oaCapture on Raspberry Pi

Posted on August 13, 2014 by james

I’ve finally done the (small amount of) work to get oaCapture working on the Raspberry Pi.  There genuinely wasn’t that much to do.  I was surprised how easily it all worked.  It does struggle to keep up with high frame … Continue reading →
