Here's my problem. I have a video camera (ken-a-vision, 7000 series)
which I can attached to my microscope which outputs a standard analog
signal. I want to capture this signal on my laptop and edit the video.
What I need is a basic external video capture card that will work with
linux. Any suggestions. Sound and colour are irrelevant as the 'stars'
of the videos are both dead and transparent
Does the camera generate a normal TV signal (PAL, SECAM, NTSC,...)? If
so, the WinTV-PVR150 will work.
Most likely it has a standard 'RCA' style connector, which should just
connect up to the (yellow) rca connextor on your tv. Try that to see if
you get an image. I do not know if Chile uses ntsc/pal/secam as it's
standard, but for for traditional tv monitors are usually one of those three.
I assume so, the manual doesn't explicitly say so, but it says just connect
it
to a video recorder or tv and away you go
give it a whirl and let us know.
A quick google and check of my usual computer suppliers here in Chile doesn't
bring up that card. Does it belong to a generic type? Will the average
TVtuner type card work along with video4linux ( I guess)?
The last time I purchased a plain old video (ntsc/pal) input card, I just
looked under '/usr/src/linux' until I found the dir with all of the video
stuffagemedia or video are keyword, I think.
One of the files actually listed all of the cards and showed which kernel
drivers covered which grouops of cards. Sorry, I do not remember more
specifically, besides those sorts of things get 're_arranged' under
the kernel and support for any gven card can be dropped or added, depending
on the politics at kerenel.org.
A quick parse reveals this dir:
/usr/src/linux/drivers/media/video
Get use to looking at the source code files as the comments in the various
drivers are often wonderfully full of enlightenment. REMEMBER video on
linux is a 'work in progress'.
The bt8xx is an excellent dir to poke around in. Start with this file:
/usr/src/linux/drivers/media/video/bt8xx/bttv-cards.c
