In this mode we accept previously set filter caps until upstream renegotiates to something that is compatible to the current filter caps. This allows dynamic caps changes in the pipeline even if there is a queue between any conversion element and the capsfilter. Without this we would get not-negotiated errors if timing is bad. https://bugzilla.gnome.org/show_bug.cgi?id=739002
