I want to download a video with embedded thumbnail and convert it to mp4:

youtube-dl -t --audio-quality 0 --audio-format m4a --embed-thumbnail --add-metadata -x --metadata-from-title '%(artist)s - %(title)s' --ignore-errors https://www.youtube.com/watch?v=FyASdjZE0R0

The conversattion to mp3 works propberly, but to m4a it fails:

Did it with the original compilation guide: https://trac.ffmpeg.org/wiki/CompilationGuide

Problem persists:

ERROR: audio conversion failed: [aac @ 0x1d591c0] Alternatively use the non experimental encoder 'libvo_aacenc'. ERROR: Only mp3 and m4a/mp4 are supported for thumbnail embedding for now.

I tried to convert the webm via ffmpeg to m4a directly, this works. So this problem seems to be linked with youtube-dl.

Currently youtube-dl favors avconv over ffmpeg. Add --prefer-ffmpeg to use ffmpeg.
