Keep getting invalid argument on known good files mkv files.

I cannot play these h.265 files. I get invalid arguments.  Does anyone have any ideas?  Thank you!

@richlee91are you still having an issue with this? If so, can you please provide a sample file for testing? Thanks !

I'm experiencing a similar issue. The MKV files themselves are fine — it appears to be a naming-related problem.

Here’s an example file path:

/media/tv/Show Name (2025) [imdb-tt12345678]/Season 01/Show Name - S01E01 - TBA [ABC WEBDL-1080p][AAC 2.0][h264]-ABC.mkv

Interestingly, I have another episode with the exact same naming format that works without any issues.

Renaming the file resolves the problem, which leads me to suspect it might be related to an encoding issue — possibly involving special characters. I noticed that one of the filenames included the Turkish "ı" (dotless 'i'), which may be causing parsing or recognition problems in some systems.
