And DSP belongs in DSP projects, mpeg decoding belongs in libmpeg2
png, ogg, vorbis belong in their respective projects
in fact FFmpeg shouldnt exist we should all have been contributing to
gstreamer

Wouldnt that be the same line of thought ?

But seriously there are 2 things.
Theres myself and what is fun for me to work on (you suggest i shouldnt have fun?)
And there is FFmpeg that is missing any and all SDR support

Are you planing to add SDR support through some library like GNU radio
to FFmpeg ?
I think GNU radio is a poor choice, even just the base package has
"Installed-Size: 407 MB" that would be huge dependancy to avoid ATM 2 pages
of modem code, also GNU Radio is not LGPL, i think FFmpeg generally prefers
LGPL over GPL. Not that i personally have anything against GPL, I like GPL
but thats not the preferred license in FFmpeg

do you suggest we should create a libavradio ?
or can you suggest an existing library that would fit the C + clean ASM
LGPL style that FFmpeg tends to prefer ?

thx
