Abstract

Disclosed are a video transmission method and device. The method comprises: receiving a video stream of a collecting party, successively placing video frames in the video stream into a cache queue, and successively extracting the video frames from the cache queue and transmitting the video frames through a network; monitoring the length L of a video frame queue in the cache queue; if L is less than or equal to H, not deleting a frame, H being equal to a sum of a time length of one group of pictures (GOP) and a preset time offset value; and if L is greater than H and frames belonging to two GOPs exist in the cache queue, deleting one or more P frames starting from a last P frame of a previous GOP in the cache queue, until L is less than or equal to H. Compared with the prior art, the technical solution provides a more effective method for discarding a video frame, so that a user can watch more video contents more smoothly when the network condition is poor, thereby greatly optimizing watching experience of the user.

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...
