What my patch is doing is adding support for AM demodulation, the AM
specific code is like 2 pages. The future plan for FM demodulation will
not add alot of code either. DAB/DVB should also not be anything big
(if that is implemented at all by anyone)
If the code grows beyond that it could be split out into a seperate
library outside FFmpeg.

The size of all of SDR really has as much bearing on FFmpeg as the size
of all of mathematics has on the use of mathematics in FFmpeg.

Lets see where the review process leads to.
It is possible iam missing some things, its possible others are missing
some factors.
Ultimately sdr is more similar than it is different from existing input
devices and demuxers.
The review process may identify possible solutions that benefit other
input devices too. It might identify shortcommings in FFmpeg that
could lead to improvments.
I dont really enjoy the review process ATM, no ;) but lets see where it
leads to.

Thx
