The or behavior you see when playing the file.
Open your mime.types file or add this line to your server block: video/x-matroska mkv; Use code with caution. Restart Nginx afterward.
The web server does not recognize the .mkv extension and blocks the download or stream.
Whether you're using a dedicated hosting provider, a custom server address, or your own home-built machine, the principles are the same. The MKV format provides exceptional quality and flexibility for your media collection, while a dedicated media server—like Plex or Jellyfin—provides the intelligent processing and delivery system to make that media playable on any device, anywhere.
If your MKV video plays but buffers constantly, your server is struggling to transcode the file. Transcoding converts the MKV file into a format your device can read (like MP4 with AAC audio) in real-time. Navigate to your MyServer settings dashboard. Locate the or Media Processing menu.
