How do I load an mp4 video with multiple audio tracks into blender?

Question

I've recently started using OBS multiplatform to record game play. I currently have it set to record sounds on 2 different tracks. The first for system sounds (like gamesound, mumble, etc.) and the second to record the mic.

I am able to switch between tracks when I play the unedited video using VLC, but when I load the mp4 into blender, I only get track 1.

Did I do something wrong, or does blender vse not support multiple tracks?

UPDATE

For now, it seems like the solution will be to use an external tool to get the second audio track and import it into blender afterwards. A bug report has been logged with the Blender bug reporting tool.

UPDATE 2

The bug report has been closed/archived with the gist being "not a bug". It has been added to the TODO list. If you are looking to have support for multiple audio tracks, I would suggest looking at other video editing software until Blender adds support for this feature.

And maybe you could also file a bug report/feature request, because it could be useful, and not too difficult for devs to implement (it's just typically unusual). — m.ardito, Oct 11 '15 at 20:31
Rather than updating your question with your answer you should answer your own question. ;-) — Samoth, May 18 '16 at 09:27

Nearly 5 years later, looks like Blender still doesn't support this. Something as basic as Audacity has no problem with this. I think this is a huge feature oversight! — JoelAZ, Aug 03 '20 at 03:04

Blender does not currently support the importing of multiple audio tracks that are encoded into video containers. It will typically import the first track, though I'm not certain. I recommend that you use a program like Davinci Resolve which is free to use and is much better suited for video editing and has a faster viewport for video editing. I was once in a similar situation like you with multiple tracks of audio when using OBS.
