Embodiment 1

[0034] figure 1 It is a schematic flowchart of a video transmission method provided by Embodiment 1 of the present invention. The method is applied to a video sending end, and is specifically applied to an application scenario in which the video sending end sends a video to a video server. See figure 2 A schematic diagram of a video transmission architecture is shown, specifically: Alice as the video sender transmits the video to be sent to the video server RTC_server through the network path Path1, and the video server RTC_server transmits the received video to the video receiver Bob through the network path Path2 . Preferably, in this embodiment, the video sending end may be a camera device used in the medical industry, and the video receiving end may be any electronic device with a video playback function such as a personal computer, a computer, a mobile phone, and a smart TV.

[0035] The technical solution provided in this embodiment is mainly aimed at how to ensure t...

Embodiment 2

[0052] image 3 It is a schematic flow diagram of a video transmission method provided by Embodiment 2 of the present invention. On the basis of the above embodiments, this embodiment further optimizes the solution. Specifically, if the real-time transmission of the video cannot be guaranteed after reducing the bit rate, then Further perform a frame drop operation on the target video, and reduce the frame rate of the target video through the frame drop operation, thereby reducing the amount of data transmitted per second, and achieving the purpose of real-time video transmission without greatly losing the image quality.

[0053] Such as image 3 Shown, described video transmission method comprises the steps:

[0054] Step 310, determine the current real-time network bandwidth.

[0055] Step 320, adjust the code rate of the video encoder according to the real-time network bandwidth and the preset expected network bandwidth.

[0056] Step 330, if the adjusted bit rate reaches...

Embodiment 3

[0088] Figure 5 A video transmission device provided in Embodiment 3 of the present invention, the device includes: a determination module 510, an adjustment module 520, a compression module 530 and a sending module 540;

[0089] Wherein, the determination module 510 is used to determine the current real-time network bandwidth; the adjustment module 520 is used to adjust the code rate of the video encoder according to the real-time network bandwidth and the preset expected network bandwidth; the compression module 530 is used to pass The video encoder compresses the target video based on the adjusted code rate to obtain the compressed target video; the sending module 540 is configured to send the compressed target video to the video server through the network, so that the video server Send the compressed target video to the video receiving end.

[0090] On the basis of the above technical solution, the adjusting module 520 is specifically configured to: reduce the bit rate o...

Abstract

The embodiment of the invention discloses a video transmission method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a current real-time network bandwidth; adjusting the code rate of a video encoder according to the real-time network bandwidth and a preset expected network bandwidth; performing compression processing on a target video based on the adjusted code rate through the video encoder to obtain a compressed target video; sending the compressed target video to a video server through a network, wherein the video server sends the compressed target video to the video receiving end. According to the mehtod disclosed in the technical scheme of the embodiment of the invention, the real-time transmission of the video between thevideo sending end and the video server is ensured, and the video picture quality can be ensured.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a video transmission method, device, electronic equipment, and storage medium. Background technique [0002] Real-time video transmission is widely used in all walks of life, and the network carrying video transmission may encounter abnormal conditions such as interference and congestion at any time. How to ensure the real-time transmission of video images even when the network transmission channel becomes poor? At present, there are various methods to deal with the above-mentioned problems. In practice, methods such as appropriately increasing the video transmission delay or reducing the video picture quality are used to deal with it. [0003] However, in the application scenarios such as remote consultation or remote control in the medical industry, the requirements for real-time video transmission and video image quality are very high, and the cou...
