Network video fluent playing control method based on a streaming media technology

Abstract

The invention discloses a network video fluent playing control method based on a streaming media technology, which comprises the following steps of: setting a high threshold value H and a low threshold value L in a received data buffer area module, and when the queue length (taking a frame as a unit) of a buffer area is between [L, H], adopting a normal playing rate, and enabling the display timeof each frame to be a normal length; according to the method, the playing time is determined based on the probability model, and when the playing time is smaller than L, the display time of each frameis prolonged by adopting a smaller playing rate; and when the playing rate is greater than H, the display time of each frame is shortened by adopting a relatively high playing rate. According to theinvention, the problem that the network is unstable is solved; the technical problems that the actual frame rate and the ideal frame rate are inconsistent and the network video playing is not smooth due to the fact that the video data transmission time transmitted by the network fluctuates, the time for arriving at a receiver and the time under the ideal condition generate a difference, and the clock source used by a common camera is not high in precision and generates timestamp drift are solved.

Description

technical field [0001] The invention belongs to the technical field of video monitoring and multimedia playing, and in particular relates to a method for controlling smooth playing of network video. Background technique [0002] With the rapid development of streaming media technology, it is very common to use mobile terminal devices to browse streaming media resources on websites, which greatly enriches people's daily life. [0003] Streaming Media (Streaming Media) refers to the media format played on the Internet in a streaming manner. In a streaming system, users don't have to wait until the entire file is downloaded to see the content as in non-streaming playback, but only need a few seconds or tens of seconds of start-up delay. Use the corresponding player on the user's computer or mobile terminal device to play the compressed video or audio and other streaming media files, and the remaining parts will continue to be downloaded synchronously until the playback is comp...

AI Technical Summary

Problems solved by technology

When the number of frames in the buffer is greater than the threshold value, the display time is shortened and the playback speed is accelerated; when it is lower than the threshold value, the display time is increased and the playback speed is reduced, but this solution cannot guarantee smooth video playback
