Therefore, the video quality detection after video transcoding is now There are pain points in technology.
基于此，在本申请中，提供了一种视频处理方法，本申请同时涉及一种视频处理装置，一种计算设备，以及一种计算机可读存储介质，在下面的实施例中逐一进行详细说明。Based on this, in the present application, a video processing method is provided. The present application also relates to a video processing apparatus, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one. .
参见图1，图1示出了根据本申请一实施例提供的一种视频处理方法的流程图，具体包括以下步骤：Referring to FIG. 1, FIG. 1 shows a flowchart of a video processing method provided according to an embodiment of the present application, which specifically includes the following steps:
步骤102：基于预设视频规则生成包括多个视频帧的初始视频，其中，每个视频帧均包含至少一个数量逐帧递增的测试对象。Step 102: Generate an initial video including a plurality of video frames based on a preset video rule, wherein each video frame includes at least one test object whose number increases frame by frame.
本申请实施例提供的视频处理方法应用于对视频转码系统的质量检测场景中，首先基于用户需求生成特殊的初始视频，然后将生成的初始视频输入待质量检测的视频转码系统中，通过对比检测转码前的初始视频与转码后的转码视频，判断转码前的初始视频与转码后的转码视频是否有差异，从而确定视频转码系统是否存在转码质量问题，例如若转码前的初始视频与转码后的转码视频没有差异，则说明视频转码系统不存在转码质量问题，转码是成功的；若转码前的初始视频与转码后的转码视频存在差异，则说明视频转码系统存在转码质量问题，转码可能存在丢帧或者掉帧等问题，那么需要对视频转码系统进行修复。The video processing method provided by the embodiment of the present application is applied to a quality detection scenario of a video transcoding system. First, a special initial video is generated based on user requirements, and then the generated initial video is input into the video transcoding system to be quality detected, and the Compare and detect the initial video before transcoding and the transcoded video after transcoding, and determine whether there is a difference between the initial video before transcoding and the transcoded video after transcoding, so as to determine whether there is a transcoding quality problem in the video transcoding system, such as If there is no difference between the initial video before transcoding and the transcoded video after transcoding, it means that there is no transcoding quality problem in the video transcoding system, and the transcoding is successful; If there is a difference in the transcoded video, it means that the video transcoding system has transcoding quality problems, and the transcoding may have problems such as frame loss or frame drop, so the video transcoding system needs to be repaired.
其中，预设视频规则可以理解为用户需求，例如用户需求为想要生成包括多个底图为白色的视频帧的初始视频，又或者用户需求为想要生成包括多个底图为黑色的视频帧的初始视频等，具体实施时，预设视频规则可以根据实际应用进行设置，本申请对此不做任何限定。The preset video rules can be understood as user requirements. For example, the user requirement is to generate an initial video including multiple video frames with white base images, or the user requirement is to generate a video including multiple black background images. The initial video of the frame, etc., during specific implementation, the preset video rules can be set according to the actual application, which is not limited in this application.
具体的，所述基于预设视频规则生成包括多个视频帧的初始视频，包括：Specifically, generating an initial video including multiple video frames based on preset video rules includes:
基于预设视频规则生成包括多个由第一像素的底图和第二像素的测试对象组成的视频帧的初始视频，其中，所述第一像素和所述第二像素的相似度小于等于预设相似度阈值。An initial video including a plurality of video frames consisting of a base image of a first pixel and a test object of a second pixel is generated based on a preset video rule, wherein the similarity of the first pixel and the second pixel is less than or equal to a predetermined Set the similarity threshold.
其中，第一像素和第二像素的像素值不同，且第一像素和第二像素的像素值的相似度小于等于预设相似度阈值；即可以理解为第一像素为白色的情况下，第二像素则为与白色的第一像素反差较大的黑色、紫色或者绿色等等。Wherein, the pixel values of the first pixel and the second pixel are different, and the similarity of the pixel values of the first pixel and the second pixel is less than or equal to the preset similarity threshold; that is, it can be understood that when the first pixel is white, the first pixel is white. The two pixels are black, purple, or green, etc., which have a greater contrast with the first pixel of white.
举例说明，若第一像素为白色，第二像素为黑色，那么基于预设视频规则生成包括多个由第一像素的底图和第二像素的测试对象组成的视频帧的初始视频，可以理解为基于预设视频规则生成多个由白色的底图和黑色的测试对象组成的视频帧的初始视频。For example, if the first pixel is white and the second pixel is black, then based on the preset video rule, an initial video including a plurality of video frames consisting of the base image of the first pixel and the test object of the second pixel is generated, it can be understood that An initial video for generating multiple video frames consisting of a white basemap and black test objects based on preset video rules.
其中，测试对象包括但不限于任何形状的测试块，例如正方形、圆形或者长方形的黑色测试块。Wherein, the test objects include but are not limited to test blocks of any shape, such as square, circular or rectangular black test blocks.
参见图2，图2示出了根据本申请一实施例提供的一种视频处理方法中初始视频的一个视频帧的示意图。Referring to FIG. 2, FIG. 2 shows a schematic diagram of a video frame of an initial video in a video processing method provided according to an embodiment of the present application.
图2为初始视频中的一个视频帧的示意图，该视频帧由白色的底图和黑色的长方形测试块组成，其中，该黑色的长方形测试块即为上述的测试对象。FIG. 2 is a schematic diagram of a video frame in the initial video. The video frame is composed of a white base image and a black rectangular test block, wherein the black rectangular test block is the above-mentioned test object.
本申请实施例中，通过像素值反差较大的底图和测试对象生成视频帧，再由多个此种视频帧组成初始视频，在后续对初始视频的每个视频帧中的测试对象的数量进行统计时，可以方便快速的提取出每个视频中颜色反差较大的测试对象，避免测试对象与底图的颜色较为相近时，无法很准确的查找到测试对象的轮廓，无法实现测试对象的准确获取。In the embodiment of the present application, a video frame is generated from a base image with a large pixel value contrast and a test object, and then an initial video is composed of a plurality of such video frames. When performing statistics, it is convenient and quick to extract the test objects with large color contrast in each video, so as to avoid the inability to accurately find the outline of the test object when the color of the test object and the base image are relatively similar, and it is impossible to realize the detection of the test object. Accurately obtain.
具体实施时，基于预设规则生成的初始视频中包括多个视频帧，每个视频帧由颜色反差较大的底图和测试对象组成，且每个视频帧中的测试对象的数量呈线性递增，例如若初始视频中包括3个视频帧：视频帧1、视频帧2以及视频帧3，那么在视频帧1中包括10个测试对象的情况下，视频帧2中则包括11个测试对象，视频帧3中包括12个测试对象；即初始视频的每个视频帧中包含的测试对象的数量是根据该初始视频的每个视频帧的排列顺序逐帧递增的。During specific implementation, the initial video generated based on the preset rules includes a plurality of video frames, each video frame is composed of a base image with large color contrast and a test object, and the number of test objects in each video frame increases linearly For example, if the initial video includes 3 video frames: video frame 1,
参见图3，图3示出了根据本申请一实施例提供的一种视频处理方法中初始视频的多个视频帧的示意图。Referring to FIG. 3 , FIG. 3 shows a schematic diagram of multiple video frames of an initial video in a video processing method provided according to an embodiment of the present application.
图3的初始视频中包括视频帧1、视频帧2以及视频帧3，其中，视频帧1中包括10个测试对象，视频帧2中包括11个测试对象，视频帧3中包括12个测试对象。The initial video of FIG. 3 includes video frame 1,
具体的，为了便于对每个视频帧中的测试对象进行提取，每个视频帧中的测试对象可以统一排列在视频帧的一个固定位置，当然实际应用中也不限定于此种排列，也可以将每个视频帧中的测试对象分别排列在不同的位置，例如将视频帧1中的测试对象排列在视频帧1的左上角，将视频帧2中的测试对象排列在视频帧2的右上角，将视频帧3中的测试对象排列在视频帧3的中间等。Specifically, in order to facilitate the extraction of the test objects in each video frame, the test objects in each video frame can be uniformly arranged in a fixed position of the video frame. Of course, the actual application is not limited to this arrangement. Arrange the test objects in each video frame in different positions, for example, arrange the test objects in video frame 1 in the upper left corner of video frame 1, and arrange the test objects in
具体的，所述基于预设视频规则生成包括多个视频帧的初始视频之后，还包括：Specifically, after the initial video including multiple video frames is generated based on the preset video rules, the method further includes:
在所述初始视频的每个视频帧的预设位置设置一个测试对象的数量展示区；A quantity display area of a test object is set at the preset position of each video frame of the initial video;
将所述初始视频的每个视频帧包含的测试对象的数量放置在所述数量展示区。The number of test objects contained in each video frame of the initial video is placed in the number display area.
其中，数量展示区可以理解为在初始视频的每个视频帧的预设位置设置的一个数字水印，使用数字水印的目的是为了方便人们识别观看到每个视频帧中包含的测试对象的数量，与在每个视频帧中设置测试对象不同，每个视频帧中包含的测试对象是为了方便机器识别统计的，在具体实施时，由于测试对象是用数字像素表示颜色的，那么具体统计时计算机可以直接统计每个视频帧中包含的第二像素(如黑色像素)的个数即可以获得每个视频帧的测试对象的数量。Among them, the quantity display area can be understood as a digital watermark set at the preset position of each video frame of the initial video. The purpose of using the digital watermark is to facilitate people to identify and watch the number of test objects contained in each video frame. Different from setting the test object in each video frame, the test object contained in each video frame is for the convenience of machine identification and statistics. During the specific implementation, since the test object is represented by digital pixels, the computer The number of test objects in each video frame can be obtained by directly counting the number of second pixels (eg, black pixels) included in each video frame.
实际应用中，为了方便的对初始视频的每个视频帧中的测试对象的数量进行获取，可以在初始视频的每个视频帧的预设位置设置一个测试对象的数量展示区，然后将初始视频的每个视频帧包含的测试对象的数量方式在该数量展示区进行展示，其中，预设位置可以为每个视频帧的任意位置，例如四个角或者是中间区域均可。为了避免数量展示区对测试对象进行遮挡，可以将测试对象和数量展示区分别设置在每个视频帧的不同位置，例如将测试对象排列在视频帧的左上角，将数量展示区放置在视频帧的右上角等。In practical applications, in order to conveniently obtain the number of test objects in each video frame of the initial video, a display area for the number of test objects can be set at the preset position of each video frame of the initial video, and then the initial video The quantity of the test objects contained in each video frame of , is displayed in the quantity display area, wherein the preset position can be any position of each video frame, such as the four corners or the middle area. In order to avoid the occlusion of the test object by the quantity display area, you can set the test object and the quantity display area at different positions of each video frame, for example, arrange the test object in the upper left corner of the video frame, and place the quantity display area in the video frame. upper right corner, etc.
其中，数量展示区放置的是初始视频的每个视频帧中包含的测试对象的数量，沿用上例，视频帧1的数量展示区放置的是视频帧1中包含的测试对象的数量10，视频帧2的数量展示区放置的是视频帧2中包含的测试对象的数量11，视频帧3的数量展示区放置的是视频帧3中包含的测试对象的数量12。Among them, the number display area is placed in the number of test objects contained in each video frame of the initial video. Following the above example, the number display area of video frame 1 is placed in the number of test objects contained in video frame 1. The number of 10, the video The
参见图4，图4示出了根据本申请一实施例提供的一种视频处理方法中初始视频的每个视频帧中数量展示区的示意图。Referring to FIG. 4, FIG. 4 shows a schematic diagram of a quantity display area in each video frame of an initial video in a video processing method provided according to an embodiment of the present application.
图4的初始视频中包括视频帧1、视频帧2以及视频帧3，其中，视频帧1中包括10个测试对象，视频帧2中包括11个测试对象，视频帧3中包括12个测试对象。The initial video of FIG. 4 includes video frame 1,
其中，测试对象均排列在每个视频帧的左上角，而每个视频帧的右上角均设置一个数量展示区，用于展示每个视频帧中包括的测试对象的数量；即视频帧1的右上角的数量展示区放置的是视频帧1中包含的测试对象的数量10，视频帧2的右上角的数量展示区放置的是视频帧2中包含的测试对象的数量11，视频帧3的右上角的数量展示区放置的是视频帧3中包含的测试对象的数量12。Among them, the test objects are arranged in the upper left corner of each video frame, and a quantity display area is set in the upper right corner of each video frame to display the number of test objects included in each video frame; The quantity display area in the upper right corner places the
本申请实施例中，为了更加方便的对初始视频中每个视频帧包含的测试对象的数量进行确定，可以在初始视频的每个视频帧中设置一个测试对象的数量展示区，将初始视频的每个视频帧包含的测试对象的数量放置且展示在对应的数量展示区。In the embodiment of the present application, in order to more conveniently determine the number of test objects contained in each video frame in the initial video, a display area for the number of test objects may be set in each video frame of the initial video, and the The number of test objects contained in each video frame is placed and displayed in the corresponding number display area.
步骤104：将所述初始视频发送至预设视频转码系统进行视频转码，并接收所述视频转码系统返回的转码视频。Step 104: Send the initial video to a preset video transcoding system for video transcoding, and receive the transcoded video returned by the video transcoding system.
其中，预设视频转码系统包括任意一个待进行转码质量测试的视频转码系统。Wherein, the preset video transcoding system includes any video transcoding system to be tested for transcoding quality.
具体的，生成包括多个视频帧的初始视频之后，将该初始视频发送至特定的需要进行转码质量测试的视频转码系统中进行转码，然后接收该视频转码系统返回的对初始视频转码后生成的转码视频。Specifically, after generating an initial video including multiple video frames, the initial video is sent to a specific video transcoding system that needs to be tested for transcoding quality for transcoding, and then the initial video returned by the video transcoding system is received. The transcoded video generated after transcoding.
具体实施时，所述将所述初始视频发送至预设视频转码系统进行视频转码，并接收所述视频转码系统返回的转码视频之后，还包括：During specific implementation, after the initial video is sent to a preset video transcoding system for video transcoding, and the transcoded video returned by the video transcoding system is received, the method further includes:
通过预设识别算法识别所述转码视频中每个视频帧在所述数量展示区展示的测试对象的数量。Identify the number of test objects displayed in the number display area for each video frame in the transcoded video by using a preset identification algorithm.
实际应用中，由于初始视频的每个视频帧的数量展示区均携带有该视频帧包含的测试对象的数量，且转码过程中，该数量展示区以及该数量展示区放置的测试对象的数量一般不会因为转码而丢失，或者出现乱码等，那么在转码后，转码视频的每个视频帧中也存在数量展示区，且每个数量展示区包含有一个测试对象的数量。In practical applications, since the number display area of each video frame of the initial video carries the number of test objects contained in the video frame, and during the transcoding process, the number of display areas and the number of test objects placed in the number display area are Generally, it will not be lost or garbled due to transcoding. After transcoding, there is also a quantity display area in each video frame of the transcoded video, and each quantity display area contains the quantity of a test object.
因此在获得转码视频后，可以通过预设识别算法(例如OCR识别算法)识别出转码视频中每个视频帧在数量展示区展示的测试对象的数量。Therefore, after obtaining the transcoded video, the number of test objects displayed in the quantity display area for each video frame in the transcoded video can be identified through a preset recognition algorithm (eg, an OCR recognition algorithm).
本申请实施例中，通过识别算法识别出转码视频中每个视频帧在数量展示区展示的测试对象的数量，后续可以基于该转码视频中每个视频帧在数量展示区展示的测试对象的数量与初始视频的每个视频帧在数量展示区展示的测试对象的数量进行比较，从而准确的确定初始视频在转码成转码视频后是否发生了丢帧或者掉帧的情况。In the embodiment of the present application, the number of test objects displayed in the quantity display area for each video frame in the transcoded video is identified by an identification algorithm, and subsequent test objects can be displayed in the quantity display area based on each video frame in the transcoded video. The number of each video frame of the original video is compared with the number of test objects displayed in the quantity display area, so as to accurately determine whether the original video has dropped or dropped frames after transcoding into transcoded video.
步骤106：按照所述转码视频中视频帧的排列顺序，确定所述转码视频中每个视频帧包含的测试对象的数量。Step 106: Determine the number of test objects included in each video frame in the transcoded video according to the sequence of video frames in the transcoded video.
具体的，获得转码视频后，按照转码视频中视频帧的排列顺序，确定该转码视频中每个视频帧包含的测试对象的数量。Specifically, after the transcoded video is obtained, the number of test objects contained in each video frame in the transcoded video is determined according to the arrangement order of the video frames in the transcoded video.
具体实施时，获得转码视频后，需要按照转码视频中视频帧的排列顺序，通过计算机统计出每个视频帧中包含的测试对象的数量，而非通过识别算法对转码视频的每个视频帧中数量展示区中的测试对象的数量进行识别。In the specific implementation, after obtaining the transcoded video, it is necessary to count the number of test objects contained in each video frame through the computer according to the arrangement order of the video frames in the transcoded video, instead of using the identification algorithm to identify each frame of the transcoded video. The number of test objects in the number display area in the video frame is identified.
由于初始视频转码的过程中可能会出现丢帧或者掉帧的现象，因此转码后的转码视频中的视频帧可能会出现错乱，此时重新统计转码视频的每个视频帧中包含的测试对象的数量会使得后续的比对更加准确。Since frames may be dropped or dropped during the initial video transcoding process, the video frames in the transcoded video may be chaotic. The number of test subjects will make subsequent alignments more accurate.
步骤108：将所述初始视频中每个视频帧包含的测试对象的数量与所述转码视频中每个视频帧包含的测试对象的数量进行比对，以确定所述初始视频的转码结果。Step 108: compare the number of test objects contained in each video frame in the initial video with the number of test objects contained in each video frame in the transcoded video to determine the transcoding result of the initial video .
其中，根据初始视频中每个视频帧包含的测试对象的数量与转码视频中每个视频帧包含的测试对象的数量进行比对，以确定出初始视频的转码结果至少包括两种情况可以实现，一种是通过计算机统计出来的测试对象的数量进行比对，另一种可以直接通过每个视频帧的数量展示区展示的测试对象的数量进行比对，具体实现方式如下所述：Wherein, according to the number of test objects contained in each video frame in the initial video and the number of test objects contained in each video frame in the transcoded video, it is determined that the transcoding result of the initial video includes at least two cases. One is to compare the number of test objects counted by the computer, and the other is to directly compare the number of test objects displayed in the number display area of each video frame. The specific implementation methods are as follows:
所述将所述初始视频中每个视频帧包含的测试对象的数量与所述转码视频中每个视频帧包含的测试对象的数量进行比对，以确定所述初始视频的转码结果，包括：Described comparing the number of test objects included in each video frame in the initial video with the number of test objects included in each video frame in the transcoded video, to determine the transcoding result of the initial video, include:
将所述初始视频中每个视频帧包含的测试对象的数量逐帧排列，以形成第一数量序列，以及将所述转码视频中每个视频帧包含的测试对象的数量逐帧排列，以形成第二数量序列；The number of test objects included in each video frame in the initial video is arranged frame by frame to form a first sequence of numbers, and the number of test objects included in each video frame in the transcoded video is arranged frame by frame, with forming a second sequence of quantities;
将所述第一数量序列与所述第二数量序列进行比对，在所述第一数量序列与所述第二数量序列全部匹配的情况下，确定所述初始视频转码成功。The first quantity sequence is compared with the second quantity sequence, and in the case that the first quantity sequence and the second quantity sequence all match, it is determined that the initial video transcoding is successful.
具体的，将初始视频中每个视频帧包含的测试对象的数量按照初始视频中所有视频帧的排列顺序逐帧排列，以形成第一数量序列。Specifically, the number of test objects included in each video frame in the initial video is arranged frame by frame according to the arrangement order of all video frames in the initial video, to form a first quantity sequence.
沿用上例，将初始视频中每个视频帧包含的测试对象的数量按照初始视频中所有视频帧的排列顺序逐帧排列，形成的第一数量序列为【10、11、12】。Following the above example, the number of test objects contained in each video frame in the initial video is arranged frame by frame according to the arrangement order of all video frames in the initial video, and the first number sequence formed is [10, 11, 12].
同时，将转码视频中每个视频帧包含的测试对象的数量按照转码视频中所有视频帧的排列顺序逐帧排列，以形成第二数量序列。At the same time, the number of test objects contained in each video frame in the transcoded video is arranged frame by frame according to the arrangement sequence of all video frames in the transcoded video, to form a second quantity sequence.
例如，转码视频仍包括三个顺序排列的视频帧：视频帧1、视频帧2和视频帧3，那么将转码视频中每个视频帧包含的测试对象的数量按照转码视频中所有视频帧的排列顺序逐帧排列，形成的第二数量序列为【10、11、12】。For example, the transcoded video still includes three video frames arranged in sequence: video frame 1,
那么将第一数量序列与第二数量序列进行比对，可以确定第一数量序列和第二数量序列全部匹配，此时则可以确定初始视频转码成功，而初始视频转码成功则可以说明当前的视频转码系统的转码质量良好。Then, by comparing the first quantity sequence with the second quantity sequence, it can be determined that the first quantity sequence and the second quantity sequence all match. At this time, it can be determined that the initial video transcoding is successful, and the success of the initial video transcoding can indicate that the current The transcoding quality of the video transcoding system is good.
本申请实施例中，通过将统计的初始视频的每个视频帧包含的测试对象的数量与统计的转码后的转码视频的每个视频帧包含的测试对象的数量进行比对，根据比对结果可以快速准确的判断出初始视频的转码结果是否正确，提升用户体验。In the embodiment of the present application, by comparing the number of test objects contained in each video frame of the initial video with the number of test objects contained in each video frame of the transcoded transcoded video, according to the comparison The result can be quickly and accurately judged whether the transcoding result of the initial video is correct, and the user experience can be improved.

在所述验证视频帧满足预设转码条件的情况下，确定所述初始视频转码成功。In the case that the verification video frame satisfies the preset transcoding condition, it is determined that the initial video transcoding is successful.
其中，预设转码条件根据实际应用进行设置，本申请对此不做任何限定，例如预设转码条件为视频帧1可以有重复帧或者是视频帧2在转码的过程中可以丢帧。The preset transcoding condition is set according to the actual application, and this application does not make any limitation on this. For example, the preset transcoding condition is that video frame 1 may have repeated frames or
沿用上例，若转码视频包括顺序排列的三个视频帧：视频帧1和视频帧3，将转码视频中每个视频帧包含的测试对象的数量按照转码视频中所有视频帧的排列顺序逐帧排列，形成的第二数量序列为【10、12、11】；那么第一数量序列【10、11、12】与第二数量序列【10、12】则不匹配，此时确定的第二数量序列中与第一数量序列不匹配的测试对象的数量为11，则不匹配的测试对象的数量对应的视频帧为初始视频中的视频帧2，那么视频帧2则为验证视频帧。Following the above example, if the transcoded video includes three video frames arranged in sequence: video frame 1 and video frame 3, the number of test objects contained in each video frame in the transcoded video is arranged according to the arrangement of all video frames in the transcoded video. The sequence is arranged frame by frame, and the second quantity sequence formed is [10, 12, 11]; then the first quantity sequence [10, 11, 12] does not match the second quantity sequence [10, 12]. The number of test objects that do not match the first number sequence in the second quantity sequence is 11, then the video frame corresponding to the number of unmatched test objects is the
若预设转码条件为视频帧2需要在视频转码的过程丢帧，根据该预设转码条件可以确定该验证视频帧满足该预设转码条件，此时也可以说明初始视频转码成功。If the preset transcoding condition is that
本说明书实施例中，由于具体的视频转码场景不同，一些特殊视频转码场景中为了视频特效等需求会允许在视频转码的过程中出现丢帧、掉帧等情况的发生，因此在第一数量序列和第二数量序列不匹配的情况下，还需要基于具体应用场景中的预设转码条件再次验证初始视频是否转码成功，以扩大本申请提供的视频处理方法的应用场景，提升用户使用体验。In the embodiments of this specification, due to different specific video transcoding scenarios, some special video transcoding scenarios may allow frame loss, frame drop, etc. to occur during the video transcoding process for the needs of video special effects. In the case where the first quantity sequence and the second quantity sequence do not match, it is also necessary to re-verify whether the initial video is successfully transcoded based on the preset transcoding conditions in the specific application scenario, so as to expand the application scenarios of the video processing method provided in this application and improve the User experience.

那么将第一数量序列与第二数量序列进行比对，可以确定第一数量序列和第二数量序列不匹配，此时则可以确定初始视频转码失败，即转码之后的视频帧2和视频帧3的顺序发生了错乱，则可以说明当前的视频转码系统的转码质量不是很好，后续需要对视频转码系统进行修复，并且通过此种方式可以根据不匹配的数字快速定位到出错的问题视频帧，在对视频转码系统进行修复时，可以基于出错的问题视频帧进行问题分析。Then, by comparing the first quantity sequence with the second quantity sequence, it can be determined that the first quantity sequence and the second quantity sequence do not match.

那么将第一数量序列与第二数量序列进行比对，可以确定第一数量序列和第二数量序列不匹配，此时则可以确定初始视频转码失败，即转码之后的视频帧2丢失，视频帧1产生了重复帧，此时这种视频帧重复转码的情况与视频帧转码出现视频帧数错乱的情况不同，这种情况下，转码后的视频播放时，不仅会造成视频画面前后关联度较差，且还会由于重复视频帧产生卡顿感。因此对于此种情况，也需要对视频转码系统进行修复，并且通过上述方式根据不匹配的数字快速定位到出错的问题视频帧，在对视频转码系统进行修复时，可以基于出错的问题视频帧进行问题分析。Then, by comparing the first quantity sequence with the second quantity sequence, it can be determined that the first quantity sequence and the second quantity sequence do not match.
