Fig. 1 is a diagram illustrating an implementation environment involved in a method for detecting a multimedia asset according to an exemplary embodiment, the environment including: a terminal 10 and a server 20.
The terminal 10 may be a smart phone, a tablet computer, a notebook computer, or the like, and the product type of the terminal 10 is not specifically limited in the embodiments of the present disclosure.
The server 20 has a storage capability for storing multimedia resources and a video frame set obtained by performing frame extraction on a target multimedia resource, and the server 20 also has a computing capability for performing frame extraction on the multimedia resources.
The terminal 10 and the server 20 may communicate with each other through a wired network or a wireless network.
Fig. 2 is a flowchart illustrating a method for detecting a multimedia resource according to an exemplary embodiment, taking a server as an example to execute the embodiment of the present disclosure, as shown in fig. 2, the method for detecting a multimedia resource provided by the embodiment of the present disclosure includes the following steps:
In this step, the server may obtain the target multimedia resource that needs to be detected.
For example, a user may obtain or release multimedia resources through an existing video playing platform, so that a large number of multimedia resources are included in the video playing platform, and in order to ensure the quality of the multimedia resources in the platform, a detection person of the video playing platform needs to detect the multimedia resources, and at this time, the detection person may obtain a target multimedia resource to be detected from the large number of multimedia resources in the video playing platform by using a server.
In this step, after acquiring the target multimedia resource, in a case that a frame extraction request for the target multimedia resource is received, the server may, in response to the frame extraction request, first determine a target resource type of the target multimedia resource, and determine a target frame extraction policy corresponding to the target resource type, so that the target frame extraction policy for the target multimedia resource may be determined for target multimedia resources of different resource types, so that the frame extraction policy for the target multimedia resource is applicable to the target multimedia resource.
It should be noted that the frame extracting request may be a frame extracting request sent by a user through a terminal, or may be a frame extracting request generated by a server when a certain trigger condition is met, for example, when the uploading process of the target multimedia resource is completed, the frame extracting request for the target multimedia resource may be generated, so as to respond to the frame extracting request, determine a target frame extracting policy corresponding to the target multimedia resource, and complete the frame extracting process of the target multimedia resource.
In the embodiment of the present invention, the target resource types of the target multimedia resource may include a picture video type, a short video type, and a long video type.
The display content of the target multimedia resource of the picture video type includes at least one first picture, for example, a multimedia resource is manufactured by various video manufacturing software according to a specific rule by using a plurality of original pictures, and a video frame in the multimedia resource is generated by the plurality of original pictures through operations such as dynamic effect, post-editing and the like.
In addition, the duration of the target multimedia resource of the short video type is less than or equal to a first preset time, and the duration of the target multimedia resource of the long video type is greater than or equal to a second preset time, that is, the target multimedia resource with shorter duration is determined as the short video type, and the target multimedia resource with longer duration is determined as the long video type.
The first preset time may be the same as the second preset time, or may be different from the second preset time, for example, the first preset time is 10 seconds, the second preset time is 30 minutes, the multimedia resource with the duration less than or equal to 10 seconds is a short video type, and the multimedia resource with the duration greater than or equal to 30 minutes is a long video type.
Further, a target frame extraction strategy corresponding to the target resource type can be determined according to the target resource type of the target multimedia resource.
Specifically, the target frame extraction strategy applicable to the type of target multimedia resource can be determined according to the characteristics of the target resource type of the target multimedia resource.
For example, if the target multimedia resource is of a picture video type, it indicates that video frames included in the target multimedia resource are all composed of original pictures for generating the target multimedia resource, and therefore, a target frame extraction strategy corresponding to the picture video type can be used for extracting the original pictures for generating the target multimedia resource.
If the target multimedia resource is of a short video type, the duration of the target multimedia resource is short, so that the video frames with the number of the target frame extraction number can be extracted from the target multimedia resource directly according to the fixed target frame extraction number.
If the target multimedia resource is of a long video type, it indicates that the duration of the target multimedia resource is long, and if a detection person directly extracts video frames with the number of target frames from the target multimedia resource according to the fixed number of target frames, the extraction time interval from the target multimedia resource may be long due to the fact that the number of target frames is too small, and the number of video frames is small, so that the extracted video frames cannot well and uniformly cover the content of the target multimedia resource, and the detection person cannot easily detect and evaluate the content of the multimedia resource according to the frame extraction result. Therefore, the frame can be extracted from the target multimedia resource according to the frame extraction time interval directly according to the fixed frame extraction time interval, so that the video frames which are moderate in quantity and can better and uniformly cover the content of the target multimedia resource are obtained.
In this step, the server may perform frame extraction on the target multimedia resource according to the determined target frame extraction policy, so as to obtain a video frame set including at least one video frame according to a picture extracted from the target multimedia resource, where the video frame set is applied to a scene in which the target multimedia resource is detected and includes at least one video frame extracted from the target multimedia resource, so that the obtained video frame set may be used by a detection person to detect and evaluate the content of the target multimedia resource according to the video frame set.
In the embodiment of the invention, frames can be extracted from the target multimedia resource by adopting a media resource frame extraction frame (ffmepg) which all depend on an open source according to a target frame extraction strategy, wherein the frames are frequency frames. Wherein ffmepg is a set of open source computer programs which can be used for recording and converting digital audio and video and can convert the digital audio and video into streams, and can provide a complete solution for recording, converting and streaming audio and video.
To sum up, a method for detecting multimedia resources provided by the embodiment of the present application includes: acquiring a target multimedia resource; in response to receiving a frame extracting request aiming at a target multimedia resource, determining a target resource type of the target multimedia resource, and determining a target frame extracting strategy corresponding to the target resource type; according to a target frame extraction strategy, extracting frames from a target multimedia resource to obtain a video frame set comprising at least one video frame, wherein the video frame set is applied to a scene for detecting the target multimedia resource and comprises at least one video frame extracted from the target multimedia resource, in the embodiment of the application, the target frame extraction strategy for the target multimedia resource can be determined according to the target resource type of the target multimedia resource, so that the frame extraction operation is performed from the target multimedia resource with complicated content by using the target frame extraction strategy to obtain the video frame set comprising at least one video frame, the video frame set is applied to the scene for detecting the target multimedia resource, and after the video frame set is sent to a terminal and displayed, as the video frame set comprises partial video frames extracted from the target multimedia resource, the detection personnel can check the video frame set through the terminal and detect and monitor the target multimedia resource according to the video frame set, so that the time for detecting the target multimedia resource is shortened, and the detection efficiency is improved.
Fig. 3 is a flow chart illustrating steps of another method for detecting multimedia assets according to an exemplary embodiment, as shown in fig. 3, including the steps of:
This step can refer to step 101, and is not described herein.
This step can be referred to as step 102, and is not described herein.
In this step, if the target resource type is the picture video type, it may be determined that the target frame extraction policy is a first target frame extraction policy.
In this step, when the target resource type is the picture video type, determining that a target frame extraction strategy is a first target frame extraction strategy, and performing frame extraction on the target multimedia resource according to the first target frame extraction strategy.
Specifically, the first target frame extraction policy may first determine at least one first picture included in the display content of the target multimedia resource of the picture video type, acquire the first picture, and generate a video frame set including the first picture according to the first picture, where the video frame set is applied to a scene for detecting the target multimedia resource.
In this step, if the target resource type is the short video type, it may be determined that the target frame extraction policy is a second target frame extraction policy.
In this step, when the target resource type is the short video type, determining that the target frame extraction strategy is a second target frame extraction strategy, and performing frame extraction on the target multimedia resource according to the second target frame extraction strategy.
Specifically, the second target frame extraction policy may determine a target frame extraction number of a target multimedia resource of a short video type, further extract a second picture of which the number is the target frame extraction number from the target multimedia resource, and generate a video frame set including the second picture according to the second picture, where the video frame set is applied to a scene for detecting the target multimedia resource.
The target frame number may be a numerical value input by a detection person, a default fixed numerical value, or a numerical value automatically generated according to the duration of the target multimedia resource.
Optionally, the step of performing frame extraction on the target multimedia resource according to the target frame extraction policy to obtain a video frame set including at least one video frame may specifically include:
substep 2061, determining a first target frame extracting time interval according to the duration of the target multimedia resource and the target frame extracting quantity.
In this step, after determining the target number of frames of the target multimedia resource, a first target frame-extracting time interval may be determined according to the duration of the multimedia resource and the target number of frames.
Specifically, a ratio of the duration of the target multimedia resource to the target frame extraction number may be determined, and the ratio is used as a time interval for performing frame extraction from the target multimedia resource, that is, a first target frame extraction time interval.
For example, if the duration of the target multimedia resource is 18 seconds, the target frame number is 9 frames in a fixed number determined by the detection personnel, the ratio of the duration of the target multimedia resource to the target frame number is 2, the first target frame extraction time interval is 2 seconds, that is, 9 second pictures can be extracted from the target multimedia resource with the duration of 18 seconds at a time interval of 2 seconds.
Substep 2062, performing frame extraction from the target multimedia resource at each interval of the first target frame extraction time interval, and obtaining the second pictures with the number of the target frame extraction.
In this step, after the first target frame extraction time interval is determined, frame extraction may be performed at intervals of the first target frame extraction time interval from the target multimedia resource to obtain the second pictures with the number equal to the target frame extraction number, and a video frame set including the second pictures is generated according to the second pictures.
And step 207, when the target resource type is the long video type, determining that the target frame-extracting strategy is a third target frame-extracting strategy.
In this step, if the target resource type is the long video type, it may be determined that the target frame extraction policy is a third target frame extraction policy.
In this step, a second target frame extraction time interval of the target multimedia resource may be determined, a third picture may be extracted from the target multimedia resource at each second target frame extraction time interval, and a video frame set including the third picture may be generated according to the third picture, where the video frame set is applied to a scene for detecting the target multimedia resource.
The second target frame-drawing time interval may be a time value input by a detection person, a default fixed time value, or a time value automatically generated according to the duration of the target multimedia resource.
For example, if the duration of the target multimedia resource is 30 minutes, and the second target frame extraction time interval is a fixed time value 30 seconds determined by the detection person, it indicates that the detection person wants to extract one frame of picture from the target multimedia resource every 30 seconds as a third picture, and the target multimedia resource with the duration of 30 minutes can extract 60 frames of third pictures in total.
And 209, performing dimension reduction processing on each video frame in the video frame set to generate low-rank matrix data.
In this step, after performing frame extraction on the target multimedia resource, dimension reduction processing may be performed on each video frame in the obtained video frame set, so as to generate low-rank matrix data.
Specifically, in actual signal or image acquisition and processing, the higher the dimensionality of the data is, the greater the limitation is brought to the acquisition and processing of the data, for example, when a three-dimensional or four-dimensional (three spatial dimensions plus one spectral dimension or one time dimension) signal is acquired, the processing and acquisition of the data are often difficult, however, as the data dimensionality increases, there are often more correlations and redundancies between these high-dimensional data, and for a frame of picture, the correlation between pixels shows that coefficients of the picture in a certain transform domain are sparsely distributed, so that the sparsity and redundancy existing between the high-dimensional data can be reasonably and fully utilized, and through dimension reduction processing, the data can be efficiently acquired, represented and reconstructed, so that it can occupy a smaller storage space, and can be acquired and processed more efficiently.
In the embodiment of the invention, the dimension reduction processing can be carried out on each video frame contained in the obtained video frame set, so that the video frames are converted into low-rank matrix data which has lower relevance and redundancy and occupies smaller storage space by using vector data with more relevance and redundancy, and thus, the larger pressure of the video frame set obtained after the frame extraction of the target multimedia resource on the storage space is reduced.

And step 211, sending the video frame set to the terminal for displaying.
After the video frame set is obtained, the server can send the video frame set to a terminal through a wired network or a wireless network so that the terminal can display the video frame set.
In this step, in order for the inspector to acquire the set of video frames extracted from the target multimedia asset through the terminal, and detecting and evaluating the content of the target multimedia resource according to the video frame set, after receiving the video frame set, the video frame set can be displayed in a display screen of the terminal, and further, at least one video frame included in the video frame set can be displayed in a playing interface of the target multimedia resource in the terminal, so that the detecting person can conveniently display the video frame set on the display screen of the terminal through the at least one video frame included in the video frame set, after determining that the illegal content may appear in one of the video frames, the part of the target multimedia resource related to the illegal video frame may be directly played in the playing interface to further confirm whether the illegal content exists in the target multimedia resource.
Optionally, the video frame set further includes relative time information of each video frame located in the target multimedia resource, and step 211 specifically includes:
sub-step 2111, sending the video frame set to the terminal, so that the terminal can display each video frame contained in the video frame set and the relative time information corresponding to each video frame.
After the video frame set is obtained, the server can send the video frame set to a terminal through a wired network or a wireless network so that the terminal can display the video frame set.
In this step, in order to facilitate the detection personnel to acquire a video frame set extracted from the target multimedia resource through the terminal and detect and evaluate the content of the target multimedia resource according to the video frame set, the terminal may display the video frame set on a display screen of the terminal after receiving the video frame set, further, may display at least one video frame included in the video frame set and the relative time information of the video frame located in the target multimedia resource in a playing interface of the target multimedia resource in the terminal, so that the detection personnel may locate the position of the video frame located in the target multimedia resource through the at least one video frame included in the video frame set directly according to the relative time information corresponding to the video frame after determining that the content of violation may occur in one of the video frames, and playing a part related to the violation video frame in the target multimedia resource in the playing interface so as to further confirm whether violation content exists in the target multimedia resource.
