Please see this thread for more details: http://www.mail-archive.com/linux-media@vger.kernel.org/msg52168.html This is about creating, selecting device configuration contexts and handling e.g. camera modes like viewfinder and still capture. Currently only mem-to-mem devices in V4L2 API are allowed to support multiple device contexts, and those are per file handle. I hope this clarifies it a bit for you. -- Regards, Sylwester
