1. The following code in debian/rules:

LIB_PKGS2 := $(shell sed -nr 
's/^Package:[[:space:]]*(libavcodec[0-9]+)[[:space:]]*$$/\1/p' debian/control)
…
        dh_strip $(addprefix -N,$(LIB_PKGS2)) -Nffmpeg --dbg-package=libav-dbg
        dh_strip $(addprefix -p,$(LIB_PKGS2)) --dbg-package=libav-regular-dbg
