我之前问过类似的问题，但我无法让它工作，而且由于这是一篇旧帖子，所以我正在重试。我想从 mkv 转换为 mp4，因为我的许多播放器都无法播放 mkv。要么他们无法播放，要么即使我不想播放字幕也会播放。我想要的是音频是不同语言的英语字幕。这是我的基本代码，其中包含一个不起作用的字幕命令：for %i in (*.mkv) do (ffmpeg -i "%i" -acodec aac -vcodec h264 -sn -filter_complex [0:v:0][0:2]overlay "%~ni".mp4)。在我处理的文件中，[0:2] 是当人们说英语以外的语言时强制使用的英语字幕。我做错了什么？

您可以使用字幕过滤器刻录基于文本的字幕流：
ffmpeg -i file -acodec aac -vcodec h264 -sn -filter_complex subtitles=f=file:si=2 out.mp4
请参阅字幕过滤器的文档：http://ffmpeg.org/ffmpeg-filters.html#subtitles-1
