Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Fig. 1 is a schematic view of an application scenario of video processing. The shooting equipment is used for shooting an object to be shot to obtain original video information. And then, sending the original video information to a video processing platform, and performing processing (for example, processing such as clipping, adding subtitles, rendering images, and the like) by the video processing platform, where the video processing platform may be a server in a cloud, and is not limited herein. And sending the processed video to a playing device (such as a television, a mobile phone, a cinema playing device, and the like), and playing the video after the playing device receives the processed video. And further, the processed video enables the audience to have better film watching experience.
At present, when the video is post-processed, post-personnel are generally required to browse the video on a video processing platform according to the time sequence of the video and process the video according to human experience. Because the video post-processing has higher processing capacity requirement on the video processing platform and is limited by equipment, the post-processing personnel are less. However, as the duration of the video increases, the workload of the post-processing personnel increases, resulting in a decrease in the video post-processing speed.
The following describes the technical solution of the present application and how to solve the above technical problems in detail by specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a video processing method according to an embodiment of the present disclosure. As shown in fig. 2, the method includes:
s101, obtaining target video information to be processed;
s102, dividing the target video information to obtain a plurality of first video segments.
Exemplarily, an application scenario of the video processing method provided by the embodiment of the present application is as shown in fig. 3. Fig. 3 is a schematic view of an application scenario of video processing provided in the present application, where the application scenario includes a client 1, a client 2, a client 3, and a video processing platform 4. The video processing platform may be a remote server. The client may be an application installed on a device and the application is not as demanding as the processing power of the device.
After the video processing platform receives the target video information, the video processing platform splits the received target video information into a plurality of first video segments. In a possible implementation manner, the target video information may be distributed evenly or randomly according to the time length directly according to the number of clients connected to the video processing platform.
S103, respectively issuing the plurality of first video segments and the annotation file to each client, wherein the annotation file comprises a plurality of preset video characteristic labels.
Illustratively, after obtaining a plurality of first video segments, a preset annotation file and the first video segments are sent to each client. For example, the obtained first video segments are: a first video segment 1, a first video segment 2 and a first video segment 3. Then, the first video segment 1 is sent to the client 1, the first video segment 2 is sent to the client 2, and the first video segment 3 is sent to the client 3.
In addition, when the first video segment is issued to each client, an annotation file is sent to each client, wherein the annotation file comprises a plurality of preset video characteristic labels. For example, the predetermined plurality of video characteristic tags may include a plurality of the following tags: contrast label, brightness label, motion label, human face label. It should be noted that the video feature tags in the present application include, but are not limited to, the tags illustrated above. The face label can be used to label key face details in the video segment that need to be emphasized, and the resolution of the video segment needs to be improved, for example, when details such as facial expressions of characters such as a main character in a movie need to be highlighted, a face feature label can be added to the details. And, when it is known in advance that the acquired target video information is a video for describing the growth of the animal, wherein no face appears, the preset video characteristic tags may include: a contrast label, a brightness label, and a motion label.
S104, receiving annotation information sets corresponding to a plurality of first video segments returned by the clients, wherein the annotation information set corresponding to the first video segment comprises at least one video characteristic label in a plurality of video characteristic labels.
Illustratively, after the client receives a plurality of first video segments, the user selects a video characteristic tag from the received annotation file to generate an annotation information set corresponding to the first video segment, and uploads the annotation information set to the video processing platform. That is, the user adds the video property tag to the video segment at the client, which indicates that the video segment corresponding to the user needs to perform one or more types of video processing, for example, when the contrast tag is selected for the first video segment, it indicates that the contrast of the first video segment needs to be adjusted. And then, sending the generated annotation information set to a video processing platform.
Optionally, in order to associate a first video segment with a set of annotation information, start time information, end time information, and a total number of frames corresponding to the first video segment can be set in the set of annotation information.
And S105, processing the first video segments according to the annotation information set corresponding to each first video segment to obtain the processed video information.
For example, after receiving the annotation information set, the video processing platform processes each first video segment according to the video property tag included in the annotation information set corresponding to the first video segment. Specifically, when the video processing platform processes the video, each time a labeling information set is received, a first video segment corresponding to the labeling information set is searched in the platform and processed, and after all the first video segments are processed, the processed video segments are combined according to the sequence of the original time of the video to obtain the processed video.
It should be noted that, when the video processing platform and the client may perform communication interaction (for example, the client uploads a label information set to the video processing platform and the video processing platform issues a video segment and a label file to the client), the communication modes of the video processing platform and the client may be various, including but not limited to a fourth generation mobile information system (4 th generation mobile communication technology, abbreviated as 4G), a fifth generation mobile communication technology (5 th generation mobile networks, abbreviated as 5G), and the like.
In this embodiment, when performing post-processing on a video, the processing capability of the device required by the required processing program is high, so the video processing platform may be a device with high processing capability, such as a remote server. The target video information is divided by the video processing platform and then is sent to the client-side equipment with weak processing capability, so that the label information sets are generated by adding labels to the video segments at the plurality of client-sides and then are uploaded to the video processing platform, and then the video processing platform can process the first video segments according to the label sets corresponding to the first video segments. By the method, multiple persons can simultaneously process each video segment in the same video, the video processing speed is improved, and the method has low requirement on the processing capacity of equipment and is easy to realize.
In practical applications, when the target video information is divided (i.e. when step S102 is executed), the division can be realized by the steps shown in fig. 4. Fig. 4 is a schematic flowchart of a method for dividing video information according to an embodiment of the present application, as shown in fig. 4, including the following steps:
s201, dividing the target video information according to the shot to obtain a plurality of second video segments.
For example, when dividing the target video information, the target video information may be divided according to the existing shot detection technology to obtain a plurality of second video segments, where each second video segment corresponds to a shot.
For example, the conventional shot detection technology usually determines according to a difference between contrast and a luminance motion vector between adjacent frame images in the target video, and if the difference is large, the adjacent frame images are in two different shots.
S202, distributing each second video segment to the first video segments to obtain a plurality of first video segments, wherein each first video segment comprises at least one second video segment.
In one example, step S202 may be performed by:
the method comprises the steps of firstly, determining the number of a plurality of first video segments according to the number of current online clients;
secondly, detecting the duration of each second video segment;
and thirdly, distributing each second video segment to the first video segment according to the number of the first video segments and the time length of each second video segment to obtain a plurality of first video segments, wherein the time lengths of the first video segments are equal.
Illustratively, after obtaining the plurality of second video segments, the video processing platform detects the number of currently online clients, and takes the number of currently online clients as the number of first video segments. In another case, the video processing platform can also determine the number of the first video segments according to the number of the clients specified by the user.
And then, obtaining a plurality of first video segments with the same duration according to the detection of the duration of each second video segment, the number of the first video segments and the duration of each second video segment, wherein the duration of the first video segments is the sum of the durations of the second video segments included in the first video segments.
In another case, the duration of the first video segment can be different. For example, the time length of each of the divided first video segments is within a preset time length range. For example, by setting the total duration of the target video information to be 100min and the number of the clients to be 5, it is determined that the average duration of each client is 20min, and the preset duration range may be 18min to 22min, so that when a plurality of first video segments are obtained through the duration of the second video segment and the number of the first video segments, the integrity of the second video segment is ensured, that is, each second video segment only corresponds to one first video segment, and the obtained durations of the plurality of first video segments are all 18min to 22min, so that the post-processing is more accurate.
In one example, to allocate each second video segment to a first video segment to obtain a plurality of first video segments (i.e., when performing step S202), the following steps can be further performed:
step one, identifying each second video segment, and determining the content type of each second video segment;
and secondly, distributing each second video section to the first video section according to the content type of each second video section to obtain a plurality of first video sections, wherein the content type of the second video section corresponding to each first video section is the same.
Illustratively, after obtaining the plurality of second video segments, in order to distribute and generate the plurality of first video segments, the following method can be used. Firstly, the video processing platform identifies the frame image in each second video segment, and then determines the content type in the second video segment. For example, the content category of the second video segment 1 includes sky, mountain, grassland, tree. The content category of the second video segment 2 includes: sky, river, grass. The content category of the second video segment 3 includes: sky, building, pedestrian. The content category of the second video segment 4 includes: sky, river, grass. In the second video segment, the second video segment 2 and the second video segment 4 include the same internal same type, so that the second video segment 1 and the second video segment 3 can be respectively delivered to the first video segment 1 and the first video terminal 2, the second video segment 2 and the second video segment 4 are distributed to the same first video segment 3, namely delivered to the same client, and the characteristics of the tag are selected by the same user, so that the post-processing difference of the same content is not large due to human subjective factors during processing.
In addition, in another embodiment, since the similarity of the content types in the second video segments 1 and 2 is high, a similarity threshold may also be set, and a video with a video similarity between the second video segments higher than the similarity threshold is allocated to the same first video segment. That is, the similarity between the second video segment 1, the second video segment 2 and the second video segment 4 is higher, and the second video segment 2 can be assigned to the first video segment 1, and the similarity between the second video segment 2 and the rest of the second video segments is lower, and the second video segment 2 can be assigned to the first video segment 2.
Alternatively, in this example, when the second video segments are allocated according to the content category, the allocation may also be performed in combination with the time length of each second video segment, that is, the method of this example is combined with the method of the previous example. Subsequently, when the client determines the annotation information set corresponding to the first video segment, the annotation information sets corresponding to a plurality of second video segments included in the first video segment can be included therein. That is, the annotation information sets of the second video segments in the first video segment constitute the annotation information set of the first video segment. In another possible case, the annotation information set corresponding to the first video segment is composed of annotation information sets corresponding to the frames of images in the first video segment.
In this embodiment, when dividing the video segments, the target video information may be divided into a plurality of second video segments according to the shots, and then the plurality of second video segments are distributed to the plurality of first video segments to obtain a plurality of first video segments. Specifically, the allocation can be performed according to the time length of each second video segment and the number of the first video segments, so that the time length of each first video segment is equal, the workload of each client is the same, and the video processing speed is increased. In addition, the first video segments can be distributed according to the content sets of the second video segments, so that the content types of the second video segments in each first video end are the same or the similarity is higher, and further, during post-processing, the same content is not affected by human factors to cause larger processing difference, the processing speed is increased, and the processing accuracy is improved.
In practical application, when the video processing platform receives the annotation information set sent by the client and processes the plurality of first video segments, the following steps may be implemented (that is, step S105 includes the following steps), as shown in fig. 5, fig. 5 is a schematic flow diagram of a video information processing method provided by the present application:
s1051, determining a video processing program corresponding to a video characteristic label in an annotation information set according to the annotation information set corresponding to each first video segment;
and S1052, calling a video processing program corresponding to the video characteristic label in the annotation information set, and processing the first video segment.
Illustratively, after the video processing platform acquires each annotation information set, for each first video segment, a video characteristic tag is searched in a tag information set corresponding to the first video segment, and then a video characteristic processing program corresponding to the video characteristic tag in the annotation information set is determined. For example, if a video characteristic set corresponding to a certain first video segment includes a brightness characteristic tag, a brightness adjustment processing program corresponding to the brightness characteristic tag is determined according to the brightness characteristic tag, where a correspondence between the video characteristic tag and the video processing program may be stored in the video processing platform in advance.
And then, after determining a video processing program corresponding to the first video segment, the video processing platform calls the video processing program to process the first video segment.
