Comment (by Mads Johansen):

 1) The mkv file you made works in DR 18.1.3 on windows (both audio and
 video).
 2) Renaming the webm to mkv shows the video but no audio (because DR does
 not support opus audio)
 3) So the problem is not ''ffmpeg -i xyz.webm xyz.mkv'', but that you need
 to do ''ffmpeg -i xyz.webm -c:v copy -c:a aac -b:a 320k -ac 2 -ar 48000
 xyz.mkv'' (where xyz is the file name), to copy the video and convert the
 audio to a DR supported codec.
