Works for me, but maybe you do not have the volume filter, which is part of the normalize module, which is GPL and requires a build with --enable-gpl. You can also use the sox filter, which does not require GPL: <filter> <property name="effect">vol 0.083</property> <property name="mlt_service">sox</property> </filter> -- +-DRD-+ |
