I believe it's up to the application to check if the requested codec 
actually exists and fail gracefully if not.

You betcha!

We've already been there, should be no problem to implement. On the 
other hand, now you really just have to uncomment the desired lines in 
debian/confflags and I think that's even more trivial than passing 
DEB_BUILD_OPTIONS. There is the additional advantage that you have to 
do a (very minor, though) change to the packaging in order to receive 
a changed result in the outcoming library packages. This way the 
change remains traceable in the diff.gz, which makes it far more 
reproducable than a set or unset DEB_BUILD_OPTIONS (which leave no 
trace nowhere even though resulting in modified packages).

Ftp-masters are informed and know about the situation not only since 
#522373 has been files, but *for years* now. Maybe the only thing that 
was left for them to decide resp. to convince them was a concrete plan 
  on how to procede (whereas my proposal is only to be seen as an 
intermediate step, of course our final goal is to provide unstripped 
sources and fully enabled libraries in Debian).

For the apps there should be no difference if the ffmpeg libraries are 
stripped or unstripped at build or run time, the API is just the same.
