Problems solved by technology
Common video playback software, such as windows mediaplayer, Baofengyingyin, etc., do not support the playback of media files in FLASH format
The FLASH player based on the FLASH playback control does not support video or other format files
[0003] Some early workarounds were to transcribe FLASH format animations into MPG format video programs, but this solution was time-consuming and could not be quickly generated for on-site application
[0004] In addition, since the player has to monopolize the screen or display device during playback
At the same time, the screen only displays one playback file, and it is difficult to display and play two video files or two media files of different formats at the same time
Therefore, even if the player or advertising player on the market supports both SWF format FLASH files and MPG format video files, they can only open the video files on the premise of closing the FLASH file playback, and cannot play both on the screen at the same time. media files in different formats
[0005] Based on the above reasons, it is generally difficult to play video files and FLASH files on the same platform in the field of engineering applications
If you forcibly play unsupported media formats on a single platform, such as playing FLASH files on Baofengyingyin, it is likely to cause the playback platform to crash or restart

Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0040] Such as figure 1 As shown, the present invention includes a central processing module, a video processing module, a display control module, a memory control module, an audio processing module, an SD reading and writing module, and a communication module;
[0041] The memory control module includes a dual-channel memory controller and a non-volatile memory, wherein the design of the dual-channel controller greatly improves memory read / write efficiency, and uses different memory areas for processing parts of different modules, reducing memory read and write efficiency. / write conflict occurs. This module is used to store media stream data that needs to be decoded.
[0042] The communication module includes a USB data interface, a GPS interface, and an SD card read and write channel. Among them, the SD read-write module has a restricted...

The invention relates to media play field, in particular to an advertising media player which can simultaneously support video files and flash files under the single play platform in Linux system and a play method thereof. The detected media stream data is transmitted to a central processing module to be analyzed, and the analyzed video file or / and flash file are decoded; the decoded media streamfile is stored in a specified memory control module, and at last the media stream data is called from the memory control module and transmitted to a display control module for division output. The device has the advantages that after the format of a media file is judged by a media player, different play kernels are called to combine play two formats of media files on a Linux single platform, and the applicability of the player is improved.
Description
Contents of the invention [0001] The invention relates to the field of media playing, in particular to an advertising media playing device and a playing method thereof which simultaneously support video files and FLASH files under a single playing platform of a Linux system. Background technique [0002] Video files and FLASH files are completely different types of media representations. Common video playback software, such as windows mediaplayer, Baofengyingyin, etc., do not support the playback of media files in FLASH format. However, the FLASH player based on the FLASH playback control does not support files in video or other formats. [0003] Some early workarounds were to transcribe animations in FLASH format into MPG format video programs, but this solution was time-consuming and could not be quickly generated for on-site application. [0004] In addition, since the player has to monopolize the screen or display device during the playback. At the same time, the scre...
