Description (last modified by llogan)

When converting to webm with a "-q 9" argument, avconv instead uses the lowest quality conversion. As it is encoding, it says "q=0.0" and the resulting file is small in size and has bad quality.

avconv -i vid.mkv -q 9 vid.webm

You are at the wrong bug tracker. avconv is not from FFmpeg. See http://stackoverflow.com/a/9477756/1109017

If you believe there is a bug in ffmpeg from FFmpeg (using git head) then please re-open this bug report.
