In addition, the scheme can cover all the calories meeting the preset standard, and compared with the existing scheme, the accuracy and the precision of the processing result are better.
Wherein, the obtaining the katon start point in the target video from the previous video according to the last frame of the previous video and the reference frame of the corresponding time point in the source video comprises: confirming whether the front-segment video is a minimum segmentation unit or not under the condition that the similarity between the last frame and the reference frame is smaller than a first threshold value; taking the last frame as a katon starting point in a target video under the condition that the front-segment video is a minimum segmentation unit; and under the condition that the front-segment video is not the minimum segmentation unit, taking the front-segment video as a new target video, and returning to the step of segmenting the target video into the front-segment video and the rear-segment video until a starting point of the pause is obtained.
In this case, it is considered that there is a pause in the front-end video.
In an embodiment of the present invention, the acquiring a katon start point in the target video from the later video according to the last frame of the previous video and the reference frame of the corresponding time point in the source video includes: confirming whether the rear video is a minimum segmentation unit or not under the condition that the similarity between the last frame and the reference frame is greater than or equal to a first threshold value; and under the condition that the front-segment video is not the minimum segmentation unit, taking the rear-segment video as a new target video, and returning to the step of segmenting the target video into the front-segment video and the rear-segment video until a starting point of the pause is obtained.
In this case, it is assumed that there is no pause in the front video and there is pause in the rear video.
Correspondingly, the obtaining a pause end point corresponding to the pause start point in the target video according to the pause start point includes: and acquiring a pause end point corresponding to the pause starting point in the target video according to the next frame corresponding to the pause starting point in the source video.
In this embodiment of the present invention, the obtaining a katon start point in the target video from the later video according to the last frame of the previous video and the reference frame of the corresponding time point in the source video further includes: taking the starting point of the back video as the starting point of the pause in the target video under the condition that the back video is the minimum segmentation unit; the obtaining of the pause end point corresponding to the pause start point in the target video according to the pause start point includes: and taking an end point of the back-segment video corresponding to the start point of the back-segment video as a pause end point corresponding to the pause start point in the target video.
It can also be understood that the latter video is actually a frame of video, and a stuck is present in the latter video, then the stuck is the frame.
Further, before the target video is divided into a front-segment video and a rear-segment video, the method further includes: acquiring a first difference value between a second time length corresponding to the target video and a first time length corresponding to the source video; and determining that the target video is stuck if the first difference is greater than or equal to a second threshold.
The second threshold may be set according to an actual demand for the duration of the stuck time, for example, the default setting is 0.1 second.
In this embodiment of the present invention, the obtaining the pause information of the target video according to the pause starting point and the pause ending point includes: obtaining a stuck frame number and a stuck image according to the stuck starting point and the stuck ending point; obtaining the pause duration according to the pause frame number and the frame rate used by the actual playing of the source video; and acquiring the pause information of the target video according to at least one of the pause frame number, the pause image and the pause time.
Further, after obtaining the hiton information of the target video according to the hiton starting point and the hiton ending point, the method further includes: acquiring a second difference value between a second time length corresponding to the target video and the pause time length in the pause information; and under the condition that the second difference value is larger than the first time length corresponding to the source video, taking the video after the pause end point in the target video as a new target video, taking the video after the frame corresponding to the pause end point in the source video as a new source video, and returning to the step of dividing the target video into a front-segment video and a rear-segment video.
It is also understood that the above jam detection operation (similar to the present jam determination flow) may be executed again when another jam still exists after the present jam (corresponding to the jam time length) is confirmed.
The data processing method provided by the embodiment of the present invention is illustrated below.
In view of the above technical problems, an embodiment of the present invention provides a data processing method, which can be specifically implemented as a video stuck detection method: on the basis of judging the stuck time through the comparison of the playing time (corresponding to the first time and the second time), the video is segmented, and the clipped last frame is determined frame by frame only by comparing and positioning the segmented last frame of the video to the first frame of the stuck time, so that the workload required to be compared is reduced, and the comparison efficiency is improved. On the basis, the scheme can cover all the stuck times meeting the preset standard, and compared with a sampling detection method, the accuracy and the precision of the result are better.
The scheme can also be understood as providing a video pause detection and measurement method, which judges whether the target video is paused or not based on the time length comparison of the source video and the target video, quickly determines the starting point and the ending point of the pause by carrying out multiple segmentation and frame comparison on the source video and the target video, and further calculates the information of the pause times, the time length and the like.
Specifically, the scheme provided by the embodiment of the present invention may be specifically as shown in fig. 2 (the minimum partition unit takes the minimum partitionable frame as an example), and includes:
step 21: acquiring a video to be played (a source video), and determining the playing time (corresponding to the first time);
it can also be understood that the video to be detected is obtained as the source video, and the time length required by playing the video is determined.
Step 22: playing a video, and recording the video (a target video) according to the actually played frame rate to obtain the actually played time length;
it can also be understood that the video is played, and the video is recorded according to the frame rate of the actual playing, so as to obtain the target video playing time length (the actual playing time length, corresponding to the second time length) for detecting whether the jam exists.
Step 23: comparing the playing time lengths (a source video VS target video), if the playing time length of the source video is equal to the actual playing time length of the target video, entering step 24, and if the playing time length of the source video is less than the actual playing time length of the target video, entering step 25;
specifically, the playing duration of the source video is compared with the actual playing duration of the target video, if the playing duration of the source video is not equal, it is determined that the video is stuck, the video segmentation process is performed, that is, step 25 is performed, and then step 26 is performed.
Regarding "play duration comparison (source video VS target video)", the following may be specifically: and determining whether the first difference between the actual playing time length of the target video and the playing time length of the source video is greater than or equal to a second threshold value, wherein the second threshold value can be set by itself, such as default to 0.1 s.
Step 24: determining that the time lengths are the same and no jamming exists;
that is, if the playing time length of the source video is equal to the actual playing time length of the target video, the target video is considered to be not blocked, and the judgment is finished.
Step 25: determining that the target video is blocked when the time lengths are different;
step 26: dividing a target video according to a certain standard, and acquiring the duration, the initial frame and the end frame of a divided video block;
step 27: comparing whether the end frame of the first half section of the target video (namely the front section of the target video) is the same as the frame of the corresponding time of the source video; if yes, go to step 28; if not, go to step 211;
step 28: the video block (i.e. the first half video) is not blocked and is not compared; entering step 29;
step 29: judging whether the second half video (namely the second video) is a minimum partitionable frame (corresponding to the minimum partition unit); if yes, go to step 210, if no, return to step 26;
step 210: recording a time point corresponding to the frame, and taking the frame as a starting point and an end point of the pause; entering step 213 (or not entering step 213, directly calculating the time length of the current pause according to the frame rate and the frame number actually used by the video playing, and recording the obtained relevant information of the pause, but not limited to this);
the above can be understood in particular as: the target video is divided into two parts (the division is not necessarily half) according to certain rules and standards (such as time point halving, or other clue prompts of the monitored playing process (such as plot development)). And comparing the similarity between the last frame (namely the last frame) of the former part (corresponding to the front-segment video) and the frame (namely the reference frame) of the source video at the same time point, if the similarity reaches a preset standard (namely the first threshold), determining that the first half part does not have pause, continuously dividing the second half part (corresponding to the rear-segment video) and comparing the last frame of the same time point (namely comparing the last frame of the divided video with the frame of the source video at the corresponding time point) until finding the initial frame of the pause.
Specifically, the method comprises the following steps: in the case of no stuck in the first half, next, it can be determined first whether the second half is a minimum divisible frame (corresponding to the minimum partition unit); if not, the latter half is taken as a new target video, the source video part corresponding to the latter half is taken as a new source video (that is, the starting point of the latter half is taken as the starting frame of the new target video, and the ending point is taken as the ending frame of the new target video, the frame corresponding to the time point in the source video with the starting point of the latter half is taken as the starting frame of the new source video, and the ending point of the source video is taken as the ending frame of the new source video), and the procedure returns to step 26.
Step 211: determining that the video is blocked, and judging whether the first half section of the video is the minimum divisible frame; if yes, go to step 212, otherwise, go back to step 26;
step 212: recording a time point corresponding to the frame, taking the next frame of the source video as an end point to compare the frames, and comparing the next frame of the target video frame by frame until the comparison frame of the source video is matched; and taking the matched frame as a stuck end point.
Regarding "recording the time point corresponding to the frame, taking the next frame of the source video as the end point comparison frame, and comparing the next frame of the target video frame by frame until the comparison frame of the source video is matched", it can be understood as: recording the time point in the target video, and acquiring a next frame in the source video as an end frame according to the time point; and matching the end frame with the target video until the end frame is matched with the target video to obtain the end point of the section of pause.
That is: if the ending frame of the first half video of the target video is not matched with the frame of the corresponding time of the source video (not meeting the preset standard, namely not identical), the first half part is considered to be blocked, the first half part is continuously divided, the last frame comparison at the same time point is continuously carried out, and step 28 or step 211 is executed according to the comparison result until the starting frame of the blockage at the time is found.
In the embodiment of the present invention, the "minimum partitionable frame" may be understood as: the minimum unit of the division is a frame, and specifically, in implementation, if the similarity between two frames before and after the division is lower than a first threshold, the frame is not the minimum divisible frame, and if the similarity is equal to or higher than the first threshold, the frame is the minimum divisible frame.
In the embodiment of the present invention, after determining the beginning frame of the mortgage, the next frame of the beginning frame of the mortgage of the source video may be taken, and compared with the next frame of the beginning frame of the mortgage of the target video frame by frame until a frame with a similarity reaching the standard is found, and the frame is recorded as the last frame of the mortgage (i.e., the end point of the mortgage or the end frame of the mortgage).
In embodiments of the present invention, the last frame may span multiple partitioned video blocks (i.e., the last frame may span multiple partitioned video blocks).
Step 213: and calculating the time length of the current pause according to the frame rate and the frame number.
Specifically, the frame number of the start frame and the frame number of the end frame may be calculated, and the duration of the current pause may be calculated according to the frame rate of the video during actual playing.
Step 214: subtracting the pause time length from the actual video playing time length to obtain a difference value (corresponding to the second difference value);
step 215: comparing the difference value with the source video time length (namely the source video playing time length); if the difference is greater than the source video duration, go to step 216; if the difference is equal to the source video duration, go to step 217;
that is, whether the difference is greater than the source video duration is determined, if yes, step 216 is performed, and if not, step 217 is performed;
step 216: and determining that the difference is longer than the time length of the source video and the target video is still stuck, taking the next frame of the last frame of the stuck as a starting point (serving as the starting point of a new target video), and returning to the step 26 (continuing to perform segmentation matching).
Specifically, the difference obtained by subtracting the current pause time length from the target video time length (i.e. the actual playing time length of the target video) is compared with the source video time length. If the former is higher than the latter, the phenomenon of pause still exists, the processes of cutting, comparing, judging and calculating are continued from the next frame of the last frame of the pause to the last frame of the target video as a starting point until the pause does not exist.
The scheme can detect the pause of the video during actual playing.
Step 217: determining that the difference is equal to the source video time length, ending the operation and storing information if no other card is in place;
regarding "saving information", what is specifically saved may be katon-related information, such as: a stuck time duration, a stuck time point, a stuck frame, etc.;
that is, if the target video duration is equal to the source video duration (there is no case of being greater than the source video duration), it is determined that there is no stuck.
Subsequently, information such as the calendar morton time point, the picture (frame image), the duration and the like can be saved. This information can be used for subsequent reporting.
As can be seen from the above, in the scheme provided in the embodiment of the present invention, a source video for reference comparison and a target video for actual playing are first constructed, and the target video is recorded in the process of playing the source video. And comparing the time lengths of the source video and the target video, and judging that the video is stuck if the time length of the target video is greater than that of the source video. Cutting the video according to a halving thought, and comparing the last frame of the cut front half video with the frame of the corresponding time point of the source video; if the two video segments are the same, the video is paused in the second half segment, and the second half segment is continuously divided; if the difference is different, the video in the first half section is blocked, and the video in the first half section is continuously divided until the first frame of the blockage is found. And subsequently, comparing the next frame corresponding to the first frame of the pause in the source video with the later frame of the target video frame by frame until the last frame of the pause is found. Then, the duration between the first frame and the last frame of the calton can be calculated as the calton duration. And comparing the difference of the target video minus the pause time with the time of the source video, if the difference is still greater than the time of the source video, judging that the pause still exists, and continuing to divide. If the two are the same, the fact that the card is not in existence is judged, and the comparison is finished.
It is also understood that the solution provided by the embodiments of the present invention involves: starting from a target video, when the existence of the pause is judged through time length comparison, firstly, the target video is divided, and then whether the video is a pause starting point (namely a pause starting frame) is judged by comparing the last frame of the cut previous video with the frame of the corresponding time point in the source video; after the start point of the pause is determined, the method continues from the next frame in the source video, finds a corresponding matching frame (i.e., the end point of the pause, which may also be referred to as the end frame of the pause) in the target video, and then calculates the pause duration by the number of frames between the two detected frames (i.e., the start frame and the end frame of the pause) in the target video. In the embodiment of the present invention, the divided video may be continuously split into a plurality of segments (at least two segments) according to the time length, which is not limited herein.
In summary, the scheme provided by the embodiment of the invention can realize that:
1) the playing time lengths of the source video and the target video are firstly compared to judge whether the video is stuck. The advantage of adding this judgment link is to avoid comparison under the condition that the target video is not jammed, and reduce the consumption of evaluation resources.
2) By carrying out frame comparison after the video is segmented and starting the comparison from the first time of pause, the comparison resource of the normal playing part is avoided, and the workload of frame comparison is reduced.
3) After the first frame of the Kadun is determined, the next frame of the source video is selected to be gradually compared with the frame of the target video, so that the segmentation of the source video and the comparison of the frames are reduced as much as possible, and the workload of comparison and comparison is reduced.
4) After the primary jamming is determined, whether the jamming exists or not is judged continuously through time comparison, and the segmentation and comparison are carried out continuously, so that all the jamming can be exhausted, and the accuracy is better.
In addition, the scheme provided by the embodiment of the invention can be used for carrying out local analysis after the source video and the target video are obtained, and no additional network connection is needed; the method judges the pause frame in a frame comparison mode after video cutting, so that the required working resources are less and the efficiency is higher; according to the scheme, the picture and the video in the blocking process can be visually obtained by positioning the specific blocking first frame and the specific blocking last frame, and the picture and the video are closer to and accord with the perception experience of a user.
