+<br />On Raspberry Pi 5, the actual supported image formats depend on the capabilities of the camera, not the list provided here.

+Note: For Raspberry Pi 5, the -d parameter needs to be added to all commands in this section to specify the subdev used for configuring parameters.
+
+For example, if executing ./media_setting_rpi5.sh or ./find_entity.sh prompts the use of /dev/v4l-subdev2 for parameter configuration, then <code>v4l2-ctl -L</code> should be changed to <code>v4l2-ctl -L -d /dev/v4l-subdev2</code>.
All the above functions can be implemented using [[Mv mipi i2c.sh user guide|mv_mipi_i2c.sh]].
