I have .mp4, .m4v, and .mkv videos, all with embedded subtitles that I can see in VLC. How can I see the subtitles in Firefox?

How can I see the subtitles in Firefox? For now, subtitles are in both French and English.

That is why I can see the subtitles when I open the video file with VLC. When I put the files on my website and open them from Firefox, I get audio and video and NOT subtitles, and I have found no controls to allow me to see the subtitles.
