Fig. 1 is a flowchart of a first embodiment of a video conversion method according to the present application. As shown in fig. 1, the following detailed implementation is included.
In 101, a video conversion request initiated by a user for any video is obtained.
At 102, a conversion process is performed on the video, the conversion process comprising: selecting M frames of images from the video, wherein M is a positive integer, converting the M frames of images into a quadratic element cartoon style, and returning the quadratic element cartoon style to a user so that the user can select one frame of image from the M frames of images as a cover of the converted video; and converting the video into a quadratic element cartoon style, and returning the converted video to the user.
Preferably, an execution subject of the method of the present embodiment may be a server, and a user may interact with the server through a client.
Preferably, after the video conversion request of the user is obtained, preprocessing may also be performed, and the preprocessing may include the following operations.
1) And carrying out legality verification on the user according to the user information carried in the video conversion request, and if the user information passes the verification, carrying out conversion processing on the video.
What is specifically included in the user information may be determined according to actual needs, for example, a user name and a key of the user may be included. The validity of the user can be checked according to the user information, such as determining whether the user name is a registered user name, determining whether the key is a pre-negotiated key, and the like. If the verification is passed, that is, the user is determined to be a legal user, the video can be converted, and if the verification is not passed, the video conversion request can be ignored.
Through the verification operation, illegal user behaviors can be prevented, adverse effects on services caused by malignant network requests can be prevented, and the like.
2) And acquiring the recorded times of video conversion requests initiated by the user within the latest preset time, comparing the times with a preset threshold, and if the times are less than or equal to the threshold, converting the video.
The specific value of the latest preset time length can be determined according to actual needs, and the specific value of the threshold can also be determined according to actual needs.
The method comprises the steps of recording the number of times of initiating video conversion requests by the same user in the latest preset time, comparing the number of times with a threshold, carrying out conversion processing on videos if the number of times is less than or equal to the threshold, and neglecting the video conversion request if the number of times is greater than the threshold.
By the request frequency control operation, it is possible to prevent a malicious attack and reduce resource waste.
3) And if the video conversion request can be normally processed according to the service stability, converting the video.
The service stability can be judged according to the number of the processed requests, the service capability and the like, if the video conversion request can be normally processed according to the service stability, the video can be converted, and if not, the video conversion request can be ignored.
In addition, when the service is abnormal, the standby service can be started to ensure the user experience, and meanwhile, relevant warning operators can be informed to search problems in time. If necessary, the standby service can be started when the service is not abnormal, so that resource expansion and the like are realized.
Through the operation, the video conversion request can be processed normally, and the user experience is improved.
In practical applications, only one operation of 1), 2), and 3) may be performed, any two operations may be performed, and the three operations may be performed. Assuming that both operations 1) and 2) are performed, only when the check is passed and the number of times is less than or equal to the threshold value, the subsequent processing, that is, the conversion processing of the video is continued.
Before the video is subjected to the conversion processing, a video conversion task for the video can also be preferably generated and put into the first buffer area. And according to a preset scheduling strategy, when the fetching condition is met every time, P video conversion tasks are fetched from the first cache region, wherein P is a positive integer, and the conversion processing is carried out on the video corresponding to the fetched video conversion tasks.
For example, a certain number of video conversion tasks may be fetched from the first buffer area at regular intervals according to the conversion capability and the like according to the first-in first-out principle, and the videos corresponding to the fetched video conversion tasks may be converted. The number of video conversion tasks to be fetched at a time, etc. may be determined according to actual circumstances.
Through caching and scheduling, sufficient conversion time can be reserved for each video, and the conversion success rate is improved.
In addition, subsequently, the converted M-frame image and the converted video may be placed in the second cache region as a conversion result, and when the query request of the user is obtained, the conversion result may be returned to the user.
If a request for canceling the conversion of the video by the user is received, the process may be terminated, that is, the process for the video may be terminated. For example, if a video conversion task corresponding to a video is not yet taken out from the first cache region when a request for canceling the conversion of the video by the user is received, the video conversion task corresponding to the video may be deleted from the first cache region, so that the video is not subjected to subsequent processing.
When the video is converted, the animation processing of the image and the animation processing of the video can be performed respectively. The animation processing of the image may be selecting M frames of images from the video, where M is a positive integer, respectively converting the M frames of images into a quadratic element cartoon style, and returning the quadratic element cartoon style to the user, so that the user can select one frame of image from the M frames of images as a cover of the converted video.
The specific value of M can be determined according to actual needs, and is usually greater than one, such as 10. How to select the M frames of images may also be determined according to actual needs, for example, the M frames of images may be randomly selected, and for example, the M frames of images with clear human images, easy recognition and front faces may be selected.
The M-frame images can be respectively converted into a two-dimensional cartoon style by calling an Artificial Intelligence (AI) intelligent vision conversion algorithm, which is specifically realized in the prior art. Converting to a two-dimensional cartoon style may refer to converting characters therein to two-dimensional cartoon characters, etc.
The converted M-frame image may be placed in the second cache area as a conversion result, and when the query request of the user is obtained, returned to the user. The user can select a favorite frame image from the converted M frame images as the cover of the converted video according to personal preferences.
When the video is converted into the quadratic element cartoon style, the video can be firstly cut into N video segments, wherein N is a positive integer larger than one, then the N video segments can be concurrently converted into the quadratic element cartoon style respectively, and then the converted video segments can be spliced, so that the converted video is obtained.
The specific value of N may be determined according to actual needs, for example, if the total duration of the video is 20 seconds, the video may be divided into 4 video segments, and the duration of each video segment is 5 seconds. And aiming at each video clip, an AI intelligent visual conversion algorithm can be respectively called to convert the video clip into a quadratic element cartoon style. A video clip is composed of a plurality of frames of images and is therefore essentially the same as the transition of images.
By segmenting the video segments and concurrently converting each video segment, the video conversion duration can be shortened, the conversion speed is increased, the waiting time of a user is reduced, and the like.
And further, the convertible video is used as a conversion result and is put into a second cache region, and when the query request of the user is obtained, the conversion result is returned to the user.
Preferably, the query time interval of the user can be determined and returned to the user. Such as a reasonable query time interval, which can be determined based on the conversion capability and the number of requests to be processed. Thus, the user can send out the query request periodically according to the query time interval.
Correspondingly, when the query request periodically sent based on the query time interval is acquired, if the conversion result of the video cached in the second cache region is determined, that is, the video is determined to be converted, the conversion result can be returned to the user, and the conversion result includes the converted M-frame image, the converted video and the like.
When the query request periodically transmitted based on the query time interval is acquired, if it is determined that the video is being subjected to conversion processing, processing progress information may be returned to the user, and the processing progress may be determined in an existing manner, such as 60% processed.
And/or when the query request periodically sent based on the query time interval is acquired, if the video conversion is determined to fail, the conversion failure information can be returned to the user, and the user can be reminded to retry and the like. Failure of video conversion may be caused by various reasons, such as abnormal service or unreadable data contained in the video.
By determining the query time interval, blind and frequent queries by the user can be avoided, thereby reducing unnecessary resource consumption and the like. In addition, based on the query request, the user can know the processing situation of the video and the like in time.
