Embodiment 1

[0019] The present application provides a method for controlling the delay of a live video stream. The method can be applied to a client, and the client can be a terminal device used by a user. For example, the client may be a smart phone, a tablet computer, a desktop computer, a notebook computer, a smart wearable device (virtual reality glasses, a smart watch, etc.), a video-on-demand device, and the like. The client may also be software running on the above-mentioned terminal device. For example, the client may be a player running on a terminal device.

[0020] see figure 1 , the delay control method for live video streams provided in this application may include the following steps.

[0021] S1: Detect the current playback delay of the live video stream, and compare the current playback delay with the specified delay range. If the current playback delay is outside the specified delay range, set the current playback speed.

[0022] In this embodiment, the live video str...

Embodiment 2

[0033] see Figure 4 , the present application also provides a delay control device for live video streaming, the device comprising:

[0034] The playback speed setting unit is used to detect the current playback delay of the live video stream, and compare the current playback delay with the specified delay range, and when the current playback delay is outside the specified delay range case, set the current playback speed;

[0035] A double-speed playback duration determination unit, configured to determine the double-speed playback duration based on the current playback delay, the specified delay range, and the playback multiple speed;

[0036] The double-speed playback unit is configured to play the live video stream at the double-speed playback, and play the live video stream at a normal speed after the playback time at the double-speed playback reaches the double-speed playback duration.

[0037] In one embodiment, the live video stream is divided into multiple video sli...

Abstract

The invention discloses a time delay control method and device of live broadcasting video flows. The method comprises steps of detecting the current playing time delay of the live broadcasting video flows, comparing the current playing time delay and a designated time delay range, and in case that the current playing time delay is in the designated time delay range, setting the current playing speed multiplication; based on the current playing time delay, the designated time delay range and the playing speed multiplication, determining the speed multiplication playing duration; playing the live broadcasting video flows according to the playing speed multiplication, and after the duration of the playing according to the playing speed multiplication reaches the speed multiplication playing duration, according to the normal speed, playing the live broadcasting video flows. According to the invention, under the condition that watching experience of users is not affected, the playing time delay is controlled in a proper range.

Description

technical field [0001] The invention relates to the technical field of video playback, in particular to a delay control method and device for live video streaming. Background technique [0002] With the rise of the live broadcast industry, the playback technology of live video streams is also constantly evolving. Due to the strong real-time nature of live video streaming, the impact of playback delay on live video streaming is particularly significant. If the playback delay is too short, the live video stream may freeze due to network fluctuations and other reasons; if the playback delay is too long, it will affect the real-time performance of the live video stream. Therefore, when playing a live video stream at present, it is necessary to control the playback delay within a reasonable range. [0003] At present, the playback delay is usually maintained by discarding the live video stream data or pausing the live video stream. Specifically, if the current playback delay i...
