The following describes an audio and video recording method, an apparatus, a computer device, and a storage medium in detail with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.
The application provides an audio and video recording method, the audio and video recording method can be applied to equipment with recording functions, such as a computer, a smart phone, a tablet personal computer, a recorder and the like, and the equipment can be provided with hardware, such as but not limited to an audio input module, a camera module, an image input module and the like, so that the recording function can be realized. It should be understood that the audio-video recording may be only recording audio, only recording video, or simultaneously recording audio and video, and the application is not limited specifically. Fig. 1 is a flowchart illustrating an audio and video recording method according to an exemplary embodiment of the present application. As shown in fig. 1, the audio and video recording method includes the following steps 101 to 102:
In this step, the path of the multimedia data may be a path in which the multimedia data is stored. Taking the example of recording audio and video by a computer, the multimedia data may be stored locally in the computer, and the storage path may be an address or a directory where the multimedia data is stored locally in the computer, for example, in a certain folder stored in a local disk, where the folder may be a folder designated by a user or a default folder set by a recording tool. The multimedia data may also be stored in an external device connected to the computer, such as a usb (universal Serial bus) flash disk, a mobile hard disk, and other external storage devices, and the storage path of the multimedia data may be the address where the multimedia data is stored in the external device. The multimedia data can also be stored in a server or a cloud data center, and the storage path of the multimedia data can be the address of the server or the cloud data center where the multimedia data is stored.
In one possible embodiment, the multimedia data may be audio, video, pictures, slides, etc., the audio may be inserted when only the audio is recorded or the audio and the video are recorded simultaneously, and the video, the pictures, the slides may be inserted when only the video is recorded or the video and the audio are recorded simultaneously. When recording audio and video, only one type of multimedia data can be inserted, and more than one type of multimedia data can be inserted. It should be understood that a segment of multimedia data may be inserted, or more than one segment of multimedia data may be inserted, and the specific type and amount of the multimedia data may be determined according to the audio/video editing requirement of the user, which is not specifically limited in the present application.
The start time of inserting the multimedia data into the recorded audio/video may refer to a start time stamp of the multimedia data in the recorded audio/video, the time stamp may include time, minutes and seconds, for example, 45 minutes and 30 seconds is 00:45:30, and the time stamp may further include microseconds. The starting time for inserting the multimedia data into the recorded audio and video can be set by the user according to the requirement of the user.
And step 102, in the current audio and video recording process, if the recording time reaches the starting time, replacing the audio and video data written into the recording channel with the multimedia data.
In this step, it can be understood that, in the process of recording audio and video, the recording device writes the acquired audio data and video data into the recording channel for recording, the audio data and video data are acquired in real time, the audio data and video data can be acquired through a microphone, a camera and the like, and the video data of screens of a computer, a mobile phone, a tablet computer and the like can also be acquired. The recording device can time the recorded audio and video and calculate the time length of the currently recorded audio and video, and because the recording device acquires the starting time of inserting the multimedia data into the recorded audio and video, when the timed recording time reaches the acquired starting time, the currently written audio and video data is replaced by the multimedia data acquired according to the storage path, so that the multimedia data is inserted into the currently recorded audio and video.
In the audio and video recording method of the above embodiment, the recording device may acquire a path of the multimedia data and a start time of inserting the multimedia data into the recorded audio and video, and replace the audio and video data currently written into the recording channel with the written multimedia data when the recording time of recording the audio and video reaches the acquired start time in the process of currently recording the audio and video. Therefore, when the user records the audio and video, the originally prepared multimedia data (such as audio, video, pictures, slides and the like) can be inserted into the recorded audio and video in real time, and after the recording is finished, the exported audio and video playing file comprises the inserted multimedia data. Therefore, a user can flexibly insert required multimedia data in the audio and video recording process, and the user does not need to wait until the audio and video recording is finished, and then insert the required multimedia data in the exported audio and video playing file by utilizing audio and video later-stage editing software, so that the method is convenient to operate, can greatly reduce the processing time, and effectively improves the audio and video recording efficiency.
In order to facilitate management of related information of multimedia data, in an exemplary embodiment of the present application, a path of the multimedia data and a start time of inserting the multimedia data into a recorded audio/video are stored in an index file. The related information of the multimedia data which needs to be inserted for recording the audio and video is stored and identified by establishing the index file, so that the recording equipment can quickly acquire the related information of the multimedia data, and the requirement of inserting the multimedia data into the recorded audio and video can be quickly responded.
In an exemplary embodiment of the present application, the index file may further include: and the duration of writing the multimedia data into the recording channel is used for describing the time length from the starting time to the ending time of inserting the multimedia data into the recorded audio and video. That is to say, the user may set the duration length of writing the multimedia data into the recorded audio/video, for example, the user may set the start time of inserting the multimedia data into the recorded audio/video to be 10 minutes and 30 seconds, and the duration to be 5 minutes, that is, the multimedia data starts to be written into the recording channel from 10 minutes and 30 seconds of recording the audio/video, and may last for 5 minutes, and when the recording time of recording the audio/video reaches 15 minutes and 30 seconds, the multimedia data may be stopped from being continuously written into the recording channel.
As an example, the multimedia data that the user needs to insert is a segment of audio or video, and only a part of the audio or video may be inserted according to the requirement, that is, the duration that the recorded audio and video data needs to be written may be identified by setting the duration, so that it may be avoided that all the multimedia data is written into the recorded audio and video data.
As another example, the multimedia data that the user needs to insert is a picture, and the duration can be set to ensure that the picture is continuously written into the recorded audio/video. It can be understood that the picture is written into the recorded audio and video, and each video frame is the same picture.
In another exemplary embodiment of the present application, the index file may further include a start time stamp and an end time stamp of the multimedia data that needs to be written to the recording channel. For example, the inserted multimedia data is a segment of audio or video, the user may choose to intercept a segment of the audio or video to write into the recording channel, where the segment may start and end at any time stamp of the audio or video, and start and end time stamps of the audio or video to be written, and when writing into the recording channel, the recording device may read the audio or video to be written according to the obtained start and end time stamps.
The storage of the related information of the multimedia data in the index file can be represented in various forms that can be accurately read by a computer. Taking an example of inserting a picture, the related information of the multimedia data stored in the index file can be represented as follows:
record_frame_subtitle 2020/03/27 14:00:00
png start time for writing class _ begin.png picture into recorded video
00:00:00,00:03:00
/data/pic/teacher/class_begin.png
Identification shows class _ begin.png picture at the beginning of recording video, duration is 3 minutes
00:40:00,00:40:30
/data/pic/teacher/class_end.png
Identification shows class _ end.png picture at 40 minutes of recording video, duration is 30 seconds
In order to improve the flexibility of audio and video recording, in an exemplary embodiment of the present application, the information of the path, the start time, the duration, and the like of the multimedia data may be read from the index file before starting audio and video recording or during the audio and video recording.
That is to say, before recording the audio and video, the user may add and create an index file to the relevant information such as the path, the start time, the duration and the like of the multimedia data to be inserted, so that the recording device obtains the resource of the multimedia data in advance, and when the recording time of recording the audio and video reaches the obtained start time, the data writing of the recording channel may be switched, and the multimedia data is inserted into the recorded audio and video.
In addition, the user can add relevant information such as a path, starting time, duration and the like of multimedia data to be inserted and establish an index file in the process of recording the audio and video so as to meet the requirement of the user on improvisation and improve the user experience.
It should be understood that, a user establishes an index file in the process of recording an audio/video to meet the requirement that multimedia data is inserted into the currently recorded audio/video, and the requirement may be that the multimedia data is inserted at a certain time after the recording time of the currently recorded audio/video, or that the multimedia data is inserted immediately at the recording time of the currently recorded audio/video.
In an exemplary embodiment of the present application, a user may set a starting time for inserting multimedia data in an index file, where the starting time may be any time after a recording time of a currently recorded audio/video, and it is understood that the starting time is greater than the current recording time and less than a time when the user plans to finish recording.
For example, when a teacher records a web class, when the current recording time is 20 th minute, it is conceivable that a small video of 5 minutes may be inserted and played after 5 minutes of the current recording time so that the time period serves as a time for providing a break between classes of students. Then, the teacher can fill in and establish an index file with information of a path, a start time, a duration and the like of the small video to be inserted in the process of recording the audio and video, the recording device reads the index file to obtain the small video to be inserted, inserts the small video into the currently recorded web lesson video at the 25 th minute according to the index file, and resumes writing in the currently acquired video data of the teacher's lecture at the 30 th minute after continuously playing for 5 minutes.
In another exemplary embodiment of the present application, the user may not set the start time for inserting the multimedia data, and thus, it may be considered that the user needs to insert the multimedia data at the current recording time, and then, when the recording device does not read the start time, the start time for inserting the multimedia data into the recorded audio/video is as follows: the time of the path to read the multimedia data from the index file. After the index file is read, the resource of the multimedia data is found immediately according to the path of the read multimedia data, and the read multimedia data is written into the recording channel instead.
In a possible implementation manner, when the index file read by the recording device does not include the start time, a prompt message is output, and the prompt message is used for prompting whether to immediately insert the multimedia data into the recorded audio/video. Therefore, the user can select whether the multimedia data needs to be inserted immediately or not through the prompt message, the requirement of the user is determined again, and if the determined instruction 'yes' of the user is received, the audio and video data written into the recording channel are replaced with the multimedia data immediately; if a negative instruction of 'no' is received from the user, a window or an interface for setting the start time is output to enable the user to refine the setting of the start time in the index file.
In order to facilitate a user to initiate a requirement for inserting multimedia data in a recording process, in an exemplary embodiment of the present application, a recording device may be provided with a service for automatically generating an index file, the user may initiate the requirement for inserting multimedia data by uploading the multimedia data to a designated address or directory, and the recording device may receive the designated address or directory multimedia data and input a path of the multimedia data to the index file based on a user instruction.
For example, the user instruction may be an instruction of "refreshing the index file", and when receiving the instruction, the recording device may automatically generate a new index file, where the file includes a path into which multimedia data for recording audio and video needs to be inserted. The recording device can read the index file and write the multimedia data into the recording channel in real time when reading the path information.
Fig. 2 is a flowchart illustrating a process of writing multimedia data into a recording channel according to an exemplary embodiment of the present application. As shown in fig. 2, the process of writing multimedia data into the recording channel specifically includes steps 202a to 202 b:
It can be understood that the multimedia data to be inserted into the recorded audio and video can be packaged in a specified multimedia packaging format and stored in a file form. In this step, the multimedia data can be transcoded into audio and video frame data with the same encoding parameters as the recorded audio and video based on the encoding parameters configured for the currently recorded audio and video, so that the multimedia data can be inserted into the currently recorded audio and video. The encoding parameters may be obtained from a configuration file of the recording device, and the encoding parameters may include, but are not limited to, at least one of the following parameters: audio coding format, video coding format, bitrate, frame rate, resolution, and the like. As an example, the recording and playing machine may input the encoding parameters and the multimedia data file by the encoding and decoding performance of its own bottom layer encoder, and start the bottom layer transcoder to transcode the multimedia data file into the same encoding format as the video source for recording the audio and video in real time, and write the multimedia data into the recording channel in units of frames.
When the multimedia data comprises video, pictures and slides, the multimedia data can be transcoded into video frame data. In one possible implementation, the video Frame data may be I Frame data (Intra-Frame, also called key Frame). For example, a user needs to insert a picture or a slide in a recorded video and audio, and the picture or slide can be transcoded into an I-frame data insertion. In another possible implementation, the video data may be I Frame data and P Frame data (Predictive-Frame). For example, a user needs to insert multiple pictures, multiple slides or a piece of video in recorded audio and video, and the multiple pictures or the slides or the piece of video can be transcoded into I frame data and P frame data according to a set ratio. As an example, the multimedia data is transcoded into video Frame data with a Frame rate of 25fps (Frame Per Second), and the video Frame data within one Second includes 1I Frame data and 24P Frame data, where the first Frame of the video Frame data is the I Frame data because the 24P Frame data needs to use the I Frame number as a coding reference, otherwise, when the audio-video export playing is recorded, the P Frame data lacking the I Frame data as a reference Frame is decoded, and a "screen splash" phenomenon may occur.
When the multimedia data includes audio, the audio data may be transcoded into audio frame data. In one possible embodiment, the Audio frame data may be data in an AAC (Advanced Audio Coding) encoding format. Step 202b, suspending writing the audio and video data into a recording channel, and writing the audio and video frame data into the recording channel.
In this step, the real-time collected audio/video data which is being written into the recording channel can be temporarily suspended and replaced by the transcoded audio/video frame data to be written into the recording channel. It is to be understood that the multimedia data can be inserted into a position corresponding to any time stamp in the recorded audio/video. For example, inserting videos, pictures and the like into the beginning of recording audios and videos can be used as a leader of recording audios and videos; for another example, inserting videos, pictures and the like into the end of recording the audio and video can be used as a trailer for recording the audio and video; for another example, the video, the picture, etc. are inserted between the beginning and the end of the recorded audio and video, and can be used as a midfield segment of the recorded audio and video.
When multimedia data is inserted into the beginning or between the beginning and the end of recording audio and video, after the writing of the multimedia data is completed, the audio and video data needs to be continuously written into the recording channel. It can be understood that when the multimedia data is written into the recording channel, the recording device can continue to collect the real-time audio and video data, but the writing of the audio and video data into the recording channel is suspended; and the acquisition of real-time audio and video data can also be suspended, and after the writing of the multimedia data is finished, the audio and video data can be continuously written into the recording channel, namely, the audio and video data acquired in real time are restored to be written into the recording channel again. Any combination of features of any of the above embodiments may be made as long as there are no conflicts or inconsistencies between the combinations of features, but are limited to the space and are not described one by one.
