Subject: Any USB chip that delivers 60fps?
Date: Tue, 27 May 2014 21:47:36 -0400 [thread overview]
Message-ID: <53854038.1020305@nrdvana.net> (raw)
Hi, I'm looking for any USB-connected device that can give me 60fps from
a NTSC signal. I'm either looking for a chip+driver that support
V4L2_FIELD_ALTERNATE (which I gather are rare) so that I can construct
my own frames at 60Hz by blending each pair of neighboring fields, or
ideally, to find hardware or driver that does a good job of it for me.
Why NTSC you ask? because I can find high quality cameras that work
great in low-light scenarios, where most USB cameras fall flat.
And as a follow-up question, is it possible and how hard would it be to
add V4L2_FIELD_ALTERNATE support to one of the EasyCap drivers? Does the
hardware de-interlace the frames on its own or is that in software?
Thanks,
-Mike
