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 explained by specific examples below. However, it should be understood that these inventions are only used for more detailed and specific description, and should not be understood as limiting the present invention in any form.

[0032] figure 1 , figure 2 It is a flowchart showing an embodiment of the video live broadcast method of the present invention. Such as figure 1 As shown, the embodiment of the video live broadcast method of the present invention includes the following steps: step S1, receiving video and storing it in a video buffer; step S2, detecting the capacity of the current data packet in the buffer in real time; step S3, converting the current data packet Is compared with the preset capacity threshold, and if the capacity of the current data packet obtained in step S2 is less than the first threshold, then the current playback speed is adjusted to be less than the preset normal playback speed; If the capacity of the cu...

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, web video live broadcasting has become a popular form of online communication. Whether it is a mobile phone or a computer, the Internet's sharing thinking is deeply rooted in the hearts of the people, and the themes and content of the webcast are extremely rich, forming a situation where the demand for live video 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 delay of adjacent data packets in the network. The difference in delay between adjacent data packets reflects...
