Audio mixing and transcoding method based on OTT box

Abstract

The invention relates to an audio mixing and transcoding method based on an OTT box. The method comprises the following steps: reading original audio data to a first buffer area; reading the original audio data from the first buffer area, and adding the original audio data to a second buffer area; judging whether the original audio data in a second buffer area reaches a preset frame number; if the original audio data in the second buffer area reaches the preset frame number, taking the original audio data out of the second buffer area for transcoding to obtain preset-format audio data; and writing the preset-format audio data into a preset-format file, wherein the size of the first buffer area and the second buffer area is integral multiple of the preset frame number. According to the audio mixing and transcoding method based on the OTT box, transcoding work is informed through the audio data; and a coding thread does not need to circulate constantly to check whether there is data to be processed, so that system power consumption can be reduced greatly.

Description

[0001] This application cites the priority of the earlier application number CN201510957848.8. Technical field [0002] The present invention relates to the technical field of audio processing, in particular to an OTT box-based audio mixing transcoding method and device. Background technique [0003] When users perform voice services through OTT (Over The Top, providing various application services to users through the Internet) box, most of the output is PCM (Pulse Code Modulation) voice data. If you save it directly as an audio file, it is impossible To be played by the player, data encoding and compression must be implemented first, and then converted into other formats. When performing format conversion, the traditional method is to establish an encoding thread for data encoding. When there is data in the encoding thread, the processing starts. The encoding thread needs to continuously loop to check whether there is data to be processed, which causes a lot of system consumptio...
