From 6a42d17668699234bfa2d459e29cc2732e59759b Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Mon, 23 Mar 2020 19:00:17 +0000 Subject: [PATCH] media: uapi: Add hevc ctrls for WPP decoding WPP can allow greater parallelism within the decode, but needs offset information to be passed in. Adds num_entry_point_offsets and entry_point_offset_minus1 to v4l2_ctrl_hevc_slice_params. This is based on Jernej Skrabec's patches for cedrus which implement the same feature.
