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

[0031] 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.

[0032] figure 1 , figure 2 It is a flow chart showing an embodiment of the live video broadcasting method of the present invention. like 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 than...

Abstract

The present invention relates to a video live broadcasting method and a device in a network jitter environment. The method comprises the steps of (S1) receiving a video and storing the video in a video buffer area, (S2) detecting the capacity of a retention data packet in the buffer area, (S3) comparing the capacity of the retention data packet and a preset capacity threshold, and adjusting a video playing speed according to a comparison result. Through dynamically adjusting the playing speed at a local player end, the negative impact of video playing viewing experience brought by network jitter is reduced, and thus a user experience is improved.

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...
