And carrying out picture conversion on the target video from the starting time point, calculating the difference value between the picture conversion time point and the starting time point when the picture is converted every time, and taking the difference value as the time stamp of the picture obtained by the picture conversion. And simultaneously, recording the audio stream of the target video from the starting time point, and taking the difference value between the time point of playing the audio clip in the audio stream and the starting time point as the time stamp of the corresponding audio clip. And when the operation of finishing recording is detected, stopping converting the picture and recording the audio stream of the target video.
And 102, synthesizing a plurality of pictures serving as frame images to obtain a video stream.
Specifically, for each picture, the picture is taken as a frame image, wherein the timestamp of the frame image is the timestamp of the picture. And synthesizing the frame images on a time axis of the video according to the sequence of the time stamps of the frame images to obtain the video stream.
And 103, synthesizing the video stream and the audio stream to obtain a recorded video segment.
Specifically, when the video stream and the audio stream are synthesized, time axis synchronization is performed on the time stamp of each audio clip in the audio stream and the time stamp of each frame image in the video stream, so that the recorded video clip is obtained.
As a possible implementation manner, the method provided by this embodiment may be executed by a mobile terminal based on an IOS operating platform, the IOS is a mobile operating system developed by apple, and is mainly used for mobile devices such as iPhone or iPad, and the IOS operating platform provides a method that can generate a specified visual control (UIView) and a contained sub UIView into one picture.
When the user specifies the UIView, the user may specify all uiviews in the screen on which the target video is displayed, or may specify some uiviews, which is not limited in this embodiment.
In the embodiment, a plurality of pictures are obtained by respectively performing picture conversion for a plurality of times in the process of playing the target video, the audio stream of the target video is recorded, the plurality of pictures are synthesized as frame images to obtain the video stream, and then the video stream and the audio stream are synthesized to obtain the recorded video clip, so that the recording of the target video is realized, the technical problem that the mobile terminal cannot record the video clip in the prior art is solved, and the requirement of a user for repeated watching is met through the embodiment of the invention.
To clearly illustrate the previous embodiment, the present embodiment provides another video recording method, where the method provided by the present embodiment can be applied in a live application scenario to record a live video, and fig. 2 is a schematic flow diagram of another video recording method provided by the embodiment of the present invention, and as shown in fig. 2, the video recording method includes the following steps:
Specifically, in the present embodiment, long-pressing the "record screen button" is an operation of starting recording, and when it is detected that the user long-pressing the "record screen button", the video recording task is started. Video recording task the video recording task starts a timer, so as to carry out a plurality of times of picture conversion and record the audio stream of the target video at a certain preset time interval. Since the timestamp of each frame image needs to be determined according to the system time point when the video is generated, the video recording task needs to record the current time point (startTime) of the system as the starting time point when the video recording task starts to be executed.
At step 202, a file is created for saving the recorded video segments.
Specifically, the video recording task creates a file in the file system of the mobile terminal, which is used to store the finally recorded video segment. Generally, the video recording task names the file by using a fixed name, so that as a possible implementation form, if the file with the name does not exist in the file system of the mobile terminal, a file is newly created in the file system. As another implementation form, the file with the name already exists in the file system of the mobile terminal, and after the existing file is deleted, a file with the name is newly built in the file system. After the file is created, the audio stream input source and the video stream input source of the target video are turned on, ready to start recording.
And 203, converting the target video to obtain a picture obtained by converting the picture, and merging the watermark picture to the picture obtained by converting the picture.
Specifically, the video recording task converts each specified visual control in the screen into a corresponding control picture, and then synthesizes each control picture into a picture obtained by converting the picture according to the relative position between each visual control. In this embodiment, after the picture is converted to obtain the picture, the picture may be edited, and the preset watermark picture is superimposed on the picture obtained by the current picture conversion. In this embodiment, the video source graphic identifier may be specifically used as the content of the watermark picture.
And 204, calculating a difference value between the time point of the image conversion and the initial time point, and taking the difference value as a time stamp of the image obtained by the image conversion.
Specifically, the video recording task records a time point of this picture conversion, that is, a difference (Δ vt ═ currentTime-startTime) between a current time point (currentTime) and a starting time point (startTime), and takes the difference (Δ vt) as a timestamp of the picture obtained by this picture conversion.
And step 205, adding the picture obtained by converting the picture as a frame of image in the video stream into the recorded video clip.
Specifically, the video recording task binds the picture obtained by the picture conversion and the timestamp (delta vt) of the picture, further converts the picture into a specific data type of an operating system, obtains a frame of image, and adds the frame of image into the recorded video clip in a video stream mode.
It should be noted that, during the recording process, steps 203 to 207 need to be repeatedly executed until the recording is finished or suspended.
And step 208, stopping picture conversion and recording the audio stream of the target video when detecting that the user executes the operation of finishing recording, and finishing recording.
In this embodiment, the operation of ending the recording is specifically to release the "recording screen button".
Specifically, when the user is detected to perform an operation of releasing the "record screen button", the timer is turned off, the audio stream input source is turned off, and the video recording task is ended.
And 209, synthesizing a preset target picture serving as a frame image with a frame image formed by a plurality of pictures obtained by converting the preset target picture into the picture to obtain a recorded video clip.
Wherein, the target picture can be an advertisement picture.
Specifically, there are at least two possible implementations of synthesizing a preset target picture as a frame image with a frame image formed by a plurality of pictures obtained by converting the preset target picture into the picture.
As a possible implementation manner, a preset target picture is correspondingly superposed on a picture obtained by picture conversion to obtain a synthesized picture; and the transparency of the target picture is reduced along with the increase of the timestamp, and the transparency of the picture obtained by converting the picture is increased along with the increase of the timestamp.
As another possible implementation manner, a preset target picture is added to the multiple pictures obtained by picture conversion, and the target picture and the multiple pictures obtained by picture conversion are synthesized as different frame images.
Generally, the target picture may be synthesized as the last few frames of images, that is, the target picture is inserted after the last picture or several pictures converted from the last picture. Thereby enabling the user to view the promoted advertising information after viewing the recorded video clip.
Further, after previewing, a control for sharing, saving or canceling the video clip is displayed, and a user selects a required operation from the sharing, saving or canceling.
In the embodiment, a plurality of pictures are obtained by respectively performing picture conversion for a plurality of times in the process of playing the target video, the audio stream of the target video is recorded, the plurality of pictures are synthesized as frame images to obtain the video stream, and then the video stream and the audio stream are synthesized to obtain the recorded video clip, so that the recording of the target video is realized, the technical problem that the mobile terminal cannot record the video clip in the prior art is solved, and the requirement of a user for repeated watching is met through the embodiment of the invention.

Specifically, the operation of suspending recording in this embodiment may specifically be clicking a button of "suspend recording screen". When it is detected that the user clicks the "pause recording screen" button, the audio stream for performing the picture conversion and pausing the recording of the target video is paused, that is, the steps 203 to 207 are not performed any more, but the playing of the target video, that is, the playing of the live broadcast in the present embodiment, is not affected.
Specifically, the operation of resuming recording in this embodiment may specifically be clicking a "continue recording screen" button.
