Detailed Description
The present disclosure is described in further detail below with reference to the accompanying drawings and examples. 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.
It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
FIG. 1 illustrates a flow of one embodiment of a data storage method according to the present disclosure. The data storage method comprises the following steps:
In this embodiment, the execution subject of the data storage method may be an electronic device, such as an in-vehicle terminal device, an in-vehicle monitoring device, and the like. The execution main body can receive videos acquired by a plurality of image acquisition devices in communication connection in a wired connection mode or a wireless connection mode. Wherein one image capturing device typically captures one video. Multiple videos may be captured by multiple image capture devices.
It should be noted that the image capturing device may capture video as well as audio. If one or more image capturing devices are used to capture audio, the video received by the execution main body may include audio.
And 102, respectively compiling the received videos according to a preset compiling period to obtain data packets aiming at the videos.
The obtained data packet comprises the equipment identification corresponding to the image acquisition equipment and the video acquisition time corresponding to the video. Here, the device identification may be information for identifying the device. As an example, the device identifier may be 001, a, or a nail. The video capture time is generally information indicating the time at which the image capture device captures the video. As an example, the video capture time may be 20201221092012, which indicates that the image capture device captures video at 9 am, 20 min, 12 sec 12 m 12/21 st/12 th of 2020.
The coding cycle may be a preset value indicating a cycle length. As an example, the compiling period may be 1 minute, 2 minutes, or the like. It should be noted that if the compiling cycle is on the order of seconds, for example, the compiling cycle is 1 second, the required computing resources are increased, and the practical application value is usually not great. Therefore, in practice, to save computational resources, the compilation cycle is not usually set to the order of seconds.
In this embodiment, the execution body may process the video received in one coding cycle at a time by taking the coding cycle as a unit. For example, if the coding cycle is 1 second, the execution entity may start processing the video of one second at the end time of the one second. For example, the execution main body may process each video received within the 5 th second at the time when the 5 th second ends.
It should be noted that, since the captured video is usually continuous, the video capture time is usually referred to as the end time of each coding cycle. For example, if the coding cycle is 1 second, the execution entity may process each video received within the 5 th second at the time when the 5 th second ends, and at this time, it may consider that the video currently being processed has the video capture time of the 5 th second.
Here, the execution main body may respectively compile each video received in one compilation cycle to obtain a plurality of data packets corresponding to the compilation cycle, where each video in the compilation cycle may obtain one data packet. For example, for each video received in a coding cycle, the execution body may code the video as follows: the video, the equipment identification of the image acquisition equipment for acquiring the video and the video acquisition time of the video are directly combined into a data packet.
And 103, combining the obtained multiple data packets into a video file according to the equipment identification and the video acquisition time included in each data packet, and storing the video file.
In this embodiment, the execution main body may integrate videos whose video capturing times belong to the same compiling cycle into the same video file. In practice, video files are usually indexed by video capture time, and in the video files, data packets are usually distinguished by device identification. The method is beneficial to quickly finding the data packet to be searched from the video file, so that the video to be viewed is obtained.
In this embodiment, after obtaining the video file, the execution main body may store the video file. It should be noted that a video file can be integrated in one coding cycle.
According to the method provided by the embodiment of the disclosure, one video file is obtained by processing a plurality of videos acquired by each image acquisition device, and when data is written into the storage medium, only the video file needs to be written into at the same time, that is, only one path of data needs to be written into at the same time, which is beneficial to improving the data writing speed. In addition, the data loss caused by multi-path data writing can be avoided, and the stability and the reliability of data storage are improved.
In some optional implementation manners of this embodiment, the compiling the received multiple videos to obtain data packets for the videos includes: aiming at a video in a plurality of received videos, combining and generating a packet header of a data packet according to the video acquisition time of the video and the equipment identification of image acquisition equipment for acquiring the video; using the video as the data packet of the data packet; and combining the obtained packet header and the obtained packet data to obtain a data packet for the video.
Here, the execution body may compile each video received in a compilation cycle to obtain a packet corresponding to the video. Specifically, for each video, the execution subject may first combine the video capture time of the video and the device identifier of the image capture device that captures the video to form a packet header of a data packet. As an example, if the video capture time of the video is 20201221092012, the device identification of the image capture device capturing the video is a. Then "a" may be used as one field of the packet header and "20201221092012" as another field of the packet header. Thus, the two obtained fields can be combined to obtain the header of the data packet. Then, the execution body may directly take the video as packet data of a packet. Finally, the combination of the packet header and the packet data is the data packet for the video.
The realization mode can conveniently and rapidly obtain the data packet aiming at each video, and is beneficial to improving the data processing efficiency.
In some optional implementation manners of this embodiment, the compiling the received multiple videos to obtain data packets for the videos includes: aiming at a video in a plurality of received videos, combining and generating a packet header of a data packet according to the video acquisition time of the video and the equipment identification of image acquisition equipment for acquiring the video; using the basic code stream corresponding to the video as the packet data of the data packet; and combining the obtained packet header and the packet data to obtain a data packet for the video.
Here, the execution body may obtain a packet for each video in another manner. Specifically, for each video, the execution subject may first combine the video capture time of the video and the device identifier of the image capture device that captures the video to form a packet header of a data packet. As an example, if the video capture time of the video is 20201221092012, the device identification of the image capture device capturing the video is a. Then "a" and "20201221092012" can be directly combined to obtain "a-20201221092012" and thus the packet header. Then, the execution body may use an Elementary Stream (ES) corresponding to the video as packet data of the packet. Finally, the combination of the packet header and the packet data is the data packet for the video. It should be noted that, the execution main body may adopt the existing technology or the technology in the future development to obtain the elementary stream corresponding to the video, which is not limited in this embodiment.
In this implementation, since the elementary stream corresponding to the video is data obtained by compressing the video, the data obtained by the compression is usually much smaller than the video itself. Therefore, the elementary stream corresponding to the video is used as the packet data of the data packet, and the size of the data packet corresponding to the video can be effectively reduced. Which contributes to saving storage space.
In an optional implementation manner of each embodiment of the present disclosure, the combining the obtained multiple data packets into one video file according to the device identifier and the video capture time included in each data packet includes: and generating file names according to the video acquisition time, using the obtained multiple data packets as file contents, and determining the combination of the file contents and the generated file names as a video file.
Here, since the captured video is generally continuous, the video capturing time generally refers to the end time of each coding cycle. Therefore, the video acquisition time of each video acquired in the same compiling period is the same.
In this implementation, the execution body may first create a video file. Then, a file name is generated for the video file. As an example, the execution subject may obtain a file name of a video file by: and directly taking the video acquisition time as the file name. Thereafter, the file content is assigned to the video file. Here, the execution body may directly use, as the file content, a packet corresponding to each video received in the compilation cycle. As an example, if 5 videos are received in the current coding cycle, 5 data packets may be obtained. At this time, the file content may have the above-mentioned 5 packets. And finally, combining the file content and the file name to obtain the video file.
The realization mode can realize that a plurality of videos collected by each image collecting device are integrated into the same video file. The obtained video file is named by taking video acquisition time as name, and in the video file, each data packet can be distinguished through equipment identification. The data packets to be searched can be quickly found from the video file, so that the video to be viewed is obtained.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a data storage method according to an embodiment of the disclosure. The data storage method comprises the following steps:
The obtained data packet comprises the equipment identification corresponding to the image acquisition equipment and the video acquisition time corresponding to the video.
In the present embodiment, the specific operations of steps 201-203 are substantially the same as the operations of steps 101-103 in the embodiment shown in fig. 1, and are not repeated herein.
Wherein the request information comprises any one or more of the following items: equipment identification and video acquisition time.
The first video playing request is generally information for requesting to play a video, and the first video playing request includes the request information.
In this embodiment, the execution main body may receive a first video playing request input by a user. After receiving the first video playing request, the execution main body may search for the data packet in which the request information is located from the plurality of currently stored video files. Thereby playing the video corresponding to the data packet. For example, if the packet data of the data packet is a video itself, the video is directly played. If the data packet of the data packet is the basic code stream of the video, the basic code stream is restored to the video for playing.
As an example, when the executing entity executes the step of searching for the data packet where the request information is located from the stored multiple video files, if the request information is the device identifier, the executing entity may search for the data packet where the device identifier is located from each currently stored video file, and may obtain multiple data packets. Therefore, the execution main body can play the videos corresponding to the data packets according to the sequence of the video acquisition time.
As another example, when the executing main body executes the step of searching for the data packet in which the request information is located from the stored multiple video files, if the request information is the device identifier and the video capture time, the executing main body may search for the video file in which the video capture time is located from the currently stored multiple video files, and then find out the data packet in which the device identifier is located from the searched video file, so as to obtain one data packet. Thus, the execution main body can directly play the video corresponding to the data packet.
In this embodiment, each data packet in the video file includes the device identifier and the video capture time, so that the execution main body can quickly and accurately find the data packet required by the user when receiving the video playing request of the user, and thus quickly and accurately play the video that the user wants to view. The video query speed and the video playing speed can be improved.
Referring further to fig. 3, fig. 3 is a schematic flow chart of a data storage method according to an embodiment of the present disclosure. The data storage method comprises the following steps:
The obtained data packet comprises the equipment identification corresponding to the image acquisition equipment and the video acquisition time corresponding to the video.
In the present embodiment, the specific operations of steps 301-303 are substantially the same as the operations of steps 101-103 in the embodiment shown in fig. 1, and are not described herein again.
Wherein, a window presents a video corresponding to the data packet under a device identifier. N is an integer greater than 1.
The second video playing request is generally information for requesting to play a video, and the second video playing request includes N device identifiers.
In this embodiment, the execution main body may receive a second video playing request input by the user. Upon receiving the second video playback request, the execution body may first create a number of windows equal to the device identification using existing or future-developed techniques. Then, for each device identifier, the execution main body may search for a data packet in which the device identifier is located from each currently stored video file to obtain a plurality of data packets, may select one window from the N created windows, and play a video corresponding to each data packet in the selected window according to the order of video acquisition time. For example, if the packet data of the data packet is a video itself, the video is directly played. If the data packet of the data packet is the basic code stream of the video, the basic code stream is restored to the video for playing.
In this embodiment, each data packet in the video file includes the device identifier and the video capture time, so that the execution main body can quickly and accurately find the data packet required by the user when receiving the video playing request of the user, and thus quickly and accurately play the video that the user wants to view. The video query speed and the video playing speed can be improved. In addition, in the present embodiment, if the user wants to view videos from a plurality of image capturing apparatuses at the same time, the user may input a second play request including a plurality of apparatus identifications to the execution main body. In this way, the execution main body can search the data packet where each device identifier is located for each device identifier at the same time, so that videos from different image acquisition devices are presented in different windows. The method is beneficial to realizing the synchronous playing of multiple paths of videos.
