Subject: Query: Mutiple CAPTURE ports on a single device
Date: Wed, 12 Mar 2014 17:58:24 -0000	[thread overview]
Message-ID: <04588cf620ba3635c9a59e6eb92d0000.squirrel@www.codeaurora.org> (raw)

Hi

I have a v4l2 driver for a hardware which is capable of taking one input
and producing two outputs. Eg: Downscaler which takes one input @ 1080p
and two outputs - one @ 720p and other at VGA. My driver is currently
implemented as having two capabilities -

1. V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE
2. V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE

Do you know if I can have two CAPTURE capabilities. In that case how do I
distinguish between QBUF/DQBUF of each capability?

Thanks
Vinay
