Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
Fig. 1 is a flowchart illustrating a video delivery method according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the method includes steps 101 to 103.
In step 101, a video distribution command is received. In the present disclosure, the source of the video issuing command is not limited, as long as the server receives a command for instructing that a specific video needs to be issued.
In step 102, in the case of receiving the video delivery instruction, determining a video resource packet corresponding to the first to-be-delivered video specified by the video delivery instruction, where the content in the video resource packet is already configured in the server and can be dynamically configured in the server. The video resource package comprises a second video to be issued corresponding to the first video to be issued, the second video to be issued is the first video to be issued after transparency and RGB values are separated, each frame of video frame in the second video to be issued is divided into two parts, the pixels of the first part are used for storing the transparency of each pixel point in the corresponding video frame in the first video to be issued, and the pixels of the second part are used for storing the RGB values of each pixel point in the corresponding video frame in the second video to be issued. After the server receives the video issuing command, the first video to be issued is determined according to the appointed video which is indicated to be issued to the user terminal in the command, and the resource package which is actually required to be issued to the user terminal is determined according to the first video to be issued. The first video to be issued is the original video animation, wherein each pixel in each frame of video frame comprises an RGB value and a transparency, and the video animation with the transparent channel cannot be directly decoded and played on the user terminal. And the resource package to be transmitted to the user terminal, which is determined in step 102, includes the second video to be transmitted after the separation process of the transparency and the RGB values. Therefore, the user terminal can directly play the video according to the received resource packet, so that the user of the terminal can see the playing effect of the first video to be issued.
Each video frame in the second video frame to be issued comprises two parts which are respectively used for storing the RGB value and the transparency of the corresponding video frame in the original video. For example, as shown in fig. 2, the picture of the 10 th frame of the second video frame to be distributed may be divided into two parts, namely a first part 1 and a second part 2, as shown in the figure, the transparency included in all the pixel points in the 10 th frame of the first video to be distributed is stored in the pixel points in the first part 1, and the RGB values included in all the pixel points in the 10 th frame of the first video to be distributed is stored in the pixel points in the second part 2.
The pixel points in the second portion 2 correspond to the pixel points in the 10 th frame of video frame in the first video to be transmitted one by one, for example, the RGB values stored in the pixel points at the first row and the first column position in the second portion 2 are the RGB values in the pixel points at the first row and the first column position in the corresponding video frame in the first video to be transmitted.
The pixel points in the first portion 1 and the pixel points in the 10 th frame of video frame in the first video to be distributed may also be in one-to-one correspondence, but the distribution position of the transparency stored in the first portion 1 may be different from the distribution position of the transparency of each pixel point in the 10 th frame of video frame in the first video to be distributed, that is, the transparency may not be stored in such a way that each pixel point stores the transparency of one corresponding pixel point, but a plurality of transparencies may be stored in each pixel point, for example, three transparency values of the pixel points at the first row, the first column, the second column, and the third column of the first row of the original video frame may all be stored in the pixel point at the first row, the first column of the second portion 2 in the second video to be distributed, and the three transparency values may be stored in the three positions originally used for storing RGB values in the pixel point, the transparency of all the pixel points in the original video frame can be stored in a part of the pixel points in the corresponding video frame in the second video to be issued, so that the transparency of a plurality of the pixel points is compressed to one pixel point to be represented, the user terminal can be enabled to analyze the video frame, the video volume of the second video to be issued can be reduced to a certain extent, the bandwidth occupied by the video to be issued is reduced, and the video issuing speed can be effectively improved.
Fig. 2 is only to illustrate that a video frame in a corresponding second video to be delivered after a video frame of a first video to be delivered is subjected to transparency and RGB value separation includes two parts in which the transparency and the RGB value are respectively stored, and is not used to limit that video pictures of the first part 1 and the second part 2 must be consistent, nor is it used to limit specific picture content in the second video to be delivered.
In step 103, the determined video resource packet is sent to a designated terminal according to the video issuing instruction. And after determining the resource packet to be issued, sending the determined video resource packet to a specified user terminal according to the video issuing instruction.
For example, in a live scene, a user may generate some interactive operations when watching a live broadcast in a terminal, such as delivering a main broadcast gift, and the like, when a part of the gift is delivered, a corresponding animation video needs to be displayed to implement a special effect of delivering the gift, and the corresponding animation video needs to be delivered from a server to the terminal for caching when a client of the terminal is started or at other specific time, so that the client of the user terminal triggers the video delivery process shown in step 101 to step 103 when determining that a corresponding animation video resource needs to be cached from the server.
Through the technical scheme, when the server needs to send the video animation to the terminal, the transparency and the RGB value of each frame of video frame in the video animation can be separated in advance, each frame of video frame comprises two parts, and the transparency and the RGB value in the original video frame are respectively stored, so that the user terminal can directly analyze and play the video animation according to the received video animation, the problem that the video animation with the transparent channel cannot be directly issued to the user terminal to play can be solved, the restoration degree of the video animation can be ensured, the realization cost is greatly reduced compared with other solutions, and the user experience is further improved.
In a possible implementation manner, the video resource package further includes a configuration file corresponding to the second video to be delivered, where the configuration file is used to provide a corresponding clipping alignment manner when the second video to be delivered is mapped to the texture coordinate of the designated terminal. When videos of the same format are played on different terminals, due to the difference of terminal model types, videos of the same fixed size may show different sizes on different terminal model types, so that the configuration file can provide cutting alignment modes suitable for different model types when the second video to be distributed is played by the terminal, and when the second video to be distributed can be mapped to texture coordinates on a designated terminal, mapping can be adjusted automatically according to the cutting alignment modes given in the configuration file, so that the terminal of any model can display video animation of which size is most suitable for the model of the terminal according to the second video to be distributed and the cutting alignment modes in the configuration file.
In a possible implementation manner, the second video to be delivered in the video resource package includes a horizontal screen video to be delivered corresponding to the first video to be delivered of the horizontal screen and a vertical screen video to be delivered corresponding to the first video to be delivered of the vertical screen. In a live scene, the first to-be-transmitted video of the cross screen may be a gift-offering video animation played when the terminal plays a live screen on the cross screen, as shown in fig. 3 a; the first video to be delivered of the vertical screen may be a gift-offering video animation played when the terminal plays a live-broadcast picture in the vertical screen, as shown in fig. 3 b. Both videos need to be sent to the user terminal so that the user terminal can display video animation with a proper size in different display pictures, and therefore after the transparency and the RGB value of the first video to be distributed are separated, the obtained second video to be distributed includes both the horizontal screen video to be distributed and the vertical screen video to be distributed, that is, the horizontal screen video to be distributed and the vertical screen video to be distributed, which are separated by the transparency and the RGB value, in the video resource packet to be sent to the specified terminal and determined by the server in step 102, respectively.
Fig. 4 is a flowchart illustrating a video delivery method according to still another exemplary embodiment of the present disclosure. As shown in fig. 4, the method includes step 401 in addition to steps 101 to 103 shown in fig. 1.
In step 401, the second video to be delivered is re-encoded to reduce the volume of the second video to be delivered. For example, the second video to be transmitted may be converted into h265 format, so that the volume of the converted video file can be greatly reduced compared with the volume of the conventional h264 format video file. And after the second video to be transmitted is re-encoded into the h265 format, the decoding and playing of the designated terminal receiving the second video to be transmitted are not affected, and the designated terminal can still finish the decoding and playing of the second video to be transmitted in the h265 format. In addition, most of the models of the terminals can support hardware decoding at present, and the designated terminal can decode and play the second video to be transmitted in the h265 format more quickly after receiving the second video to be transmitted by starting the hardware decoding on the designated terminal. In a possible implementation manner, when the second video to be delivered includes a horizontal screen video to be delivered and a vertical screen video to be delivered, both the horizontal screen video to be delivered and the vertical screen video to be delivered are re-encoded, reduced in volume, and then sent to the designated terminal.
Fig. 5 is a block diagram illustrating a structure of a video distribution apparatus according to an exemplary embodiment of the present disclosure. As shown in fig. 5, the apparatus includes: the receiving module 10 is used for receiving a video issuing instruction; a video determining module 20, configured to determine, when the video issuing instruction is received, a video resource packet corresponding to a first video to be issued specified by the video issuing instruction, where the video resource packet includes a second video to be issued corresponding to the first video to be issued, the second video to be issued is the first video to be issued after transparency and RGB values are separated, each video frame in the second video to be issued is divided into two parts, each pixel in the first part is used to store the transparency of each pixel in the corresponding video frame in the first video to be issued, and each pixel in the second part is used to store the RGB value of each pixel in the corresponding video frame in the second video to be issued; and the video issuing module 30 is configured to send the determined video resource packet to a specified terminal according to the video issuing instruction.
Through the technical scheme, when the server needs to send the video animation to the terminal, the transparency and the RGB value of each frame of video frame in the video animation can be separated in advance, each frame of video frame comprises two parts, and the transparency and the RGB value in the original video frame are respectively stored, so that the user terminal can directly analyze and play the video animation according to the received video animation, the problem that the video animation with the transparent channel cannot be directly issued to the user terminal to play can be solved, the restoration degree of the video animation can be ensured, the realization cost is greatly reduced compared with other solutions, and the user experience is further improved.

In a possible implementation manner, the second video to be delivered in the video resource package includes a horizontal screen video to be delivered corresponding to the first video to be delivered of the horizontal screen and a vertical screen video to be delivered corresponding to the first video to be delivered of the vertical screen.
In a possible implementation manner, among the partial pixel points in the first portion of each video frame in the second video to be distributed, the transparency of three pixel points in the corresponding video frame in the first video to be distributed is included.
