foobar2000 fails to read the mkv video

Hi, I'm currently using foobar2000 v2.0 beta12 and I found it fails to play mkv videos I downloaded using yt-dlp from youtube. The common part of these mkv videos is that they're Google/On2's VP9 Video (VP90) + Opus Audio (Opus), reported by VLC. But when I extract the audio track to .mka file using LosslessCut and MKVToolNix, it plays fine.
Here's sample. What's the problem here?

I was able to play the audio part of your sample using ffmpeg wrapper + ffmpeg and adding "MKV/*.MKV" to the ffmpeg conffig in foobar.

I don't know how to play video in foobar, but there's this: https://fy.3dyd.com/
Thanks for recommendation, it works now with this component, but what about the built-in support for webm/mkv?...

Foobar is an audio player, and those containers are mainly used for video, so it's not likely they will be added.

fb2k plays .mkv files just fine in my daily use.

Mkv is a container format, kinda depends what's in it to play fine on foobar2000.

@qazmko1029 : Upgrade your yt-dlp? It uses IDMmkvlib ... mine does not.
I tracked down the video and yt-dlp'ed it - what I got, plays just fine with foobar2000.

Comparing your mkv and mine, the offending file has a total duration, but lacks a <DURATION> tag for each stream.
ffmpeg -i yourfile.MKV -codec copy fixedfile.mkv
fixes the container. (And is lossless.)

Edit: You can also use the official mkclean tool. https://sourceforge.net/projects/matroska/files/mkclean/
The file seems valid though.

This really solved my confusion, thanks a lot!
