I wrote gr-cxadc which is a gnuradio wrapper to use the cxadc driver
from any gnuradio script, just like the gr-usrp does for the usrp.
So you don’t need to capture to file first anymore.
I also wrote some example scripts which work fine (including GUI).
I haven’t implemented tuning yet, because we need a mor general approach
for the different tuners out-there.
(Maybe use the way this is done in v4l drivers)
For now I just hooked the IF-output of my TVRX to the video-input of the
cx2388xx TV-tuner card.
(I then can tune the TVRX tuner using the usrp, but all the capturing is
done using the tv-card / cxadc)
