Abstract

The invention discloses a method for uploading a video of a cloud video living broadcast platform. The method comprises the steps of firstly receiving video data acquired by a camera through a local proxy and carrying out video quality adjustment, uploading and local data caching tasks based on a comprehensive video value which is stored locally; and secondly, receiving video data uploaded by a local proxy server through a cloud server, live-broadcasting the video data online for a user to watch in response to a user request, and meanwhile, updating the comprehensive video value and feeding back the updated comprehensive video data to the local proxy server for sequencing of the video data in the next time. Correspondingly, the invention also discloses a corresponding system. According to the method and the system for uploading the video of the cloud video living broadcast platform, the transmission efficiency of high-value video data is fully increased, the use of a current bandwidth is enabled to be more reasonable and more efficient, meanwhile, video live broadcast requirements of different users are satisfied, and user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of online live broadcasting on a cloud video live broadcast platform, and more specifically relates to a video upload system and method for a cloud video live broadcast platform. Background technique [0002] When it is necessary to upload the real-time video data of multiple cameras under the LAN to the server, the upload bandwidth from the LAN to the WAN is often limited, resulting in unsmooth playback when providing live broadcast services to users. [0003] In order to further solve the problem of limited upload bandwidth, at present, the amount of uploaded data is generally reduced only by reducing the video quality, thereby alleviating the pressure of limited upload bandwidth. In this field, methods for reducing the amount of uploaded data mainly include reducing resolution and frame rate. Generally, the higher the resolution of the image, the more pixels it contains, the clearer the image, but the la...
