ERROR: audio conversion failed: "debug" (Wrong FFMPG Parameters)

[wastene]

Versions:

• youtube-dl 2019.03.01
• avconv version (ffmpeg) 11.12-6:11.12-1~deb8u1+rpi1

Running on a Raspberry Pi 3B

Executed Command:
youtube-dl -x --audio-format mp3 https://youtu.be/GK5hf8ZsUr4

Log of this Execution is below

FFMPEG Command Line not working:
ffmpeg -y -loglevel repeat+info -i 'file:Kontra K - Farben (Official Video)-GK5hf8ZsUr4.webm' -vn -acodec libmp3lame -q:a 5 'file:Kontra K - Farben (Official Video)-GK5hf8ZsUr4.mp3'

FFMPEG Command Line working:
ffmpeg -y -loglevel debug -i 'file:Kontra K - Farben (Official Video)-GK5hf8ZsUr4.webm' -vn -acodec libmp3lame -q:a 5 'file:Kontra K - Farben (Official Video)-GK5hf8ZsUr4.mp3'

If I execute the FFMPEG Command Line I get the error that the Log-Level "repeat+info" is not available. If I replace this with another log level (for example "debug") the conversion is working. Maybe you just need to change the parameters for calling the FFMPEG Command line.

Thanks.

Your ffmpeg is symlinked to avconv that does not support repeat+. Fix that.
