Absolute quickest video capture

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hey again, thanks for the help on the channel stuff, I ended up using
VIDIOC_S_FREQ, and cutting a ton of stuff out of frequency.[hc] from
xawtv.  Works fine now.

Second off, what exactly is the quickest way to capture stuff from the
card.  I notice that xawtv uses preview (at least as much as I can tell
from breakpoints and from the -v 2 option), is this the fastest way to get
data from the card (bt878)?  And if so, why is that? I would have thought
that the streaming interface would be the absolute fast way to get stuff
out.  Anyway, thanks a lot, Chris
