Problems solved by technology

[0002] At present, the implementation cost of dynamic multimedia information (such as dynamic advertisement) is relatively high. After the front-end signal is collected, it needs to be processed by a hardware subtitle machine before it enters the director switcher. Human intervention is necessary, and it is impossible to intelligently control the frequency of dynamic multimedia information and follow the Playing dynamic multimedia information sequentially in a list requires a lot of machine and labor costs. If the front end does not have processing equipment such as a hardware subtitle machine, the effect of dynamic multimedia information cannot be realized.
[0003] Dynamic multimedia information is added to the live streaming screen as a video clip. Due to the constraints of the video format (the pixel format that is decoded and played after video compression and encoding is usually YUV420P, without any transparency), the entire content of the dynamic multimedia information screen area includes The bac

Embodiment 1

[0038] The embodiment of the present invention provides a multimedia information processing method, which is applied to the server side; figure 1 Schematic diagram of the implementation process of a multimedia information processing method provided by the present invention; figure 1 As shown, the method includes:

[0039] Step S101: Obtain N pieces of first information, where N is a positive integer, and the type of the first information matches the first preset strategy to support the synthesis of the first multimedia information;

[0040] Specifically, the first information may refer to a picture, but is not limited to a picture. For example, the first information may also be a presentation, a file, and the like.

[0041] The following takes the first information as a picture as an example to illustrate how to determine the number of N.

[0042] Assuming that the number of frames per second (FPS, FramesPerSecond) is 25, and the dynamic multimedia information provider needs to play dy...

Embodiment 2

[0098] The embodiment of the present invention provides a method for generating first multimedia information, and the method is applied to a server, figure 2 A schematic diagram of the implementation process of generating the first multimedia information provided by the present invention; figure 2 As shown, in this embodiment, assuming that the first information is a picture in png format, the method includes:

[0099] Step S201: Read the first picture among N pictures;

[0100] Assuming that the provider requires the production of first multimedia information with a duration of 10 seconds, in this embodiment, the first multimedia information can be understood as a marquee advertisement. Since the frame rate FPS=25, the provider provides 250 PNG sequence picture files, the number can be 00001.png, 00002.png, ..., 00249.png, 00250.png.

[0101] Figure 3-1 It is a schematic diagram of the arrangement of some pictures provided by the present invention, numbered from 00037.png to 0006...

Embodiment 3

[0114] The embodiment of the present invention provides a method for mixing and superimposing first multimedia information and live stream information, and the method is applied to a server, Figure 4 A schematic diagram of the implementation process of mixing and superimposing the first multimedia information and the live stream information provided by the present invention; Figure 4 As shown, the method includes:

[0115] Step S301: Determine whether it is necessary to superimpose the first multimedia information in the live stream information; if so, perform step S302; if not, perform step S305;

[0116] In this embodiment, it is assumed that the first multimedia information is a marquee advertisement, and the live stream information is live stream information.

[0117] Step S302: Collect the video pixel data of the current frame in the live stream information; wherein, the current frame is the Sth frame;

[0118] Here, the video pixel data of the current frame may be buffered thro...

Abstract

The embodiment of the invention provides a multimedia information processing method and a server. The method comprises the following steps: acquiring N pieces of first information, wherein N is a positive integer, and a type of the first information is matched with a first preset strategy in order to support synthesis of first multimedia information; generating the first multimedia information by the N pieces of first information according to the first preset strategy, wherein the first multimedia information carries key information; and loading live streaming information to play, and mixing and overlaying the first multimedia information and the live streaming information according to a second preset strategy when the need of overlaying the first multimedia information in the live streaming information is detected in order that the key information in an obtained overlaying picture is presented together as foregrounded information of the live streaming information, and converted to a standard digital video compression format to be played by terminal equipment.

Description

Technical field [0001] The invention relates to information processing technology, in particular to a multimedia information processing method and server. Background technique [0002] At present, the implementation cost of dynamic multimedia information (such as dynamic advertising) is relatively high. After the front-end signal is collected, a hardware subtitle machine needs to be introduced before entering the switcher. Human intervention is necessary. It is impossible to intelligently control the frequency of dynamic multimedia information and follow To play dynamic multimedia information in a list order is expensive in terms of machine and labor costs. If the front end does not have processing equipment such as a hardware subtitle machine, the effect of dynamic multimedia information cannot be achieved. [0003] Dynamic multimedia information is added to the live stream screen as a video short film. Due to the restriction of the video format (the pixel format after video compr...
