Detailed Description
Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.
With the rapid development of computer technology, live webcasting is rapidly developed as a new technology. The network live broadcast is mainly carried out by relying on live broadcast clients, and the live broadcast clients can be divided into anchor clients and watching clients according to different functions of the live broadcast clients. The anchor can record live video data at the anchor client by using the camera equipment and upload the live video data to the live broadcast server. The user can request the live video data from the live broadcast server at the viewing client and view the live video data.
In the prior art, live video data is usually recorded by calling a common camera device by an anchor client, the anchor client is mainly installed in an electronic device, and the camera device may be a camera integrated in the electronic device or an external device connected to the electronic device. The focus of live video data recorded by common camera equipment is fixed, the area in the focus of the focus position in each frame of image frame in the live video data is clearer, and the area outside the focus is relatively fuzzy. However, different watching users have different attention points to the pictures in the video data, and the attention points to the pictures of the same watching user at different times can be changed when watching the video data. If the focus of the picture is not in the in-focus area where the focus position is located, the viewing user may not see the picture content clearly, which may affect the viewing effect.
Therefore, in order to satisfy the watching requirements of different watching users and improve the watching effect of live broadcast data, the inventor provides the technical scheme of the application through a series of researches. The focal position of live video data acquired by light field camera acquisition equipment can be changed, so that a watching user side requests a live broadcasting server side and acquires the live video data corresponding to a watching request after receiving the watching request of a watching user; according to a focus setting request aiming at the live video data, a focus position can be included in the focus setting request; the live video data can be set according to the focus position, that is, the live video data after setting can be played. The method and the device achieve the purpose that the user sets the focus point according to the intention, meet the personalized requirements and improve the live broadcast effect.
The technical solution of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an embodiment of a live webcasting method provided in an embodiment of the present application, where the method may include the following steps:
101: a viewing request is received.
102: and requesting and acquiring the live broadcast video data corresponding to the watching request from a live broadcast server.
And the live broadcast video data is recorded by the anchor client by using the light field acquisition equipment and is sent to the live broadcast server.
The watching client can provide different live video data published by the anchor for the user, and as a possible implementation manner, prompt information of the live video data published by a plurality of anchors can be displayed on an interface of the watching client for the user to select. The viewing request may be generated upon detection of a user operation for any of the reminder information.
The light field acquisition equipment can completely record the sum of all light rays in any direction in a space, the acquisition equipment can acquire all light source information in a range, and the live broadcast video data is formed by the light source information acquired by the acquisition equipment. The focus of the collected light source information can be adjusted at will after collection, and 'shooting before focusing' is realized. In the embodiment of the invention, the live video data acquired by the light field acquisition equipment is full data, and the focus is not set in the full data and can be set during playing.
103: receiving a focus setting request for the live video data; wherein the focus setting request includes a focus position.
Optionally, a focus setting control may be set on a playing interface of the live video data, and when it is detected that the user triggers the focus setting control, the focus setting may be started.
As a possible implementation manner, a focus selection box may be prompted to the user, and the center of the focus selection box may be set as the focus position. When it is detected that the user drags the focus selection frame, the focus position is changed with the center of the focus selection frame. And after the selection frame stops moving, the final position of the selection frame is the selected focal position.
104: and setting the live video data according to the focus position.
The live video data is actually composed of one frame by one frame of image frame, and setting the live video data may be setting each frame of image frame of the live video data.
Each of the image frames may be decoded from the live video data.
As still another embodiment, in order to make the display effect of the live video data more prominent, the setting the live video data according to the focus position may include:

and setting each frame of image frame according to the focus position, wherein the area within the first distance from the focus position is an in-focus area, and the other areas excluding the in-focus area are out-of-focus areas.
The arrangement of the in-focus area and the out-of-focus area may make the display contents of the focus set by the user more prominent. The in-focus area is an area where a target object is highlighted, for example, the face of a main character that can be highlighted, and the out-of-focus area is a blurred portion of "background blurring", for example, a table behind the main character can be blurred. As shown in fig. 4, the image frame 200 includes a focal point 201, a circular area 202 is an in-focus area, and other areas outside the circular area 202 are out-of-focus areas.
As still another embodiment, in order to make the display hierarchy of the live video data more distinct, the setting the live video data according to the focus position may include:
determining each frame of image frame of the live video data;

The light source information can be graded, the light source information display effects of different display layers are different, the higher the display layer is, the clearer the light source information display at the corresponding position is, and the lower the display layer is, the more fuzzy the light source information display is. For example, the light source information can be divided into 1-9 orders, the 9 orders being the clearest and the 1 order being the blurrier.
The light field acquisition equipment can completely record the sum of light rays in all arbitrary directions in the space so as to acquire light source information, and therefore, the live video data is composed of a large amount of light source information. The light source information of each image frame is the image information constituting each image frame, and the light source information of the image frame may include color information, light intensity information, light direction information, and the like of the image frame.
The hierarchy of the target object in each image frame may be set to a high level, and the background information in each image frame may be set to a low level.
As still another example, the display hierarchy of the light source information located in the in-focus area of one frame image frame may be set to a high order, and the display hierarchy of the light source information located in the out-focus area of one frame image frame may be set to a low order. Wherein the higher order may include a plurality of display hierarchies, and the lower order may include other display hierarchies besides the higher order. For example, the high order may include 6 to 9 orders and the low order may include 1 to 5 orders.
As a possible implementation manner, the light source information at different positions in each frame of image frame may be set to the same display level, for example, the display levels at different positions in the focus may be set to 8 levels at the same time.
Alternatively, it is also possible to set an in-focus region set according to a focus setting request of a user to a high order and an out-of-focus region to a low order. As shown in fig. 3, each square represents one pixel, where 300 is a focal point, a display hierarchy of the focal point may be set to 9 steps, display hierarchies of the in-focus area may be set to 8, 7, respectively, and light source hierarchies of the out-of-focus area 203 are set to 4, 5, 4, 3, respectively.
105: and playing the set live video data.
The live video data after being set is live video data which can be played normally, and therefore personalized attention setting of the live video data is achieved.
In the playing process of the live video data, the watching client can receive a focus setting request of a user at any time so as to set a corresponding focus according to the real-time setting of the user.
As a possible implementation manner, after receiving the focus setting request for the live video data, the focus setting request for the live video data may be received again, and the live video data may be reset.
In the embodiment of the invention, the live video data is acquired through the light field acquisition equipment, and the user can acquire the live video data through the watching client and then set the focus of the live video data according to the intention, so that the live video data can be normally played, thereby realizing the personalized setting of the focus of the live video data and improving the playing effect.
