From 414fb90eae816e98d8b2d45a3dbce70f1dbc2064 Mon Sep 17 00:00:00 2001 From: Eino-Ville Talvala Date: Fri, 15 May 2015 11:10:29 -0700 Subject: Camera: Add new set video format/dataspace command This allows the video encoding subsystem inform the camera what format and dataspace should be used for metadata-mode buffers. This is necessary to allow software encoders and other generic consumers that cannot interpret HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED buffers.
