It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.

Fig. 1 illustrates an exemplary system architecture 100 to which the method for recording video or the apparatus for recording video of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
A user may use the terminal devices 101, 102, 103 to interact with the server 105 over the network 104 to receive or send messages (e.g., audio video data upload requests, audio data acquisition requests), etc. Various communication client applications, such as a video recording application, an audio playing application, a video encoding application instant messaging tool, a mailbox client, social platform software, and the like, may be installed on the terminal devices 101, 102, and 103.
The terminal apparatuses 101, 102, and 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices having a display screen and video recording and audio playing, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like. When the terminal apparatuses 101, 102, 103 are software, they can be installed in the electronic apparatuses listed above. It may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services) or as a single piece of software or software module. And is not particularly limited herein.
The terminal devices 101, 102, 103 may be equipped with an image capturing device (e.g., a camera) to capture video data. In practice, the smallest visual unit that makes up a video is a Frame (Frame). Each frame is a static image. Temporally successive sequences of frames are composited together to form a motion video. Further, the terminal apparatuses 101, 102, 103 may also be mounted with a device (e.g., a speaker) for converting an electric signal into sound to play the sound. In practice, the audio data is data obtained by performing analog-to-Digital Conversion (ADC) on an analog audio signal at a certain frequency. The audio data playing is a process of performing digital-to-analog conversion on a digital audio signal, restoring the digital audio signal into an analog audio signal, and converting the analog audio signal (the analog audio signal is an electrical signal) into sound for output.
The terminal apparatuses 101, 102, 103 can perform acquisition of video data with an image acquisition device (e.g., a camera) mounted thereon. Also, encoding of video data may be performed using a video encoder installed thereon. In addition, the audio player installed thereon can also be used for playing the audio data. The terminal apparatuses 101, 102, 103 can control, set, and the like a video encoder, an audio player, and the like.
The server 105 may be a server providing various services, such as a background server providing support for video recording type applications installed on the terminal devices 101, 102, 103. The background server can analyze and store the received data such as the audio and video data uploading request and the like. And audio and video data acquisition requests sent by the terminal equipment 101, 102 and 103 can be received, and the audio and video data indicated by the audio and video data acquisition requests are fed back to the terminal equipment 101, 102 and 103.
The server may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster formed by multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be noted that the method for recording video provided in the embodiment of the present application is generally executed by the terminal devices 101, 102, and 103, and accordingly, the apparatus for recording video is generally disposed in the terminal devices 101, 102, and 103.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for recording video in accordance with the present application is shown. The method for recording the video comprises the following steps:
In the present embodiment, the execution subject of the method for recording a video (e.g., the terminal apparatuses 101, 102, 103 shown in fig. 1) may acquire and store target audio data in advance. Here, the target audio data may be audio data (voice data) of a soundtrack designated as a video in advance by a user, for example, audio data corresponding to a certain designated song. The execution body may have a video encoder installed or disposed therein. The video encoder may be used in practice of encoding video data, and video encoding refers to a mode of converting a file in a certain video format into a file in another video format through a specific compression technology. The video encoder may be implemented in existing software (e.g., a component, a code module, etc.) or hardware, and is not limited thereto.
In response to detecting the recording resuming instruction, a duration of the video encoded by the video encoder may be determined, and the playing progress of the audio player may be set to the duration. Wherein, the recording resuming instruction can be used to instruct to continue to collect the video data and to continue to play the target audio data by using the audio player. Here, before the recording command is resumed, the execution body may store a pre-recorded video that is not recorded. Here, the pre-recorded video has been encoded by a video encoder. The execution body may determine a duration of video encoded by the video encoder. In practice, the duration of the video encoded by the video encoder during each recording process can be determined as follows: firstly, determining the starting time and the stopping time of transmitting data to a video encoder by the recording; and then, determining the difference value between the stop time and the start time as the time length of the video coded by the video coder in the recording process. In practice, the time duration may also be regarded as the time duration of the successfully recorded video. And summing the time lengths of the coded videos in the recording processes, so as to obtain the time length of the coded video of the video coder.
It should be noted that the execution main body may also use other methods to determine the time length of the recorded video, and details are not described here.
It should be noted that, if the execution main body does not store the video that is not recorded in advance and is not recorded completely, that is, the execution main body is in the process of recording the first video, the playing progress may be directly set to 0. At this time, playback is started from the start position of the target audio data.
In practice, audio data is data obtained by digitizing a sound signal. The digitization of the sound signal is a process of converting a continuous analog audio signal into a digital signal at a certain frequency to obtain audio data. Generally, the process of digitizing a sound signal comprises three steps of sampling, quantizing and encoding. Here, sampling is to replace an original signal that is continuous in time with a sequence of signal sample values at regular intervals. Quantization is the approximation of the original amplitude value which changes continuously in time by a finite amplitude, and the continuous amplitude of the analog signal is changed into a finite number of discrete values with a certain time interval. The encoding means that the quantized discrete values are represented by binary numbers according to a certain rule. Here, Pulse Code Modulation (PCM) may implement digitized audio data into which an analog audio signal is sampled, quantized, and encoded. Accordingly, the above target audio data may be a data stream in a PCM encoding format. At this time, the format of the file in which the target audio data is described may be the wav format. The format of the file describing the target audio data may be other formats, such as mp3 format and ape format. At this time, the target Audio data may be data in other encoding formats (for example, lossy compression formats such as AAC (Advanced Audio Coding)), and is not limited to the PCM encoding format. The execution body may also perform format conversion on the file to convert the file into a record wav format. At this time, the target audio file in the converted file is a data stream in PCM coding format.
Generally, the execution body may be installed with a video recording application. The video recording application can support recording of the dubbing music video. The dubbing music video can be a video which is played by audio data at the same time of video data acquisition. And the recorded sound in the dubbing music video is the sound corresponding to the audio data. For example, a singing action performed by a user is recorded during the process of playing a certain song, and the recorded video takes the song as background music. The video recording application can support continuous recording and segmented recording of the dubbing music video. When recording in segments, a user may first click a recording button to record a first segment of video. Then, the recording button is clicked again to trigger the instruction of suspending video recording. And then clicking the recording key again to trigger a recording resuming instruction so as to record the second video segment. Then, the recording button is clicked again to trigger the instruction of suspending video recording. And so on. It should be noted that the recording instruction, the recording pause instruction, and the recording resume instruction may also be triggered by other manners. For example, each video can be recorded by pressing a record button for a long time. When the recording button is released, an instruction for suspending video recording is triggered. And will not be described in detail herein.
In this embodiment, an audio player may be installed or disposed in the execution body. The audio player is used for playing audio data. In practice, audio playback is a process of performing digital-to-analog conversion on digitized audio data and restoring the converted audio data into an analog audio signal. The audio player may be implemented in existing software (e.g., a component, a code module, etc.) or hardware, and is not limited thereto.
In this embodiment, after step 201 is executed, the execution subject may start the video encoder and the audio player in sequence. I.e. the video encoder is started first. And starting the audio player after the video encoder is successfully started. It should be noted that, if the audio player is started first and then the video encoder is started, or the audio player and the video encoder are started simultaneously, the video encoder may not be started successfully when the target audio data is played to the playing progress, so that the playing of the target audio data is not synchronized with the encoding of the video data. And after the video encoder is started successfully, the audio player is started, so that the situation can be avoided. In practice, the execution body may control the start or stop of the video encoder and the audio decoder.
And 203, after the target audio data is played to the playing progress, responding to the collected video data, and transmitting the collected video data to the video encoder so that the video encoder encodes the collected video data.
In this embodiment, after the target audio data is played to the playing progress, in response to the collected video data, the collected video data may be transmitted to the video encoder, so that the video encoder encodes the collected video data. Therefore, after the target audio data is played to the playing progress, the video data is formally encoded, so that the audio data is played and the video data is encoded synchronously, and the audio and video synchronization effect in the recording process of the dubbing music video is improved.
In practice, the execution body may be equipped with an image acquisition device, such as a camera. The execution main body can acquire video data by using the camera.
In some optional implementations of this embodiment, before the target audio data is played to the playing progress, in response to capturing the video data, the execution subject may delete the captured video data. In practice, the executing body may collect video data by using the camera. Before the above step 201 is executed, that is, before the recording resuming instruction is detected, the camera may be in an on state or an off state. If the target audio data is in the on state, the image capturing may be continued, but the captured image is not transmitted to the video encoder, or the captured image is not stored, and may be discarded (i.e., frame dropping processing is performed) until the target audio data is played to the playing progress. If the camera is in the off state before the recording resuming instruction is detected, the camera can be turned on for image capturing after the recording resuming instruction is detected. At this time, the captured frames are also discarded until the target audio data is played to the playing progress.
In some optional implementation manners of this embodiment, the method for recording a video may further include the following steps: and in response to the detected recording stopping instruction, stopping transmitting the collected video data to the video encoder, and controlling the audio player to stop playing. And then, controlling the video encoder to stop encoding.
In some optional implementations of this embodiment, after the controlling the video encoder to stop encoding, the method for recording a video may further include: first, the total duration of video data that has been encoded by the video encoder is determined. Here, the total duration of the encoded video data is the total duration of the video data that can be currently recorded. Then, the total duration may be determined as a final playing progress of the audio player. It should be noted that the encoded video data includes video data recorded before step 201.
In some optional implementation manners of this embodiment, after the determining the total duration as the final playing progress of the audio player, the method for recording a video may further include: firstly, the played target audio data indicated by the final playing progress is taken as a target audio data interval, and the target audio data interval is extracted. Here, the playing end position of the target audio data corresponding to the playing progress may be determined. And taking a section formed from the playing starting position to the playing ending position of the target audio data as a target audio data section, and extracting the target audio data section. The encoded video data and the target audio data interval may then be stored. Here, the target audio data interval and the encoded video data may be stored in two files, respectively, and a mapping between the two files may be established. In addition, the target audio data interval and the encoded video data may be stored in the same file.
In some optional implementation manners of this embodiment, the method for recording a video may further include: in response to detecting the recording resuming instruction, the pre-established code flag is set to a first preset value (e.g., "NO", or "N", or "0", etc.). The first preset value may be used to indicate that the currently acquired video data is deleted.
In some optional implementation manners of this embodiment, the method for recording a video may further include: when the target audio data is played to the playing progress, the encoding flag is set to a second preset value (for example, "YES", or "Y", or "1", etc.). The second preset value may be used to instruct the video encoder to transmit currently acquired video data.
In some optional implementation manners of this embodiment, the method for recording a video may further include: and responding to the detected recording stopping instruction, and setting the code identification to be the first preset value.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for recording a video according to the present embodiment. In the application scenario of fig. 3, the user holds the terminal device 301 and records the dubbing video. The terminal device 301 runs a short video recording application. The user selects a certain score (for example, song "small apple") in the interface of the short video recording application in advance, and records the score video in a segmented manner. The score corresponds to the target audio data 302. After a certain segment is recorded, after a user clicks a dubbing video recording button, a recording recovery instruction is triggered. After detecting the recording resuming instruction, the terminal device 301 sets the playing progress of the audio player to the duration of the video encoded by the video encoder. And then, the video encoder and the audio player are sequentially started, and after the target audio data is played to the playing progress, the collected video data is transmitted to the video encoder in response to the collected video data 303, so that the video encoder encodes the collected video data.
In the method provided by the above embodiment of the present application, after the recording resuming instruction is detected, the playing schedule of the audio player is set to the duration of the recorded video, and then the video encoder and the audio player are sequentially started, and after the target audio data is played to the playing schedule, the collected video data is transmitted to the video encoder in response to the collected video data, so that the video encoder encodes the collected video data. Therefore, the duration of the recorded video can be set as the playing progress of the audio player, and the condition that the recorded video is not synchronized with the audio and video due to the deviation of the playing progress is avoided. Meanwhile, the video encoder is started in advance, and when the target audio data is played to the playing progress, the collected video data is transmitted to the video encoder, so that the video data encoding and the audio data playing are synchronously performed, and the audio and video synchronization effect in the recording process of the dubbing music video is improved.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for recording video is shown. The process 400 of the method for recording video includes the steps of:
in step 401, in response to detecting the recording resuming instruction, a duration of the video encoded by the video encoder is determined, and a playing progress of the audio player is set to the duration.
In the present embodiment, a video encoder may be installed or disposed in an execution body (e.g., terminal apparatuses 101, 102, 103 shown in fig. 1) of the method for recording a video. And in response to detecting the recording resuming instruction, determining the time length coded by the video coder, and setting the playing progress of the audio player to the time length. Wherein, the recording resuming instruction can be used to instruct to continue to collect the video data and to continue to play the target audio data by using the audio player.
In this embodiment, in response to detecting the recording resuming instruction, the executing entity may further set a pre-established code flag to be a first preset value (e.g., "NO", or "N", or "0", etc.). The first preset value may be used to indicate that the currently acquired video data is deleted.
In this embodiment, the execution body may be mounted with an image capture device, such as a camera. The execution main body can acquire video data by using the camera. Before the above step 401 is executed, that is, before the recording resuming instruction is detected, the camera may be in an opened state. The execution body may continuously perform image acquisition using the camera. In response to capturing video data (i.e., capturing each frame), it may be determined whether a value of a current coding flag is the first preset value, and the currently captured video data may be deleted (i.e., frame dropping processing is performed) until the value of the coding flag is a second preset value (e.g., "YES", or "Y", or "1", etc.). The second preset value may be used to instruct the video encoder to transmit currently acquired video data.
In this embodiment, an audio player may be installed or disposed in the execution body. The execution body may sequentially start the video encoder and the audio player. I.e. the video encoder is started first. And starting the audio player after the video encoder is successfully started.
And step 403, after the target audio data is played to the playing progress, in response to the collected video data, transmitting the collected video data to the video encoder, so that the video encoder encodes the collected video data.
In this embodiment, after the target audio data is played to the playing progress, in response to the collected video data, the collected video data may be transmitted to the video encoder, so that the video encoder encodes the collected video data. Therefore, after the target audio data is played to the playing progress, the video data is formally encoded, so that the audio data is played and the video data is encoded synchronously, and the audio and video synchronization effect in the recording process of the dubbing music video is improved.
In addition, when the target audio data is played to the playing progress, the execution main body may further set the encoding flag to the second preset value to indicate that, when video data is collected, the currently collected video data is transmitted to the video encoder.
In this embodiment, in response to detecting the recording stop instruction, the execution main body may stop transmitting the collected video data to the video encoder, and simultaneously, control the audio player to stop playing.
In addition, in response to detecting the recording stopping instruction, the executing body may further set the code identifier to the first preset value to indicate that the video data captured continuously is discarded when the video data is captured continuously.
In this embodiment, after stopping transmitting the collected video data to the video encoder and controlling the audio player to stop playing, the execution main body may control the video encoder to stop encoding. I.e. stop the video encoder.
At step 406, the total duration of video data that has been encoded by the video encoder is determined.
In this embodiment, after controlling the video encoder to stop encoding, the execution body may determine a total duration of the video data encoded by the video encoder. Here, the total duration of the encoded video data is the total duration of the video data that can be currently recorded. The encoded video data includes the video data recorded before step 201.
In this embodiment, the execution subject may determine the determined total duration as the final playing progress of the audio player.
And step 408, taking the played target audio data indicated by the final playing progress as a target audio data interval, and extracting the target audio data interval.
In this embodiment, the execution main body may first determine a playing end position of the target audio data corresponding to the playing progress. Then, a section from the play start position to the play end position of the target audio data may be determined as the target audio data section. Finally, the target audio data interval may be extracted.
In this embodiment, the execution body may store the target audio data interval and the encoded video data into two files, respectively, and establish a mapping between the two files. In addition, the target audio data interval and the encoded video data may be stored in the same file.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for recording a video in this embodiment represents the operation performed after the instruction for stopping recording is detected. When the recording is stopped, the audio encoder is stopped playing the target audio data while the transmission of the video data to the video encoder is stopped. Thus, a synchronous stop of video encoding and audio playback is achieved. Therefore, the audio and video synchronization effect in the recording process of the dubbing music videos is further improved. In addition, the operation of audio and video data storage is highlighted. Therefore, the audio and video files can be generated, and subsequent playing, uploading and the like are facilitated.
