Abstract

The invention discloses a start-stop audio fault tolerance method and system in RTMP audio and video stream pushing under an Android platform, and relates to the technical field of mobile application development and streaming media. The method comprises the steps: setting a private static member variable and a public member method during recording, and in the case of audio pause during pushing, through the static member variable, indicating and changing the state; calling the pre-recorded silent audio frame through the member method to seamlessly join the audio stream for pushing, thereby solving the problems that the playing picture is stuck and the playing fails due to the fact that the recording end starts and stops the audio in the RTMP audio and video stream pushing process.

Description

technical field [0001] The invention relates to the technical fields of mobile application development and streaming media, and relates to a fault-tolerant method and system for starting and stopping audio in RTMP audio and video push streaming on an Android platform. Background technique [0002] With the rapid development of mobile Internet technology, the comprehensive popularization of 4G networks and the rapid deployment of 5G networks, many emerging industries have been born, among which the most popular are streaming media industries such as live broadcasting and surveillance. The process of live video broadcasting can be roughly divided into six steps: acquisition, processing, encoding and encapsulation, streaming to the server, server streaming distribution, and player streaming playback. [0003] Acquisition is the first link in the entire video streaming process. It obtains the original video data from the system's acquisition device and outputs it to the next lin...
