Abstract:To tackle the problem that the existing video on demand (VOD) technology cannot be directly used in the intelligent mine management and control platform, this paper designs a VOD technology based on the adaptive bitrate streaming media transport protocol of HTTP and FFmpeg open-source library. The technology includes client module, web request processing module and multimedia processing module. In this technology, the client module sends the video request to the web request processing module through the set video source information. The web request processing module uses the video source information in the request to call the multimedia processing module to obtain the multimedia streaming file and returns the request address of the streaming file to the client. After receiving the streaming media address, the client requests and plays the video file according to the streaming media address. By introducing hls.js open-source library, the technology can achieve VOD in any client using HTML5 technology, realize the embedded video information of cross-terminal browser, multi-business module and plug-in removal of the intelligent mine management and control platform, and meet the needs of fusion display and collaborative analysis of video information and various business information of coal mine safety production.
