Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a video processing method, a video processing device, a storage medium and a mobile terminal.
As shown in fig. 1, fig. 1 is a schematic flow chart of a video processing method provided in an embodiment of the present application, where the video processing method is applied to a mobile terminal, and the mobile terminal may be a smart phone, an iPad, and other devices having a shooting function, and a specific flow may be as follows:
s101, in the video shooting process, multiple frames of target video images are sequentially acquired.
One frame of video image refers to one image in a video, and a currently shot scene can be detected through an AI (Artificial Intelligence) scene detection function in a video shooting process to obtain a plurality of frames of target video images. Specifically, the AI scene detection function is realized based on a scene detection model, during the training process of the scene detection algorithm, the scene detection model is trained according to a plurality of preset scenes, and then the scene detection model detects the video shooting scene, wherein the preset scenes comprise characters, flowers, beaches, sky, sea, fruits, gourmet powder, buildings, snow scenes, rainy days and pets, and if the current scene is detected to be one of the preset scenes during the video shooting process, the video image in the current scene is automatically captured as the target video image.
Further, the step S101 may specifically include:
judging whether the video image meets a preset condition or not when shooting one frame of video image;
and if so, taking the video image as a target video image.
In one embodiment, every time a frame of video image is shot, whether the video image has preset image elements is detected; if the video image has preset image elements, judging whether the image elements in the video image are the same as the image elements in the newly acquired target video image, if so, determining that the video image does not meet preset conditions, and if not, determining that the video image meets the preset conditions; and if the video image does not have the preset image elements, determining that the video image does not meet the preset condition.
The latest acquired target video image is the target video image with the shortest time interval with the video image in the acquired target video images, and before the target video image is acquired for the first time, if the currently shot video image is detected to have preset image elements, the video image can be directly determined to meet the preset conditions, and the image elements in the video image do not need to be compared with the image elements in the latest acquired target video image.
Specifically, since the recognition of the above preset scene is determined according to the photographed image elements, the preset image elements may include characters, flowers, beaches, sky, sea, fruits, delicacies, buildings, snow scenes, rainy days, and pets. If the image elements in the shot video image are flowers and plants before the target video image is obtained for the first time, determining that the video image meets the preset condition, and taking the video image as the target video image; if the image elements in the shot video image are flowers and plants, determining that the video image does not meet the preset condition because the image elements are the same as the image elements (namely flowers and plants) in the newly acquired target video image; if the shot video image is an automobile, the image element does not have a preset image element, and therefore the video image is determined not to meet the preset condition.
In another embodiment, each time a frame of video image is shot, whether the acquisition time interval between the video image and the newly acquired target video image is equal to a preset time length or not is detected, and if yes, the video image is determined to meet a preset condition; if not, determining that the video image does not meet the preset condition.
For example, the preset time period is set to 1 s. If the acquisition time interval between the shot video image and the newly acquired target video image is equal to 1s, determining that the video image meets the preset condition; and if the acquisition time interval between the shot video image and the newly acquired target video image is equal to 3s, determining that the video image does not meet the preset condition.
In another embodiment, each time a frame of video image is shot, detecting whether the acquisition time interval between the video image and the newly acquired target video image is equal to a preset time length, if so, judging whether the number of the acquired target video images is less than a preset value, if so, determining that the video image meets a preset condition, and if not, determining that the video image does not meet the preset condition; and if the time length is not equal to the preset time length, determining that the video image does not meet the preset condition.
For example, the preset time period is set to 2s, and the preset value is set to 4. If the acquisition time interval between the shot video image and the newly acquired target video image is equal to 2s and the number of the acquired target video images is detected to be 3, determining that the video image meets the preset condition; if the acquisition time interval between the shot video image and the newly acquired target video image is equal to 2s and the number of the acquired target video images is detected to be 5, determining that the video image does not meet the preset condition; and if the acquisition time interval between the shot video image and the newly acquired target video image is equal to 3s, determining that the video image does not meet the preset condition.
And S102, when the video shooting is finished, synthesizing the multi-frame target video images into a dynamic image, and taking the dynamic image as a preview of the video.
In the prior art, after a video is captured, a video preview (for example, a first frame image is captured from the video) is usually saved in a gallery for a user to browse, and the user can play the video after clicking the video preview. For example, as shown in fig. 2, after the video capturing is finished, the captured video is saved in a gallery, and a still image 2004 (the first frame image in the video) is displayed as a video preview image in a gallery interface 2003, and the user can click on the still image 2004 to play the video.
When the number of the shot videos is large, if a user wants to find a certain video from the videos for browsing, the user can only roughly estimate the content of the video through the video preview image, so that the user usually needs to click a plurality of video preview images to play the plurality of videos to find the video which is desired to be browsed, which results in long time consumption and low efficiency of video query. In this embodiment, all the acquired target video images are combined into one dynamic image, the dynamic image is used as a preview of the video, and a user can directly browse the dynamic image to determine the approximate content of the video and query the video to be browsed in a short time, so that the video query time is shortened and the video query efficiency is improved.
Further, the step S102 may specifically include:
the method comprises the steps of sequencing multiple frames of target video images according to the acquisition time sequence to form an image sequence, and converting the image sequence into a graph exchange format to form a dynamic graph.
Among them, the GIF (Graphics Interchange Format) Format is a dynamic image Format, which can allow a plurality of still pictures to be played and moved rapidly and continuously according to a certain rule to form a dynamic picture, and such a dynamic picture is generally called a GIF dynamic picture. Because the image sequence is obtained by sequencing all target video images according to the acquisition time sequence, the GIF dynamic graph converted by the image sequence displays all the target video images according to the acquisition time sequence, and if a user wants to accurately find a certain video from a plurality of videos for browsing, the user can presume the rough content of the video by browsing the GIF dynamic graph, thereby improving the video query efficiency.
For example, as shown in fig. 2, a video image is captured in a video image capture interface 2001 of the mobile terminal, the current video image capture is terminated by clicking an image capture termination button 2002, the video image is stored in a gallery, and a GIF diagram 2005 formed is displayed as a preview of the video image in the gallery interface 2003, so that the user can directly browse the GIF diagram 2005 in the gallery interface 2003 to estimate the rough content of the video image.
Specifically, after the dynamic graph is used as a preview of the video, a jump link of the dynamic graph and a video file corresponding to the video is established, a touch operation on the dynamic graph is responded, the video file is jumped to according to the jump link, and the video corresponding to the video file is played.
The skip link includes a URL (Uniform Resource Locator) or a video file path, and after the video shooting is completed, a URL or a video file path is generated, and when a touch operation on the dynamic graph is detected, the skip link automatically skips to a corresponding video file according to the URL or the video file path. For example, as shown in fig. 2, when the user clicks the GIF graph 2005, jumping to the video file according to the video file path of the video file, and opening the video playing interface 2006 to play the video corresponding to the video file.
As shown in fig. 3, fig. 3 is another schematic flow chart of the video processing method according to the embodiment of the present application, and the specific flow may be as follows:
s201, in the shooting process of the video, judging whether the video image meets a preset condition or not when shooting one frame of video image; and if so, taking the video image as a target video image.
If the shot video image has preset image elements, judging whether the image elements in the video image are the same as the image elements in the newly acquired target video image, and if the image elements in the shot video image are different from the image elements in the newly acquired target video image, determining that the video image meets the preset conditions.
For example, the preset image elements include a person, flowers, grass, a beach, a sky, a sea, fruits, food, a building, a snow scene, a rainy day, and a pet, as shown in fig. 2, video shooting is performed in a video shooting interface 2001 in the mobile terminal, an image element in a currently shot video image B is flowers and grass, and an image element in a video image a (i.e., a newly acquired target video image) is a pet, and since the image element is different from the image element in the video image a, it is determined that the video image B satisfies the preset condition, and the video image B is taken as the target video image.
S202, when video shooting is finished, sequencing multiple frames of target video images according to the acquisition time sequence to form an image sequence, converting the image sequence into a graph exchange format to form a dynamic graph, and taking the dynamic graph as a preview of a video.
For example, the shooting end button 2002 is clicked to end the current video shooting, the video is saved in the gallery, and since the video image a is acquired before the video image B, an image sequence is formed in the order of the video image a and the video image B, the image sequence is converted into the GIF image 2005, the GIF image 2005 is taken as a preview of the video, and the preview is displayed on the gallery interface 2003.
S203, establishing a jump link of the dynamic graph and a video file corresponding to the video.
For example, after a video is saved, a video file path corresponding to the video is automatically generated.
And S204, responding to the touch operation of the dynamic graph, jumping to the video file according to the jump link, and playing the video corresponding to the video file.
For example, when it is detected that the user clicks the GIF graph 2005, the user automatically jumps to the corresponding video file according to the video file path, and opens the video playing interface 2006 to play the video corresponding to the video file.
In the video processing method, during the shooting process of the video, the multi-frame target video images are sequentially acquired, and when the video shooting is finished, the multi-frame target video images are synthesized into the dynamic image, and the dynamic image is used as the preview image of the video. Because the preview image is a dynamic image formed according to the shot video, when a user inquires a certain video to be browsed, the user can judge the approximate content of the video by directly browsing the dynamic image without clicking the preview image to play the video content, and the video to be browsed is inquired in a short time, so that the video inquiry time is shortened, and the video inquiry efficiency is improved.
According to the method described in the foregoing embodiment, the present embodiment will be further described from the perspective of a video processing apparatus, which may be specifically implemented as an independent entity or integrated in a mobile terminal, where the mobile terminal may be a device with a shooting function, such as a smart phone or an iPad.
