Output #0, srt, to 'English.srt':
Output file #0 does not contain any stream

知道哪里出了问题吗？

答案1

遵照你的命令，

ffmpeg -i Silence2016.mkv English.srt -map 0 -map 1 -c copy output.mkv

SRT 文件名前面没有-i，所以 ffmpeg 认为它是输出文件的名称。通常，ffmpeg 会从可以复用到输出的输入中选择一个流，但由于 MKV 没有子流，因此没有要转码的流。不幸的是，当 ffmpeg 打开 SRT 进行写入时，SRT 几乎肯定已被清除。

如果您有 SRT 的备份，请使用

ffmpeg -i Silence2016.mkv -i English.srt -map 0 -map 1 -c copy output.mkv
