Subject: [PATCH v3 0/3] Add controls for VP8/VP9 profile
Date:   Thu, 14 Jun 2018 16:46:49 +0900
Message-Id: <20180614074652.162796-1-keiichiw@chromium.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch series add new menu controls V4L2_CID_MPEG_VIDEO_VP8_PROFILE and
V4L2_CID_MPEG_VIDEO_VP9_PROFILE for VP8/VP9 profiles. These controls can be used
to select a desired profile for VP8/VP9 encoders. In addition, they are also
used to query for supported profiles by an encoder or a decoder.

Patch 1 adds a control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile. Though
V4L2_CID_MPEG_VIDEO_VPX_PROFILE is originally used for VP8 profile, this control
is not good by the following reasons:
(i) Despite the name contains 'VPX', it cannot be used for VP9 because supported
profiles differ between VP8 and VP9.
(ii) Unlike other controls for profiles (e.g. H264), this is not a menu control
but an integer control, which cannot be used to query for supported profiles.

Thus, V4L2_CID_MPEG_VIDEO_VPX_PROFILE is deprecated and become an alias of
V4L2_CID_MPEG_VIDEO_VP8_PROFILE. In addition, Patch 1 fixes the use of
V4L2_CID_MPEG_VIDEO_VPX_PROFILE in existing venus/s5p_mfc drivers.

Patch 2 adds a control V4L2_CID_MPEG_VIDEO_VP9_PROFILE for VP9 profile.

By patch 3, this control is supported in MediaTek decoder's driver, which
supports VP9 profile 0.

Version 3 changes:
- Add V4L2_CID_MPEG_VIDEO_VP8_PROFILE in v4l2-controls.
- Make V4L2_CID_MPEG_VIDEO_VPX_PROFILE to be an alias of
  V4L2_CID_MPEG_VIDEO_VP8_PROFILE.
- Fix the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in venus/s5p_mfc drivers.
- Small fix in mtk_vcodec_dec.

Version 2 changes:
- Support V4L2_CID_MPEG_VIDEO_VP9_PROFILE in MediaTek decoder's driver.

Version 1 changes:
- Add V4L2_CID_MPEG_VIDEO_VP9_PROFILE in v4l2-controls.
