-## Camera setup on RPi4
-
-This assumes that you'll be using the Raspberry Pi Camera Module, which can
-easily hooked on the board using the LVDS connector. Further more information
-about how to connect it, could be found at
-[Installing a Raspberry Pi camera](https://www.raspberrypi.com/documentation/accessories/camera.html#installing-a-raspberry-pi-camera)
-
-With the camera installed, you'll need to enable it by editing /boot/config.txt
-file (if you're booting an AGL image over a sd-card it will be there by
-default, otherwise -- in case of doing netboot, you'll have to create
-manually) and add the following entry:
-
-
- ## start_x
- ## Set to "1" to enable the camera module.
- ##
- ## Enabling the camera requires gpu_mem option to be specified with a value
- ## of at least 128.
- ##
- ## Default 0
- ##
- start_x=1
-
-And reboot your device. Afterwards, after logging it, make sure that you have
-the /dev/video0 device created. You could also use v4l2-ctl to verify
-that is indeed usable as a capture device:
-
- $ v4l2-ctl -d /dev/video0 --all
-
-In order to test out video playback, use the following gstreamer pipeline:
-
- $ gst-launch-1.0 v4l2src device=/dev/video0 ! \
- video/x-raw,width=640,height=480 ! waylandsink fullscreen=true
-
-Alternatively, using [camera-gstreamer](https://gerrit.automotivelinux.org/gerrit/gitweb?p=apps/camera-gstreamer.git;a=summary)
-application could might be another possibility, but you'll have to build it
-yourself and add it in the image.
-
-This includes an example on how to create a xdg-toplevel surface and create a
-gstreamer pipeline, instead of relaying on waylandsink to create one for you,
-in a programmatic fashion.
-
-## Display setup on RPi4
-
-This assumes that you'll be using the Raspberry Pi 7'' display. Installation
-can be found at [Rpi Display page](https://www.raspberrypi.com/documentation/accessories/display.html).
-
-If booting over the network, the dtb should already contain the ft5406 dtb,
-while booting over sd-card the following show be in the /boot/config.txt
-file:
-
- dtoverlay=rpi-ft5406-overlay
-
-Once the board boots up, you should get a rainbow like effect and afterwards
-booting up would display debug scrolling over. You'll need to adjust the
-orientation as the 800x480 is in portrait. Edit /etc/xdg/weston/weston.ini and
-add a new output entry, like the following:
-
- [output]
- name=DSI-1
- transform=90
-
-Note that for the Qt platform, the homescreen application, together with the
-other demo applications, is tailored specifically for a 1080p display and it
-will display incorrectly on such a smaller display.
-
-## Testing out video camera without a real device
-
-While the above requires having a real video camera device, one can use out
-the [vivid module](https://docs.kernel.org/admin-guide/media/vivid.html?highlight=vivid#the-virtual-video-test-driver-vivid)
-to try out your custom application or just testing out camera functionality in AGL.
-
-You should normally have the module present, not loaded, for either **rpi4** or for
-**h3ulcb** boards. Load the module, like in the following command:
-
- modprobe vivid allocators=0x1
-
-Have a look at the kernel ring buffer to see what capture devices are created
-and use as source:
-
- $ gst-launch-1.0 v4l2src device=/dev/videoXX ! \
- video/x-raw,width=640,height=480 ! waylandsink fullscreen=true
-
-making sure to replace /dev/videoXX with correct capture device. You can check
-that easily using the v4l2-ctl mentioned above.
-
-Note that using camera-gstreamer will attempt to find the first available
-capture device, so if you happen to have to another one before the one created
-by this module it might not work. You can bypass that, by just making a symlink
-from /dev/videoXX to /dev/video0 to make first available capture device.
