From 94cf90dae250a9dcb3b52b655a94e2106a422698 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Wed, 12 Feb 2014 11:18:20 +0000 Subject: [PATCH 169/196] V4L2: H264 profile & level ctrls, FPS control and auto exp pri Several control handling updates. H264 profile and level controls. Timeperframe/FPS reworked to add V4L2_CID_EXPOSURE_AUTO_PRIORITY to select whether AE is allowed to override the framerate specified.
