So you could "reample" using opus? i.e. have one side feed 44.1 into opus encoder, then send opus over the wire, have the other side decode 48 kHz from opus? Is that true for celt 0.5.1 too btw? > So this isn't something you strictly need to coordinate between endpoints > unless they have their own requirements to do that.

Makes perfect sense. thanks, Gerd _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
