Comment (by PassingStrike):

 Replying to [comment:12 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.

 1) No, I just updated to 18.1.3 and both renaming the .webm to .mkv and
 using '''ffmpeg -i input.webm output.mkv''' don't work. If you are talking
 about the -1.mkv, of course it does. I just said it was recoded with
 Handbrake and that it worked (in DR 18.1.2).
 2) Glad to know I was right. As I said, I knew that just recoding it to
 .mp4 works, but I wanted to know why recoding it to .mkv didn't work.
 3) Yes, that works. Thank you very much.
