Embodiment Construction

[0058] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0059] as attached figure 1 As shown, a method for recording and live broadcasting of a multi-scene streaming media courseware of the present invention first needs to collect audio and video data, including teacher camera video data, teacher audio data and screen video data, and then encode the collected data respectively, Output multiple real-time streams, namely the teacher's audio stream, teacher's camera video stream and screen video stream. When the recording starts, the screen video key frame supplementary frame algorithm is used to synchronize the recorded teacher's camera video multimedia files and screen video multimedia files; In the process of live broadcasting, the method of synchronous encapsulation and multiplexing of video PES packets and audio PES packets is used to encode real-time video streams and audio streams into TS strea...

Abstract

The invention relates to a multi-scene streaming media courseware recording and direct-broadcasting method, which is characterized in that a recorded teacher camera video multimedia file is synchronized with a screen video multimedia file through a screen video key frame interpolation algorithm in recording; real-time video stream and real-time audio stream are coded to a transport stream (TS) file by synchronously encapsulating and multiplexing a video (PES) photoelectric scanning packet and an audio PES packet to be distributed to a web direct-broadcasting server, the teacher camera video and the screen video are synchronously broadcasted through the multi-video-source synchronous direct-broadcasting control. The method supports the windows / Linux cross-platform run and also supports the multi-source recording and stream direct-broadcasting technology of the teacher camera video, the teacher audio and the screen video, and the media courseware can be directly broadcasted while being recorded.

Description

technical field [0001] The invention belongs to the field of multimedia recording and live broadcasting, relates to the field of audio and video collection, encoding and playing, and in particular relates to a multi-scene streaming media courseware recording and live broadcasting method. Background technique [0002] The development of computer technology, the popularization of Internet and the rapid growth of network bandwidth have brought about the wide application of multimedia technology.
