Yesterday I installed the latest Kubuntu release 14.04. So I meet a little problems with the media conversions. The old FFmpeg is finally replaced with avconv which is in the libav-tools library. Till now i was using ffmpeg and every mp4 or flv to mp3 conversion was very fast. For example if one file around 5mins length was converted for ~20secs, now the same file is converted ~3-4-5 times slower. I read everywhere, but could not find where is the problem.. Is there any cure about that?
Best regards 🙂

So the answer is in one simple parameter -vn which disable video recording for the output which is actually unneeded when making conversion from mp4(probably every video file) to mp3.
‘-vn (output)’ Disable video recording.
In my case I'm using Download Helper for Firefox. I made custom mp3 conversion where added this parameter there and now everything is even faster than ffmpeg.
