Abstract

The embodiment of the invention discloses a video coding parameter configuration method, device, equipment and storage medium. The method includes: determining the code rate and quantization parameters of the video to be broadcast according to parameter configuration rules and video quality parameters; encoding and streaming the video to be broadcast according to the code rate and the quantization parameters. The embodiment of the present invention introduces the index of video quality parameters to coordinate and quantify the playback quality of live video. When configuring the encoding parameters, only the video quality parameters need to be set in advance to set the video playback quality, and then according to the parameter encoding rules, as The video quality parameter is based on determining the bit rate and quantization parameters of the video to be live broadcasted, so that the live video is encoded and streamed according to the determined bit rate and quantization parameters. The embodiment of the present invention simplifies the configuration process of encoding parameters through the introduction and setting of video quality parameters, and improves the generality of encoding parameter configuration and the efficiency and accuracy of encoding parameter configuration.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of streaming media, and in particular to a method, device, device and storage medium for configuring video encoding parameters. Background technique [0002] With the rapid development of Internet technology, applications based on streaming media technology such as network video, remote monitoring and Internet telephony have been widely promoted in people's lives. Video usually needs to be compressed and encoded before it can be used for live streaming. Correspondingly, how to configure video encoding parameters is particularly important. [0003] In the existing technology, the operation and maintenance personnel of the live broadcast software need to rely on the previous experience in configuring encoding parameters, and before the live broadcast, weigh the live content of the specific live video, the quality of the live video, and the encoding parameters. The relative relations...
