Embodiment Construction
[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0029] Before introducing the video stream processing method provided by the embodiment of this application, some concepts involved in the embodiment of this application are first introduced:
[0030] The Real-Time Messaging Protocol (RTMP), also known as the Real-Time Messaging Protocol, is a proprietary protocol originally developed by Macromedia for transmitting streaming audio, video, and data between a Flash player and a server over the Internet. There is an agreement.
[0031] System call (system call), refers to the program running in the user space of the operating system to request the operating system kernel to run with higher privileges; the system call provides the interface between the user program and the operating system; most of the system interactive operati...

The invention provides a video stream processing method and device, electronic equipment and a storage medium, and the method comprises the steps: receiving stream data of video collection equipment through a virtual camera, and obtaining video stream data; storing the video stream data into a kernel space of the electronic equipment; copying the video stream data in the kernel space into a user space of the electronic equipment; and displaying the video stream data in the user space on a browser of the electronic equipment. In the implementation process, stream data of video acquisition equipment is received by calling a driving program of virtual camera equipment to serve as video stream data to be stored in a kernel space; and then the obtained video stream data is directly copied to the user space from the stored kernel space, so that the browser can access and display the video stream data in the user space, and the time delay of playing the video stream by the browser is effectively reduced.
Description
technical field [0001] The present application relates to the technical fields of image processing and video processing, and in particular, to a video stream processing method, device, electronic equipment, and storage medium. Background technique [0002] Streaming Media (Streaming Media) refers to a technology that compresses the media data in the media file, sends the data through the network segment, and transmits the media data on the network in real time so that the media data can be used in time. The streaming media technology makes the media data The data packets can be sent like water; if you do not use streaming media technology, you must download the entire media file before using it. [0003] Video streaming (Video Streaming), also known as video streaming data, refers to video data transmitted in the form of streaming media, for example: video files are transmitted on the network in the form of video streams, so that the video files can be As a steady and conti...
