Subject: [PATCH 2/4] venus: venc: Add support for frame-skip mode v4l2 control
Date: Sun, 5 Jul 2020 15:11:26 +0300 [thread overview]
Message-ID: <20200705121128.5250-3-stanimir.varbanov@linaro.org> (raw)
In-Reply-To: <20200705121128.5250-1-stanimir.varbanov@linaro.org>
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.
