Detailed Description
In order to make the technical solutions of the present invention better understood, 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.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an aspect of the embodiments of the present invention, a data pushing method is provided, as an alternative implementation, the data pushing method may be applied, but not limited to, in an environment as shown in fig. 1.
According to an aspect of the embodiments of the present invention, a data pushing method is provided, and optionally, as an optional implementation manner, the data pushing method may be applied to, but is not limited to, a data pushing system in a hardware environment as shown in fig. 1. The data push system may include, but is not limited to, the terminal device 102, the network 104, the server 106, the database 108, and the terminal device 109. A target client (such as the live interface shown in fig. 1, which may be an anchor version client of a live platform) runs in the terminal device 102. The terminal device 102 includes a human-computer interaction screen, a processor and a memory. The man-machine interaction screen is used for displaying a live interface of the anchor client (such as the live interface of the anchor client shown in fig. 1); and the system is also used for providing a human-computer interaction interface to receive human-computer interaction operation for live network broadcast by a user by using live broadcast software. The processor is configured to generate an interaction instruction in response to the human-computer interaction operation, and send the interaction instruction to the server 106. The memory is used for storing related attribute data, such as interface special effect information of a live interface, different virtual gift information of a live platform and the like. The terminal device 109 also includes a human-computer interaction screen for displaying a live interface of the viewer client, a processor, and a memory.
The specific process comprises the following steps: in step S102, in the clients operating in the terminal device 102, when the first anchor client and the second anchor client are in a session connection state, a first picture pushed by the first anchor client and a second picture pushed by the second anchor client are obtained; then, step S104 is executed, and the terminal apparatus 102 transmits the screen data to the server 106 via the network 104. The server 106 executes the steps S106-S110 to perform mixed flow operation on the first picture and the second picture to obtain mixed flow operation; carrying out boundary compensation processing and rotation processing on the mixed flow picture to obtain a target picture with the resolution ratio of a target proportion; and carrying out data encapsulation on the target picture to obtain a live broadcast data packet. Then, as step S112, the server 106 pushes the live data packet to the terminal device 102 and the terminal device 109 through the network 104; finally, in step S114, the terminal device 102 decodes the live data packet and displays the live picture.
As another alternative, when the terminal device 102 has a relatively high computing processing capability, the steps S106 to S110 may also be performed by the terminal device 102. Here, this is an example, and this is not limited in this embodiment.
Optionally, in this embodiment, the terminal device may be a terminal device configured with a target client, and may include, but is not limited to, at least one of the following: mobile phones (such as Android phones, iOS phones, etc.), notebook computers, tablet computers, palm computers, MID (Mobile Internet Devices), PAD, desktop computers, smart televisions, etc. The target client may be a video client, an instant messaging client, a browser client, an educational client, etc. Such networks may include, but are not limited to: a wired network, a wireless network, wherein the wired network comprises: a local area network, a metropolitan area network, and a wide area network, the wireless network comprising: bluetooth, WIFI, and other networks that enable wireless communication. The server may be a single server, a server cluster composed of a plurality of servers, or a cloud server. The above is merely an example, and this is not limited in this embodiment.
As an alternative implementation, as shown in fig. 2, the data pushing method includes:
s202, under the condition that a first anchor client and a second anchor client are in a session connection state, acquiring a first picture pushed by the first anchor client and a second picture pushed by the second anchor client, wherein the resolution of the first picture is a first proportion, and the resolution of the second picture is a second proportion;
s204, carrying out boundary compensation processing and rotation processing on a mixed flow picture obtained by mixing the first picture and the second picture to obtain a target picture with a resolution ratio of a target proportion, wherein the target proportion is a display proportion meeting the playing condition of the playing client;
and S206, carrying out data encapsulation on the target picture to obtain a live broadcast data packet, and sending the live broadcast data packet.
Taking the interface shown in fig. 3 as an example, it can be understood that the live view is an interface displayed when a live view is performed by a main broadcast client applied to the terminal. The interface may be divided into four display areas, including a live zone 301: the system comprises a display screen, a display screen and a display screen, wherein the display screen is used for displaying a picture played to audience users by a main broadcast user in a live broadcast process; the interaction area 302: the system is used for displaying the interaction information of audience users; setting area 303: the control is used for displaying a control used for setting live broadcast parameters; search area 304: and the control is used for displaying the control used for acquiring the target picture. As shown in the live broadcast area 301, a mixed flow picture obtained by mixing the first picture and the second picture is displayed in this area.
It should be noted that, the above-mentioned situation that the first anchor client and the second anchor client are in the session connection state may be regarded as a "connecting to the wheat" interaction mode, that is, the anchor accounts originally located in different live broadcast rooms are operated through "connecting to the wheat" so that different anchor objects are simultaneously displayed in the same live broadcast room. The above-described case of the session connection state is explained with reference to fig. 4. As shown in fig. 4 (a) and (b), the screen display modes of two different anchor broadcasters when performing live broadcasting independently are respectively shown, where the area determined by the square frame is the live-broadcasting screen display area. In this embodiment, the picture proportions of anchor a and anchor B are the same when they are live broadcast separately. In the case where the anchor a and the anchor B are in the session connection state, as shown in (c) in fig. 4, the anchor a and the anchor B are simultaneously displayed in the live view display area, and the display ratio of the live view display area is also changed. It is observed that, when the live broadcast is switched from the one-person live broadcast to the multi-person live broadcast, "live broadcast" the display width of the live broadcast screen display area (i.e., the display width: the display height) increases. Therefore, when the live display mode is changed, the live picture scale is also changed accordingly. In the prior art, when a stream pulling end acquires live broadcast picture data packets with different widths and high proportions, decoding of live broadcast picture data can be realized only by resetting parameters of a decoder, and in the process of resetting the parameters of the decoder, pictures displayed by a client in live broadcast can be blocked.
Optionally, the first scale of the first picture and the second scale of the second picture may be the same or different, and in the embodiment shown in fig. 4, the first scale of the first picture and the second scale of the second picture are the same. The display scale of the different screens is not limited.
Alternatively, the mixing may be performed not only on two screens but also on a plurality of screens. That is to say, in this embodiment, there may be a plurality of anchor clients in the session connection state, and the mixed flow processing may be performed on a plurality of live frames corresponding to the live frames of the anchor clients to obtain the mixed flow frame.
The target ratio may or may not be the same as the first ratio of the first screen. For example, the target ratio may be set to be consistent with the first ratio of the first frame, and both the target ratio and the first ratio are fixed to be 1: 1. In another preferred mode, the target proportion may be determined as a proportion of pictures pushed when the one-man anchor is live.
It can be understood that, because the probability of the anchor user performing the single live broadcast is usually greater than the probability of performing the live broadcast, in an alternative embodiment, the live broadcast picture ratio of a single anchor client may be set as a target ratio, and in the live broadcast picture data push process, the picture data is encapsulated and pushed according to the single live broadcast picture ratio. When the live video data is acquired, the pull stream end (which may be an anchor client or a viewer client) decodes the live video data according to a target ratio by a built-in decoder. When the anchor client is switched to the session connection state, the resolution of the mixed flow picture which needs to be pushed and displayed is changed, namely, the mixed flow picture is subjected to picture compensation and rotation processing to obtain a target picture matched with a target proportion, and then the target picture is packaged and pushed. After the data packet including the target picture is obtained, the stream pulling end can directly decode the received live broadcast data packet and display the restored mixed-flow picture under the condition of avoiding resetting the decoder, and further the technical problem that the live broadcast picture is blocked due to the existing method is solved.
In the embodiment of the invention, under the condition that a first anchor client and a second anchor client are in a session connection state, a first picture pushed by the first anchor client and a second picture pushed by the second anchor client are obtained; carrying out boundary compensation processing and rotation processing on a mixed flow picture obtained by mixing the first picture and the second picture to obtain a target picture with a resolution ratio of a target proportion; carry out data package to the target picture and obtain live broadcast data package to send live broadcast data package, thereby carry out the preliminary treatment through treating the live broadcast data of propelling movement, the resolution ratio control that makes the live broadcast picture that includes in the live broadcast data of propelling movement be the target proportion, and then avoided the stream end of drawing to pass through the decoder of resetting in order to realize the decoding to the data of the live broadcast picture of different proportions, thereby the realization directly decodes the operation under the circumstances that keeps the original parameter setting of decoder, has promoted live broadcast display effect.
As an optional implementation manner, the performing boundary compensation processing and rotation processing on the mixed flow picture obtained by mixing the first picture and the second picture to obtain the target picture with the resolution being the target ratio includes:
s1, carrying out boundary compensation processing on the mixed flow picture according to the target proportion to obtain a reference picture;
and S2, rotating the reference picture according to the target angle to obtain the target picture.
The method described above will be described below with reference to fig. 4 and 5. Fig. 4 shows a display diagram of the mixed flow before and after the mixed flow is displayed at different clients. As shown in fig. 4 (a) and (b), when the anchor client performs single-person live broadcasting, the width-height ratio of the live broadcasting screen is 9:16, and when the mode is switched to the two-anchor "live broadcasting" mode, the width-height ratio of the mixed-flow screen is 1: 1. Fig. 5 shows a picture processing process diagram after the mixed flow operation. Fig. 5 (a) shows a mixed flow picture that has a width to height ratio of 1: 1. In the case of obtaining the mixed flow picture illustrated in (a) of fig. 5, first, the boundary compensation process is performed on the left and right sides of the picture, that is, the mixed flow picture is widened. It is understood that the widening may be performed by directly adding blank areas with a pixel value of 0 on both sides of the picture, or adding black areas with a pixel value of 256, and the specific form of widening is not limited herein. After the widening processing is performed on the diagram (a) in fig. 5, the diagram (b) in fig. 5 is obtained, wherein the width-to-height ratio of the reference picture after widening is 16: 9. The obtained reference picture is rotated by 90 °, so that the target picture shown in (c) of fig. 5 is obtained, and the width-to-height ratio of the target picture is 9: 16. At this point, a target picture adapted to the target proportion is obtained through compensation processing and rotation processing of the mixed flow picture.
According to the method in the embodiment of the application, the mixed flow picture is subjected to boundary compensation processing according to the target proportion to obtain a reference picture; the reference picture is rotated according to the target angle to obtain the processing mode of the target picture, so that the pushed picture proportion is consistent with the preset target proportion, the situation that a decoder is reset by a stream pulling end according to live broadcast data with changed picture proportion is avoided, and the technical problem that the live broadcast picture is blocked in the prior art is solved.
As an alternative, performing boundary compensation processing on the mixed-flow picture according to the target ratio to obtain the reference picture includes:
s1, determining a target boundary to be compensated based on the resolution of the mixed flow picture;
and S2, performing filling compensation on the compensation area corresponding to the target boundary according to the target proportion to obtain a reference picture.
The above method will be described with reference to fig. 4 and 5. As shown in fig. 4 (c), the ratio of the width to the height of the direct broadcast frame indicated by the resolution of the mixed-flow frame is 1:1, and when the preset target ratio is 9:16, it can be determined that the width of the frame to be compensated on the left and right sides of the mixed-flow frame illustrated in fig. 5 (a) is 7/18 of the mixed-flow frame width, that is, 7/18 of the mixed-flow frame width is required to be compensated on the left and right sides of the direct broadcast frame illustrated in fig. 4 (c), and the height of the compensated frame is consistent with the height of the mixed-flow frame. Further, the picture width-height ratio of the compensated reference picture is 16: 9.
By the method of the embodiment, the target boundary to be compensated is determined according to the resolution ratio based on the mixed flow picture; and filling and compensating the compensation area corresponding to the target boundary according to the target proportion to obtain a reference picture, so that the width-height proportion of the reference picture subjected to picture compensation is matched with the target proportion, and further the efficiency of picture data transmission and decoding is improved.
As an optional mode, the performing data encapsulation on the target picture to obtain a live data packet, and sending the live data packet includes:
s1, coding the target picture to obtain a coded data frame;
and S2, adding the boundary compensation parameters of the boundary compensation processing and the rotation parameters of the rotation processing to the frame tail of the encoded data frame, and performing data encapsulation to obtain a live broadcast data packet.
It can be understood that the operations of compensating and rotating the picture are all implemented in the data processing process, and the picture is not actually displayed on the client.
The operation of compensating the mixed flow picture can be specifically that pixel data is filled directly on the basis of the mixed flow picture data, and then picture data of a reference picture is obtained; the rotation operation is performed on the reference picture, specifically, the transposition operation is directly performed on the pixel matrix of the reference picture, so as to obtain the picture data of the target picture. The above operation may be any data processing method that can be used to achieve the above effects, and the specific manner is not limited herein.
On the basis of performing compensation operation and rotation operation on the mixed flow picture, corresponding operation parameters need to be added at the frame tail of the corresponding picture data frame. The boundary compensation parameters may include a picture width-height ratio indicated by the resolution of the target picture and a picture width-height ratio indicated by the resolution of the mixed-flow picture; the above rotation operation may include a rotation angle, and in the present embodiment, the above rotation operation is actually a rotation angle of 90 °, so 90 ° may be added as a rotation parameter to the corresponding frame end of the picture data frame. And finally, encapsulating the data frame added with the compensation parameter and the rotation parameter to obtain a live broadcast data packet.
By the embodiment of the application, the target picture is coded to obtain the coded data frame; the boundary compensation parameters of the boundary compensation processing and the rotation parameters of the rotation processing are added to the frame tail of the encoded data frame, and the live broadcast data packet is obtained by data encapsulation.
As an optional mode, before adding the boundary compensation parameter of the boundary compensation processing and the rotation parameter of the rotation processing to the end of the encoded data frame and performing data encapsulation to obtain the live broadcast data packet, the method further includes:
s1, determining the width and height of the compensation area during the boundary compensation processing as the boundary compensation parameters;
at S2, a rotation vector at the time of rotation processing is specified as a rotation parameter.
The above method is explained with reference to fig. 5. As shown in fig. 5 (a), assuming that the resolution of the mixed flow image indicates that the width of the mixed flow image is 180 pixels and the height of the mixed flow image is 180 pixels, in order to make the width-to-height ratio of the compensated reference image be 16:9, it is necessary to respectively compensate the compensation regions with the width of 70 pixels and the height of 180 pixels on the left and right sides of the mixed flow image, so that the width of the compensated reference image is 320 pixels and the height of 180 pixels, and further the image width-to-height ratio is controlled to be 16: 9. That is, in this embodiment, the width of 70 pixels and the height of 180 pixels of the compensation region are used as the boundary compensation parameters.
It is understood that after the reference picture is obtained, the rotation angle of 90 ° and the rotation direction (counterclockwise direction) are collectively used as the rotation parameters.
In another alternative embodiment, the boundary compensation parameter may also be a width-to-height ratio of the mixed flow picture before compensation of the mixed flow picture and a width-to-height ratio of the target picture after compensation.
By the method of the embodiment of the application, the target picture is coded to obtain a coded data frame; the boundary compensation parameters of the boundary compensation processing and the rotation parameters of the rotation processing are added to the frame tail of the encoded data frame, and the live broadcast data packet is obtained by data encapsulation.
As an alternative embodiment, in a case that the first anchor client and the second anchor client are not in a session connection state, it is determined that the first picture is played at the playing client according to the first ratio, and the rotation vector at the time of the rotation processing is determined to be zero.
It is understood that, in the case where the anchor client performs the one-man sole casting, as shown in (d) diagram and (e) diagram in fig. 5, since the ratio of the width to the height of the one-man sole casting is 9:16, which is a target ratio, the one-man sole casting can be directly decoded and displayed at the stream end. In order to indicate that the picture can be normally displayed without adjustment in the data frame, a boundary compensation parameter for indicating the proportion of the current picture and a rotation parameter of a rotation state can be added at the tail part of the data frame. For example, in the single-player mode, the target proportion and the picture proportion in the boundary compensation parameter added at the tail of the data frame are both 9:16, that is, the picture is indicated to be not compensated; while adding a rotation parameter of 0 deg., indicating that the picture is not rotated.
By applying the method in the embodiment, when the first anchor client and the second anchor client are not in a session connection state, it is determined that the first picture is played at the playing client according to the first proportion, and the rotation vector during rotation processing is determined to be zero, and the compensation parameter and the rotation parameter are also added to the picture data frame played by a single player alone, so that the formats of the data frames are kept consistent, and the stream pulling end can determine whether to perform reduction processing through specific data of the operation parameters, thereby improving the display efficiency of the live broadcast picture.
As an optional implementation, the method further includes:
s1, receiving a live broadcast data packet;
s2, analyzing the live broadcast data packet to obtain a live broadcast data frame of each frame;
s3, restoring the target picture according to the boundary compensation parameter and the rotation parameter to obtain a mixed flow picture;
and S4, displaying the mixed flow picture.
It will be appreciated that the above method may be applied to a pull end, which may be a viewer client or a cast client of other casts. Under the condition that the live broadcast data packet is obtained by the method, the mixed flow picture can be obtained by restoring the target picture by analyzing the boundary compensation parameter and the rotation parameter included in the data packet, so that the mixed flow picture can be directly displayed at the stream pulling end. For example, when the rotation parameter included in the current frame in the received data packet is 90 °, and the boundary compensation parameter includes 70 pixels in width and 180 pixels in height, the stream pulling end reversely rotates the acquired image data by 90 °, and cuts off the compensation regions of the 70 pixels in width and the 180 pixels in height on the left and right sides, so as to obtain the mixed-flow image capable of being directly played.
According to the embodiment of the application, the live broadcast data packet is received at the pull stream end; analyzing the live broadcast data packet to obtain a live broadcast data frame of each frame; reducing the target picture according to the boundary compensation parameter and the rotation parameter to obtain a mixed flow picture; and displaying the mixed flow picture, thereby realizing that the live broadcast picture in the data packet is displayed through the restoration operation under the condition of avoiding resetting the decoder, and improving the efficiency of displaying the live broadcast picture.

as shown in (d) and (e) of fig. 5, before data transmission of the single-person live picture, compensation parameters are determined as 9:16 and 9:16, a rotation parameter is determined as 0 °, and a parameter is added to the end of the live picture frame. And actually, the compensation and rotation processing is not carried out, and the packaged product is transmitted to a current pulling end. Under the condition that the stream pulling section receives the live broadcast picture data, analyzing to obtain compensation parameters which are determined to be 9:16 and 9:16, determining the rotation parameter to be 0 degree, determining that the single live broadcast picture is directly displayed without reduction operation;
in the 'Lianmai' mode, the picture display ratio is 4: 3. As shown in fig. 5 (a), before the "live-view" picture data transmission, the "live-view" picture with the picture ratio of 4:3 is subjected to the picture compensation operation to obtain the picture (b) in fig. 5, the width-height ratio of the reference picture is 16:9, and further, the operation of 90 ° rotation is further performed to obtain the target picture with the width-height ratio of the picture of 9:16, i.e., the picture (c) in fig. 5. Further, the compensation operation parameters 4:3 and 9:16 and the rotation operation parameter 90 ° are added to the frame end of the 'Lianmai' picture, and the live streaming data packet is pushed. And after the live broadcast stream data packet is acquired, the live broadcast picture data with the picture ratio of 9:16 can be directly analyzed through a decoder, and the live broadcast picture data is restored and displayed after the compensation operation parameters 4:3 and 9:16 and the rotation operation parameter of 90 degrees are acquired.
