Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

FIG. 1 is a diagram of an exemplary video processing system. Referring to fig. 1, the video processing method is applied to a terminal 100, an operating system 110 runs on the terminal 100, and an application 120 implementing the video processing method runs on the operating system 110. The terminal 100 may be a desktop terminal or a mobile terminal, and the mobile terminal may be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The operating system 110 may be used to support the running of the application program 120, and the operating system 110 provides a system call interface for the application program 120 and allocates resources required for the running of the application program, so that the application program 120 implements a corresponding function through a call. The application program 120 may implement a video processing method based on a system call interface provided by the operating system 110. Application 120 may provide a visualized user interface and interact with the user through the user interface.

In one embodiment, as shown in FIG. 2, a video processing method is provided. The present embodiment is mainly illustrated by applying the method to the terminal 100 in fig. 1. Referring to fig. 2, the video processing method specifically includes the following steps:

s202, acquiring the video clip.

The video clip is a video frame set formed by arranging a plurality of video frames according to a playing sequence. The video clip can be a video section shot by the terminal through the camera immediately, a video section stored in the system album, or a video section cut from a video file stored in the system album. A video frame is the smallest unit image that makes up a video clip. One frame of video corresponds to one still image.

Specifically, the terminal detects a confirmation instruction for generating a dynamic image, and when the confirmation instruction is detected, the terminal locally queries and acquires a corresponding video segment according to the detected confirmation instruction. The locally stored video clip may be a video clip stored in the system album, such as a video clip directly captured by a camera and stored in the system album, or a video clip captured from a captured video file and stored in the system album. The locally stored video clips may also be video clips stored in a temporary storage space allocated by the system, and the temporary storage space is used for storing data generated in the process of processing the video to generate a corresponding dynamic image.

In one embodiment, the terminal can detect a source video file selection operation to determine a source video file to be edited, and display video frames of the source video file in a designated area according to a playing time sequence; the terminal can detect the editing operation and adjust the video frame in the designated area according to the editing operation; and when the terminal detects the confirmation instruction, generating a video clip, wherein the video clip comprises the video frames in the designated area when the confirmation instruction is detected.

In one embodiment, when the terminal generates the video clip, the video frames in the designated area can be synthesized into the video clip, and the video clip can also be extracted from the video file according to the time stamps of the first and last video frames in the designated area.

S204, adding first metadata in the video clip; the first metadata is used to form the video segments into a dynamic portion of the dynamic image when the dynamic image is generated.

Here, the metadata (metadata) is special data for describing data, and is mainly information for describing data attributes. The first metadata is used to identify that the video clip is a video clip that can be a dynamic portion of a dynamic image. The first metadata may include data consisting of a Key-Value pair (Key-Value), wherein the Key (Key) is a content identification and the Value (Value) may be randomly generated by the system. The value may be a UUID (universal Unique Identifier). And different video clips have different values of the correspondingly added content identifiers.

The dynamic image is an image that can be played dynamically. The dynamic image specifically includes a dynamic portion and a cover, and there are two display states, a static display state and a dynamic display state. When the dynamic image is in a still display state, only the cover is displayed; when the dynamic image is in a dynamic display state, the dynamic part is played according to the playing time sequence. The static display state and the dynamic display state can be switched by a specified operation.

The dynamic portion of the dynamic image may be a video clip consisting of successive video frames. The dynamic image may be Live Photo (which is a Live image capable of being played dynamically), where the Live Photo is composed of a static image and a video clip with a specific format, the static image is displayed when the Live Photo is still, and the video clip in the dynamic image can be played frame by pressing the displayed static image.

Specifically, when the terminal acquires a video clip, first metadata meeting a first preset condition is correspondingly generated, the generated first metadata is added to the corresponding video clip, so that the corresponding video clip is identified according to the value of the content identifier in the first metadata when the dynamic image is generated, and the identified video clip forms a dynamic part of the corresponding dynamic image.

The first preset condition is a preset condition for specifying the data structure of the first metadata, for example, the first metadata is specified as data constituted by key value pairs. The first preset condition may also be used to specify that the content identifiers in the first metadata and the second metadata respectively generated corresponding to the same confirmation instruction have the same value, for example, the same UUID. And the terminal checks whether the video clip added with the first metadata is matched with the static image of the second metadata according to the same value of the content identification in the first metadata and the second metadata.

In one embodiment, the terminal may dynamically generate the corresponding first metadata when the confirmation instruction is detected, and add the generated first metadata to the corresponding video clip during or after the video clip is acquired. The terminal can also generate corresponding first metadata after acquiring the video clip according to the confirmation instruction. The position where the first metadata is added to the video segment is not particularly limited, and may be added to the start frame of the video segment, for example. The first metadata added to the video clip is used to identify that the entire video clip is available as a dynamic portion of the dynamic image.

In one embodiment, the first metadata may also include timing metadata. The timing metadata may include a static display flag and a static display time. And the static display mark indicates that when the terminal detects a playing instruction of the dynamic image, the static image is kept displayed for a period of time and then the dynamic part is played. The static display time is a time length for keeping displaying the static image when the play instruction is detected. The static image may be a cover of the dynamic image or a video frame in the dynamic part.

In one embodiment, the timing metadata may further include a timestamp corresponding to a video frame in the dynamic portion. When the terminal detects a playing instruction, the terminal can extract the video frame corresponding to the time stamp from the dynamic part of the video clip as a static image, and when the static image is displayed for reaching the static display time, the terminal starts to play the dynamic part.

S206, acquiring a static image.

The still image is an image in which a display screen is kept unchanged when displayed. The still image may be an image in a video file that corresponds to a single video frame. The still image may be any video frame in a video clip, may be any video frame in a video file corresponding to the video clip, or may be an image taken separately.

Specifically, when the terminal detects a confirmation instruction for generating a dynamic image, the terminal locally queries and acquires a corresponding static image according to the detected confirmation instruction, wherein the acquired static image is used for forming a cover of the dynamic image when the dynamic image is generated. The captured still image may be any video frame captured from a video clip or a video file corresponding to a video clip. The static image may specifically be a video frame which is obtained from a video clip or a video file in advance and stored in a system album or a temporary storage space allocated by the system. The still image may also be a video frame determined by the terminal in a video clip or video file based on a locally stored timestamp.

S208, adding second metadata in the static image; the second metadata is used to form the still image into a cover of the moving image when the moving image is generated.

Wherein the second metadata is for identifying that the still image is a still image that can be a cover of the moving image. The second metadata is data comprising pairs of keys, where a key is a content identifier, say 17, and the values may be randomly generated by the system. The value may be a UUID. Different static images correspond to different added content identifications. The dynamic part of the dynamic image and the cover page contain the same value of the content id.

When the dynamic image is generated, whether the value of the content identifier contained in the first metadata added to the video clip is the same as the value of the content identifier contained in the second metadata added to the static image is used as a basis for verifying whether the video clip used for forming the dynamic part of the dynamic image matches the static image used for forming the cover sheet of the dynamic image. If the video clips are the same as the static images, the corresponding video clips are matched with the static images, and the terminal generates corresponding dynamic images according to the matched video clips and the static images. The cover of the moving image is a still image displayed when the moving image is in a still display state.

Specifically, when the terminal acquires the static image, the terminal correspondingly generates second metadata meeting a second preset condition, and adds the generated second metadata to the corresponding static image, so that the corresponding static image is identified according to the value of the content identifier in the second metadata when the dynamic image is generated, and the identified static image forms the cover of the corresponding dynamic image. The second preset condition is preset data for specifying the data structure and the partial data of the second metadata, for example, specifying the data structure of the second metadata as a key value pair, or specifying a key in the key value pair as 17.

In one embodiment, the terminal may dynamically generate the corresponding second metadata when the confirmation instruction is detected, and add the generated second metadata to the corresponding still image when or after the still image is acquired. The terminal can also generate corresponding second metadata after acquiring the static image according to the confirmation instruction.

In one embodiment, the order of acquiring the video clip and the still image when the terminal detects the confirmation instruction is not particularly limited. The terminal may perform the step of acquiring the still image after acquiring the video clip and adding the corresponding first metadata to the acquired video clip. The terminal may also perform the step of acquiring the video clip after acquiring the still image and adding the second metadata to the acquired still image. The terminal may also perform the steps of acquiring the video clip and the still image in parallel.

S210, generating a dynamic image according to the video clip added with the first metadata and the static image added with the second metadata; the dynamic image includes a dynamic portion and a cover.

Specifically, after respectively adding corresponding first metadata and second metadata to a video clip and a static image respectively acquired according to a confirmation instruction, the terminal takes the video clip added with the first metadata as a dynamic part of a dynamic image and takes the static image added with the second metadata as a cover of the dynamic image to generate a corresponding dynamic image.

In one embodiment, after the terminal adds the corresponding first metadata and second metadata to the obtained video clip and the still image, the metadata are temporarily stored locally. When the terminal generates the dynamic image, the video clip added with the first metadata and the static image added with the second metadata are respectively acquired from the local, and the corresponding dynamic image is generated according to the acquired video clip and the static image.

S212, storing the dynamic image into a system album; the stored dynamic image is used for configuring the dynamic image into dynamic wallpaper through the system photo album.

The system album is configured by default on the terminal and is used for storing static images, source video files and video clips. The dynamic wallpaper is a dynamic image displayed on the terminal screen as a background image. The dynamic wallpaper may be a dynamic image displayed on a main screen of the terminal, or may be a dynamic image displayed on a lock screen of the terminal. It is understood that, in the present embodiment, the dynamic wallpaper configured according to the generated dynamic image includes a dynamic portion and a cover, and a static display state and a dynamic display state also exist. When the specified operation is not detected, the display device is in a static display state, and only the cover is displayed. And when the specified operation is detected, switching to a dynamic display state, and playing the dynamic part according to the playing time sequence. The specified operation can be a pressing operation on a terminal screen or a triggering operation on a preset control.

Specifically, after the terminal generates a corresponding dynamic image according to the video clip added with the first metadata and the static image added with the second metadata, the generated dynamic image is saved in a system album. And when a configuration instruction of the dynamic wallpaper is detected, configuring the dynamic image corresponding to the configuration instruction into the dynamic wallpaper through the system photo album. The configuration instructions may specify a dynamic image configured as a dynamic wallpaper, and may also specify a display location of the dynamic wallpaper. The terminal can configure the dynamic image into the main screen dynamic wallpaper or the locked screen dynamic wallpaper according to the detected configuration instruction, and can also configure the dynamic image into the main screen dynamic wallpaper and the locked screen dynamic wallpaper at the same time.

In one embodiment, after the terminal stores the generated dynamic image into the system album, the terminal enters a preview interface of the dynamic image, and the preview interface comprises a preset control which is triggered and linked to the system album. And when the triggering operation of the preset control is detected, entering a system photo album according to the link, and displaying a cover of the dynamic image which can be configured as dynamic wallpaper. And when a configuration instruction of the dynamic wallpaper is detected, configuring the corresponding dynamic image as the dynamic wallpaper.

According to the video processing method, when the video is processed to generate the corresponding dynamic image, the video clip and the static image are respectively obtained, the first metadata and the second metadata are correspondingly added to the obtained video clip and the static image respectively, so that the video clip added with the first metadata and the static image added with the second metadata are respectively used as the dynamic part and the cover of the dynamic image, and then the dynamic image generated according to the video clip and the static image is stored in the system photo album, so that a user can configure the generated dynamic image into the dynamic wallpaper in the system photo album. The video processing method can process any video into the dynamic image in the specified format so as to realize the effect of configuring the video into the dynamic wallpaper, increase the acquisition sources of the dynamic wallpaper and improve the configuration efficiency of the dynamic wallpaper.

In an embodiment, in the above video processing method, step S202 includes: acquiring a source video file; obtaining a video clip according to a source video file; step S206 includes: a video frame is extracted from a source video file as a still image.

The source video file is a video file which is not processed by the video processing method. The source video file is a video frame set composed of a plurality of video frames in a playback timing. The source video file may be a video file immediately shot by the terminal through a camera, a video file shot by the camera and stored in a system album, or a video file acquired from a browser, a website, or another terminal.

Specifically, when the terminal detects a confirmation instruction for generating a dynamic image, the terminal locally acquires a corresponding source video file and a video clip acquisition instruction corresponding to the acquired source video file according to the detected confirmation instruction, and intercepts a corresponding video clip from the source video file according to the acquired video clip acquisition instruction. The video clip acquisition instruction is an instruction for triggering the interception of a corresponding video clip from a source video file. The video clip retrieval instructions may be used to specify a relative positional relationship between the intercepted video clip and the source video file. The source video file may be a video file that is previously acquired and stored locally.

Further, the terminal acquires a corresponding static image acquisition instruction according to the detected confirmation instruction, and acquires a corresponding video frame from a corresponding source video file according to the acquired static image acquisition instruction, wherein the acquired video frame is the acquired static image. The still image acquisition instructions are used to specify the location (or corresponding timestamp) of the acquired still image in the corresponding source video file.

In one embodiment, when the terminal detects a source video selection operation without detecting a confirmation instruction, the terminal acquires a corresponding source video file according to the detected source video selection operation, and displays the acquired source video file in a designated area according to a playing time sequence. And the terminal detects and acquires the video frames displayed in the designated area, and stores the video clips correspondingly synthesized by the acquired video frames according to the playing time sequence in the local. And the terminal detects and acquires a corresponding time stamp of the first video frame displayed in the designated area in the corresponding source video file, and stores the acquired time stamp. The locally stored video clips can be used as acquisition sources for acquiring the corresponding video clips by the terminal according to the confirmation instructions. The locally stored timestamp can be used as a basis for the terminal to obtain the corresponding static image according to the confirmation instruction.

In the above embodiment, the video clip and the matched still image are respectively acquired from the same source video file, and the acquired video clip and the still image are respectively used as the dynamic part and the cover of the dynamic image, so that the relevance of the dynamic part and the cover of the generated dynamic image is ensured, and the display effect of the dynamic image is improved.

In an embodiment, in the video processing method, the step of obtaining the source video file includes: detecting a video acquisition instruction; calling a system interface according to the video acquisition instruction; and acquiring real-time video frames through a system interface to obtain a video file, or reading a pre-stored video file through the system interface.

The video acquisition instruction is an instruction for triggering acquisition of the source video file.
