I admit that i've been confused with "this change violates use flag constraints" and all the stuff "cpu_flags_x86_avx2? ( cpu_flags_x86_f16c ) cpu_flags_x86_f16c? ( cpu_flags_x86_avx )..." Now, i understand the meaning of use_flag1 (use_flag2). I have to emerge opencv as kdenlive is installed and needs mlt which needs opencv... so... Thanks again, Regards, -- Jacques
