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 :)
