the corresponding TS (Transport Stream) data; re-encapsulating the TS data into low code rate TS data and generating a corresponding low code rate M3U8 file; and according to the user requirement, returning the low code rate M3U8 file and the corresponding low code rate TS data. The scheme of the HLS on-line transcoding method and system can realize conversion of 2.5M high code rate HLS live streaming and output HLS live streaming with 3-channel of low code rates (150kbps, 300kbps and 450kbps), so that the user experience degree is greatly improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an HLS online transcoding method and system. Background technique [0002] HLS (HTTP Live Streaming) is Apple's dynamic bit rate adaptive technology. It is mainly used for audio and video services of PC (personal computer) and Apple terminals. Including an M3U8 index file, TS media segment file and ke encrypted string file. [0003] Commonly used streaming media protocols mainly include HTTP progressive download and RTSP / RTP-based real-time streaming media protocol. These two are basically completely different things. At present, it is more convenient and useful to use HTTP progressive download method. Among them, Apple's HTTP Live Streaming is a representative of this aspect. It was originally a stream developed by Apple for mobile devices such as iPhone, iPod, iTouch and iPad. Now we see that there are many applications on the desktop, and HTML5 directly supports this. ...
