[PATCH v3 0/3] Add controls for VP8/VP9 profile

[PATCH v3 0/3] Add controls for VP8/VP9 profile

[Keiichi Watanabe]

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.

[PATCH v3 1/3] media: v4l2-ctrl: Change control for VP8 profile to menu control

[Keiichi Watanabe]

Add a menu control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile and
make V4L2_CID_MPEG_VIDEO_VPX_PROFILE an alias of it. This new control
is used to select a desired profile for VP8 encoder, and query for
supported profiles by VP8 encoder/decoder.

Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name
contains 'VPX', it works only for VP8 because supported profiles usually differ
between VP8 and VP9. In addition, this contorol cannot be used for querying
since it is not a menu control but an integer control, which cannot return an
arbitrary set of supported profiles.

The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with
controls for other codec profiles. (e.g. H264)

In addition, this patch also fixes the use of
V4L2_CID_MPEG_VIDEO_VPX_PROFILE in drivers of Qualcomm's venus and
Samsung's s5p-mfc.

[PATCH v3 2/3] media: v4l2-ctrl: Add control for VP9 profile

[Keiichi Watanabe]

Add a new control V4L2_CID_MPEG_VIDEO_VP9_PROFILE for VP9
profiles. This control allows to select a desired profile for VP9
encoder and query 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.

> Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name
> contains 'VPX', it works only for VP8 because supported profiles usually differ
> between VP8 and VP9. In addition, this contorol cannot be used for querying

typo: contorol -> control

> since it is not a menu control but an integer control, which cannot return an
> arbitrary set of supported profiles.
> 
> The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with
> controls for other codec profiles. (e.g. H264)
> 
> In addition, this patch also fixes the use of
> V4L2_CID_MPEG_VIDEO_VPX_PROFILE in drivers of Qualcomm's venus and
> Samsung's s5p-mfc.
