Subject: [pxc] Force EVEN/ODD fields?
Message-ID: <10pnvt8um74nqsukf0q585a7n5nkr5bgcb@4ax.com>

Hi,

I've finally gotten the courage and time to port all my code to use =
buffers. I
ported from 0.28 to 0.80.

It's working great.
:)

(With the exception of needing to rmmod all the existing Linux builtin =
video
driver modules before I load your pxc driver... a bit of a hassle that.)

=46rom what I could glean out of the documentation the capture is =
supposed to
always capture the same field to minimise jitter.

I don't seem to be getting even/odd fields exclusively, however. Rather I=
 get a
mix of the two.

I'm currently using mmap with buffer management, on a vanilla Mandrake =
8.1
installation. I have tried this with an Imagineation and generic 878. =
Both do
the same. Since I tend to switch my video signal between multiple =
unsynched
signals, I thought that this may be the problem. (I wait about 60 ms for =
the
card to re-sync after a switch).

My question is thus: Am I missing something to force only a capture of an=
 odd
or even field, or is the reason for me not being able to capture a =
consistent
field because I keep on switching? Is there some additional way I can =
ensure to
force my field?

an example would be appreciated...

Marius.
