Referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of an audio/video storage method according to the present application.
While the embodiments of the present application provide an embodiment of an audio-video storage method, it should be noted that, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown or described here.
The audio and video storage method comprises the following steps:
step S10, sending the coding parameters of the audio and video to the cloud, and returning the coding parameter numbers corresponding to the coding parameters of each path of code stream by the cloud;
the application environment of the method provided in this embodiment is to be applied to an intelligent camera, and it should be noted that the method provided in this embodiment may also be applied to an intelligent terminal such as a smart phone or a tablet computer, and is not limited herein.
When the intelligent camera is started, the encoding parameters of all audio and video in the current intelligent camera are firstly reported to the cloud, and the encoding parameters comprise: bitrate (referring to the amount of data used by a video or audio file in a unit time), frame rate (a measure for measuring the number of frames displayed in a picture), sampling rate (the number of samples taken from a continuous signal and forming a discrete signal per second), packing format (i.e., video format such as MP4, AVI, MKV, FLV, WMA, etc.), picture scale (referring to the ratio of the width to the height of a video picture), and resolution (referring to the number of pixels in the width to the height of a video), etc. The intelligent video player comprises a plurality of intelligent cameras, a video server and a player, wherein each intelligent camera only generates and maintains a media parameter file at the cloud end, audio and video coding parameters are kept unchanged at most of time, storage capacity can be saved by sharing the audio and video coding parameters, the player is also facilitated to connect two streams after the parameters are changed, and a mode of covering recording is adopted.
When the cloud receives the audio and video coding parameters reported by the intelligent camera, reading a media parameter file prestored in the cloud by the intelligent camera, traversing all the audio and video coding parameters reported by the camera, and judging whether the coding parameters exist in the media parameter file or not; if the audio/video coding parameter does not exist, writing the audio/video coding parameter reported by the camera into a media parameter file; if the audio and video coding parameter number exists, the audio and video coding parameter number in the media parameter file is returned. Further judging whether the encoding parameters which are not traversed exist at present, if so, returning to the step of judging whether the encoding parameters exist in the media parameter file; and if the code stream does not exist, returning the code parameter number of the code parameter of each path of code stream of the intelligent camera at the cloud.
Step S20, acquiring audio/video stream data, setting the coding parameter number and the time stamp information for each frame of audio/video stream data, and creating the index information of each frame of audio/video stream data according to the time stamp information;
acquiring audio and video stream data through an intelligent camera and a microphone, setting a coding parameter number and timestamp information for each frame of audio and video stream data, and creating index information of each frame of audio and video stream data according to the timestamp information; the time stamp information is the time sequence of acquiring the audio and video stream data. For example, for each frame of video in the video, the frame type and the timestamp of the current frame are acquired from the frame information of the current frame, the time offset of the current frame is determined according to the timestamp, the data of the part of the video located before the current frame is determined as the data offset of the current frame, and the frame type, the timestamp, the time offset and the data offset of the current frame are further combined into the index information of the current frame. Since the index information contained in each frame is different, the index information of each frame is independent.
Referring to fig. 5, the step of setting the coding parameter number and the timestamp information for each frame of audio/video stream data includes:
step S21, storing the acquired audio and video stream data into a queue based on the sequence of the timestamp information;
and step S22, setting the coding parameter number and the timestamp information for each frame of audio/video stream data in the queue.
The camera stores the acquired audio and video stream data into a queue based on the sequence of the time stamp information, sets a coding parameter number and time stamp information for each frame of audio and video stream data in the queue, and is used for switching code rate and playing in sequence according to the coding parameter and the time stamp when the subsequent audio and video stream is viewed; the frame is composed of different parts, usually the frame is composed of two parts of "frame head + data information", and the coding parameter number and the time stamp information are set at the position of the frame head of each frame.
Step S30, the index information is sent to the cloud end, and the cloud end returns the storage position and the file name of the audio and video stream data based on the index information;
the intelligent camera is provided with a limit value of audio and video data, when the audio and video data are accumulated to exceed the limit value or exceed the set time, index information is sent to the cloud, and the cloud returns the storage position and the file name of the audio and video stream data based on the index information. After receiving the index information, the cloud acquires contents in the index information, such as a frame type, a timestamp, a time offset, a data offset and the like, and determines a storage position and a file name of the current audio and video based on the contents, wherein the storage position is a C disk and the file name is a file A.
Referring to fig. 6, the step of sending the index information to the cloud includes:
step S31, dividing the audio/video file to be stored into a plurality of audio/video slice files, and creating index information corresponding to the plurality of audio/video slice files respectively;
and step S32, sending index information corresponding to the plurality of audio/video slice files to the cloud.
In order to accelerate the loading time before audio and video playing, the audio and video can be stored in the cloud in a slicing mode, under the condition of audio and video slicing processing, when the player plays the nth section of audio and video, the section of audio and video of N +1 can be pre-downloaded, so that playing is smoother, but the section of audio and video of N +2 cannot be downloaded by the player, so that bandwidth is saved for other users, and the pressure of a video server is reduced.
The intelligent camera divides the audio and video files to be stored into a plurality of audio and video slice files, creates index information corresponding to the plurality of audio and video slice files respectively, and sends the index information corresponding to the plurality of audio and video slice files respectively to the cloud. For example: and the intelligent camera divides the audio and video files to be stored according to a specified time interval, if the specified time interval is 8 seconds, the audio and video is divided every 8 seconds in the audio and video recording process. When the audio and video slices are divided, the index information of the audio and video slices can be set every time one audio and video slice is obtained.
The cloud end generates an uploading position and a slice file name of audio and video stream data according to the index information of the audio and video slice file, generates an index file corresponding to the slice, and writes the index information into the index file. Wherein, the index file can include: the information comprises the serial number of the camera, the file size of the audio and video file, the file name, the video recording starting time, the video recording ending time, the cloud storage address and the like. The index file is used for recording time points and key positions of key frames of streaming media audio and video, and can play a role in fast indexing when audio and video are played by equipment such as a mobile phone, a computer and the like. When the intelligent camera uploads a slice file of the monitoring video to the cloud storage server, I frame information needs to be written into a frame index file corresponding to the slice file. The cloud further judges whether the intelligent camera uploads audio and video data for the first time after being electrified, if so, the server end completes consistency check on the file related to the audio and video data of the camera uploaded to the cloud, and after the consistency check is completed, calculates the apend offset of the slice file and returns the uploading position, the slice file name and the apend offset of the audio and video data to the intelligent camera; if the audio and video stream data are not uploaded for the first time, the slice file apend offset is directly calculated, and the uploading position, the slice file name and the apend offset of the audio and video stream data are returned to the intelligent camera.
And step S40, the audio and video stream data are sent to the cloud according to the storage position and the file name, and the cloud stores the audio and video stream data.
When the intelligent camera acquires information such as a storage position, a slice file name and an ap pend offset returned by the cloud, the audio and video streaming data are uploaded to the cloud according to the acquired information and stored by the cloud. For example: and uploading the audio and video streaming data to a file A in the cloud C disk if the currently acquired storage position is the C disk and the file name is the file A. Further, after knowing the storage file name of the data, it is necessary to know the location of the data specifically stored in the file, referring to fig. 7, the step of sending the audio/video stream data to the cloud according to the storage location and the file name includes:
step S41, receiving the offset of the audio and video slice file sent by the cloud;
and step S42, determining the storage position of the audio and video stream data in the cloud corresponding file according to the offset, and sending the audio and video stream data to the storage position in the cloud corresponding file.
After receiving the offset of the audio and video slice file returned by the cloud, the intelligent camera determines the storage position of the audio and video stream data in the file corresponding to the cloud according to the offset, and sends the audio and video stream data to the storage position in the file corresponding to the cloud. The offset of the audio/video slice file refers to the number of bytes moved from a specified position forwards or backwards, the offset is used when used internal data is found from the file, the offset is generally divided into three types, one is to move a plurality of bytes backwards from the beginning of the file to find a target, the second is to move a plurality of bytes forwards from the end of the file to find the target, and the third is a relative position and is to move forwards or backwards from the current position of the file to find the target. When the intelligent camera uploads the audio and video stream data to a file, the offset needs to be known, the storage position of the audio and video stream data in the file is determined based on the offset, if a plurality of audio and video files are stored in the file A in a list form, the specific storage position of the current audio and video file to be stored is determined to be the tail end of the file list based on the offset, and the current audio and video stream data needs to be sent to the tail end of the list in the file A.
In the embodiment, the encoding parameter number corresponding to the encoding parameter of each code stream is returned by the cloud by sending the encoding parameter of the audio and video to the cloud; acquiring audio and video stream data, setting a coding parameter number and timestamp information for each frame of audio and video stream data, and creating index information of each frame of audio and video stream data according to the timestamp information; when the accumulated amount of the audio and video stream data exceeds a set threshold, sending index information to the cloud end, and returning the storage position and the file name of the audio and video stream data by the cloud end based on the index information; and uploading the audio and video streaming data to a cloud according to the storage position and the file name, and storing the audio and video streaming data by the cloud. The traditional three-in-one storage is divided into three independent parts for storage, and the corresponding mapping relation is established in the file, so that a user can take effect immediately when the uploading code rate is switched, and the real stream recording is realized without waiting for the start of the next file; the sequential reading and playing of the playing end can be realized, skip reading is avoided, the cloud storage reading efficiency is improved, and the playing speed is increased; retrieval information is independent and is used for retrieval operation independently, the retrieval operation is not required to be distinguished according to video resolution, and the retrieval efficiency is improved by centralized placement, so that the purpose of enhancing user experience is indirectly achieved.
Further, referring to fig. 3, a second embodiment of the audio/video storage method of the present application is proposed.
The second embodiment of the audio/video storage method is different from the first embodiment of the audio/video storage method in that before the step of sending the audio/video stream data to the cloud according to the storage location and the file name, the method further includes:
step S43, when the audio and video stream data is uploaded for the first time after being electrified, a flag bit is set in the index information;
and step S44, sending the index information carrying the flag bit to the cloud end, and carrying out data verification by the cloud end based on the flag bit.
Because the three-in-one storage is divided into three independent parts for storage, namely the encoding parameters, the encoding data and the index data are independently stored, the three parts can be out of synchronization after being stored in a power-off state. Therefore, when the intelligent camera is powered on and audio and video stream data is uploaded for the first time, a zone bit is preset, the zone bit is the starting-up zone bit information of the current intelligent camera, the zone bit is further placed in the index information, and when the index information is sent to the cloud, the zone bit can be sent to the cloud together. When the cloud acquires the zone bit, consistency check is carried out on the recording file and the index file stored by the intelligent camera, so that consistency of the monitoring video file, the index file and the parameter map stored on the cloud is guaranteed.
In this embodiment, consistency check is performed on each file through the flag bit, so that consistency of the monitoring video file, the index file and the parameter map stored in the cloud is ensured.
Further, referring to fig. 4, a third embodiment of the audio/video storage method of the present application is proposed.
The third embodiment of the audio/video storage method is different from the first and second embodiments of the audio/video storage method in that the step of sending the audio/video stream data to the cloud according to the storage location and the file name further includes:
step S45, the audio and video stream data are additionally sent to the existing file of the cloud according to the storage position and the file name; alternatively, the first and second electrodes may be,
and step S46, sending the audio and video stream data to the newly built file in the cloud according to the storage position and the file name.
When the current audio and video streaming data are collected, the intelligent camera judges whether a storage file needs to be newly built at the cloud end or not, if the current audio and video streaming data are new, the storage file needs to be newly built at the cloud end, and the current collected audio and video streaming data are uploaded to the new storage file. If the acquired audio and video stream data is to additionally upload existing data, a storage file does not need to be newly built at the cloud end, the intelligent camera writes new stream data after the uploaded file data by calling a cloud storage stream media file additional writing interface, the existing data can be deleted after the uploading is successful, if the uploading fails, the position of the file which needs to be added currently can be taken from the cloud storage, the additional writing is carried out again, and the original stream media file or data can be deleted as long as the additional writing is successful.
When the additional writing mode is adopted, a user can acquire the data which is uploaded in advance in real time or acquire a certain section of data according to the requirement, and the new data which is additionally uploaded cannot be influenced when the data is acquired. The user can flexibly decide whether to upload a new streaming media file or to add and write on the existing streaming media file according to the rule of the user, but not a fixed file uploading mode. The additional writing mode is added according to the recording time length required by each streaming media file, and when the recording time length contained in the streaming media reaches a certain value, a new streaming media file is created again to upload new audio and video stream data.
According to the embodiment, whether the acquired audio and video stream data is new data or not is judged, so that the uploading mode and the storage file of the stream data are determined, and when the stream data is uploaded in the additional writing mode, the new stream data is directly written in after the uploaded file data, so that the uploading efficiency of the stream data is improved.
In order to better explain the scheme of the embodiment of the application, the audio and video storage method comprises the following steps:

Further judging whether the encoding parameters which are not traversed exist at present, if so, returning to the step of judging whether the encoding parameters exist in the media parameter file; and if the code stream does not exist, returning the code parameter number of the code stream of each path of the camera at the cloud end from the server end. The camera collects audio and video stream data, a coding parameter number and time stamp information are placed for each frame of audio and video stream data, and index information is created for I frames of audio and video stream data according to the time stamp information. Judging whether the audio and video data of the camera head end is accumulated to exceed a limit value, if not, returning to the step of executing the camera to acquire audio and video stream data; if so, dividing the audio and video files to be stored into a plurality of audio and video slice files, determining index information corresponding to the plurality of audio and video slice files respectively, and uploading the index information of the audio and video slice files to a server side. And the server side generates an uploading position and a slice file name of the audio and video stream data according to the index information of the audio and video slice file, generates an index file corresponding to the slice, and writes the index information into the index file. Further judging whether the camera uploads audio and video data for the first time after being electrified, if so, completing consistency check on the camera audio and video data related files uploaded to the cloud end by the server end; and if not, calculating the slice file apend offset. And returning the uploading position, the slice file name and the apend offset of the audio and video streaming data to the camera for uploading the audio and video streaming data. After receiving data returned by the cloud, the camera determines the storage position of the audio and video stream data in the file according to the apend offset, and uploads the audio and video stream data to the storage position of the file corresponding to the cloud in an additional uploading mode.
