Abstract

The invention relates to the field of video compression, and particularly relates to a video compression method of multiple video streams. The invention provides the video compression method of multiple video streams, and the method comprises the following steps: acquiring video streams of multiple paths of input sources and inputting the acquired video streams in the same processing device, then performing video stitching to synthesize multiple paths of video streams into one path, if on-site external audio recording exits, compressing the synthesized video stream and the on-site acquired audio stream together, and then performing transmission; otherwise, randomly selecting one audio input as audio to be compressed together with the synthesized video stream, and then performing transmission. The video compression method of multiple video streams provided by the invention not only can improve compression efficiency in a transmission process, but also can recover a real scene and save uploading bandwidth.

Description

technical field [0001] The invention relates to the field of video compression, in particular to a video compression method for multiple video streams. Background technique [0002] In the live broadcast process, in order to ensure the shooting quality, most of the shooting devices are used to shoot the same scene, and then the videos shot by the multiple devices are compressed and transmitted. Moreover, during the live broadcast, the amount of uploaded data and the speed of transmission are particularly important. In the same scene, the pictures captured by different shooting devices will have the same part. If these videos containing the same picture are compressed and transmitted separately, it may affect the compression efficiency, increase the amount of uploaded data and cause the speed of transmission reduce. Furthermore, there are many external audios in the live broadcast. For how to transmit video streams and external audio obtained from multiple shooting devices...
