Problems solved by technology

[0004] 1. When the video image is synthesized, the CPU resource overhead is high, which will cause the CPU utilization rate of the recording server to be too large, but the CPU resource used for audio mixing is not much, so that the generated audio and video files may have audio and video content. synchronization problem
[0005] 2. When merging images, the images of both parties need to be compressed, which will lead to a decrease in the quality of the combined image
[0006] It can be seen that, adopting the above-mentioned storage method of video call data, there will be problems of image quality degradation and out-of-sync audio and video content.

Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The core idea of ​​the present invention is: the video data of both sides of the video call is synthesized with the video call mixing audio data respectively to obtain two video files, like this, for the both sides of the video call respectively generate respective video files and save, can avoid Audio and video content generated by image synthesis on video data may be out of sync and image quality may be degraded.

[0039] figure 1 It is a schematic flow diagram of the method of the embodiment of the present invention, such as figure 1 As shown, the method for saving video point-to-call video realized in this embodiment mainly includes:

[0040] Step 101 , during the video call, the two terminals conducting the conversation resp...

Abstract

The invention discloses a method and a system for storing video pickup video, wherein, the method comprises the following steps: two terminals carrying out a conversation send video data and audio data generated by each terminal to a video server respectively during a video conversation; after the video call process is finished, the video server performs audio mixing processing on all audio data generated in the video call process, synthesizes the obtained audio mixed with the video data generated in the video call process by each of the terminals, and saves the synthesized two video files. Byadopting the invention, the saved audio and video contents can be synchronized and the image quality can be improved.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and system for storing video point-to-call videos. Background technique [0002] During the terminal video call, in order to preserve some evidence, it is necessary to save the voice and video data of the call between the two parties in the recording server. At present, for the preservation of video call data, the usual method is: combine the video data of the real-time call between the two parties into a video image, and mix the audio data of both parties, and then synthesize the synthesized video file and the mixed audio into an MP4 file Save it. [0003] There are the following problems in the method for saving the above-mentioned video call data: [0004] 1. When the video image is synthesized, the CPU resource overhead is high, which will cause the CPU utilization rate of the recording server to be too large, but the CPU resource used for audio mixing is not much...
