Playing Two Video Tracks Simultaneously in the Same Window

[Heralthor]

I have several videos with two video tracks, and I'd like to play both tracks side by side simultaneously. I've discovered that if I open the video file, it will play Track 1. I can then go to Video -> Video Track -> Track 2, which opens up the second track in a second window.

This is not ideal. Is there a way to play both video tracks in the same window? Is there also a way to arrange the two tracks and overlay them (say if I want a picture-in-picture type of setup)?

I would appreciate any insight the community can provide. Thanks!

Hi, you can use the mosaic stream filter in order to achieve this effect.

Unfortunately, there's no updated documentation for this (https://docs.videolan.me/vlc-user/3.0/e ... osaic.html) so the only resource currently is https://wiki.videolan.org/VLC_HowTo/Make_a_mosaic/.

I suppose that's one approach, but it seems like overkill. All I really need is something like this:



Is there a simpler way to do it?

The GUI does not support such a fringe use case. It already has more features than can be documented and remembered by a single person...

Again, you can do that with mosaic (but it's quite inefficient and awkward). Or you can implement your own window module.

It's too bad. If we can play two tracks in two windows, I imagine it would be trivial to play two tracks in one window.

What do you mean by a window module? I'd be willing to look into that more.

Also, if VLC just can't do this, are there other media players that can?

1) I don't think it's not that simple.
2) I mean a VLC module with vout window capability.

Maybe GridPlayer is what you're looking for:

It is based on VLC.
