From: Sakari Ailus Date: Wed, 21 May 2014 19:58:11 +0000 (-0300) Subject: [media] smiapp: Implement the test pattern control X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0e2a6b7f2b9303410c93fd4724f9d36ebc7be1c3;p=openwrt%2Fstaging%2Fblogic.git [media] smiapp: Implement the test pattern control Add support for the V4L2_CID_TEST_PATTERN control. When the solid colour mode is selected, additional controls become available for setting the solid four solid colour components.
