Comment(by Carlos Azevedo <geral@…>):
As requested via IRC, I'm adding a quote from
http://www.mythtv.org/wiki/ALSA,_BTTV_and_MythTV_0.22, which a wrote at
the time:
"Everytime I tried to use the board for capture MythTV would error out
about not being able to set the sample rate (wanted 48000, the driver
reported 119466 sp/s), not being able to set the number of channels
(wanted two, the driver only reported one) and some other errors"
I never got around to debugging the interaction of the MythTv's
initialization code with ALSA, I simply looked at the code for arecord
that does the same initialization in a much simplified mannor, plugged it
in and it worked. I don't understand why the current code does it in such
a roundabout way, but my way does work, and should work with all BTTV-
based setups. Setups with others kinds of capture cards may require that
kind of initialization but I doubt it.
P.S. This patch has to be applied inside libs/libmythtv
