Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a video playing detection method, a video playing detection device and electronic equipment, aiming at the problem of low testing efficiency of the existing testing scheme of radio frequency playing performance indexes.
Fig. 1 is a schematic flow chart of a video play detection method according to an embodiment of the present invention. The method specifically comprises the following steps:
in this step, in the recording process of the target recorded video, the first video is played through the video application to be tested.
It should be noted that the target recorded video can be obtained through a screen recording function of the electronic device.
102, framing the target recorded video to obtain continuous multi-frame images;
in this step, a preset framing tool can be used to frame the target recorded video. Optionally, the preset framing tool is FFmpeg or OpenCV.
It should be noted that the color coding method of the target recorded video is a YUV color coding method. Where Y denotes luminance, and U and V denote chrominance.
Because the video stream of the target recorded video is a YUV stream, the image after framing the target recorded video is also an image in a YUV color space.
103, identifying the first image and the first frame image according to the multiple frame images, wherein the first frame image is determined based on the brightness change amplitude between the adjacent frame images of the multiple frame images;
in this step, as can be seen from the previous step, the image of the target recorded video after framing is an image in YUV color space, and the brightness change amplitude between adjacent frame images can be obtained by extracting the brightness Y component of the image. Specifically, the difference between the luminance mean values of the adjacent frame images may be determined as the luminance change amplitude between the adjacent frame images.
It should be noted that the human eye is much more sensitive to the luminance component than to the color component. The video is composed of images which are continuous in time, and because the image inside the target recorded video is an image in a YUV color space, compared with a mode of simultaneously transmitting three primary colors of RGB coding, the method for separating a brightness signal Y and a chrominance signal U, V of the YUV image reduces the bandwidth occupied by transmission. Compared with the complexity of RGB color value traversal calculation and OCR recognition algorithm, the method improves the efficiency of first frame image recognition by using the sequential storage mode of the Y components of the YUV image.
And 104, determining a time interval between the first image and the first frame image, and taking the time interval as the video playing starting duration of the first video.
The video playing detection method comprises the steps of obtaining a target recorded video, wherein the target recorded video is a target video segment comprising a first image and a first frame image of the first video, and the first image is a frame image corresponding to the first video when the first video is triggered to be played; framing the target recorded video to obtain continuous multi-frame images; identifying the first image and the first frame image according to the multi-frame images, wherein the first frame image is determined based on the brightness change amplitude between the adjacent frame images of the multi-frame images; the time interval between the first image and the first frame image is determined, and the time interval is used as the video playing starting time of the first video, so that the brightness characteristics of the images are utilized to identify the first frame image, the complexity of a first frame image identification algorithm is reduced, the image identification efficiency is improved, in addition, the test process does not depend on the codes of a video application program, the test process is simple, non-technical testers can also execute the test, and the test efficiency is improved.
The embodiment of the invention adopts an automatic script mode to record the target recorded video, wherein the automatic script can adopt a user interface UI automatic script test framework, such as UiAutomator, Apium and the like. That is, the target recorded video is acquired in an automatic script manner. As an optional implementation manner, in step 101 of the method according to the embodiment of the present invention, the acquiring a target recorded video includes:
after the screen recording is started, triggering and playing the first video;
it should be noted that the electronic device executing the method has a screen recording function.
And when the recording duration reaches the preset duration, stopping recording the screen, and storing the recorded video as the target recorded video.
Here, the preset duration is a preset duration, generally 5 seconds, and may be adjusted according to actual conditions to ensure that the first frame image is loaded.
It should be noted that after the electronic device starts the screen recording, the video recording is performed at a preset screen recording frame rate, wherein in the recording process, a first image corresponding to the first video and a first frame image of the first video are triggered to be played and recorded.
It should be noted that the detection method of the present embodiment is driven by an automated script in the whole process, and does not depend on the code of a video application program, so that a non-technical tester can also perform a test.
As an alternative implementation, step 102 may include:
acquiring a screen recording frame rate of the target recorded video;
optionally, when the target recorded video is obtained through the screen recording, the screen recording parameters are saved at the same time. Here, the screen recording parameters include, but are not limited to: the screen recording frame rate and the screen recording frame number.
Cutting the target recorded video, and storing the video content in the video playing area as the cut recorded video;
it should be noted that this step is performed to avoid the interference of the images of the first frame of image in the target recorded video except for the images of other areas in the video playing area.
Here, the video playback area is a playback area of the first video. That is, when recording a video, the video playing area of the first video is played through the video application to be tested.
And framing the cut recorded video according to the screen recording frame rate to obtain continuous multi-frame images.
The cut recorded video can be framed according to the recording frame rate through an FFmpeg tool, and continuous multi-frame images are obtained. Alternatively, the multiple frame images are saved in a jpg format in chronological order.
Here, the continuous multi-frame image refers to a temporally continuous multi-frame image.
As an optional implementation manner, in step 103, identifying the first image according to the multiple frames of images may include:
traversing the multi-frame images for image recognition according to the time sequence of the multi-frame image display during video playing;
here, since the multi-frame images are temporally continuous multi-frame images, there is a chronological order.
And determining the current frame image as the first image when the current frame image is identified to have the preset image characteristic which triggers the playing of the first video.
It should be noted that the preset image feature is an image feature of an image corresponding to a pre-stored trigger play video. For example, the status flag of the play control button is a characteristic of the play flag. Specifically, the identified feature is not played in the image features corresponding to the image before the first image.
It should be noted that the multiple frames of images have respective corresponding frame numbers in chronological order, and when a first image is identified, the frame number corresponding to the first image is acquired. Alternatively, after the first image is identified, a frame number corresponding to the first image, for example, number 1, is assigned.
As an optional implementation manner, in the method step 103, identifying the first frame image according to the multiple frame images may include:
after the first image is identified, traversing frame images behind the first image to extract brightness components to obtain a brightness mean value of an ith frame image and a brightness mean value of an (i + 1) th frame image in the frame images behind the first image, wherein the (i + 1) th frame image is a current frame image, i is not less than 1, and i is a positive integer;
it should be noted that there are three YUV sampling methods, YUV4:4:4, YUV4:2:2, and YUV4:2: 0. The storage mode of the YUV stream is closely related to the sampling mode, wherein the storage mode includes YV12, YU12, NV12, NV21 and the like. As shown in fig. 2, the schematic diagram of the storage method of YV12 and fig. 3, the schematic diagram of the storage method of NV12 show that the luminance Y component is stored continuously at the start address regardless of the storage method, so that the extracted Y component can be read continuously and efficiently. Here, the storage of YUV is different from RGB in that data of each point of RGB is continuously stored together, and YUV reduces U, V component space in order to save space.
Calculating the brightness change amplitude between the ith frame image and the (i + 1) th frame image;
specifically, a difference value between a luminance component of an ith frame image and a luminance component of an (i + 1) th frame image is calculated to obtain a luminance change amplitude between the ith frame image and the (i + 1) th frame image.
Under the condition that the brightness change amplitude is smaller than a preset threshold value, adding 1 to i, and returning to the step of calculating the brightness change amplitude between the ith frame image and the (i + 1) th frame image until the brightness change amplitude is larger than the preset threshold value;
for example, after the first image is recognized, the luminance component of the 1 st frame image after the first image is extracted, the luminance average value of the 1 st frame image is calculated, the luminance component of the 2 nd frame image is extracted, and the luminance average value of the 2 nd frame image is calculated. And then, calculating the difference value between the brightness mean value of the 1 st frame image and the brightness mean value of the 2 nd frame image to obtain a brightness change amplitude value between the brightness mean value of the 1 st frame image and the brightness mean value of the 2 nd frame image. And then, if the brightness change amplitude value between the brightness mean value of the 1 st frame image and the brightness mean value of the 2 nd frame image is smaller than a preset threshold value, adding 1 to i, calculating the brightness change amplitude value between the 2 nd frame image and the 3 rd frame image, and repeating the steps until the brightness change amplitude value between the current frame image and the previous frame image is larger than the preset threshold value.
After adding 1 to i, extracting the luminance component of the 3 rd frame image, calculating the luminance average value of the 3 rd frame image, and then calculating the luminance change amplitude between the 2 nd frame image and the 3 rd frame image.
And under the condition that the brightness change amplitude is larger than a preset threshold value, determining the (i + 1) th frame image as the first frame image.
In this implementation manner, it should be noted that, before the first frame of video is played, the video playing area is usually a black screen, an advertisement, a video logo, and the like, and the image change of this picture area is small, so the brightness change amplitude of adjacent frames is also small, and the brightness change amplitude between adjacent frames is compared with a preset threshold value to serve as a determination mode for the occurrence of the first frame of video.
Further, in order to solve the problem of how to obtain the preset threshold in this embodiment, as an optional implementation manner, before obtaining the target recorded video, the method further includes:
determining the maximum value of the brightness change amplitude between adjacent frame images in the multi-frame loaded image before the first frame image of the first video is played as the preset threshold value;
specifically, before testing, screenshot is carried out on a picture before playing a first frame image of a first video, only an image in a video playing area is reserved, a brightness Y component of the image is extracted, a brightness mean value is obtained through calculation, and the maximum value of the brightness change amplitude of adjacent frames is taken as a preset threshold value.
Or obtaining a preset threshold value according to the corresponding relation between the video application and the threshold value, wherein the preset threshold value corresponds to the video application playing the first video.
Here, in the same video application, the frames before the first frame of the video is played are basically the same, so the same threshold value is used for testing different video moments.
