Subject: utils: media-ctl: Set V4L2_MBUS_FRAMEFMT_SET_CSC flag to set colorspace Author: Laurent Pinchart <laurent.pinchart+rene...@ideasonboard.com> Date: Tue Apr 8 18:46:45 2025 +0300 When setting colorspace fields on a source pad, the V4L2 subdev API requires setting the V4L2_MBUS_FRAMEFMT_SET_CSC flag. This is missing in libv4l2subdev, resulting in colorspace fields being ignored for source pad. Fix it by setting the flag.
