Http- Myserver.com File.mkv -

MKV files are often massive (4GB to 50GB). Your server must support partial content (HTTP 206). This allows the client to request only the specific bytes needed to resume playback or skip ahead.

For Apache (.htaccess or httpd.conf):

<FilesMatch "\.(mkv)$">
    Header set Accept-Ranges bytes
    Header unset Etag
</FilesMatch>

For Nginx (server block):

location ~ \.mkv$ 
    add_header Accept-Ranges bytes;
    add_header Content-Disposition 'inline; filename="$1"';
    mp4;
    # Note: Nginx's ngx_http_mp4_module works best with MP4; for MKV, rely on range.

mpv "http://myserver.com/file.mkv"

ffmpeg -i "http://myserver.com/file.mkv" -c copy file_copy.mkv
