Add Audio Track Switching in Player Interface

[anand-lyn]

Add dedicated audio track control options in the player interface (e.g., a dropdown menu or toggle buttons) to:

1. Display a list of available audio tracks (with track names if metadata is present, e.g., "Vocal", "Accompaniment")
2. Allow one-click switching between audio tracks during playback
3. Remember the last selected track for each media file (optional, but highly appreciated)

Thank you for your great work on this project! This feature would significantly improve the karaoke experience for users who rely on multi-track media files.

Hi, where can I find these multi-track files, or similar sample files?

@bhj I have an MKV video file where Audio Track 1 is the original vocal and Audio Track 2 is the instrumental (backing track). I need to be able to switch between these audio tracks to toggle the vocals on and off.

Yes, this is one of the reason i have not use karaoke eternal yet. Sometimes i would like to learn a song and i want to switch it to original vocal instantly.

i have files of mkv and mp4 that have Audio Track 1 is the original vocal and Audio Track 2 is the instrumental track. This addition will be very useful.

+1 for this feature. I'd also like to switch between vocal and instrumental tracks during playback.

My setup: Youka-generated karaoke (MP4) + Karaoke Eternal. I have MKV/MP4 files where Track 1 is original vocal and Track 2 is instrumental. Being able to switch on the fly would help when learning a song (listen with vocals) and then singing along (instrumental only).

This would address one of the main gaps I've found compared to other karaoke players: pitch control and vocal toggle are essential for a lot of users. Audio track switching would cover the vocal toggle use case very well.

I'm in favor of it. MKV containers aren't well-supported outside of Chromium-based browsers as of this writing, so that would probably be a different issue to tackle.
