Problems solved by technology
For a decoding device, one network port usually needs to correspond to multiple output ports. When large video services need to be processed, there is still a large gap between the actual transmission capacity of the bandwidth and the demand, and it is easy to cause video data to be displayed on the wall. When the screen freezes

Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0030] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not ...

The embodiment of the invention discloses a video processing method, device, electronic equipment and medium. The method includes: determining the target video service from at least two video services if the code stream switching trigger event is recognized; and determining the code stream switching control information of the target video service; sending the code stream switching to the management device control information, so that the management device switches and sends the code stream of the target video service according to the code stream switching control information; and receives the switched code stream of the target video service sent by the management device. Using this application scheme, the video code stream from the streaming end can be controlled to avoid the problem of insufficient network transmission bandwidth caused by the excessive bit rate of the received video code stream, which solves the problem of large traffic The problem of video freeze caused by insufficient transmission bandwidth when the video stream is uploaded to the wall maximizes the use of decoding resources and network transmission resources.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of data transmission, and in particular, to a video processing method, device, electronic equipment, and medium. Background technique [0002] With the popularity of video walls and the higher and higher resolutions supported, more and more fields choose to use video walls to display video information. For example, in the field of surveillance, video walls are used to display surveillance video in real time. [0003] At present, in the case of increasingly strong display requirements and display capabilities, the transmission capacity of a single network port has been upgraded from 100M to Gigabit. For a decoding device, one network port usually needs to correspond to multiple output ports. When large video services need to be processed, there is still a large gap between the actual transmission capacity of the bandwidth and the demand, and it is easy to cause video data to be displaye...
