Technical Field

The invention relates to the technical field of video playing, in particular to a method and a system for pushing video slices.

Background

The prior art situation is as follows: at present, a screen sharing technology is mature day by day, a video stream pushing technology based on WIFI is mostly adopted in a commercial screen sharing technology, for example, the screen sharing of a computer is essentially realized by compressing desktop display of the computer into a video stream, then the video stream is transmitted to a playing terminal through the WIFI, and the video stream is played by the playing terminal, so that a screen sharing experience is brought to audiences. The existing technology is mature, and the wireless transmission replaces the traditional HDMI line transmission, so the installation and implementation are simple, and the wireless transmission is approved by a plurality of users. However, with the increase of WIFI routers, WIFI signal interference is more and more serious, and therefore, a screen video stream implemented by using the prior art is often jammed due to interference of WIFI signals, so that a screen operator has a feeling of screen sharing video delay, and a user has poor experience.

Disclosure of Invention

The object of the present invention is to provide: a method and system for video slice push streaming, which solves the problems mentioned above in the background art.

In order to achieve the above object, the present invention designs a method and a system for video slicing and stream pushing, which is characterized in that the method comprises a playing request acquisition module, a video slicing module, a video stream pushing module, a playing state sending module, and a playing state monitoring module; the video slicing module slices the requested video according to a fixed length, the video streaming module pushes the video slice to the request address, and the playing module plays the slice.

Further, after the play request module obtains the play request, the video slicing module slices the requested video according to a fixed length, and sequentially marks a slice number on the slice, the video streaming module pushes the video slice to the play request according to the slice number sequence, and the play module plays the slice according to the slice number.

Further, after the playing module plays the slice, the playing module sends the serial number of the played slice to the playing state monitoring module through the playing state sending module.

Further, when the state monitoring module acquires the slice number, the video playing state is acquired to be normal, when the state monitoring module does not acquire the slice number, the video playing state is acquired to be abnormal, and when the video playing state is normal, the state monitoring module records the current video slice number.

Furthermore, a time threshold is set in the state monitoring module, when the video playing state acquired by the state monitoring module is abnormal and the duration of the abnormal playing state reaches the time threshold, the state monitoring module sends a stream pushing stopping instruction to the video stream pushing module, and the video stream pushing module stops pushing streams to the playing module.

The invention has the beneficial effects that:

(1) when a fixed video is played, the video slice cannot cause the speed to slow down due to video loading;

(2) the video stream of the screen sharing type cannot be blocked because one or more frames are not acquired;

(3) after the video stream shared by the screens is temporarily blocked due to WIFI and the like, the video stream can directly jump to the latest video slice, and the experience brought to the user is greatly improved.
