Abstract

The invention discloses a video transmission method and device. The method comprises following steps of receiving the video stream of a collected party; successively placing each video frame in the video stream in a cache queue; successively extracting and transmitting the video frame from the cache queue through a network; monitoring the length L of the video frame queue in the cache queue; if L is less than or equal to H, not deleting a frame, wherein the H is equal to the sum of the time length of a group of pictures GOP and a preset time offset value; if the L is more than the H and the frames of two GOPs exist in the cache queue, starting from the last P frame of the former GOP in the cache queue to delete one or multiple P frames until the L is enabled to be less than or equal to the H. Compared with the prior art, the technical solution provides a more effective method for discarding video frames; a user can fluently watch more video contents when the network condition is relatively poor; and the watching experience of the user is greatly optimized.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video transmission method and device. Background technique [0002] When a user watches a video over the Internet, even if it is reflected as "online viewing", it still needs to obtain data from the server that provides the video and download it locally to watch it. The speed is not enough, and the video data required for playback cannot be obtained within the time when the video is played at normal speed, resulting in stuttering. At this time, many video websites will remind users to use a video resolution format with lower definition, that is, a smaller amount of video data to watch, or to pause the video they are watching, and watch it after buffering enough video data. But the latter method is not suitable for watching live video, that is, it cannot meet the needs of users to watch videos in real time; the former method cannot provide users with better viewing effec...
