but these are no debian builds and without repeatable builds you can't
prove it nor proves a binary with a different hash build from the
sources that these where not used for the shipped binary
without the 100% exactly build environment including all versions of
involved software and libraries you can't prove it

as said: in some cases, in a closed appliance you would even have a
problem to prove that ffmpeg exists there at all
