[gentoo-user] video capture

[gentoo-user] video capture

[Matthew R. Lee]

I've been rumaging around on the internet for the last few hours, but I'm 
still confused ( a regular condition!)
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
Thanks
Matt

Does the camera generate a "normal" TV signal (PAL, SECAM, NTSC,...)? If so, 
the WinTV-PVR150 will work.

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"
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)?

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.

give it a whirl and let us know.

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
stuffage...."media" 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 


hth,

James

My experience is that most video capture devices are used for Home
Theater PC's, I've found the most information on the MythTV website.
You can check out the documentation on hardware at this link:
     http://www.mythtv.org/docs/mythtv-HOWTO-3.html#ss3.1

I use the Plextor ConvertX, you will find it mentioned under the "USB
Capture Devices" heading on the webpage above, with a link to the
website that has the open source linux driver.  This unit is nice
because all of the video encoding happens on the device, so I am able
to capture video with my ConvertX connected to a 400MHz Pentium 2
gentoo box.  Now the driver is available through portage.

See if you can get either the PX-M402U or the PX-TV402U in Chile.  I
do not think the PX-AV100U or the PX-TV100U will work with the open
source linux driver.

Right, after a lot more googling etc I might have found my solution.  The 
number of capture cards available here in Chile is limited.  I can't find any 
of the cards mentioned sofar,  Hauppauge for example is no where to be found 
in Chile.  The most widely available cards seem to be from Pinnacle.  The 
Pinnacle Dazzle DVC-90, according to the documentation with the kernel works 
with the video4linux em28xx driver.
I thought I should ask before I go buy it if anybody has experience with the 
card, or have I just volunteered to be the guinea pig :-)
