use amix and weights

Post by tomsss » Wed Oct 03, 2018 1:08 pm

Hi,
i want to make my own 5.1 stero downmix. My code is a filter_complex "[a01][a02][a03][a04]amix=inputs=4:weights=1|0.8|0.5|0.8:duration=longest,volume=4[outa]"
This code works for the mixing, but the weights (1,0.8,.05...) does not make any changes.

Thanks Thomas

In documentation it is clearly stated that weights are separated with space, and not with '|'.
