Problems solved by technology

[0011] The introduction of a buffer queue with a dynamically changing cache depth can reduce the impact of network jitter on video transmission to a certain extent, but dynamic caching requires more storage resources, and dynamically adjusting the cache depth will occupy more computing resources. Both levels increase the burden on the receiving end

Embodiment Construction

[0025] The present invention will be further described below through specific examples, but it should be understood that these inventions are only used for more detailed description, and should not be construed as limiting the present invention in any form.

[0026] figure 1 , figure 2 It is a flow chart showing an embodiment of the live video broadcasting method of the present invention. Such as figure 1 As shown, the embodiment of the video live broadcast method of the present invention comprises the following steps: Step S1, receive video and store in video buffer; Step S2, detect the capacity of current data packet in the described buffer zone in real time; capacity is compared with the preset capacity threshold, if the capacity of the current packet acquired by the step S2 is less than the first threshold, then adjust the current playback speed to be less than the preset normal playback speed; If the capacity of the current data packet obtained in step S2 is greater t...

Abstract

The invention relates to a live video method and device in a network jittering environment, and the method comprises the following steps: receiving a video and storing the video in a video buffering region; detecting the capacity of a retention data package in the buffering region; comparing the capacity of the retention data package with a preset first threshold value, and judging the playing speed to be less than a preset normal playing speed according to the comparison results if the capacity of the retention data package is less than the preset first threshold value; The first threshold value is defined in a following mode: enabling the first threshold value to be B, and enabling the capacity of the video buffering region to be A, wherein B = A / 2-A*value, and the value is from 5% to 10%. Through the dynamic adjustment of the local playing speed at a local player terminal, the method reduces the adverse impact on video playing and watching experiences from network jittering, thereby improving the user experience.

Description

Technical field: [0001] The invention belongs to the field of network video playback, and in particular relates to a video live broadcast method and device in a network jitter environment. Background technique: [0002] With the Internet entering thousands of households, online video broadcasting has become a form of online communication that people love to see. Regardless of whether it is a mobile phone or a computer, the idea of ​​sharing on the Internet is deeply rooted in the hearts of the people, and the themes and contents of live webcasts are extremely rich, forming a situation where the demand for live video broadcasts is large and wide. [0003] However, the existing network quality cannot always meet the needs of online video live broadcast. One of the typical manifestations of unstable network quality is network jitter. Network jitter is defined as the maximum absolute value of the difference in the arrival delays of adjacent packets in the network. The differe...
