Video-recording generation method based on audio-video stream-splitting storage

Abstract

The invention discloses a video-recording generation method based on audio-video splitting storage. The method comprises the following steps: step one, performing caching processing when receiving anaudio stream A and a video stream A and the audio stream B and the video stream B; step two, selecting the time needing the synthesis to synthesize the video; step three, selecting the audio stream Aas the audio-video synthesis reference basis, and the audio stream A and the audio stream B as the audio mixing, and extracting the resolution of the video stream A to scale the video stream B into the parameters of the video stream A; when the audio stream A is in the sound state, using the video A picture, and when the audio stream B is in the sound state, using the video B picture; and using the reference basis video A picture when detecting the silence or that the audio stream A and the audio stream B are all in the sound state, and then performing synchronization processing, computing andadjusting the timestamp, guaranteeing the audio-video synchronization, and finally integrating into the video-recording file. The video-recording presentation effect of the technical scheme is relatively novel, the picture with the sound can be displayed, and the effect is similar to voice following.

Description

technical field [0001] The present invention relates to the technical field of computer information data processing, in particular to a video generation method based on audio and video split storage. Background technique [0002] The existing two-party call video generation method: such as figure 1 As shown, two video files are generated, the sound is mixed, and the video is not mixed, that is, a single-screen video file with audio mixing is generated. Therefore, the current recording effect is that the voices of both sides can be heard, and only the image on one side can be seen (the image and sound on this side are synchronized), and there will be one sound without corresponding video picture. In order to solve this problem, it is necessary to upgrade the solution to support the mixing of video images to achieve the best video experience effect, that is, all sounds and images can be matched synchronously. Contents of the invention [0003] The purpose of the present in...

Therefore, the current video recording effect is that you can hear the voices of both sides, but only see the image on one side (the image and sound on this side are synchronized), and there will be one sound without corresponding to the video screen.
