From 2a75364d09b05f257f4cd1f718e06e0247eb1dd3 Mon Sep 17 00:00:00 2001 From: Keiichi Watanabe Date: Mon, 18 Jun 2018 03:58:53 -0400 Subject: [PATCH] media: v4l2-ctrl: Add control for VP9 profile Add a new control V4L2_CID_MPEG_VIDEO_VP9_PROFILE for VP9 profiles. This control allows selecting the desired profile for VP9 encoder and querying for supported profiles by VP9 encoder/decoder. Though this control is similar to V4L2_CID_MPEG_VIDEO_VP8_PROFILE, we need to separate this control from it because supported profiles usually differ between VP8 and VP9.
