Specifically, for example, program playing software at a program making end uploads media of a target program to be made, sets media attributes, media playing time and other information to make the program, the program making end sends the made target program to a program playing control end, and the program playing control end receives the target program sent by the program making end and acquires program information of the target program. Specifically, the program information may include, for example, media content, media play start time, media play duration, media attribute, media special effects, and number of frames of a program image in a unit time, and the media may include, for example, a plurality of media and a plurality of media types, for example, a picture media, a text media, a weather plug-in media, an audio media, a video media, and the like, and the media attribute may include, for example, information of a media display position, a media size, and the like, and the embodiment of the invention is not limited thereto.
Specifically, the media of the target program in the present embodiment may include, for example, a picture media (i.e., a first media) and a text media (i.e., a second media); for example: the number of image frames in unit time is 30 frames per second; the media playing time of the picture media is 20s, the picture media starts to be played from the 1 st second of the target program, and the media special effect is that the picture media enters a playing window from left to right and the special effect time is 5s; the playing time of the text media is 60s, the text media starts to be played from the 1 st second of the target program, and the media effect is that the text scrolls from right to left.
In view of the foregoing, the program playing control end may obtain, for example, the program information as described above, obtain, according to the media playing start time and the media playing duration, a playing total duration of the target program to be 60s, and then obtain, according to the playing total duration to be 60s and the program image frame number in the unit time, that is, 30 frames/s, an image total frame number of the target program to be 1800 frames, obtain, according to the information such as the picture media, the text media, the picture media special effect, the text media special effect, the picture media playing duration, and the text media playing duration, an image content corresponding to each of 1800 frames of program images of the target program, where the image content includes a media display content and corresponding display position information, and the media display content may be, for example, a display start coordinate of each frame of the media display content, a width of the display content, and a height of the display content. The image content may include, for example, a first media image (picture media image) and display position information of the first media image, a second media image (text media image) and display position information of the second media image; and then calculating the playing time of each frame of program image of the target program according to the total playing time length and the total frame number of the program images, wherein the drawing time of the first frame of program image is 1-33ms, the playing time of the first frame of program image is 34ms, the drawing time of the second frame of program image is 33-66ms, and the playing time of the second frame of program image is 67ms, which are only illustrative and are not repeated.

Specifically, for example, the program image may be drawn at the drawing time corresponding to each frame of the program image in sequence, and then the program image may be played at the corresponding playing time. Specifically, the multi-frame program image comprises a previous frame program image and a next frame program image which are sequentially played, the previous frame program image is played at the playing time corresponding to the previous frame program image, and the next frame program image is drawn according to the image content of the next frame program image; and responding to the completion of the drawing of the next frame of program image and the completion of the playing of the previous frame of program image, and playing the next frame of program image at the playing time corresponding to the next frame of program image. For example, according to the program content corresponding to the first frame program image, the first frame program image is drawn between the drawing time of the first frame program image, i.e. 1 st ms to 33 st ms, and then the first frame program image is played at the playing time of the first frame program image, i.e. 34 th ms, and the first frame program image may be played, for example, in a playing window of a program playing control end (for example, as shown in fig. 4A); then drawing a second frame program image (for example, as shown in fig. 4B) according to the image content corresponding to the second frame program image at 33-66ms, and replacing the first frame program image at 67ms to play the second frame program image; and sequentially completing the drawing and playing of 1800 frames of program images, namely completing the program playing of the target program, wherein the end time of the drawing time corresponding to the first frame of program image is the same as the start time of the drawing time corresponding to the second frame of program image, the drawing interval time of each frame of program image is the same, and the playing time interval is the same.
4A and 4B, the program playing control end draws the program image, for example, draws the media image on the canvas, firstly draws the first frame image 10 (first frame first media image) of the picture media on the picture media display position of the canvas according to the first media image content corresponding to the first frame program image and the image content of the picture media; then, a first frame image 20 (a first frame second media image) of the text media is drawn on the text media display position of the canvas, and specifically, the first frame image of the text media can be drawn according to the second media content corresponding to the first frame program image, namely, the text content of the text media, and media attributes such as word size, font, color and the like; after the media drawing on all the first frame program images is completed, the whole canvas is saved as one picture, namely the first frame program image (shown in fig. 4A). The second frame program image effect may be, for example, as shown in fig. 4B, and the specific drawing process is the same as that of the first frame program image, and will not be described herein. It is worth mentioning that in the process of drawing the program image, the canvas may be hidden, i.e. the drawing process is hidden and not displayed, so that the user experience may be improved.
It should be noted that, the target program may further include a weather plug-in media, for example, specifically, the playing duration of the weather plug-in media may be 60s, the playing is started from the 1 st second of the target program, the special effect of the media is updated every 30 seconds, the first frame of weather plug-in media is drawn on the weather plug-in media display position of the canvas, for example, the current weather information may be obtained, and then the weather plug-in is drawn according to the current weather information; the current weather information needs to be retrieved for drawing when drawing the weather plug-in media after 10 seconds.
