Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic flow chart of a video data uploading method according to an embodiment of the present invention is shown, where the method includes:
s10, estimating the size of the video data to be uploaded by the camera device at this time; the uploaded video data is video data which is obtained by a camera device and forms a section of complete video file;
s11, sending a data uploading request to the video data storage equipment so that the video data storage equipment receives video data based on the data uploading request;
and S12, uploading the video data currently generated by the camera device to a video data storage device until the total volume of the video data uploaded this time meets the estimated size of the video data to be uploaded this time.
In this embodiment of the present invention, an execution main body of the video data uploading method may be a video data uploading device, and the video data uploading device may be a camera device (for example, a security monitoring camera device), or a data processing and uploading device connected to the camera device (for example, a host connected to the security monitoring camera device), and the like, which is not limited specifically herein.
In the embodiment of the present invention, it is understood that a complete video file may refer to a video file recorded according to a fixed video recording duration (for example, a complete video file uploaded and stored by an existing imaging device is a video file recorded according to 5 minutes), or may be a video file recorded according to a fixed file size (for example, the fixed file size is 5 Mb), and is not limited herein.
When the currently generated video data is uploaded, the uploaded video data may be a video data segment with a set data length or a single GOP, and the uploading is not particularly limited herein. Here, a GOP refers to a Group of pictures (Group of pictures), and refers to a Group of pictures consisting of one I frame and a plurality of P frames and a plurality of B frames.
The key problem to generate a video file by uploading video data is when the uploading is finished, so that a complete file can be formed. Therefore, it is necessary to estimate the size of the video data to be uploaded each time before uploading the video data that can constitute a complete video file.
In the embodiment of the invention, the size of the video data of a section of complete video file to be shot by the camera device is estimated in advance, and when the total amount of the video data uploaded by the camera device next meets the estimated size of the video data, the currently uploaded video data can form a complete video file, and the current video data uploading operation can be finished. From the above analysis, the embodiment of the invention can generate the video and upload the video at the same time, and does not occupy the memory of the camera equipment to cause the insufficient memory of the camera equipment with small memory, and does not need to configure the SD card of the camera equipment. Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
For example, if the data upload request includes information about the size of the video data to be uploaded, the step S12 includes:
s120, uploading the video data currently generated by the camera to a video data storage device until a video data uploading completion instruction sent by the video data storage device is received; the video data uploading completion instruction is as follows: the video data storage equipment judges that the total amount of the video data uploaded by the camera device at this time meets the size of the estimated video data at this time and issues the video data;
and S121, stopping uploading the video data according to the received video data uploading completion instruction.
In this embodiment, by adding the estimated size information of the to-be-uploaded video data to the data uploading request in advance, in the process of receiving the uploaded video data, the video data storage device may determine whether the video data uploaded by the current camera device may form a complete video file according to the size information of the to-be-uploaded video data analyzed from the request, and if the determination result is yes, issue the video data uploading completion instruction, thereby stopping uploading the video data of the current camera device.
It can be understood that the work of judging whether the uploaded video data can form a complete video file may also be performed by the video data uploading device.
In the foregoing embodiment, for example, the video data storage device is a server, the data upload request is an HTTP request, and the information of the size of the uploaded video data is written into a header statement of the HTTP request. It will be appreciated that the video data storage device may also be other devices, such as a computer or network video recorder that may be used to store video data.
Illustratively, as a first way of estimating the size of the video recording data according to the embodiment of the present invention, the step S10 includes:
and estimating the size of the video data to be uploaded of the camera device at this time according to the preset average code rate and the preset estimated video recording time.
For example, each piece of uploaded video data is a single GOP, and taking the example of uploading the video data to the cloud server, it is assumed that the cloud storage record is stored according to a fixed time duration, for example, the time duration of the cloud storage record generated by the timing record is 5 minutes, and the time duration of the cloud storage record triggered by the motion detection is 1 minute (the time duration of the cloud storage may be specified to other values, which is specified by the equipment manufacturer). Taking the cloud storage time length of 1 minute as an example, the size of a cloud storage video in one minute is estimated according to the average code rate, for example, the average code rate is 1Mbps, the video size in 1 minute is 1mbps 60s/8=7.5MB, and the size of the video data to be uploaded is stated to be 7.5MB in the uploaded http header content-length.
Further, the step S12 includes:
uploading the GOPs currently generated by the camera device to a video data storage device until the total data volume of all the uploaded GOPs meets the estimated size of the video data to be uploaded at this time; if the sum of the currently generated data of the last GOP to be uploaded at this time and the total data volume of all the GOPs uploaded at this time cannot meet the size of the estimated video data to be uploaded at this time, filling redundant data in front of the last uploaded GOP at this time, wherein the redundant data is discarded data during video playing.
In the process of uploading the video data, the GOPs may be uploaded one by one, that is: and uploading the currently generated GOP every time a GOP is generated, counting the data volume of the uploaded GOP while uploading in the GOP uploading process, and determining the last GOP to be uploaded when the estimated data residual volume of the size of the video data to be uploaded at this time is judged to be less than that of the two GOPs.
For example, in the above example, since there is a certain error between the estimated size of the video data to be uploaded and the size of the video data actually uploaded according to the average bitrate estimation, see fig. 2, the redundant data can be padded before the last GOP (invalid data does not affect decoding, and the player discards the video data when playing it), so that the actually generated size is equal to the previously stated size of 7.5MB. The number of GOPs of this scheme is variable, because the GOP size is not fixed, which is related to the complexity of the picture, the GOP of the picture with large complexity is larger, so that 7.5MB of data can be put down for less GOPs, the duration of a GOP is fixed, for example, 2 seconds or 4 seconds, and the size of each GOP is variable, so that 7.5M of data can be put down for variable number of GOPs. Therefore, the size of the video file is fixed, and the video recording duration is not fixed.
It is to be understood that the redundant data may be automatically added by the image pickup apparatus when it is determined that the above condition is satisfied, or may be automatically added by the recorded-video-data uploading device when it is determined that the above condition is satisfied. The redundant data can be zero data, and the corresponding decoding end is invalid data, so that the redundant data can be discarded during decoding, and the decoding of the video data is not influenced.
As another example, that is, as a second way of estimating the size of the recorded video data according to the embodiment of the present invention, the step S10 includes:
estimating the data size of a single GOP according to a preset code rate upper limit, a preset time length of the single GOP and a preset data redundancy coefficient of the single GOP; the data redundancy coefficient is greater than 1;
estimating the number of GOPs according to the preset actual video recording time length and the preset time length of a single GOP;
and predicting the size of the video data to be uploaded at this time of the camera device according to the predicted data size of the single GOP and the predicted number of the GOPs.
Further, the uploading the video data currently generated by the camera device to a video data storage device until the total amount of the video data uploaded this time meets the estimated size of the video data to be uploaded this time includes:
if the data size of the GOP currently generated by the camera device is equal to the estimated data size of the single GOP, uploading the GOP currently generated by the camera device to a video data storage device, and if the data size of the GOP currently generated by the camera device is smaller than the estimated data size of the single GOP, filling redundant data in the GOP currently generated and uploading the data of the GOP currently generated and the redundant data together as the single GOP to the video data storage device until the total data volume of all the GOPs uploaded at this time meets the estimated size of the video data to be uploaded at this time; wherein the total data size of the current generated GOP data and the redundant data is equal to the data size of the estimated single GOP, and the redundant data is discarded data during video playing.
It is to be understood that the redundant data may be automatically added by the image pickup apparatus when it is judged that the above condition is satisfied, or may be automatically added by the recorded-video-data uploading device when it is judged that the above condition is satisfied. The redundant data can be zero data, and the corresponding decoding end is invalid data, and the redundant data can be discarded during decoding, so that the decoding of the video data is not influenced.
For example, each piece of uploaded video data is a single GOP, and taking uploading of the video data to a cloud server as an example, the maximum value of each GOP is estimated according to the bitrate upper limit, taking the bitrate upper limit of 1Mbps as an example (assuming 1 GOP every 2 seconds), and the size of 1 GOP is 1mbps × 2/8=250kb, by setting the data redundancy coefficient, a certain data margin can be allowed, and an instantaneous drastic increase in bitrate can be prevented, for example, the data redundancy coefficient can be set to 1.2, and the size of each GOP can be adjusted to 120% × 250kb =300kb. The total recording size is the number of GOPs multiplied by the maximum GOP value, and if the recording time requirement is 1 minute, 30 GOPs are required, that is, the total size is 9000KB. Referring to fig. 3, in this scheme, redundant data is filled in each GOP, and the recording duration and the recording size can be guaranteed to be fixed by controlling the number of GOPs.
In the two specific embodiments of video data estimation and uploading, the video data is estimated according to the two modes, and redundant data is added to the uploaded video data, so that while it can be ensured that all the video data which have been finally uploaded at this time can form a complete video file, the total amount of the video data which have been finally uploaded at this time can meet the estimated size of the video data to be uploaded at this time.
It should be noted that, in the two examples of video data prediction and uploading described above, if the time requirement is particularly strict and redundant data is allowed, the second option may be selected. The scheme can ensure the accuracy of time. If data size is a concern, it is undesirable to fill in too much redundant data, allowing for slight temporal fluctuations. Then option one may be selected. It will be appreciated that the two schemes are either possible or determined at the time of development.

From the above analysis, the embodiment of the present invention can generate and upload video while recording, and does not occupy the memory of the camera device, which results in insufficient memory of the camera device with small memory, and does not require the camera device to configure an SD card.
