Subject: minimum v4l2 api
Date: Thu, 13 Nov 2008 16:56:38 -0600 [thread overview]
Message-ID: <491CB0A6.9080509@personnelware.com> (raw)
Apparently vivi is messed up enough that maybe it makes sense to write a new
test driver.
What is the minimum interface a v4l2 driver could have?
Something like: it registers itself as /dev/videoN, and
QueryCaps returns nothing.
It does not return any image. (yeah ?)
It can be unloaded.
and anything else that someone thinks is required for a well behaved driver that
follows the spec.
The plan is to start with that, get it and my tester working in harmony, then
start adding things to both sides of the fence. I am thinking additional
features will be enabled via module parameters, so that it can always be dumbed
down back to it's minimum.
