Problems solved by technology
This makes the media player take up a lot of computing resources when playing in reverse order. Therefore, the current mainstream media player software does not support the reverse order playback function of the directional compressed video format, and only large media editing software supports reverse order playback.

The present invention relates to a real-time streaming media player and its architecture method. The method includes: decomposing the real-time streaming media playback task into six subtasks: reading original frames, buffering original frames, decoding original frames, buffering decoded frames and sending Display frames, send display frames and playback control instructions, and cache display frames; respectively write six work classes according to the six subtasks, place the execution program code and message mapping table of each subtask in the interface of the work class, and generate six A work class instantiation object: stream pulling unit, source cache unit, decoding unit, decoding cache unit, display unit, display cache unit; write the Root class inheriting the Node class, and put the six work in the interface of the Root class Classes are loaded as children of the Root class. The present invention decomposes the real-time streaming media playing process into six different working units, and each unit is independent of each other, so that the real-time streaming media playing process has the same pause / continue function as the file playing.
Description
technical field [0001] The invention relates to the field of software design, in particular to a real-time streaming media player and its architecture method. Background technique [0002] The media content played by media player software includes two categories: file playback and real-time streaming media playback. File playback means that the media content played by the player is saved in the local or network storage space in the form of media files, such as using the media player installed in the computer to play the video and audio files on the hard disk, or viewing the files that have been saved on the server on the web page. On-demand media files and so on. In addition to storing media content information such as video and audio, these media files also store other reference information provided to the player, such as: file size, media content duration, reference frame storage location, decoder parameters, etc. The decoder can also read these reference information at ...
