Finally, the language=eng option sets the subtitle language to English. The resulting ouptut_soft.mp4 file contains the ability to activate the subtitle file or disable it: We can also add more than one subtitle file to support subtitles in different languages by using the -map option. Here...
-metadata:s:s:0means to set the metadata for Stream:Subtitle:Number of stream, starting with 0. language=engsets the subtitle language to English. The value for this option uses theISO 639 language codewhich consists of 3 letters for every language. ...

To set the language of the first audio stream: 只看操作命令不如直接上演示: -metadata之后直接跟标签键值对则会成为全局元数据,等同于metadata_specifier=g,且每项表现都需要对应一个-metadata选项,若使用s,c,p等metadata_specifier,则分为别设置每个或具体媒体流、章节、节目设置元数据,具体可以参考FFmpeg对应...
