Problems solved by technology

However, although this method saves transmission bandwidth, due to the fixed method of video fusion, the picture generated after video fusion is fixed and cannot be split flexibly, which will prevent the client from performing personalized rendering of the fused video. For example, the client Unable to zoom in on a certain sub-picture in the fusion screen or change the layout position of several video screens, etc.
In the prior art, if you want to change one or several sub-pictures in the fusion picture, you can only realize the layout of the fusion picture at the encoding end, and for the uniform layout change, the picture layout of all receiving ends is the same, which cannot be realized for each client. Personalized Video Screen Layout

Embodiment 1

[0033] image 3 It is a flow chart of a video transmission method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation when multi-channel video fusion transmission is realized. The method can be executed by a video transmission device, and the device can use hardware and / or software, and can usually be configured in electronic equipment.

[0034] A video transmission method, applied to a server end, specifically includes the following steps:

[0035] S310. Merge at least two channels of video into a fusion video according to the first preset picture layout, and generate a transmission code stream of the fusion video.

[0036] Among them, the server side can be understood as a computer system that can provide certain services to other machines in the network. The first preset screen layout can be understood as a screen layout preset on the server side. The staff on the server side conceived, organized, and configured the display f...

Embodiment 2

[0052] Figure 4 It is a flow chart of a video output method provided by Embodiment 2 of the present invention. This embodiment is further refined on the basis of the foregoing embodiments. Specifically, the following steps may be included:

[0053] Specifically, according to the first preset picture layout, at least two channels of video may be merged into a fusion video, and a transmission code stream of the fusion video may be generated. The specific steps can be from S410 to S440:

[0054] S410. Obtain the video interface binding relationship, main interface and sub-interface of the first preset screen layout

[0055] Wherein, the video interface binding relationship can be understood as the corresponding relationship between the main interface and the user terminal display interface, that is, the corresponding relationship between the video viewed by the user terminal and the location of the video. The main interface can be understood as a video screen formed after the...

Embodiment 3

[0089] Figure 5 It is a flow chart of a video transmission method provided by Embodiment 3 of the present invention. This embodiment is applicable to the situation when multi-channel video fusion transmission is realized. The method can be executed by a video transmission device, and the device can use hardware and / or software, and can usually be configured in electronic equipment.

[0090] A video transmission method, applied to a client, specifically includes the following steps:

[0091] S510. Acquire the transmission code stream at the server side, and generate a restored fusion video corresponding to the transmission code stream.

[0092] Wherein, restoring the fused video can be understood as restoring the fused video.

[0093] In this embodiment, the client can obtain the transport code stream transmitted by the server, and the additional enhanced information field of the transport code stream at this time includes the location information of each video. Wherein, th...

Abstract

The invention discloses a video transmission method, electronic equipment and a storage medium. The method is applied to a server side, and comprises the following steps: merging at least two paths of videos into a fused video according to a first preset picture layout, and generating a transmission code stream of the fused video; adding the position information of each video in the fused video to the transmission code stream; and transmitting the transmission code stream to a client. According to the embodiment of the invention, the position information of each video in the fused video is added to the transmission code stream, and then the transmission code stream is transmitted to the client, so that the fused transmission of the multi-channel video is realized, the bandwidth occupation of the transmission of the multi-channel video is reduced, and the personalized layout of the multi-channel video is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a video transmission method, electronic equipment, and a storage medium. Background technique [0002] With the development of Internet technology, multi-channel video has been widely used. Currently, common application scenarios include announcement broadcasting, live broadcast, emergency command, and online education. In order to save transmission bandwidth and reduce the playback pressure of the client, multi-channel video usually requires video fusion to change the multi-channel video into a single-channel video. However, although this method saves transmission bandwidth, due to the fixed method of video fusion, the picture generated after video fusion is fixed and cannot be split flexibly, which will prevent the client from performing personalized rendering of the fused video. For example, the client It is not possible to zoom in on a cer...
