Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
First, An applicable scenario of the embodiment of the present application is explained, where the embodiment of the present application is applicable to a multi-user online video conference, a device that is shown in a current picture is referred to as a second device, which can be denoted by device B, and a source device of the current picture is referred to as a first device, where the default of the first device is multiple, which are denoted by a1, a2, …, An, and n is the number of the first devices. In this way, in the multi-person online video conference, the person of the second device may view the pictures of the n first devices, or may detail a user object corresponding to one of the first devices, and the one of the first devices may be referred to as a target first device. It should be noted that the first device and the second device have no major or minor components, and the above distinction is made for convenience of description and distinction.
Examples
Fig. 1 is a flowchart of a method for displaying a multi-person online video conference image according to an embodiment of the present invention, where the method may be performed by a system for displaying a multi-person online video conference image according to an embodiment of the present invention, and the apparatus may be implemented in software and/or hardware. Referring to fig. 1, the method may specifically include the following steps:
s101, each first device carries out first coding operation on the collected image data and sends the obtained first coded data to a second device for rendering.
Among them, JPEG (Joint Photographic Experts Group) is a picture coding format. Optionally, the first encoded data is JPEG encoded data. In addition, the format of the first encoded data can also be a proprietary protocol encoding format developed by the user.
Specifically, the first devices are respectively denoted by a1, a2, A3, a4, a5, a6, a7, A8, a9 and a10 by taking 10 as an example, and each first device continuously acquires user image data through a camera. In a specific example, the image data is color space format data, for example, the color space format data is YUV data, and the YUV data is a color space format when the data is collected by a camera. And then, each first device carries out first coding operation on the acquired image data and sends the acquired first coded data JPEG data to a second device for rendering.
S102, the second device detects the image frame to obtain the focus operation, determines that the first device corresponding to the image frame is the target first device, and sends a request for obtaining second coded data of the target first device to the cache server.
When a user of the second device wants to see a picture of a certain first device in detail, the user may move a mouse into an image frame of the first device, or click an image of the first device on a screen with a finger, during the operation, the image frame of the first device may acquire a focus, at this time, the second device detects an operation of acquiring the focus from the image frame, and determines that the first device corresponding to the first image frame is a target first device, for example, the target first device may be a 1. In a specific example, for example, a company headquarters offers various branches, each branch may view the pictures of the headquarters or other branches in detail.
Specifically, after the target first device is determined, the second device sends a request for acquiring the second encoded data of the target first device to the cache server. Optionally, the second encoded data is H264 encoded data, and the H264 encoding is a standard of a highly compressed digital video encoder. That is, in order to obtain a more smooth picture when viewed in detail, the second encoding operation may employ H264 encoding.
And S1031, if the cache server is receiving the second coded data of the target first device, the second device receives the second coded data forwarded by the cache server, and sends a request for stopping sending the first coded data to the cache server.
Specifically, after receiving the request of the second target device, the cache server determines the current data receiving state of the cache server. And if the cache server is receiving the second coded data of the target first equipment, the second equipment requests the cache server to stop sending the first coded data after receiving the second coded data forwarded by the cache server. In this way, a more detailed and smooth screen of the target first device can be seen in the display screen of the second device.
S1032, if the cache server does not receive the second coded data of the target first device, the cache server sends a second coded data request message to the target first device, the target first device carries out second coding on the acquired image data and sends the obtained second coded data to the cache server, and the cache server forwards the second coded data to the second device.
In addition, if the cache server does not receive the second encoded data of the target first device, the cache server sends a second encoded data request message to the target first device, that is, requests the target first device to send the second encoded data to the second device. At this time, the target first device performs second encoding on the acquired image data, for example, H264 encoding, and then sends second encoded data obtained by the second encoding to the cache server through an RTP (Real-time Transport Protocol), and the cache server sends the second encoded data to the second device.
S104, the second equipment decodes the second coded data, and renders the decoded image data into an image frame corresponding to the target first equipment for display.
In a specific example, the second device decodes the second encoded data from the target first device, and renders the decoded image data into the image frame corresponding to the target first device after the decoding is successful. Thus, the detailed and smoother screen of the target first device can be seen on the display screen of the second device.
Therefore, the problem that images of all devices cannot be displayed simultaneously in a real-time online video conference of more than one hundred people is solved, performance consumption of a GPU (graphics processing unit) of the devices is greatly reduced, and users corresponding to any devices can see images of users corresponding to other devices on a screen. When a user corresponding to one device needs to see the image of a user corresponding to one other device in detail or needs to see the image of the current speaker, the mouse can be moved into the image frame of the corresponding user, or the image frame of the corresponding user is clicked by a finger on the mobile terminal, so that a smoother picture can be displayed on the image frame of the corresponding user. The system is simple to operate, strong in experience, capable of greatly saving time for a user to use and capable of improving comfort.
Optionally, each first device performs a first encoding operation on the acquired image data to obtain first encoded data, and sends the first encoded data to the second device for rendering, which may specifically include: each first device collects image data and respectively carries out initial coding on the image data to obtain first coded data; each first device sends the first coded data to a cache server through a set transmission protocol; the cache server forwards the first coded data to the second equipment; the second device renders the first encoded data. Wherein, the transmission protocol is set to be RTP protocol.
Illustratively, the initial encoding of the image data includes: and extracting image data of a set frame number within a set time and carrying out initial coding. In a specific example, the set time may be 1 second, and the set frame number may be 2 frames, so that each first device extracts image data collected by 2 cameras within 1 second for initial encoding.
On the basis of the above technical solution, the technical solution of the present application further includes: and if the cache server receives a request that the target first equipment requests to stop sending the first coded data and/or the second coded data, stopping sending the data. If the cache server receives a request that the target first device requests to stop sending the first coded data and/or the second coded data, the first device is indicated to temporarily interrupt the conference or send the first coded data or the second coded data under other conditions, at this time, the cache server stops sending corresponding data to the second device.
On the basis of the above technical solution, the technical solution of the present application further includes: and if the second equipment detects that the image frame of the target first equipment loses the operation of the focus, sending a request for stopping the target first equipment from sending the second coded data and a request for continuously sending the first coded data to the cache server. If the user operates the mouse to remove the image frame of the target first device, or the finger clicks the image of the target first device on the screen again, the image frame is out of focus, at the moment, the second device detects that the image frame of the target first device is out of focus, at the moment, the second device sends a request for stopping the target first device from sending second coded data to the cache server, and then data sending is stopped; and the second equipment sends a request for continuously sending the first coded data to the cache server, and then continuously sends the first coded data, so that the second equipment can stop watching the detailed picture of the target first equipment and switch to a normal display picture.
On the basis of the above technical solution, the technical solution of the present application further includes: and if the cache server does not receive any second coded data of the second equipment requesting the target first equipment, sending a request for stopping sending the second coded data to the target first equipment. If the cache server does not receive any second coded data of the second device requesting the target first device, which indicates that the user does not want to view the detailed picture of any one of the image frames temporarily, a request for stopping the first coded data is sent to the target first device at the moment, and the target first device stops data transmission.
Therefore, the problem that images of all devices cannot be displayed simultaneously in a real-time online video conference of more than one hundred people is solved, performance consumption of a GPU (graphics processing unit) of the devices is greatly reduced, and users corresponding to any devices can see images of users corresponding to other devices on a screen. When a user corresponding to one device needs to see the image of a user corresponding to one other device in detail or needs to see the image of the current speaker, the mouse can be moved into the image frame of the corresponding user, or the image frame of the corresponding user is clicked by a finger on the mobile terminal, so that a smoother picture can be displayed on the image frame of the corresponding user. The system is simple to operate, strong in experience, capable of greatly saving time for a user to use and capable of improving comfort.
