Fig. 1 is a flowchart of a processing method for shooting a file according to an embodiment of the present disclosure, where the embodiment is applicable to a case where an audio file and a video file are played synchronously, and the method may be performed by a processing apparatus for shooting a file, where the apparatus may be implemented by software and/or hardware, and the apparatus may be configured in an electronic device.
Optionally, as shown in fig. 1, the method in this embodiment may include the following steps:
Optionally, mapping the original video file and the original audio file to obtain a time correspondence between the original video file and the original audio file, which may include: determining a first starting time and a first ending time of an original video file; determining a second starting time and a second ending time of the original audio file; and matching and mapping the first starting time and the second starting time, and matching and mapping the first ending time and the second ending time to obtain a time corresponding relation.
Specifically, the first start time, the first end time, the second start time, and the second end time in this embodiment are relative times, and the original video file and the original audio file may be shot files obtained based on a vesdk page. The original video file and the original audio file are shot simultaneously, the obtained duration is the same, but the video track and the audio track are separated when shooting is carried out, so that the original audio file and the original video file obtained through shooting are two files which are independent from each other, are respectively positioned in different addresses and are not related to each other. The method comprises the steps of determining a first starting time and a first ending time of an original video file, and determining a second starting time and a second ending time of an original audio file, namely determining the starting time and the ending time of two types of files respectively, and performing matching mapping respectively. The mapping can correspond the first start time of the original video file to the second start time of the original audio file, and correspond the first end time of the original time-frequency file to the second end time of the original audio file. Because the time lengths of the two types of files are the same, under the condition that the establishment of the corresponding relation between the starting time and the ending time is completed, the time information between the starting time and the ending time in the two types of files naturally corresponds to each other.
And 102, receiving a video editing instruction, and determining a video file to be played according to the video editing instruction.
Optionally, the video editing instruction includes a dragging instruction, and the video file to be played is determined according to the video editing instruction, including: determining the video starting playing time and the video ending playing time of the original video file according to the video editing instruction; and determining the video file to be played from the original video file according to the video starting playing time and the video ending playing time.
Optionally, the video editing instruction includes an adding instruction, and the video file to be played is determined according to the video editing instruction, including: determining the video initial playing time of the original video file according to the video editing instruction; and determining a video file to be played from the original video file according to the video starting playing time and the first ending time.
Specifically, in some application scenarios, the currently playing file contains the original video file, but the user only wants to see a specific portion of the original video file, for example, the original video file is 5 seconds long, and it is expected that the currently playing file starts playing from the 2 nd second of the original video file and ends playing from the 4 th second of the original video file. In these application scenarios, the video file to be played determined by the dragging is a part of the original video file. In other application scenarios, the currently playing file does not contain the original video file, and the user wants to add the original video file at a certain position in the currently playing file. In the application scenes, the video file to be played is added to be the whole content of the original video file, so that different video starting playing time and video ending playing time can be determined according to different types of video editing instructions.
In a specific implementation, when the time length of the original video file is 5 seconds, that is, the first end time is 5 seconds, it is determined that the received video processing instruction is a drag instruction: "drag the original video to start playing from the time of 2 seconds and finish playing from the time of 4 seconds", thereby determining that the video starting playing time is 2 seconds of the original video file and the video ending playing time is 4 seconds of the original video file, thereby determining that the video file to be played is the video content in the time interval of 2 seconds to 4 seconds of the original video file according to the video starting playing time and the video ending playing time, and using the video file in the determined interval range as the video file to be played, namely, the first 2 seconds and the last 1 second of the original video file are not played any more,
in another specific implementation, when the time length of the original video file is 5 seconds, that is, the first ending time is 5 seconds, it is determined that the received time-frequency editing instruction is an adding instruction, "please add the original video file to the currently played video time axis", so that it is determined that the video starting playing time is the starting time of the original video file, and the video ending playing time is the ending time of the original video file, so that the original video file is entirely used as the video file to be played.
It should be noted that in this embodiment, before receiving the video editing instruction, an entry point of the video file on the time axis of the player, that is, a specific playing position on the time axis, is also obtained, and the related information of the video file is also recorded by using a data structure, for example, video segment, and the like, where the entry point and the playing time length of the original video file on the time axis of the player, the entry point and the playing time length of the video file to be played on the time axis of the player, and a storage address of the original video file are stored in the data structure, where the storage addresses of the original video file and the video file to be played are the same. For example, the entry point of the original video file on the time axis of the player is stored in the data structure to be 0 second, and the playing time is 5 seconds; the entry point of a video file to be played on the time axis of the player is 0 second, and the playing time is 3 seconds; the storage address of the original video file is abc.
Optionally, the video editing instruction includes a deletion instruction, and determining a video file to be played according to the video editing instruction may include: determining the point-in time and the point-out time of an original video file on the current video playing time axis according to the video editing instruction; and deleting the original video files positioned in the range of the point-in time and the point-out time on the time axis of the currently played video, and taking the residual currently played video files as video files to be played.
Specifically, in this embodiment, the video editing instruction may further include a deletion instruction, that is, the current video timeline includes the original video file, and may be a part of the original video file or may be the entire content of the original video file, but after receiving the deletion instruction, it is described that the relevant content on the original video file on the current video timeline needs to be deleted. For example, the time length of the original video file is 5 seconds, the video editing instruction is "delete the original video file of 4 seconds to 9 seconds on the current playing video time axis", wherein 4 seconds is the point-in time on the current playing video time axis, and 9 seconds is the point-out time on the current video time axis, then delete the original video file located in the range of 4 seconds and 9 seconds on the current playing video time axis, and use the remaining current playing video file as the video file to be played.
And 103, determining an audio file to be played according to the corresponding relation between the video file to be played and the time.
Optionally, determining the audio file to be played according to the corresponding relationship between the video file to be played and the time may include: acquiring an audio starting playing time corresponding to a video starting playing time and an audio ending playing time corresponding to a video ending playing time from a time corresponding relation; and determining the audio file to be played according to the audio starting playing time and the audio ending playing time.
Optionally, determining the audio file to be played according to the corresponding relationship between the video file to be played and the time may include: acquiring an audio initial playing time corresponding to the video initial playing time from the time corresponding relation; and determining the audio file to be played according to the audio initial playing time and the second ending time.
Optionally, after determining the audio file to be played according to the corresponding relationship between the video file to be played and the time, the method further includes: and storing the video file to be played and the audio file to be played locally.
Specifically, after the video file to be played is determined, in order to ensure the consistency between the sound and the picture, the audio file to be played needs to be determined according to the corresponding relationship between the video file to be played and the time,
for example, when the video file to be played is determined by the drag instruction, since the time lengths of the original audio file and the original video file are the same, the time length of the original audio file is also 5 seconds, and if the determined video start playing time of the video file to be played is 2 seconds of the original video file, the video end playing time is 4 seconds of the original video file. According to the time corresponding relation between the original video file and the original audio file, the audio starting playing time corresponding to the video starting playing time of 2 seconds is acquired to be 2 seconds of the original audio file, the audio ending playing time corresponding to the video ending playing time of 4 seconds is acquired to be 4 seconds of the original audio file, and therefore the audio file to be played is determined to be the audio file in the time interval of 2 seconds to 4 seconds of the original audio file according to the audio starting playing time and the audio ending time. Since the manner of determining the audio file to be played by adding the instruction is substantially the same as this, details are not repeated in this embodiment.
Specifically, the video file to be played and the audio file to be played in the embodiment are stored locally, a data structure video segment is used for recording a storage address of the video file to be played, and the storage address of the video file to be played is the same as that of the original video file.
Optionally, determining the audio file to be played according to the corresponding relationship between the video file to be played and the time may include: determining an original audio file corresponding to the original video file deleted based on the deletion instruction according to the time corresponding relation; and deleting the determined original audio file on the currently played audio time axis, and taking the remaining currently played audio file as an audio file to be played, wherein the currently played audio time axis is overlapped with the currently played video time axis.
Specifically, after the video file to be played is determined by the deletion instruction, the original audio file corresponding to the original video file deleted based on the deletion instruction is determined according to the time correspondence relationship, for example, the deleted original video file is within the range of 0 second to 5 seconds, the original audio file to be deleted is determined according to the time correspondence relationship, and the determined original audio file is deleted on the current playing audio time axis because the current playing audio time axis and the current playing video time axis are overlapped, so that the video file is deleted, the audio file corresponding to the video file is deleted, and the condition that the sound and the picture are inconsistent is avoided.
And step 104, synchronously playing the video file to be played and the audio file to be played through the player.
Optionally, before the synchronous playing of the video file to be played and the audio file to be played by the player, the method may further include: and acquiring a synchronous playing instruction for the video file to be played and the audio file to be played.
Optionally, the playing the video file to be played and the audio file to be played synchronously by the player may include: in response to receiving a synchronous playing instruction sent by a player, extracting a video file to be played and an audio file to be played from the local; and transmitting the video file to be played and the audio file to be played to the player so that the player can synchronously play the video file to be played and the audio file to be played.
It should be noted that, when the video file to be played and the audio file to be played are played synchronously by the player, specifically, an entry point of the video file to be played on the time axis of the player is determined according to the data structure, and the video file to be played is played at the determined entry point. And the same access point is adopted for the audio file to be played and the video file to be played, namely the access point of the audio file to be played on the time axis of the player is determined according to the access point of the video file to be played. When a synchronous playing instruction sent by the player is determined to be received, the video file to be played and the audio file to be played are extracted from the local area, the video file to be played and the audio file to be played are transmitted to the player, and the video file to be played and the audio file to be played are played synchronously at the same determined entry point on the time axis of the player.
Optionally, the synchronous playing of the video file to be played and the audio file to be played by the player may include sending play trigger information to the player in response to receiving a synchronous play instruction sent by the player, so that the player can synchronously play the video file to be played and the audio file to be played which remain after deletion.
Specifically, when the video file to be played and the audio file to be played are determined by the deletion instruction, the file from which the original video file is deleted is used as the video file to be played and the file from which the original audio file is deleted is used as the audio file to be played, so that the original audio file or the original video file does not need to be acquired locally, and only the video file and the audio file reserved in the player after deletion need to be transmitted, so that the player only needs to transmit play trigger information to the player in this case, and the player can synchronously play the video file to be played and the audio file to be played which are left after deletion.
The embodiment provides a processing method for shooting files, which is characterized in that a time corresponding relation between an original video file and an original audio file is established, so that when a player plays an acquired video file to be played and an acquired audio file to be played, pictures and sounds are matched at each time, the situation that the pictures and the sounds are inconsistent cannot occur, and the experience effect of a user is improved.
