In the related technology of synchronous recording and playing of terminal videos, a picture for recording a video and a picture for playing the video exist in a display screen of a terminal, and the picture for playing the video often has a black background edge, so that visual proportion of a picture boundary for recording the video and a picture boundary for playing the video is not coordinated, the picture aesthetic feeling is insufficient when a video is finally synthesized into a new video, and the quality of the playing picture of the playing video is reduced.
The embodiment of the disclosure provides a method for processing video data, and aims to solve the problems that when a conventional terminal plays a video, the ratio of the boundary of a playing picture of a recorded video to the boundary of the playing picture of the played video is not coordinated, so that the playing picture of a synthesized video is not attractive, and the quality of the playing picture is influenced.
The technical solution of the present disclosure is explained in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart illustrating a method for processing video data according to an embodiment. The embodiment relates to a specific process of adding filling data on the basis of playing video data and then processing recorded video data, played video data and filling data so as to improve the picture quality of a composite video. As shown in fig. 2, the method comprises the steps of:
s101, acquiring recorded video data, playing video data and filling data; the filling data is used for filling the non-video area in the picture corresponding to the playing video data.
The recorded video data is obtained by acquiring image data of a shot picture by a camera on the terminal when a user records a video by using the terminal. The played video data may be recorded video data pre-stored in the terminal, or alternatively, may also be video data acquired by downloading from the network after the terminal connects to the network, or alternatively, may also be video data transmitted from another terminal device through another communication connection manner, which is not limited in this embodiment. The filling data can be one or a combination of characters, pictures, videos and the like. The specific form of the padding data can be customized by a user, and optionally, can also be determined by a preset type of the padding data. The filling data may be data pre-stored in the terminal cache, or may be data downloaded from a network or acquired from other devices. The non-video area may be an area where there is no moving picture in the picture on which the video is played, for example, an area where a background edge such as black or white is located in the picture on which the video is played, or alternatively, an area corresponding to a still picture in the picture on which the video is played. Accordingly, the position of the frame of the padding data may be set in the area where the background side such as black, white, etc. in the frame of the playing video is located, or optionally, may also be set in the area corresponding to the still frame in the frame of the playing video.
In this embodiment, when a user records a video using a terminal, the user may first obtain played video data on the terminal, obtain recorded video data through an image data acquisition device of a camera of a mobile phone, and simultaneously, the user may also input an instruction for setting the padding data on the mobile phone before recording the video or after recording the video, so that the terminal may obtain the padding data according to the instruction information, or the terminal selects the padding data matched with a non-video area in a picture corresponding to the played video data according to a preset rule, and finally performs synthesis processing on the played video data, the recorded video data, and the padding data, and further performs playing in a screen of the terminal.
And S102, displaying the recorded video data, the played video data and the filling data in a display area of the terminal according to the picture layout rule.
The picture layout rule refers to the arrangement mode of pictures of the recorded video data, the played video data and the filled data in the display area on the terminal screen when the recorded video data, the played video data and the filled data are played in the display area on the terminal screen. The arrangement mode may include the position, shape, size, resolution, etc. of the picture for recording video data, the picture for playing video data, and the picture for filling data on the screen. The picture layout rule may be preset in the terminal, or alternatively, the picture layout rule may also be set by the terminal in a user-defined manner before the terminal performs the synthesizing process on the recorded video data, the played video data, and the padding data to generate the synthesized video, which is not limited in this embodiment. In addition, the arrangement may be various, for example, as shown in fig. 2a, the picture for recording the video data and the picture for playing the video data are arranged horizontally, and the picture for filling the data and the picture for playing the video data are arranged vertically, and vertically. For another example, as shown in fig. 2b, the frame for recording video data and the frame for playing video data are arranged vertically, and the frame for filling data and the frame for playing video data are arranged horizontally. This embodiment does not limit the arrangement position.
In this embodiment, when a user records a video using a terminal, and after acquiring a recorded video, a played video, and padding data, the recorded video, the played video, and the padding data are synthesized to generate synthesized video data, so that the terminal can play the synthesized video on a screen. The pictures for recording video data, playing video data and filling data can be arranged according to the picture layout rule and displayed in the display area on the user terminal. For example, as shown in fig. 2a, the screen layout rule set by the terminal may be that the display area is divided into two left and right areas with equal size, and the right area is further divided into three upper, middle and lower areas, wherein the left area may display a screen for recording video data, the middle area in the right area may display a screen for playing video data, and the upper and lower areas in the right area may respectively display a screen for filling data. After the terminal arranges the video pictures of the recorded video data, the played video data and the filling data according to the picture layout rule, the picture of the recorded video data is displayed in the left area in the display area on the terminal, the picture of the played video data is displayed in the middle area in the right area in the display area on the terminal, and the picture of the filling data is displayed in the upper area and the lower area in the right area in the display area on the terminal.
In the above embodiment, the terminal acquires recorded video data, played video data, and padding data; the filling data is used for filling a non-video area in a picture corresponding to the playing video data; and displaying the recorded video data, the played video data and the filling data in a display area of the terminal according to a picture layout rule. In the method for processing the video data, the filling data is added in the non-video area in the picture corresponding to the played video data by the terminal, so that the filling data and the played video data are combined into a new video data, and a new video picture is formed, and the proportion of the new video picture is added due to the filling data, so that the filling data can cover the non-video area in the played video data, and the picture edge of the recorded video data and the picture edge of the played video data are more harmonious in display proportion, thereby improving the quality of the combined video picture.
Fig. 3 is a schematic flowchart of an implementation manner of S102 in the embodiment of fig. 2, and the embodiment mainly relates to a specific process in which a terminal performs synthesis processing on a plurality of pieces of video data, and then plays a synthesized video obtained after the synthesis processing by using a player. On the basis of the foregoing embodiment, as shown in fig. 2, the foregoing S102 "displaying the recorded video data, the played video data, and the padding data in the display area of the terminal according to the screen layout rule" includes the following steps:
s201, synthesizing the recorded video data, the played video data and the filling data by adopting a preset image processing method according to the picture layout rule to obtain synthesized video data.
The preset image processing method may include an image processing method in which a picture for recording video data, a picture for playing video data, and a picture for filling data are arranged according to a picture layout rule; an image processing method for synchronously displaying all video images is carried out on the recorded video data, the played video data and the filling data; and carrying out splicing processing on the recorded video frame images, the played video frame images and the filled data frame images and the like. The composite video data is new video data formed by image processing a plurality of video data by the terminal using an image processing method.
In this embodiment, a user may pre-define a picture layout rule on the terminal, or after acquiring corresponding recorded video data, played video data, and padding data, pre-define a picture layout rule on the terminal through an instruction input terminal, then perform image processing on the recorded video data, the played video data, and the padding data by using an image processing device on the terminal, so as to lay out display positions of pictures of the recorded video data, the played video data, and the padded data in a display area in a terminal screen, that is, arrange according to the user-defined picture layout rule. And then the arranged recorded video data, the arranged played video data and the arranged filling data are subjected to image synthesis processing, and finally synthesized video data are generated.
Optionally, in one embodiment, the screen layout rule includes a screen layout rule of a display area when recording a video or a layout rule generated according to a control instruction input by a user.
In this embodiment, when a user records a video using a terminal, a display area in a terminal screen may include a picture for recording video data, a picture for playing video data, and a picture for filling data, and positions of the picture for recording video data, the picture for playing video data, and the picture for filling data in the display area may be set by the terminal according to a fixed picture layout rule before the user records the video, or may be set by the terminal according to a layout rule generated by a control instruction input by the user before the terminal records the video. As another alternative, after the terminal records the video, the terminal sets the positions of the picture for recording the video data, the picture for playing the video data, and the picture for filling the data in the display area according to the layout rule generated by the control instruction input by the user. The method for customizing the picture layout rule by the user strengthens the interactivity between the user and the terminal video, improves the experience degree of the user on the video picture, and simultaneously improves the ornamental property of the video picture through the setting of the user.
S202, controlling a player to play the synthesized video data in the display area.
Wherein, the terminal can control a player to play video data.
In this embodiment, when the terminal performs image processing on the recorded video data, the played video data, and the padding data, and generates the composite video data, the terminal controls a player thereon to convert the composite video data into an image for playing, and displays a picture of the recorded video data, a picture of the played video data, and a picture of the padding data in a display picture of the composite video data, and the player can display the picture of the recorded video data, the picture of the played video data, and the picture of the padding data at different positions of the display area according to the above picture layout rule.
In the above embodiment, the terminal performs synthesis processing on the recorded video data, the played video data, and the padding data by using a preset image processing method according to the picture layout rule to obtain synthesized video data; a player is controlled to play the composite video data in the display area. Since the screen layout rule may be a screen layout rule preset by the terminal, optionally, the screen layout rule may also be set by the user before recording the video. Therefore, the flexible arrangement of the picture for recording the video data, the picture for playing the video data and the picture for filling the data can be realized according to the picture layout rule, the interactivity between the user and the mobile phone video is enhanced, and the layout positions of the picture for recording the video data, the picture for playing the video data and the picture for filling the data can be adjusted through the setting of the picture layout rule, so that the proportion of each picture in the picture for synthesizing the video data is more harmonious visually, and the picture quality of the synthesized video data is improved.
In particular, one embodiment relates to a specific process for composing video data. As shown in fig. 4, in S201, "synthesizing the recorded video data, the played video data, and the padding data by using a preset image processing method according to the picture layout rule to obtain synthesized video data", the method may specifically include the following steps:
s301, according to the recorded video data, the played video data and the filling data, respectively acquiring recorded video frame images, played video frame images and filled video frame images corresponding to the timestamps.
Where the timestamp may identify a time of a moment, e.g., 17 hours, 17 minutes, 17 seconds. The recorded video frame image corresponding to the timestamp refers to a frame of recorded video image acquired by the image acquisition device at a specific time; the playing video frame image corresponding to the timestamp refers to a frame playing video image at a certain specific time; the filling video image corresponding to the time stamp refers to a frame filling video image at a specific time.
In this embodiment, in the process of image processing of the acquired recorded video data, played video data, and filler data by the terminal, the terminal may first determine a plurality of timestamps according to the video playing duration of the synthesized video data, and then extract the recorded video frame image, the played video frame image, and the filler video frame image corresponding to each timestamp from the recorded video data, the played video data, and the filler data according to each timestamp. Wherein the plurality of timestamps comprise a total duration equal to the video playback duration of the composite video data.
And S302, synthesizing the recorded video frame image, the played video frame image and the filled video frame image corresponding to each timestamp according to the picture layout rule to generate synthesized video data.
In this embodiment, when the terminal performs image processing on the recorded video data, the played video data, and the padding data by using the image processing apparatus, a plurality of timestamps are first set according to a video playing duration of the synthesized video data, the recorded video frame image, the played video frame image, and the padding video frame image corresponding to each timestamp are then obtained according to each timestamp, and finally the recorded video frame image, the played video frame image, and the padding video frame image corresponding to each timestamp are synthesized according to the above-mentioned frame layout rule, so as to further generate the synthesized video data. For example, when the video playing duration of the synthesized video data is 5s, 10 timestamps in units of 0.5s may be set, and then according to the 10 timestamps, each frame image corresponding to the 10 timestamps is found from the recorded video frame image, the played video frame image, and the filler video frame image, and finally, the recorded video frame image, the played video frame image, and the filler video frame image corresponding to the same timestamp are synthesized, so that the synthesis of all the recorded video frame images, the played video frame images, and the filler video frame images is completed together.
Optionally, one embodiment further describes a specific process of synthesizing video data. As shown in fig. 5, the synthesizing process is performed on the recorded video frame image, the played video frame image, and the filled video frame image corresponding to each timestamp according to the picture layout rule to generate synthesized video data, and the specific method may include:
s401, arranging the recorded video frame images, the played video frame images and the filled video frame images corresponding to the timestamps according to the picture layout rule to obtain the video frame images corresponding to the timestamps.
The video frame images corresponding to the timestamps are synthesized video frame images which are synthesized after recording the video frame images, playing the video frame images and filling the video frame images are arranged according to the picture layout rule, and are single-frame synthesized video frame images.
In this embodiment, after the terminal acquires the recorded video frame image, the played video frame image, and the filled video frame image corresponding to each timestamp by using the image processing device according to the set timestamps, the recorded video frame image, the played video frame image, and the filled video frame image corresponding to each timestamp are arranged according to the above-mentioned picture layout rule, so that the video frame images corresponding to the arranged timestamps can be generated.
S402, according to the sequence of the timestamps, splicing the video frame images corresponding to the timestamps to obtain the synthesized video data.
Because the time stamp is a concept of time, there is a chronological order, and the time length included in the plurality of time stamps may be equal to a period of time length. For example, the video playback time length of the composite video data in the present embodiment may include a plurality of time stamps, and the sum of the video data corresponding to the plurality of time stamps constitutes the composite video data.
In this embodiment, when the terminal needs to perform synthesis processing on the recorded video frame image, the played video frame image, and the filler video frame image corresponding to each timestamp, it is first necessary to arrange the recorded video frame image, the played video frame image, and the filler video frame image according to the above-mentioned picture layout rule, and generate the video frame image corresponding to each timestamp, so that the picture of the recorded video data, the picture of the played video data, and the picture of the filler data can be arranged in the display area of the terminal according to the above-mentioned picture layout rule. And then, when the terminal needs to splice the video frame images corresponding to the time stamps, sequencing the time stamps according to the time sequence, sequencing the video frame images corresponding to the time stamps according to the time sequence of the time stamps, and finally splicing the sequenced video frame images to generate a video data stream to obtain the synthesized video data.
Optionally, in one embodiment, the step S102 in the embodiment of fig. 2 "displaying the recorded video data, the played video data, and the padding data in the display area of the terminal according to the screen layout rule" may further include: and controlling a plurality of players to play and record video data, play video data and fill data at different positions in the display area respectively according to the picture layout rule.
In this embodiment, when the terminal needs to simultaneously display the picture of recording the video data, the picture of playing the video data, and the picture of filling the data on the display screen, the terminal can control the three players to play the picture of recording the video data, the picture of playing the video data, and the picture of filling the data, respectively. Optionally, the terminal may also control the two players to play the picture of the recorded video, the picture of the played video, and the picture of the padding data, respectively. And the terminal can further control a plurality of players to set the positions of the pictures of the corresponding video data in the display area of the display screen, the size of the occupied display area and the like according to the picture layout rule when the video corresponding to each player is played. The method does not need to synthesize the acquired recorded video data, the acquired played video data and the acquired filling data and then play and display the video pictures, so that the process of data processing can be reduced by using the method to display the pictures of a plurality of videos, thereby saving resources and reducing the processing time of a terminal on the plurality of video data.
In the embodiment of fig. 2, the terminal needs to acquire the recorded video data, the played video data and the padding data before playing the composite video. When the user sets the padding data on the terminal, the subsequent composite video data includes the padding data, and it should be noted that all the above embodiments are based on a scenario in which the user sets the padding data on the mobile phone. The following embodiment illustrates a process for a terminal to obtain padding data. Specifically, in one embodiment, as shown in fig. 6, the acquiring the padding data includes:
s501, when a filling data acquisition instruction input by a user is received, displaying a filling data selection interface in a display area; the selection interface includes a plurality of fill data types.
The stuffing data acquisition instruction is instruction information input by a user on the terminal, and is specifically used for enabling the user to set the type of stuffing data. The input mode of the instruction information may be a mode in which the user clicks a control on the touch screen, optionally, a mode in which the user inputs the instruction information by voice, which is not limited in this embodiment.
