流媒体文件是流媒体系统处理的主要内容,任何要发布的内容都经常是以文件的形式存储和传送,即使是直播方式也要经过压缩,按照一定的格式传送给用户;用户检索媒体文件往往并不是直接获取文件,而是经过一个中间文件(媒体发布文件)。根据这些媒体发布文件的不同用途,我们将它们分为媒体压缩格式、媒体流格式、媒体发布格式。本文分别对上述三种文件格式进行介绍。 Streaming media files are the main content of streaming media system. Any content to be released is often stored and transmitted in the form of files. Even the live broadcast mode must be compressed and transmitted to the user according to a certain format. The user retrieves the media files often Instead of getting the file directly, it goes through an intermediate file (the media releases the file). According to the different uses of these media release documents, we divide them into media compression format, media stream format and media release format. This article separately describes the above three file formats.
