Play separate video and audio files together

[italodeandra]

Hi, it's been ages I've been searching for this. I would like to be able to play two separate files, the video and the audio, the same way YouTube does it for saving space on high quality videos.

Things I tried:

• HLS: I can't convert the files to be a different type, they come from a server that I don't have control of.
• <vds-media-sync: It doesn't work on some mobile browsers (I tested on several iOS) or TV browsers, you can only have one playback at a time.
• media-group: It also doesn't work on mobile browsers or TV browsers.
• Mux.com: The only thing we could do was using Mux for creating a playback with two assets. But they are too expensive and out of question.

I know this isn't on the plans for Vidstack, but I really would appreciate if someone had any information on this, anything that could help lead me into something that would work.
