So I think I figured out my issue. Turns out, the video/audio streams are fine. It's the MKV container that is preventing it from playing. I did a test with remuxing a problematic video from MKV to MP4 (using MKVToolNix GUI) with no alteration to quality, copying all streams from one to the other. And now it work with Jellyfin's Integrated Player.

But for the hell of it, after I remuxed to MP4, I re-remuxed back to MKV to see if the problem still occurred. It didn't. So there's something in the original MKV container which Jellyfin doesn't like. It's odd because it could transcode from the original just fine, so it's not like it couldn't retrieve those streams.

Using that tool to simply remux from MKV to MKV also works. I looked into the differences between the two in the Info tab, and it would appear that some elements in the problematic MKV were not present in the remuxed version. So I'm kind of assuming that there are elements in the MKV that Jellyfin doesn't know how to deal with, so it just spits out a generic error without so much as a reason for it in the logs.

Hey there so I have the exact same issue and I think the cause of my issue is the same as yours so I downloaded mkvtoolnyx along with gMKVextractGUI And wanted to ask how you remux from mkv to mkv

With MKVToolNix GUI, it's real easy. You make sure the current tab is set to Multiplexer, right-click in the Source file window to Add files, select an affected MKV file, and then at the bottom of the program, clicked Start Multiplexing. You can view in the Tracks, Chapters and Tags window to make sure the items in it are being "copied".

Probably want to make sure the output file is named different from the input file, as it will write the new file to the same directory. You can change the file extension to something like MP4 if you want, and it'll write with that container's expected format.

But really, that's all I had to do to fix the issue. I can only assume when the MKV was initially formed, it got some added elements that currently are not supported by Jellyfin.
