I suggest you lift that NAK.
If you do i would apply this set of bugfixes and after that
look into, if its possible to factorize the SDR code out.
I first would do so within the same lib but once its more
seperated, maybe we can seperate the SDR code and move it
into a seperate libavradio leaving the input device/demuxer
as a user of that lib.
That would be a seperate lib and API used by a module
in libavdevice/libavformat as it was suggestes by jb
I dont know how well that refactorization would work out. I may
have looked at this from the wrong side
but as long as you block this patchset the code is stuck in
libavformat and libavdevice
thx
