Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The present disclosure provides a video data processing method applied to a first device, as shown in fig. 1, the method includes:
step S101: the first device determines N second devices for uploading the total video data in parallel, wherein N is a natural number.
Step S102: the first device sends at least part of data blocks in the total video data to an ith second device through a first communication link between the first device and the ith second device so as to send at least part of data blocks in the total video data to a video server through the ith second device, wherein i is an integer which is greater than or equal to 1 and less than or equal to N. That is, the first device sends at least part of data blocks in the total video data to be uploaded to the video server to the second device, and sends at least part of data blocks in the total video data to the video server through the second device.
Step S103: the first device sends at least part of data blocks in the total video data to the video server through a second communication link between the first device and the video server, wherein the video server can acquire the total video data based on the first device and the N second devices.
Therefore, the first equipment can send the total video data to be uploaded to the video server through the first equipment and the second equipment in parallel to the video server, namely, the first equipment can send the total video data to be uploaded to the video server in parallel by means of the second equipment, so that the problem that the video is not instant in uploading is avoided to the maximum extent, the physical limitation that the video data are uploaded by using a single line in the prior art is broken through, and a foundation is laid for ensuring smooth playing of the video.
In a specific example of the present disclosure, the uploading, by the first device, of the total video data to be uploaded to the second device, that is, the sending, by the first device, at least part of the data blocks in the total video data to the ith second device through the first communication link with the ith second device, so as to send at least part of the data blocks in the total video data to the video server through the ith second device specifically includes:
the first device sends the total video data to the ith second device through a first communication link between the first device and the ith second device, so that the total video data is sent to the video server through the ith second device. That is, the first device directly transmits the total video data to be uploaded to the video server to the second device, and transmits the total video data to the video server through the second device. In this way, by means of the N second devices, starting from multiple links (including the second communication link where the first device communicates with the video server, and the communication link where the ith second device communicates with the video server, that is, at least two communication links), the total video data to be uploaded to the video server is sent to the video server, so that the instantaneity of video uploading is maximally ensured, and especially for scenes with high real-time requirements, such as live scenes, smooth playing of videos can be maximally ensured. Moreover, the problem that the total video data cannot be effectively uploaded due to the fact that the second communication link between the first device and the video server is in a problem can be avoided to the greatest extent.
In a specific example of the disclosure, the first device may also directly upload the total video data to be uploaded to a video server, that is, the first device sends at least a part of data blocks in the total video data to the video server through a second communication link with the video server, and specifically includes: and the first equipment transmits the total video data to a video server through a second communication link between the first equipment and the video server.
Therefore, under the condition that the first device directly uploads the total video data to the video server, the data which needs to be uploaded to the video server can be uploaded in parallel by means of the second device, namely by means of a communication link between the second device and the video server, so that the instantaneity of video uploading is ensured, and especially for scenes with high real-time requirements, such as live scenes, smooth playing of videos can be ensured to the maximum extent.
In this example, the following two scenarios may be included:
scene one: the first device uploads the full amount of data to be uploaded to the video server, i.e., the total video data, directly to the video server. Correspondingly, the first device further sends a part of data blocks in the total video data to the ith second device, that is, the first device uploads the whole data, that is, the total video data, and the second device uploads the part of data blocks, so that under the condition that the video server receives the data uploaded by the first device, the data uploaded by the second device is supplemented, and thus the problem that the total video data cannot be effectively uploaded due to the problem of the second communication link between the first device and the video server is avoided to the greatest extent, and a foundation is laid for ensuring smooth playing of videos.
Scene two: the first device uploads the full data to be uploaded to the video server, namely the total video data to the video server directly, and correspondingly, the first device also sends the total video data to the ith second device, namely, the first device uploads the full data, namely the total video data, while the second device uploads the full data, namely, the data uploaded to the video server by the first device and the second device are the full data. Therefore, under the condition that the video server receives the data uploaded by the first device and is not instant, the data uploaded by the second device can be directly used as supplement, so that the problem that the total video data cannot be effectively uploaded due to the fact that the second communication link between the first device and the video server is in a problem is solved to the greatest extent, and a foundation is laid for ensuring smooth playing of videos.
It can be understood that, in a case where the data uploaded to the video server by the first device is full data, such as the case of the above scenario one or scenario two, a situation of data redundancy may occur on the video server side, and at this time, to avoid data redundancy, after receiving data blocks from a plurality of devices, such as the first device and the N second devices, the video server discards the redundant data blocks by using the data blocks in the total video data received for the first time, so as to effectively avoid data redundancy.
It should be noted that, in practical applications, whether block uploading is performed on the total video data uploaded to the video server side may be determined based on an actual communication link condition and a data size, for example, when block uploading is required, taking scene one or scene two as an example, at this time, before the first device uploads the total video data, the first device may divide the total video data into a plurality of data blocks, and upload the plurality of data blocks in parallel, or upload the plurality of data blocks sequentially, and the like. Or, the first device directly uploads the total video data to the video server without requiring block uploading.
For example, as shown in fig. 2, the device a (i.e., the first device) adds a video device sharing function in addition to the original video capturing and video uploading functions. For example, the a device shares the total video data to be uploaded to the video server to a plurality of second devices, such as the B device and the C device, which are in the vicinity of the a device, so that the total video data is uploaded to the video server in parallel by the B device and the C device in the vicinity of the a device. In this way, compared to the existing scheme shown in fig. 3, the example can upload video data based on the network lines of the a device, the B device, and the C device, indirectly extending the upload capability of the a device.
In this example, when the device a, the device B, and the device C upload data, the same data are uploaded, and all are total video data; in this case, the video server receives total video data of a plurality of devices, i.e., the a device, the B device, and the C device, at the same time. In this example, in order to avoid data redundancy, based on a processing manner of redundant data, the video server discards repeated data packets (i.e., data blocks) after receiving and using the fastest data packet (i.e., using the first received data block), so as to avoid redundant data occurring on the video server side.
Specifically, under the condition that the network bandwidths of the device a, the device B and the device C are sufficient, the fastest received data packet is selected by the video server by using a mode of uploading multiple pieces of data at the same time, so that the problem that the video uploading is not instant is avoided to the maximum extent. Here, for comparison with the subsequent schemes, in this example, the a device divides the uploaded total video data into a plurality of pieces including a packet 1, a packet 2, a packet 3, a packet 4, and a packet 5 (hereinafter, simply referred to as total video data), and based on this, the step of parallel multi-device redundancy transmission includes:
step 1, the device A sends the total video data (including a data packet 1, a data packet 2, a data packet 3, a data packet 4 and a data packet 5) to the device B, and the device B sends the received total video data to a video receiving server.
Step 2: the a device transmits the total video data (including the packet 1, the packet 2, the packet 3, the packet 4, and the packet 5) to the C device, and the C device transmits the received total video data to the video receiving server.
And step 3: the a device simultaneously transmits the total video data (including packet 1, packet 2, packet 3, packet 4, and packet 5) to the video receiving server.
Here, it should be noted that, in practical applications, the execution sequence of the three steps is not limited, for example, step 1 to step 3 may be performed synchronously; or, firstly executing the step 3, and then executing the step 1 and the step 2 in parallel; or, step 3 may be performed first, and then step 1 and step 2 are performed sequentially, which is not limited in the present disclosure.
As shown in fig. 2, after receiving the total amount of data, i.e., the total video data, the video receiving server transmits the total video data to the video processing server, and the total video data is processed by the video processing server and then displayed to the user for viewing. Here, the video receiving server and the video processing server may also be collectively referred to as a video server.
It should be further noted that, in the process of uploading the data packets by the devices, such as the device a, the device B, or the device C, at least two of the data packets 1 to 5 may be uploaded in parallel, and the data packets 1 to 5 may also be uploaded sequentially, which is not limited in this disclosure. Correspondingly, due to the uncertainty of the network communication condition, the order of the data packets received by the video receiving server may also be different, for example, the data packet 3 sent by the device a is received first, and at this time, if the data packet 3 sent by the device B or the device C is received again, the data packet is directly discarded; secondly, the data packet 1 and the data packet 2 sent by the device B are received, and at this time, if the data packet 1 and the data packet 2 sent by the device a or the device C are received again, the data packets are directly discarded; finally, the data packets 4 and 5 sent by the device C are received, and in the same way, if the data packets 4 and 5 sent by the device a or the device B are received again, the data packets are directly discarded. At this time, the video receiving server receives the full data, and sends the received full data, that is, the total video data to the video processing server for processing and then displaying to the user. The above is merely an exemplary illustration, in practical applications, the video receiving server may further send a complete data packet to the video processing server after receiving the complete data packet, so as to further improve the video processing efficiency, and the disclosure does not limit this.
In another example, the video receiving server receives the full amount of data sent by the B device, and at this time, the received data of the a device and the C device are directly discarded.
Therefore, data needing to be uploaded to the video server is uploaded in parallel effectively by other devices, such as the device B and the device C, namely by the communication link between the second device and the video server, so that the instantaneity of video uploading is ensured, and especially for scenes with high real-time requirements, such as live scenes, smooth playing of videos can be ensured to the maximum extent.
In a specific example of the disclosure, the first device may further perform blocking processing on total video data to be uploaded to the video server, and further upload the data blocks after the blocking processing to the video server via the second device. In particular, the amount of the solvent to be used,
the first equipment carries out blocking processing on the total video data to obtain N +1 data blocks;
correspondingly, the above first device sends at least part of data blocks in the total video data to an ith second device through a first communication link with the ith second device, so as to send at least part of data blocks in the total video data to a video server through the ith second device, and the method specifically includes:
the first device sends the ith data block in the N +1 data blocks to the ith second device through a first communication link between the first device and the ith second device, so that the ith data block is sent to a video server through the ith second device.
For example, the first device sends the 1 st data block to the 1 st second device, and uploads the 1 st data block to the video server via the 1 st second device, meanwhile, the first device sends the 2 nd data block to the 2 nd second device, and uploads the 2 nd data block to the video server via the 2 nd second device, and so on, and uploads the data blocks of the total video data to the video server via different second devices in parallel.
Therefore, by means of the first communication link between the second device and the video server, the total video data needing to be uploaded to the video server is uploaded in parallel, and the network communication capacity of the first device is indirectly expanded.
It can be understood that, in this example, the first device may directly upload the full amount of data to be uploaded to the video server, that is, the total video data, to the video server, and the second device uploads the partial data, that is, the received data block sent by the first device, so that, when the video server receives the data uploaded by the first device, the data is not instant, the data can be supplemented based on the data uploaded by the second device, so as to maximally avoid the problem that the total video data cannot be effectively uploaded due to a problem occurring in the second communication link between the first device and the video server, and lay a foundation for ensuring smooth playing of the video.
It can be understood that, under the condition that the data uploaded to the video server by the first device is full data, data redundancy may occur at the video server side, and at this time, to avoid data redundancy, after receiving data blocks from the first device and the N second devices, the video server discards redundant data blocks by using the data block in the total video data received for the first time, so as to effectively avoid data redundancy.
In a specific example of the disclosure, the first device may further upload a partial data block in the total video data, for example, after the first device performs block processing on the total video data and obtains N +1 data blocks, at this time, the first device uploads one of the N +1 data blocks, specifically,
the sending, by the first device, at least part of the data blocks in the total video data to the video server through the second communication link with the video server specifically includes:
and the first equipment sends the (N + 1) th data block in the (N + 1) th data block to total video data through a second communication link with the video server.
That is, the first device uploads a part of data blocks in the total video data, and the second device uploads other data blocks in the total video data, so as to ensure that the video server can receive the full amount of data; meanwhile, the total video data to be uploaded to the video server can be sent to the video server in parallel by the aid of the N second devices from multiple links (including a second communication link for communicating the first device with the video server and a communication link for communicating the ith second device with the video server, namely at least two communication links), so that the instantaneity of uploading the video is guaranteed to the maximum extent, and especially for scenes with high real-time requirements, such as live scenes, smooth playing of the video can be guaranteed to the maximum extent.
In a specific example of the disclosure, the N +1 data blocks are different data blocks. Therefore, invalid transmission is avoided, the problem that the video is not uploaded immediately is avoided to the greatest extent, and a foundation is laid for ensuring smooth playing of the video.
In a specific example of the disclosure, the above-mentioned first device performs block processing on the total video data to obtain N +1 data blocks, specifically including: and under the condition that a second communication link between the first device and the video server is in a preset state, for example, under the condition that the network bandwidth of the second communication link is lower than a bandwidth threshold, performing block processing on the total video data to obtain N +1 data blocks. That is, the first device may determine whether the blocking process is required based on the network condition of the first device, and then upload the data blocks after the blocking process to the video server side in parallel by the second device.
For example, as shown in fig. 4, the device a (i.e., the first device) adds a video device sharing function in addition to the original video capturing and video uploading function. For example, the device a divides the total video data to be uploaded to the video server into blocks, and shares the blocks to a plurality of second devices, such as device B and device C, located near the device a, so that different blocks in the total video data are uploaded to the video server in parallel by the device B and device C near the device a. In this way, compared to the existing scheme shown in fig. 3, the example can upload video data based on the network lines of the a device, the B device, and the C device, indirectly extending the upload capability of the a device.
In this example, when the network bandwidth of each device, i.e., a device a, a device B, and a device C, is insufficient and cannot meet the data amount requirement, or the uploaded data amount is affected by the network bandwidth, each device performs data sharing, i.e., the device a, the device B, and the device C upload different data blocks in the total video data. In this example, the a device divides the total video data uploaded into a plurality of blocks including packet 1, packet 2, packet 3, packet 4, and packet 5, and based on this, the step of parallel multi-device block transmission includes:
step 1: the device A sends the data packet 2 and the data packet 5 to the device B, and the device B sends the received data packet 2 and the data packet 5 to the video receiving server.
Step 2: the device A sends the data packet 3 to the device C, and the device C sends the received data packet 3 to the video receiving server.
And step 3: the a device uploads the data packet 1 and the data packet 4 to the video receiving server.
Here, it should be noted that, in practical applications, the execution sequence of the three steps is not limited, for example, step 1 to step 3 may be performed synchronously; or, firstly executing the step 3, and then executing the step 1 and the step 2 in parallel; or, step 3 may be performed first, and then step 1 and step 2 are performed sequentially, which is not limited in the present disclosure.
It should be further noted that, in the process of uploading a data packet by each device, such as the device a or the device B, the data packet that needs to be uploaded by each device may be uploaded in parallel or sequentially, which is not limited in the present disclosure.
Correspondingly, due to the uncertainty of the network communication condition, the order of the data packets received by the video receiving server may also be different, for example, the data packet 1 and the data packet 4 sent by the device a are received first, and then the data packet 3 sent by the device C is received; and finally, receiving the data packets 2 and 5 sent by the B device, wherein at the moment, the video receiving server receives the full data, and sends the received full data, namely the total video data to the video processing server for processing and then displaying to the user.
As shown in fig. 4, after receiving the total data, that is, the total video data, the video receiving server sends the total video data to the video processing server, and then the total video data is processed by the video processing server and displayed to the user for watching. Here, the video receiving server and the video processing server may also be collectively referred to as a video server. The example is merely an exemplary illustration, in practical applications, the video receiving server may further send a complete data packet to the video processing server after receiving the complete data packet, so as to further improve the video processing efficiency, and the disclosure is not limited thereto.
Therefore, the total video data which needs to be uploaded to the video server is uploaded in parallel effectively by other devices, such as the device B and the device C, namely by the communication link between the second device and the video server, so that the instantaneity of video uploading is ensured, and especially for scenes which are insufficient in network bandwidth but have high real-time requirements, such as live scenes, smooth playing of videos can be ensured to the maximum extent.
In a specific example of the disclosure, the second device may be selected in a manner that, for example, the first device performs a device search within a preset range, and a device that is searched and can establish a link is used as the second device for uploading the total video data in parallel. Therefore, at least part of data in the total video data to be uploaded can be rapidly sent to the second device, and then the total video data to be uploaded to the video server is uploaded in parallel by means of the communication link of the second device and the video server, so that a foundation is laid for effectively avoiding the situation that the data cannot be uploaded immediately.
Here, considering that the second device is a device within a preset range of the first device, compared with the distance from the video server, the first device can quickly transmit the data to be uploaded to the second device, in other words, the second device can more quickly and stably acquire the data to be uploaded by the first device, and further, the communication capability of the first device is indirectly expanded by means of a communication link between the second device and the video server, so that a solution is provided for effectively avoiding that the data cannot be uploaded immediately.
In a specific example of the disclosed aspect, the first communication link is a bluetooth link; and/or the second communication link is at least one of the following links: mobile communication links, Wi-Fi (wireless network communication technology) links, optical fiber links. Here, the communication link between each second device and the video server may also be at least one of: a mobile communication link, a Wi-Fi (Wireless Fidelity) link, a fiber optic link.
For example, the first device may upload the total video data to be uploaded, or a partial data block in the total video data, to the second device based on the bluetooth link. Correspondingly, the first equipment uploads the data to be uploaded to the video server through the mobile communication network and the second equipment through the Wi-Fi link in parallel.
