hi, > -vop has been removed, use -vf instead. > > mplayer on commandline works well. Is this a bug in kmplayer (do they have > set the -vop flac in the code...) or is the error on my side? -vop is deprecated. -vf must be used. kmplayer default filter options use -vop. i would say it is a bug. kmplayer 0.9.4a will be uploaded today, unfortunately it will not fix it but you can expect a fix soon. cheers, Fathi
