我认为您不能仅在视频标签中更改音频的来源.

I don't think that you can change the source of the audio only in your video tag.

所以，是的，将视频静音并隐藏音频是最简单的解决方案.

So yes, the hack of having the video muted and a hidden audio would probably be the simplest solution.

***的办法肯定是在服务器端使用您想要的视频音频源来重建视频.

The best one would certainly be to rebuild your video, server-side, using the audio source you want for that video.

为此，我将使用ffmpeg: https://superuser.com/questions/1137612/ffmpeg-replace-audio-in-video
