As an alternative embodiment, a target video is obtained, where the target video may be a video for performing audio-visual synchronous detection, and the target video includes a target image frame carrying marker information and target audio data at a target position of a play time axis. Namely, the target video has marking information on the image frame and the audio data played at the preset time point, and the marking information is used for marking the target image frame and the target audio data to acquire the time of the target image frame and the target audio data to detect the actual time of the target image frame and the target video data which should be simultaneously appeared. By marking the target video with the marking information, the detection result of the synchronization of the sound and the picture can be obtained subsequently, so that the detection is more convenient and quick, and the detection convenience is improved.
Alternatively, the above-mentioned mark information may be presented in various forms, such as words, arabic numerals, capital letters, lowercase letters, and the like, or in combination of various forms.

When multiple positions are considered, the setting of the target position may be performed in various ways. For example, the marking information is an arabic numeral, a numeral serial number may be sequentially added at predetermined time intervals, and for an image frame, the image frame with the numeral serial number appears every predetermined time (for example, 2s), which is 1, 2, 3, etc. respectively; for audio data, the number of the numbered counts of mandarin voice occurring every predetermined time (e.g., 2s) is 1, 2, 3. For another example, since the time of the target video may be longer, the number sequence numbers may be sequentially added at increasing time intervals, for the image frames, that is, for the image frames, one frame of image frame with the number sequence number appears at every increasing time interval (for example, the time interval is 2s, the appearance time is 2s, 6s, 12s …), which is 1, 2, 3, etc. respectively; for audio data, the number of the numbered counts of mandarin human voice occurring every incremental time interval (e.g., 2s time interval, 2s, 6s, 12s …), is 1, 2, 3. And are not limited herein. As long as the time at which the target image frame and the target audio data occur can be regularly presented. By setting the target position, corresponding selection can be performed according to different network conditions or other actual conditions and requirements, so that the detection is more reasonable and more efficient.
As an alternative embodiment, acquiring a first time of playing the target image frame when playing the target video according to the mark information includes: identifying a plurality of image frames of a played target video, and determining the image frame with mark information displayed in the plurality of image frames as a target image frame; and determining the playing time of the playing target image frame as a first time. And recording the mark information displayed in the target image frame and the first time for displaying the target image frame for subsequent processing. When the marking information is a number, i.e., an arabic number, it is determined that an image frame including the number in the plurality of image frames is a target image frame. When the position is multiple and the mark information is a sequentially increasing number sequence number, the plurality of image frames including the number sequence number in the plurality of image frames are determined to be a plurality of target image frames, namely the image frame including the number 1, the image frame including the number 2 and the like. Recording mark information, a first time corresponding to the mark information. And respectively recording a plurality of first times of playing a plurality of target image frames carrying the mark information when the target video is played, respectively calculating time differences with a plurality of second times of a plurality of target audio data, and detecting.
As an alternative embodiment, acquiring the second time when the target audio data is played while the target video is played according to the mark information includes: identifying audio data of a played target video, and determining part of audio data played with the mark information in the audio data as target audio data; and determining the playing time of the playing target audio data as a second time. And recording the mark information displayed in the target audio data and the second time for playing the target audio data for subsequent processing. And when the marking information is the digital serial number, determining that part of the audio data broadcasting the digital serial number in the audio data is the target audio data. When the positions are multiple and the marking information is sequentially increased number serial numbers, determining that multiple parts of audio data broadcasting the number serial numbers in the audio data are multiple target audio data, namely the part of audio data including broadcasting number 1, the part of audio data including broadcasting number 2, and the like. Recording mark information, and recording a second time corresponding to the mark information. And respectively calculating time differences with a plurality of first times of a plurality of target image frames according to a plurality of second times of playing a plurality of target audio data with mark information recorded respectively, and detecting.
It should be noted that, when the tag information is broadcasted by voice, the broadcasting time may be long, for example, when the number 1 is broadcasted, a long sound may be dragged, and therefore, the time for broadcasting the target audio data cannot be well determined. In this case, the duration for playing the target audio data may be determined, the target volume value may be selected from a plurality of volume values corresponding to the duration, the volume value may be acquired and marked in the form of volume pulses, and the second time may be calibrated. The target volume value may be the volume value when the sound is the highest, or may be other volume values, and may be defined by itself. Therefore, the time of the occurrence of the target audio data can be calibrated according to the duration and the target volume value, so that the second time can be determined more accurately.
As an alternative embodiment, the sound-picture synchronization result when the target video is played is determined according to the first time and the second time. The sound and picture synchronization result can be obtained by determining the time difference value between the first time and the second time and comparing the time difference value with the sound and picture synchronization standard. And under the condition that the time difference value is less than or equal to a first preset threshold value or greater than or equal to a second preset threshold value, determining that the sound and picture synchronization result of the target video is sound and picture synchronization. And under the condition that the time difference value is larger than a first preset threshold value or smaller than a second preset threshold value, determining that the sound and picture synchronization result of the target video is sound and picture asynchronization. The result of whether the sound and the picture are synchronized is obtained accurately. After the result of the sound-picture asynchronism is obtained, prompt information for prompting the sound-picture asynchronism of the target video can be displayed, and the image frame and the audio data of the target video can be adjusted according to the time difference between the first time and the second time.
It should be noted that, when the target position includes a plurality of target positions, that is, when the number of the target image frames carrying the tag information and the number of the target audio data are plural, the first time and the second time are respectively plural, where the number of the target image frames and the number of the target audio data are the same, and therefore, the number of the first time and the number of the second time which are correspondingly acquired should be the same. At this time, a plurality of time differences between the corresponding target image frames and the corresponding target audio data are acquired. After obtaining the plurality of time difference values, corresponding settings may be performed according to actual applications and scenes so as to determine the sound-picture synchronization result, for example, an average value may be calculated for the plurality of time difference values within a predetermined time period, and image frames and audio data of the adjustment target video may be calibrated. The time difference value can be adjusted when the time difference value is larger than the first preset threshold value or smaller than the second preset threshold value, and the method is suitable for strict and stricter scenes, so that adjustment can be performed according to the reality to enhance the impression and hearing experience of people.
It should be noted that, when the sound and picture synchronous detection is performed in the present application, there is also a case that, in the case of a weak network, when a frame jam or a sound break occurs, it may not be detected, or target image frames and/or target audio data carrying tag information are missed to be detected, that is, when a plurality of target positions are included, the number of target image frames and target audio data carrying tag information is multiple and the same, and the number of corresponding first time and second time obtained should also be the same, but in some environments or situations, for example, the weak network, target image frames and/or target audio data carrying tag information cannot be detected, so some target image frames and/or target audio data carrying tag information may not be detected, and the number of obtained first time and second time may be missing, or the number of first times and the number of second times are not the same. In this case, the correspondence relationship of the plurality of marker information corresponding to the plurality of target image frames under recording and the plurality of marker information corresponding to the plurality of target audio data may be determined; determining the missing mark information and the target position of the mark information under the condition that the corresponding relation is that the mark information is missing in a plurality of mark information corresponding to a plurality of detected target image frames and/or a plurality of mark information corresponding to a plurality of detected target audio data; and deleting the mark information of the target image frame or the target audio data detected at the recorded target position, and the first time when the detected target image frame appears or the second time when the target audio data appears, namely when determining the sound-picture synchronization result when playing the target video according to the first time and the second time, not considering that both sides are missing and one side has missing. The invalid value can be accurately filtered according to a plurality of mark information corresponding to a plurality of target image frames and a plurality of mark information corresponding to a plurality of target audio data after deletion operation and a plurality of time difference values between a plurality of first time and a plurality of second time, so that the method is suitable for testing the sound picture asynchronization of a normal network and a weak network of various audio and video applications, and can distinguish the missing data from the complete data effectively and inefficiently, thereby improving the accuracy of the detection result.
