libavdevice does depend on libavfilter but it does not depend on
lets say libpostproc

if for example you upgrade libavfilter.so and the new version no
longer depends on libpostproc.so you still would have libavdevice.so
depening on it if iam not mistaken
that is after the patch but not before

iam not sure anything is braindead, its just the result of a the
axioms/choices taken

Not putting AVFrame in AVBuffer/AVPacket within the existing
high level framework
-> this results in the usecase in transcoding tools being very messy
-> so a seperate test program is used
and this testprogram is placed in libavdevice directory
and noone did something like that before it seems which uncovers
that the build systems has problems with complex recursive dependancies

not sure how to best fix this ...
