audiomixer: N individual mixes, cancel out own contribution
I want to generate N individual mixes for each sink pad with its own contribution canceled out (mix-minus). While the idea and the algorithm seem to be straightforward I am not really sure whether it can be implemented without major revisions of GstAggregator and GstAudioAggregator -- they seem to imply the use of only one src pad. Can you advise on this?
I already achieved what I wanted through the use of audioinvert and an additional audiomixer, but the performance is poor
