Problems solved by technology

[0003] The Chinese patent application number 201410224695.1 proposes an automatic test method for on-demand video testing on different terminals, but does not mention the test of live broadcast. At the same time, the patent does not point out the special timeliness test method of live broadcast, that is, in the process of live broadcast, The timeliness of the live broadcast of different terminals needs to be guaranteed. In different network environments, the timeliness of the live broadcast is allowed to be delayed for a short time (depending on the demand for live broadcast delay, some game live broadcasts The regulation is 10s, and the live broadcast of some personal shows may be 30s, or even 60s, etc.)
If the delay period is exceeded, the experience of live broadcast will be greatly reduced.

Embodiment 1

[0060] According to an embodiment of the present invention, an embodiment of a live video test method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0061] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, figure 1 It is a block diagram of the hardware structure of the computer terminal according to the live video test method of the embodiment of the present invention. like figure 1 As shown, the computer terminal 100 may include one or more (only one is shown in the figure) processor 102 (the proce...

Embodiment approach

[0084] As an optional implementation, the method also includes:

[0085] Step S100: Classify the live video according to delay requirements; set a predetermined time for each type of live video according to the classification of the live video.

[0086] The categories of live video include: games, personal shows, competitions and performances.

[0087] The predetermined value is 80%.

[0088]For example, the main purpose of the present invention is to judge whether the delay time of a certain live video under different terminals is within the allowable range. Since the front-end adopts different playback methods for different devices and different operating systems during live video broadcasting, it is necessary to verify whether the live video can be played within the specified delay range in different network environments and different terminal playback methods. During the allowed time, the live video content will be played normally. By taking screenshots of each key fram...

Embodiment 2

[0090] like Figure 5 As shown, the present invention also provides a live video test system, including:

[0091] The first obtaining module is used to obtain the first key frame of the original live video stream, and obtain the second key frame within the predetermined time before the moment when the first key frame appears;

[0092] The second acquisition module is used to extract the image of the live video stream played on the terminal at the moment when the first key frame appears, and obtain the test image;

[0093] A third acquiring module, configured to acquire a first similarity between the test image and the first key frame, and acquire a second similarity between the test image and the second key frame;

[0094] A judging module, configured to judge that the terminal plays normally when any one of the first similarity and the second similarity is not less than a predetermined value.

[0095] As a preferred implementation manner, the first obtaining module is furth...

Abstract

The invention discloses a video live broadcast test method and system. The method comprises the steps of obtaining a first key frame of an original live broadcast video stream and obtaining a second key frame within predetermined time before the appearing moment of the first key frame; extracting an image of a live broadcast video stream played by a terminal at the appearing moment of the first key frame, thereby obtaining a test image; obtaining a first similarity between the test image and the first key frame and obtaining a first similarity between the test image and the second key frame; and judging that the terminal plays normally if any one of the first similarity and the second similarity is not smaller than a predetermined value. According to the method and the system, through comparison of images of key frame screenshots of video key frame time points of the same live broadcast channel at the terminal and a server side, whether the problem of influencing the user experience due to overlong delay occurs in the live broadcast process of the terminal or not is judged.

Description

technical field [0001] The invention relates to the technical field of video playback, in particular to a method and system for testing live video. Background technique [0002] With the rapid development of the mobile Internet, the integration of multiple screens, and the rapid increase of live video terminals, the test work of live broadcast players has developed from a simple PC terminal platform to various terminals including mobile phones, tablets, TVs, and boxes. During the live video broadcast, during the persistent playback process, the delay of the live broadcast will be superimposed with the buffering time depending on the network environment of the client. At this time, the player will correct the delay time in real time when playing the live broadcast. At this time, the delay test for some important live broadcasts is particularly important. [0003] The Chinese patent application number 201410224695.1 proposes an automatic test method for on-demand video test...
