At present, for the test of video playing, mostly test through the manual work, through manual operation naked eye observation, the video of playing is the condition that there is the broadcast exception enough, if: black screen, frame loss or discontinuous play, etc. Or, the method is partially used for automatic testing, video recording or software screen capture is performed on display screen content through a camera, then the video recording content or screen capture image of the camera is analyzed, whether abnormal conditions exist in a played video is often limited due to conditions such as artificial patience degree or energy consumption, and the situation that a testing effect is poor is caused, and the method for video recording or software screen capture of the content played by video playing has influence depending on external environments, such as light conditions and other factors, so that a testing result is influenced.
Based on this, the video playing processing method, the video playing processing device and the electronic device provided by the embodiment of the invention can complete the test in the video playing process and complete the judgment of the playing state, thereby realizing the technical effect of a fully automatic test.
To facilitate understanding of the present embodiment, a detailed description is first given of a processing method for video playing disclosed in the present embodiment.
An embodiment of the present invention provides a video playing processing method, such as a flowchart of a video playing processing method shown in fig. 1, where the method includes the following steps:
step S102, responding to a video playing operation acted on a video testing device, and triggering the video testing device to play a video code stream file of a source to be tested;
specifically, a script can be preset to realize video playing operation of the video test equipment, and the script is used to play the video code stream file of the source to be tested, so that the video code stream file is played.
Step S104, responding to the video acquisition operation acted on the video acquisition equipment, triggering the video acquisition equipment to acquire a video code stream file of a source to be tested, which is played by the video test equipment, and generating an acquired video stream corresponding to the video code stream file of the source to be tested;
specifically, after the script triggers the playing of the video code stream file, the acquisition card is used for acquiring the video code stream file of the source to be tested, which is played by the video test equipment, to generate a corresponding acquired video stream, and the acquired video stream is output to the test station.
Step S106, obtaining an original video file of a source to be tested;
specifically, an original video file of a source to be tested is stored in a testing station.
Step S108, calculating the frame similarity of the original video file and the collected video stream frame by frame;
specifically, an acquired video stream acquired by an acquisition card is split into frames, which are named as acquisition frames; splitting a test source video into frames, and naming the frames as source video frames; comparing the collected frame with the corresponding source video frame, wherein the comparison algorithm adopts a histogram method, the collected frame and the corresponding source video frame are used as two input images, histograms H1 and H2 are obtained through calculation, and the histograms are normalized to the same scale space; then, the similarity degree of the two histograms can be obtained by calculating the distance between the H1 and the H2, and then the similarity degree of the images is compared, so that the basis of the video playing detection assertion is provided.
Since video is a continuous image, if the frame rate is a video stream of M frames per second and 30 seconds in duration, there are N =30M frame data in total. When the video is played, the acquisition card acquires the video, and the acquired N frame data is compared with the corresponding frame of the N frames of the test source video from the 1 st frame to the N frame from the beginning of playing, so that the abnormity of the video playing is detected.

if the frame similarity falls into the similarity threshold range corresponding to the video playing failure, determining that the playing state of the video testing equipment is the video playing failure, and generating testing assertion information of the video playing failure;
if the frame similarity falls into the similarity threshold range corresponding to the video playing abnormity, determining that the playing state of the video testing equipment is the video playing abnormity, and generating testing assertion information of the video playing abnormity;
and if the frame similarity falls into the similarity threshold range corresponding to the video playing normality, determining that the playing state of the video testing equipment is the video playing normality, and generating testing assertion information of the video playing normality.
6. The method of claim 1, wherein the step of triggering the video test device to play the video bitstream file of the source to be tested comprises:
and triggering the video test equipment to play the video code stream file of the source to be tested through a preset first control script.
7. The method of claim 1, wherein the step of triggering the video capture device to capture the video bitstream file of the source to be tested played by the video test device comprises:
and triggering the video acquisition equipment to acquire the video code stream file of the source to be tested, which is played by the video test equipment, through a preset second control script.
8. A processing apparatus for video playback, the apparatus comprising:
the first trigger module is used for responding to a video playing operation acted on the video test equipment and triggering the video test equipment to play a video code stream file of a source to be tested;
the second trigger module is used for responding to the video acquisition operation acted on the video acquisition equipment, triggering the video acquisition equipment to acquire the video code stream file of the source to be tested, which is played by the video test equipment, and generating an acquired video stream corresponding to the video code stream file of the source to be tested;
the acquisition module is used for acquiring the original video file of the source to be tested;
the calculation module is used for calculating the frame similarity of the original video file and the acquired video stream frame by frame;
and the testing module is used for testing and asserting the playing state of the video testing equipment based on the frame similarity.
9. An electronic device comprising a processor and a memory, the memory storing computer-executable instructions executable by the processor, the processor executing the computer-executable instructions to implement the method of any one of claims 1 to 7.
10. A computer readable storage medium having stored thereon machine executable instructions which, when invoked and executed by a processor, cause the processor to carry out the method of any of claims 1 to 7.
