Problems solved by technology

There is also a solution for recording in cloud conferences, which skips screen mixing and directly encodes screenshots of the moderator’s display interface, which increases the upstream bandwidth of the client and the performance and energy consumption of the client.
[0005] The existing conference video multi-screen solution cannot record conference elements such as graphics and pictures according to user operations
In the combined screen recording, it does not solve the problem of multiple input sources. When the frame rate is different, the combined screen of the video will produce some split screen fast playback, and some split screens will not be smooth.

Embodiment 1

[0040] Such as Figure 1-Figure 4 As shown in the present invention, the processing method for recording video combined screens in cloud conferences specifically includes the following steps:

[0041] S1: Analyze the recording file, analyze the control protocol, obtain the layout information of the combined screen and the width and height of the split screen, and at the same time, analyze the operation of the control protocol;

[0042] S2: Input the non-video conference elements into the graphics and picture conversion module for unified processing. The modules input to the graphics and picture conversion module are point coordinate data and JPEG data / files and BMP data / files and PNG data / files and GIF data / The file, after conversion, is output into the YUV data format supported by the composite screen module;

[0043] S3: Send the YUV data and H264 video ES data processed by the non-video conference elements to the combined screen module for combined screen processing, and ...

Embodiment 2

[0066] The present invention is a processing method for recording video combined screens in a cloud conference. The main processing and implementation steps are as follows:

[0067] First, it is necessary to analyze the recording file, analyze the control protocol, and obtain the layout information of the combined screen and the width and height of the split screen. At the same time, it is also necessary to analyze the operations of the control protocol, such as inserting meeting elements, enabling / closing annotation operations, and switching combined screens Layout and other operational information.

[0068] Secondly, the non-video conference elements are input to the graphics and picture conversion module for unified processing. The input to the graphics and picture conversion module is point coordinate data, JPEG data / file, BMP data / file, PNG data / file and GIF data / file ,Such as figure 1 As shown, after the conversion process, it is output into the unified and correspondin...

Abstract

The invention relates to a processing method and device for screen combination of recorded videos in a cloud conference, and the method comprises the following steps: S1, analyzing a recorded file, analyzing a control protocol, and obtaining the layout information of screen combination and the width and height of split screens; S2, inputting non-video conference elements into a graphic picture conversion module for unified processing, and outputting the non-video conference elements into a YUV data format supported by a screen combination module after conversion; S3, sending the processed YUV data of the non-video conference elements to a screen closing module for screen closing processing; and S4, performing H264 coding on the data after screen combination processing according to set screen combination coding parameters, and sending the coded H264 video ES data to an upper-layer service for container packaging processing. For the device provided by the invention, the method is executed. According to the invention, rapid and stable video synthesis of various conference elements for improving the conference effect in the conference can be ensured.

Description

technical field [0001] The invention relates to a processing method for combining screens of recorded videos in a cloud conference. [0002] The present invention also relates to a processing device for recording and combining screens in a cloud conference. Background technique [0003] With the rapid development of video cloud conferencing and the diversification of video conferencing media, time domain and geographical restrictions have been broken, and video conferencing can be quickly conducted anytime, anywhere. Customers have higher and higher requirements for meeting recording, not only need to record and store the video and audio data of all participants in the meeting, but also need to record some auxiliary data intact according to the operations in the meeting. These auxiliary data include point graphics, JPEG / BMP pictures, GIF animations, and video and audio shared by users in the meeting. The auxiliary data can be used to improve the meeting effect and the user'...
