Interesting, I'm assuming this only works with hauppage pvr cards? ?
What does a file read on /dev/video do for ordinary cards?
Is the format parsable?
cat /dev/video0 does manage to completely corrupt my ssh window beyond
even a 'reset' ;p
On a more serious note I was thinking of eventually making a gpl library
for Labview for manipulating video. If I can just do a read of that
'file' and run it through a function or what not to extract it out to
RGB or YUV, then it would likely be enough. (Note that Labview is a
visual programming language some scientists and engineers like.)
If would of course have to use existing linux code. Of course there
isn't a high demand for this, but it might be nice for some people who
would need it to have an alternative to the expensive national
instruments package. Of course this is getting off topic..
