Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. 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.
At present, in most video conferences, a server synthesizes a video uploaded by a client and a main video stream of the video conference into one video stream through encoding and decoding, and forwards the video stream to all the clients. Referring to a schematic diagram of a video conference shown in fig. 1, assuming that three clients ABC simultaneously perform a network video conference, when joining the conference, the clients and the server negotiate, and report information such as a decoding mode that can be supported by the client, a supported resolution and the like to the server, and then the video conference server performs coding, decoding and converging on video streams according to a negotiation result of each client, and then sends the synthesized streams to each client, so as to achieve the effect of the video conference. For example, when a client a initiates a video sharing request, the client a first uploads a video file to a server where a video conference is located through a network protocol, and when the client a initiates a video playing request after the uploading is finished, the server decodes the video file and merges with an original video conference stream to synthesize a stream, and then forwards the stream to each client, so that the client ABC receives a video conference stream with a shared video.
Therefore, when the client initiates a video sharing request, the shared video stream and the video conference stream are merged and sent for display, so that all delay reasons are based on the server, the response delay of the video conference of the client is increased, and the single-point bottleneck is increased. Based on this, the video data sharing method, the video data sharing device and the server provided by the embodiment of the invention can be applied to equipment which can realize human-computer interaction, such as a server, a computer, a mobile phone, a tablet computer and the like, and can be particularly suitable for a scene of a network video conference.
To facilitate understanding of the present embodiment, a detailed description will be given of a video data sharing method disclosed in the present embodiment.
Example 1
The embodiment provides a video data sharing method, which is applied to a server of a video conference, wherein video data in the server is uploaded to the server from a client to share a video, and video streams in the server are uploaded to the server from a plurality of clients participating in the video conference.
In this embodiment, if a user wants to participate in a video conference, the user can log in a client (the client can be a computer, a mobile phone, a tablet computer, or other device capable of performing human-computer interaction and connected with a server in a communication manner), and then upload a video stream of the user to the server through the client. And uploading the video data stored in the server by the client to share the video. The video data can be uploaded by clients participating in the conference or clients not participating in the conference; the video data can be uploaded before the video conference or during the video conference.
Based on the above description, referring to the flowchart of a video data sharing method shown in fig. 2, the video data sharing method includes the following steps:
step S202, receiving a video sharing request sent by a target client.
The target client may be a client that wants to acquire video data pre-stored by the server. In the process of carrying out the video conference, if a user wants to acquire video data pre-stored by a server, a video sharing request can be sent to the server through a client (namely a target client) of the user. After receiving a video sharing request sent by a target client, the server can share video data to the target client.
Step S204, hardware capability information and network capability information of the target client are obtained.
When the server video data is shared to the target client, since the server stores the video data and the plurality of video streams, the target client needs to play the merged video data and the plurality of video streams. To reduce server stress and also reduce latency of the target client, the merge operation may be performed at the target client.
For example, after receiving a video sharing request sent by a target client, the server needs to determine whether the target client can locally merge video data and a video stream. Therefore, the server needs to determine the hardware capability information and the network capability information of the target client. The hardware capability information refers to the hardware level of the target client, and if the hardware capability information meets the requirement, the target client can quickly and accurately carry out local merging operation. The network capacity information represents the network transmission speed of the server and the target client, and the target client needs to receive video data and a plurality of video streams because the merging operation needs to be performed locally at the target client, and receives more data than the merging operation performed at the server, so that stronger network capacity information is needed.
And step S206, if the hardware capability information and the network capability information both meet the preset requirements, sending the video data and the plurality of video streams to the target client so that the target client can play the video data and the plurality of video streams in a combined manner.
If the hardware capability information and the network capability information both meet the preset requirements, the server can judge that the target client has the capability of locally executing the merging operation, can send the video data and the plurality of video streams to the target client, and the target client carries out the merging operation and plays the merged video data and the plurality of video streams.
In the video data sharing method provided by the embodiment of the invention, the server sends the video data and the plurality of video streams to the target client which provides that the hardware capability information and the network capability information both meet the preset requirements, and the target client merges and plays the video data and the video streams. The target client with better hardware capability and network speed can obtain the video data and the video stream from the server before other clients, and the video data and the video stream are synthesized and played faster than other clients, so that the delay of the target client is reduced. The server can also send the video data and the video stream to a target client with better hardware capability and network speed before synthesizing the video data and the video stream, thereby reducing the coding and decoding pressure of the server.
Example 2
The embodiment provides another video data sharing method, which is implemented on the basis of the above embodiments; the present embodiment focuses on a specific implementation of sending video data and multiple video streams to a target client. As shown in fig. 3, a flow chart of another video data sharing method, the video data sharing method in this embodiment includes the following steps:
step S302, receiving a video sharing request sent by a target client.
Step S304, acquiring the hardware capability information and the network capability information of the target client.
In the implementation, WebRTC (Web Real-Time Communication) is used as a transmission protocol, and the WebRTC is cross-platform and has independent acquisition, coding, decoding and transmission components. And introduces a dynamic confluence mechanism: the target client end will report some information, and the server will judge the hardware capability and network capability of the target client end according to the information.
If the hardware capability and the network speed capability of a target client are good, the server sends the video data and the main video stream to the target client together, and the target client synthesizes the video data and the main video stream to achieve the effect of reducing the delay of the client and reduce the single-point bottleneck. If at least one of the hardware capability and the network capability of the target client is not good, the server synthesizes the video data and the main video stream, and forwards the synthesized video stream to the target client.
Referring to another schematic diagram of a video conference shown in fig. 4, in the client segment ABC, both the hardware capability and the network capability of the client a are better, and the server may send the video data and the video stream to the client a, perform local merging operation by the client a, and play the merged video data and video stream.
Step S306, if the hardware capability information of the target client side meets the preset range and the network capability information of the target client side meets the preset conditions, the video data and the plurality of video streams are sent to the target client side.
The hardware capacity information and the network capacity information both meet preset requirements, namely the hardware capacity information of the target client side meets a preset range, and the network capacity information of the target client side meets preset conditions.
The hardware capability information in the embodiment includes hardware information of the target client, an encoding and decoding mode of the target client and a resolution supported by the target client; the network capability information includes UDP (User datagram protocol) packets uploaded by the target client. The hardware information of the target client comprises CPU information of the target client and memory information of the target client.
The fact that the hardware capability information meets the preset range means that the server can make certain requirements on the hardware meeting the range and determine whether the target client meets the requirements, for example: the core number of a Central Processing Unit (CPU) of the target client conforms to a preset first range; the memory quantity of the target client side accords with a preset second range; the encoding and decoding mode of the target client side accords with a preset third range; and the resolution supported by the target client conforms to a preset fourth range.
The above example makes requirements on four parameters, that is, the number of cores of the CPU of the target client, the number of memories, the encoding and decoding manner, and the supported resolution, and only the target client whose four parameters all meet the requirements may be referred to as a target client whose hardware capability information meets a preset range.
Besides the hardware capability, the server determines whether the network capability information of the target client meets a preset condition, which can be performed by the following steps: determining the data transmission speed of the target client based on the UDP data packet uploaded by the target client; and if the data transmission speed meets the preset flow condition, the network capacity information of the target client side meets the preset condition.
And the server determines the network capability of the client according to the UDP data packet sent by the client. The UDP data contains the frame rate of the data negotiation and the frame rate of the actual transmission. The data negotiation means that a client sends a request to a server, the client declares the format and the limitation of data required to be taken by the request, and the server determines the returned data according to request header information. The server may calculate the network capabilities based on the frame rate negotiated and the frame rate actually sent. For example, the server calculates the traffic of the target client according to the frame rate included in the UDP packet, and determines the network capability of the target client according to the traffic condition.
It should be noted that, the method for determining the hardware capability and the network capability of the target client is not unique, and may be replaced with each other.
If the hardware capability information of the target client does not accord with the preset range and/or the network capability information of the target client does not accord with the preset condition, the server can combine the video data and the plurality of video streams into a shared video stream; and forwarding the shared video stream to the target client so that the target client plays the shared video stream.
As shown in fig. 4, if both the hardware capability and the network capability of the client a are good, the hardware capability and the network capability of the client B and the client C have certain problems. For the client A, the server can not synthesize all video conference streams of all participants ABC and can not synthesize a shared video stream D, the ABCD four-way stream is sent to the client, coding and decoding confluence is carried out at the client, and the server directly sends the stream to the client aiming at the client without carrying out confluence operation, so the client obtains the stream earlier than other clients, and the overall effect is better than the effect of confluence at the server due to good network conditions and strong client processing capacity (namely hardware capacity), thereby reducing delay and single-point bottleneck.
And for the client B and the client C, the server performs ABCD confluence and transmits the synthesized single-path stream to the client. If all clients ABC accessing the video conference have good network conditions and processing capacity, the server does not perform merging operation and is switched into a forwarding mode to directly forward the ABCD four-way stream to all the clients, and if at least 1 of the clients ABC accessing the video conference has poor network conditions or poor processing capacity, the server performs merging operation and forwarding operation, although the server also performs merging operation, the user experience of part of the clients can be improved, delay is reduced, and the single-point bottleneck is reduced.
In particular, the server may provide the following steps to merge the video data and the plurality of video streams into a shared video stream: decoding the video data to obtain target video data; decoding the video stream to obtain a target video stream; merging the target video data and the target video stream to obtain a target shared video stream; and encoding the target shared video stream to obtain a shared video stream.
In this embodiment, the video data and the video stream are both in a coded state, and therefore the server can decode the video data and the video stream to obtain the target video data and the target video stream respectively. And the server then merges the target video data and the target video stream to obtain a target shared video stream, encodes the target shared video stream to obtain a shared video stream, and forwards the shared video stream to the target client.
The method provided by the embodiment increases the way of video stream confluence in the video conference, reduces the influence degree of the server performance on the client delay, and can utilize the hardware networks of all participants of the video conference to the maximum extent.
It should be noted that the above method embodiments are all described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
