An embodiment of the present disclosure provides a method for displaying and processing media files.

In some of these embodiments, the display processing method of the media file is applied to a display device, as shown in FIG. 1, the method includes the following steps:

Step 101: Obtain media files and presentation requirements for the media files.

Step 102: Determine the presentation status of the media file according to the presentation requirement and the status of the display device.

Step 103: Display the media file according to the display state.

In this embodiment, display requirements are set for media files to be displayed, and the display requirements include one or more of media information, display page information, content container information, and content information.

Here, the media information includes information about the number of display pages. In this embodiment, media files can be displayed on one or more pages, and each display page is called a display page.

Each display page includes at least one content container, and the content material may be a content container such as a player instance, and media files are displayed in the content container according to the set rules.

The embodiment of the present disclosure defines the definition information of the content container in the display page through the display page information. The definition information includes related definitions such as the position of the content container in the display page and the display time of the content container. Based on the definition information, it is possible to determine the The display process of each content container.

The content container information is used to define the display status of the target content in the content container. It should be understood that the target content can be displayed in different ways. Exemplarily, for a video file, it can be played in a loop or in a single play.

The content information is used to define the attributes of the target content. Different content can be displayed in different ways. At the same time, there are different display requirements. For example, for image files, the display order needs to be defined, and If the target content also includes video files, it may also include related adjustment settings such as volume and playback speed. By clarifying the attributes of the target content, more accurate control over the process of displaying the target content can be achieved, which helps to improve the display effect.

In the technical solution of this embodiment, through the combination of media information, display page information, content container information and content information, the definition of the display status of different types of media files can be completed from simple to complex, based on the determined In the display state, the display device as a display terminal can arrange, adjust, and transcode the media files according to the performance parameters of the display device when the display state is satisfied. In this way, the media files sent based on the content platform can be effectively displayed. Adapt to different display devices, and the display device can perform transcoding and arrangement processing on its own according to its own performance parameters for media files pushed based on different operating systems, encoding formats, etc., and can also display according to display requirements, improving compatibility and applicability.

determining the program material and background material of each display page based on the material path;

In this embodiment, the program information of each media file includes a unique program number and program name, and the media files can be identified and distinguished based on the program information of the media file.

The material required by the media file is stored in a specific storage space. During implementation, the material path can be accessed based on the program information to obtain the relevant material. Relevant materials specifically include program materials and background materials, wherein, program materials refer to materials related to content, and background materials refer to materials that form the program background of media files. Exemplarily, they can be background music, background pictures and One or more of the background colors. Among them, when the background material includes background pictures and background colors, the priority of the background picture is higher than that of the background color. It can be understood that the picture is preferentially used as the program background of the media file. The information uses the background of the selected color.

The duration is used to define the total playing duration of the program corresponding to the media file.

The media information may also include settings for volume and whether to mute, so that the overall display volume and mute status of the media file may be determined.
