Video recording method and device, storage medium and video recording apparatus

Abstract

The application provides a video recording method and device, a storage medium and a video recording equipment. The video recording equipment continuously collects unit video data and unit audio data during recording, encodes the unit video data by using a preset video encoding format to obtain a unit video encoding file, and encodes the unit audio data by using a preset audio encoding format to obtain a unit audio encoding file. The unit video encoding file and the unit audio encoding file are continuously saved. Since the unit video encoding file and the unit audio encoding file are saved, there is no video data and audio data that has not been encoded, so the video recording equipment can directly encapsulate the saved unit video encoding file and unit audio encoding file in a preset encapsulation format to obtain a video file, thereby realizing video recording.

[0003] When a video recording device uses this method to record video, if it encounters an abnormal termination situation (such as the recording application crashing), the player cannot read the index information located in the header container of the video file, and therefore cannot find the encoded video data and audio data in the video file, causing the player to be unable to play (decode) the video file.

[0050] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0051] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0052] Video recording devices (such as surveillance equipment, mobile phones, and drones) use video container formats (such as MKV, AVI, and MP4) to directly encapsulate encoded video and audio data into video files.

[0053] In common MP4 video files (video files encapsulated using the MP4 video container format), the video data acquired during recording is encoded using H.264 encoding, and the recorded audio data is encoded using AAC encoding. The encoded video data is then encapsulated into the video track corresponding to the MP4 container format, and the encoded audio data is encapsulated into the audio track corresponding to the MP4 container format to obtain the video file.

[0054] A video file corresponding to the MP4 container format can include at least a moov box and an mdat box, which can also be referred to as a moov container and an mdat container, respectively. After the encoded video data and encoded audio data are encapsulated into the video track and audio track to form a video file, index information corresponding to the video file can be obtained. The index information is written into the moov box located at the beginning of the video file (in some embodiments, the moov box may also be located at the end of the video file), while the encoded video data encapsulated into the video track and the encoded audio data encapsulated into the audio track are saved into the mdat box. The encoded video data and encoded audio data saved in the mdat box need to be accessed through the index information. That is, the player (decoder) needs to read the index information corresponding to the video file in the moov box in order to play (decode) the encoded video data and encoded audio data saved in the mdat box, so that the player can play the video file.

[0055] During video recording, if an abnormal termination occurs (which can also be understood as the video recording application crashing unexpectedly), at the moment of abnormal termination, there is still unencoded video and audio data on the recording device. Because this unencoded video and audio data is not packaged into a video file at the time of abnormal termination, no index information corresponding to the video file is generated, and therefore no index information is written to the moov box located at the beginning of the video file. In this situation, the player (decoder) cannot read the index information in the moov box, and therefore cannot play (decode) the encoded video and audio data saved in the mdat box, resulting in the player being unable to play the video file.

[0056] To address the issue of unplayable video files, this application provides a video recording method. The method includes continuously acquiring unit video data and unit audio data during recording; encoding the unit video data using a preset video encoding format to obtain a unit video encoded file, and encoding the unit audio data using a preset audio encoding format to obtain a unit audio encoded file; continuously saving the unit video encoded files and the unit audio encoded files; and, in response to a packaging instruction, packaging the saved unit video encoded files and unit audio encoded files into a video file using a preset packaging format. This method can solve the aforementioned problem of unplayable video files.

[0057] Please see Figure 1 , Figure 1This is a schematic diagram of the system architecture of a video recording method provided in an embodiment of this application.

[0058] like Figure 1 As shown, the system architecture may include at least a video recording device 101, which is equipped with at least a camera, a microphone, and a local disk. The camera and microphone are used by the video recording device 101 to capture video and audio data during recording, respectively. After capturing the video and audio data, the video recording device 101 encodes the video and audio data using selected video encoding formats and saves the encoded video and audio data to the local disk. The video recording device 101 may include at least a camera, smartwatch, smartphone, tablet, laptop, or desktop computer.

[0059] In this embodiment, firstly, the video recording device 101 can continuously collect unit video data and unit audio data during the recording process; secondly, the unit video data is encoded using a preset video encoding format to obtain a unit video encoded file, and the unit audio data is encoded using a preset audio encoding format to obtain a unit audio encoded file; then, the unit video encoded file and the unit audio encoded file are continuously saved; finally, in response to a packaging instruction, the video recording device 101 packages each saved unit video encoded file and each unit audio encoded file into a video file using a preset packaging format.

[0060] In some embodiments, the system architecture may further include a network 102 and a cloud storage 103. The network 102 may be a medium for providing a communication link between the video recording device 101 and the cloud storage 103. The network 102 may include various types of wireless communication links, such as Bluetooth communication links, Wireless-Fidelity (Wi-Fi) communication links, or microwave communication links.

[0061] Specifically, the video recording device 101 can save the encoded video and audio data to the cloud storage 103 via the network 102, saving storage space on the local disk of the video recording device 101. The video recording device 101 can also access the cloud storage 103 via the network 102 to retrieve the encoded video and audio data saved in the cloud storage 103.

[0062] It should be understood that Figure 1 The number of video recording devices 101, network 102 and cloud storage 103 is only illustrative. Depending on actual needs, there can be any number of video recording devices 101, network 102 and cloud storage 103.

[0063] Based on the above system architecture, this application provides a video recording method.

[0064] Please see Figure 2 , Figure 2 This is a flowchart illustrating a video recording method provided in an embodiment of this application.

[0065] like Figure 2 As shown, video recording methods can include at least:

[0066] S202, The video recording device continuously collects unit video data and unit audio data during the recording process.

[0067] The following embodiments of this application will be described using the H264 encoding format corresponding to the MP4 container format for video data encoding and the AAC encoding format corresponding to the MP4 container format for audio data encoding as examples.

[0068] As video recording continues, video and audio data are continuously generated. The video data generated by the video recording device can be continuously encoded into H264 video data using a video encoder, and the audio data can be continuously encoded into AAC audio data using an audio encoder.

[0069] In this context, a unit of video data can be the amount of data that can be encoded into one frame of H.264 video data; a unit of audio data can be 1024 sampling points, with the video recording device encoding each 1024 sampling points into a unit of AAC audio data. In other words, when the video recording device acquires enough data to encode one frame of H.264 video data, it obtains a unit of video data; when the video recording device acquires 1024 sampling points, it obtains a unit of audio data.

[0070] It should be noted that using 1024 sampling points to encode AAC audio data is a common practice, but different numbers of sampling points can be used for encoding as needed, and this application does not limit this.

[0071] S204, The video recording device encodes the unit video data using a preset video encoding format to obtain a unit video encoded file, and encodes the unit audio data using a preset audio encoding format to obtain a unit audio encoded file.

[0072] As video recording continues, video and audio data are continuously generated. At the same time, the encoding of video and audio data is also ongoing, resulting in the continuous generation of H264 video data and AAC audio data.

[0073] Specifically, when acquiring unit video data, the video recording device encodes the unit video data using the H.264 encoding format to obtain unit H.264 video data. When acquiring unit audio data, the video recording device encodes the unit audio data using the AAC encoding format to obtain AAC audio data.

[0074] S206, the video recording device continuously saves the unit video encoded file and the unit audio encoded file.

[0075] The continuously generated units of H264 video data and units of AAC audio data are sequentially saved to local storage and / or cloud storage, so that the units of H264 video data and units of AAC audio data can be obtained at any time.

[0076] S208, the video recording device responds to the encapsulation command by encapsulating the saved individual video encoding files and individual audio encoding files into a video file using a preset encapsulation format.

[0077] Since the H264 video data and AAC audio data of each unit can be stored on a local disk or in a cloud storage, when the video recording device responds to the encapsulation command, it can directly access the local disk or cloud storage to read the H264 video data and AAC audio data of each unit. The H264 video data and AAC audio data are then encapsulated into a video file using a video encapsulation editor and the MP4 encapsulation format.

[0078] When the recording process terminates, the video recording device responds to the encapsulation command and directly encapsulates the saved H.264 video data and AAC audio data. Specifically, the video recording device can directly encapsulate each H.264 video data into the video track corresponding to the MP4 encapsulation format and each AAC audio data into the audio track corresponding to the MP4 encapsulation format. After obtaining the video file, the video file can generate complete index information, while the H.264 video data encapsulated into the video track and the AAC audio data encapsulated into the audio track are saved in the mdat box. When the player plays the video file, the player (decoder) directly reads the index information of the video file in the mdat box to find the H.264 video data and AAC audio data in the mdat box, and the player plays (decodes) the H.264 video data and AAC audio data to realize the playback of the video file.

[0079] Compared to related technologies, this application directly encapsulates the stored H.264 video data and AAC audio data of each unit, eliminating the possibility of unencoded video and audio data remaining in the video recording device when the recording process terminates. Therefore, this application can generate complete index information corresponding to the video file and save this index information to the moov box. Since the moov box in the video file header can store complete index information, the player (decoder) can read the index information in the moov box to find the encoded video and audio data saved in the mdat box, thus enabling playback of the video file.

[0080] Please see Figure 3 , Figure 3 This is a flowchart illustrating a video recording method provided in an embodiment of this application.

[0081] like Figure 3 As shown, video recording methods can include at least:

[0082] S302, the video recording device continuously collects unit video data and unit audio data during the recording process.

[0083] S304, the video recording device encodes the unit video data using a preset video encoding format to obtain a unit video encoded file, and encodes the unit audio data using a preset audio encoding format to obtain a unit audio encoded file.

[0084] S306, the video recording device continuously saves the unit's video encoded file and unit's audio encoded file.

[0085] For details regarding steps S302 to S306, please refer to the detailed descriptions in steps S202 to S206, which will not be repeated here.

[0086] In some embodiments, the video recording device needs to encapsulate the saved unit video encoded file and unit audio encoded file upon receiving an encapsulation instruction. The encapsulation instruction received by the video recording device varies depending on the termination condition of the recording process. The termination of the recording process can specifically include two cases: normal termination and abnormal termination. The following sections S308 to S310 describe how to generate an encapsulation instruction for the case of normal termination, and S312 to S314 describe how to generate an encapsulation instruction for the case of abnormal termination. Specifically:

[0087] S308, the video recording device receives a user operation to end recording.

[0088] Please see Figure 4 , Figure 4This illustration shows a video recording device receiving a user operation to end recording, as provided in an embodiment of this application. When the video recording device receives an operation from the recorder (also referred to as the user) pressing the "End Recording" button, the video recording process ends normally, which can also be understood as the recording of the required video being completed. It should be noted that the user's button operation can be pressing a physical button on the video recording device or touching a button on the recording application's display interface. In some embodiments, the video recording device may also be prompted to end recording via voice, or a gesture corresponding to the normal end of the video recording process; this application does not impose limitations on this.

[0089] When the video recording device receives a user's command to end recording, it needs to encode the last generated video and audio data during the recording process (it should be noted that the video recording device encodes and saves the video and audio data simultaneously with their generation; therefore, when the user's command to end recording is received, the last generated video and audio data during recording has not yet been encoded), and then save the encoded H264 video and AAC audio data. Since the video recording ends normally, what is saved is the complete and encoded H264 video and AAC audio data.

[0090] S310, the video recording device generates encapsulation instructions based on user operations used to end recording.

[0091] Taking the saving of unit H264 video data and unit AAC audio data to the local disk as an example, when the video recording device receives the encapsulation instruction, the video recording device directly accesses the local disk and reads the saved unit H264 video data and unit AAC audio data.

[0092] The video encapsulation editor encapsulates H264 video data into the video track corresponding to the MP4 encapsulation format, and encapsulates AAC audio data into the audio track corresponding to the MP4 encapsulation format, thus encapsulating the video and audio encoded files generated during video recording into a video file.

[0093] Since the local disk stores complete and encoded H.264 video data and AAC audio data when video recording ends normally, the video container editor can generate complete index information corresponding to the video file after containerization and write this index information into the moov box of the video file. The player (decoder) can then read the index information in the moov box to find the encoded video and audio data stored in the mdat box, thus enabling playback of the video file.

[0094] In some embodiments, video recording may terminate abnormally, meaning the recording is not intentionally stopped by the user. Examples include, but are not limited to, the video recording application crashing unexpectedly or the video recording device running out of battery. In the event of an abnormal termination of video recording, the process of generating encapsulation instructions includes steps S312 to S314:

[0095] S312, after an abnormal recording process ends, the video recording device receives a user operation to save the video file.

[0096] Please see Figures 5 to 6 , Figure 5 This is a schematic diagram of the display interface of a video recording device provided in an embodiment of this application; Figure 6 This is another schematic diagram of the display interface of a video recording device provided in this application embodiment. An abnormal termination of the recording process can be understood as the recording application crashing, or it could be due to other reasons causing the abnormal termination of the recording process. In the case of a crashing recording application, the recorder needs to wait for the recording application to restart.

[0097] When you restart the recording application, a pop-up window will automatically appear on the recording application's screen displaying "Video cannot be played" (see...). Figure 5 ) or "There are videos that were not saved properly" (see Figure 6 The system will display messages such as "The video recorded by the recorder could not be saved properly and cannot be played back." When a user receives the above message, they need to press the "Restore Save" button (or the "End Recording" button mentioned above).

[0098] S314, the video recording device generates encapsulation instructions based on user operations used to save video files.

[0099] When the recording application crashes, it saves one unit of H264 video data and one unit of AAC audio data on the local disk.

[0100] When the video recording device receives the encapsulation command, it directly accesses the local disk to read the saved unit H264 video data and unit AAC audio data. The video encapsulation editor encapsulates each unit of H264 video data into the video track corresponding to the MP4 encapsulation format, and encapsulates each unit of AAC audio data into the audio track corresponding to the MP4 encapsulation format, thus encapsulating the unit video encoded files and unit audio encoded files generated during the video recording process into a video file.

[0101] S316, the video recording device responds to the encapsulation command by encapsulating the saved individual video encoded files and individual audio encoded files into a video file using a preset encapsulation format.

[0102] Since each unit of H264 video data and each unit of AAC audio data is stored on a local disk or cloud storage, when the video recording device responds to the encapsulation command, it can directly access the local disk or cloud storage to read the stored H264 video data and each AAC audio data. This allows the H264 video data and AAC audio data to be encapsulated into a video file using a video encapsulation editor and the MP4 encapsulation format.

[0103] Optionally, at the moment the recording application crashes, the final video data may not reach a full frame. This portion of video data cannot be encoded or saved. If recording one frame of video data takes 0.1 seconds, then recording unencoded video data may take tens of milliseconds. Simultaneously, the final audio data may not reach 1024 sampling points. This portion of audio data cannot be encoded or saved. If recording 1024 sampling points of audio data takes 0.1 seconds, then recording unencoded audio data may also take tens of milliseconds. Since unencoded and unsaved video and audio data cannot participate in encapsulation, the video file will lose tens of milliseconds of content containing unencoded and unsaved video and audio data.

[0104] S318, the video recording device generates file information based on the unit video encoding file and the unit audio encoding file.

[0105] S320, the video recording device writes file information into a preset container for the video file.

[0106] The video recording device generates file information based on the encapsulated video and audio data, and writes the file information into a preset container of the video file.

[0107] Specifically, since the local disk stores complete and encoded H.264 video data and AAC audio data, the video encapsulation editor generates complete index information corresponding to the video file after encapsulation and writes this index information into the video file's moov box. The player (decoder) can then read the index information in the moov box to locate the video and audio data stored in the mdat box, enabling playback of the video file. It should be noted that even if the recording application crashes momentarily, the unencoded video and audio data present will not participate in the encapsulation process and will not affect the encapsulation of the video file. The encapsulated video file will still generate complete index information corresponding to the video file and write this information into the moov box. Therefore, unencoded video and audio data will not affect the normal playback of the video file.

[0108] Please see Figure 7 , Figure 7 This is a flowchart illustrating a video recording method provided in an embodiment of this application.

[0109] like Figure 7 As shown, video recording methods can include at least:

[0110] S702, the video recording device continuously collects unit video data and unit audio data during the recording process.

[0111] S704, the video recording device encodes unit video data using a preset video encoding format to obtain a unit video encoded file, and encodes unit audio data using a preset audio encoding format to obtain a unit audio encoded file.

[0112] For details regarding steps S702 to S704, please refer to the detailed descriptions in steps S202 to S204, which will not be repeated here.

[0113] S706, the video recording device continuously saves the unit video encoded file and the unit audio encoded file to local storage and / or cloud storage, respectively.

[0114] The video recording device continuously saves the unit video encoded file to a video folder named with a unique identifier, and continuously saves the unit audio encoded file to an audio folder named with the unique identifier; the video folder and the audio folder are located in local storage and / or cloud storage.

[0115] Specifically, when a user presses the start recording button on the video recording device, the video recording device begins recording video and creates a video folder and an audio folder on the local disk.

[0116] It should be noted that users can start video recording by pressing the physical button on the video recording device; in some embodiments, users can also start video recording by touching the start recording button displayed on the screen of the video recording device.

[0117] As video recording continues, H.264 video data and AAC audio data are continuously generated. H.264 video data is stored in hexadecimal format, and can be continuously saved to a designated video folder on the local disk using a corresponding file management tool. Similarly, AAC audio data can be continuously saved to a designated audio folder on the local disk using a corresponding file management tool. Each generated H.264 video and AAC audio data file can be saved separately to the designated video and audio folders on the local disk.

[0118] When a video recording device needs to encapsulate encoded video and audio data, it can directly access the local disk to read the encoded H264 video data and AAC audio data stored on the local disk. The local disk is located inside the video recording device, which can improve the speed at which the video recording device reads the encoded H264 video data and AAC audio data.

[0119] To facilitate the video recording device's access to the local disk and read the encoded H.264 video and AAC audio data stored there, the device can create video and audio folders on the local disk upon starting recording, naming each folder with a unique identifier. As recording progresses, video and audio data are continuously generated, and the device continuously generates encoded unit video and audio files. It continuously saves the encoded video files to the video folder named with the unique identifier, and the encoded audio files to the audio folder named with the same unique identifier.

[0120] Specifically, the video recording device generates unique identifiers for naming video and audio folders. These unique identifiers can be UUIDs (Universally Unique Identifiers), which are used to name the video and audio folders respectively. For example, if the UUID is 1e78091f-0988-406a-b8c6-700c0434d824, then the video folder could be named 1e78091f-0988-406a-b8c6-700c0434d824.h264, and the audio folder could be named 1e78091f-0988-406a-b8c6-700c0434d824.aac.

[0121] In some embodiments, the unique identifier may also be a timestamp, etc., as long as the uniqueness of the unique identifier is ensured, and this application does not impose any limitations.

[0122] In some embodiments, the video recording device can also save H.264 video data and AAC audio data to cloud storage, saving storage space on the local disk of the video recording device 101. Specifically, when the user activates the start recording button on the video recording device, a folder creation request is sent to the server, and the server creates video folders and audio folders in the cloud storage.

[0123] For each frame of H264 video data encoded, the video recording device can upload the encoded H264 video data frame to the video folder in the cloud storage; for each 1024 sample points of AAC audio data encoded, the video recording device can upload the encoded AAC audio data containing 1024 sample points to the audio folder in the cloud storage.

[0124] It should be noted that the storage location and storage method of the encoded H264 video data and AAC audio data can be set according to the actual situation, and this application does not limit them.

[0125] S708, in response to the encapsulation instruction, the video recording device obtains each unit video encoded file in the video folder named with the unique identifier, and obtains each unit audio encoded file in the audio folder named with the unique identifier.

[0126] Taking the unique identifier 1e78091f-0988-406a-b8c6-700c0434d824 as an example, the encapsulation instruction can contain the unique identifier 1e78091f-0988-406a-b8c6-700c0434d824. Based on the 1e78091f-0988-406a-b8c6-700c0434d824 contained in the encapsulation instruction, the unit video encoding file in the folder 1e78091f-0988-406a-b8c6-700c0434d824.h264 and the unit audio encoding file in the folder 1e78091f-0988-406a-b8c6-700c0434d824.aac can be read from the local disk.

[0127] S710, the video recording device encapsulates each of the unit video encoding files and each of the unit audio encoding files into a video file using a preset encapsulation format.

[0128] When the video recording device responds to the encapsulation command and synthesizes the video file (1e78091f-0988-406a-b8c6-700c0434d824.mp4), the video recording device can locate the folder 1e78091f-0988-406a-b8c6-700c0434d824.aac containing various H264 video data and the folder 1e78091f-0988-406a-b8c6-700c0434d824.h264 containing various AAC video data in its local storage, and then synthesize them.

[0129] The video recording device will encapsulate the read H264 video data and AAC video data into a 1e78091f-0988-406a-b8c6-700c0434d824.mp4 file using MP4 encapsulation format.

[0130] When the recording process terminates, the video recording device responds to the encapsulation command and directly encapsulates the saved H.264 video data and AAC audio data using the encapsulation method. Specifically, the video recording device can directly encapsulate the H.264 video data into the video track corresponding to the MP4 encapsulation format and the AAC audio data into the audio track corresponding to the MP4 encapsulation format. After obtaining the video file, the video file generates complete index information, while the encoded video data encapsulated into the video track and the encoded audio data encapsulated into the audio track are saved in the mdat box. When the player plays the video file, the player (decoder) directly reads the index information of the video file in the mdat box to find each video encoded file and each audio encoded file in the mdat box. The player then plays (decodes) each video encoded file and each audio encoded file, thus enabling the player to play the video file.

[0131] Compared to related technologies, this application directly encapsulates the stored H.264 video data and AAC audio data of each unit, eliminating the possibility of unencoded video and audio data remaining in the video recording device when the recording process terminates. Therefore, this application can generate complete index information corresponding to the video file and save this index information to the moov box. Since the moov box in the video file header can store complete index information, the player (decoder) can read the index information in the moov box to find the encoded video and audio data saved in the mdat box, thus enabling playback of the video file.

[0132] In some embodiments, video data is encoded in a preset video encoding format, and audio data is encoded in a preset audio data encoding format. The preset container format supports both the preset video encoding format and the preset audio data encoding format. Specifically, the above description of the embodiments of this application uses the H.264 encoding format corresponding to the MP4 container format for video data encoding and the AAC encoding format corresponding to the MP4 container format for audio data encoding as an example. It should be noted that the container format of the video file can also be other formats, as long as the container format of the video file supports the encoding formats of both the video data and the audio data. For example, when the video file uses the MP4 container format, the encoding format of the video data corresponding to the MP4 container format can also be AV1, VP8, and VP9, ​​etc., and the encoding format of the audio data corresponding to the MP4 container format can also be Opus and MP3, etc. When the video file uses the MOV container format, the encoding format of the video data corresponding to the MOV container format can also be MPEG-2, MPEG4-ASP (XVID), and H.264, etc., and the encoding format of the audio data corresponding to the MOV container format can also be PCM, MP3, and AAC, etc. In some embodiments, other video file container formats can also be used, and this application does not limit them.
