Is there any other documentation that gives an overview of the steps it
takes to grab images from a tuner card?
I have found the following documentation
http://www.linuxhq.com/kernel/v2.3/doc/video4linux/API.html, which has been
very helpful, but it is a little terse (I know, I know, what do I expect for
free :)
Is the read() call grabbing an image based on the capture settings or based
on the frame buffer settings?
The problem I am having at this point is that my read(fd, buffer, bufsize)
call is "blocking". It never returns...no error, no nothing. I set the
size of the buffer equal to the width*height*(depth/2) found in framebuffer.
That seems correct to me. I set the framebuffer base to 0 to prevent the
tuner from directly writing to my video card (I just want to capture images,
not display them).
I realize I am probably going about this all wrong, but I don't know where
to find example programs, documentation, etc...
Thanks in advance,
