[PATCH 0/6] Add new controls for CQ and Frame-skip

[Stanimir Varbanov]

Hello,

This is a new series which adds Constant quality and Frame skip std
controls. The series is combined from two other series [1] and [2].

Changes:
 * added Reviewed-by Hans tag in 1/6 and 3/6.
 * fixed typos in 6/6
 * rebased on top of media/master

regards,
Stan

[PATCH 1/6] media: v4l2-ctrls: Add encoder constant quality control

[Stanimir Varbanov]

From: Maheshwar Ajja <majja@codeaurora.org>

When V4L2_CID_MPEG_VIDEO_BITRATE_MODE value is
V4L2_MPEG_VIDEO_BITRATE_MODE_CQ, encoder will produce
constant quality output indicated by
V4L2_CID_MPEG_VIDEO_CONSTANT_QUALITY control value.
Encoder will choose appropriate quantization parameter
and bitrate to produce requested frame quality level.

[PATCH 3/6] media: v4l2-ctrl: Add frame-skip std encoder control

[Stanimir Varbanov]

Adds encoders standard v4l2 control for frame-skip. The control
is a copy of a custom encoder control so that other v4l2 encoder
drivers can use it.

[PATCH 4/6] venus: venc: Add support for frame-skip mode v4l2 control

[Stanimir Varbanov]

This adds support for frame-skip-mode standard v4l2 control in
encoder driver. The control is implemented based on the
combination of client selected bitrate-mode and frame-skip-mode.
Once The client selected bitrate-mode (constant or variable) and
the frame-skip-mode is not disabled we set variable framerate for
rate controller.
