How to convert a .mp4 file (downloaded from YouTube) to .ogg? (keeping only the audio)

When Ubuntu had ffmpeg I could just do ffmpeg -i file.mp4 -acodec vorbis file.ogg

Now we have to do without ffmpeg, but avconv seems to have a different syntax:

$ avconv -i file.mp4 -nv file.ogg
Unrecognized option 'nv'.
Error splitting the argument list: Option not found
  • Have you tried using the same syntax as ffmpeg? – saiarcot895 Jun 8 '14 at 14:22
  • @saiarcot895: Yes, it results in an empty file. – Nicolas Raoul Jun 8 '14 at 14:38

@Nicolas Raoul you made a little mistake, it's not -nv it's -vn try:

avconv -i file.mp4 -vn file.ogg

it will work.

  • In the event that subtitle stream would be present in the file (i'm unsure if MP4 have them), you can also specify -sn to be safe. – v010dya Nov 10 '14 at 9:10
  • How about compression? My downloaded mp4 file 6.5 mb and converted oog file is 33.5 mb. There is a huge difference. How can reduce converted file size? – tersakyan Nov 15 '14 at 2:04

    @tersakyan: Interesting, but please ask this as a new question :-) – Nicolas Raoul Nov 15 '14 at 3:13
  • Unfortunately and disappointedly your answer isn't working for me, it gives Output file #0 does not contain any stream in the console/terminal. – Vicky Dev Feb 5 '16 at 11:33
  • did you try it on other files? – JoKeR Feb 8 '16 at 10:09
