Problems solved by technology

Although this live broadcast technology pushes the real-time remote audio and video live broadcast technology to a new level, because the flashplayer technology runs on a virtual machine, it has the limitations of remote security sandbox and local security sandbox. Flashplayer cannot perform cross-domain access without configuring a cross-domain security policy. The local security sandbox restricts access to local resources and ports when the flashplayer is running locally, resulting in real-time remote audio and video broadcasting being restricted by application scenarios. Constrained, unable to meet the needs of users
In addition, flashplayer technology also adopts blocking single-thread mode operation, so that flashplayer cannot perform continuous large-scale data calculations, which limits the expansion of real-time remote audio and video live broadcast functions

Abstract

The embodiment of the invention discloses a method for directly broadcasting real-time long-distance audio and video frequency. The method comprises the following steps of: calling an audio and video frequency acquisition procedure through a plug-in unit set up on a browser so as to acquire audio and video frequency data; encoding the audio and video frequency data, and sending the encoded audio and video frequency data to a streaming media server; and obtaining the audio and video frequency data from the streaming media server by using a player for direct broadcasting. The embodiment of the invention also discloses a device for directly broadcasting the real-time long-distance audio and video frequency. The embodiment of the invention can be used for avoiding the safety sandbox problem.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular to a live broadcast method of real-time remote video and audio and its corresponding device. Background technique [0002] With the development of Internet technology and audio and video coding technology, real-time remote audio and video live broadcast has been greatly promoted. Relying on flashplayer technology, Adobe launched its own real-time remote video and audio live broadcast technology: RTMP live broadcast technology. Based on the flashplayer technology supported by Adobe, this live broadcast technology first collects audio and video data through the camera and microphone, then performs H264 encoding and AAC encoding, and then sends the package of video and audio data to the streaming media server through the RTMP protocol for local The player downloads and plays. Although this live broadcast technology pushes the real-time remote audio and vi...
