DART-MX8M CSI

DART-MX8M-MINI Camera

Testing MIPI-CSI2 cameras

Before running any of the pipelines below make sure you have camera(s) connected.
The i.MX family of processors uses gstreamer as a multimedia framework. Please refer to https://gstreamer.freedesktop.org/.

Camera Probe

Run the following command to see if you have the camera(s) detected:

# v4l2-ctl --list-devices

This should produce an output similar to this:

# v4l2-ctl --list-devices
i.MX6S_CSI (platform:32e20000.csi1_bridge):
      /dev/video0

In the example above, you can see there is 1 camera accessible as /dev/video0

Testing Camera Preview on Display

In the examples below, replace /dev/videoX with an actual camera device, following the Camera Probe section.

• VGA 480p 640x480@30fps:

# gst-launch-1.0 v4l2src device=/dev/videoX ! video/x-raw,width=640,height=480 ! autovideosink sync=false

• NTSC 480p 720x480@30fps:

# gst-launch-1.0 v4l2src device=/dev/videoX ! video/x-raw,width=720,height=480 ! autovideosink sync=false

• HD 720p 1280x720@30fps:

# gst-launch-1.0 v4l2src device=/dev/videoX ! video/x-raw,width=1280,height=720 ! autovideosink sync=false

• Full HD 1080p 1920x1080@30fps:

# gst-launch-1.0 v4l2src device=/dev/videoX ! video/x-raw,width=1920,height=1080 ! autovideosink sync=false

• QSXGA 1944p 2592x1944@15fps:

# gst-launch-1.0 v4l2src device=/dev/videoX ! video/x-raw,width=2592,height=1944 ! autovideosink sync=false

Testing Camera JPEG Snapshot

To capture JPEG snapshot run one of the pipelines below depending upon the required picture resolution.

In the examples below, replace /dev/videoX with an actual camera device, following the Camera Probe section.

• VGA 480p 640x480:

# gst-launch-1.0 v4l2src device=/dev/videoX num-buffers=1 ! video/x-raw,width=640,height=480 ! jpegenc ! filesink location=/tmp/test_640x480.jpg

• NTSC 480p 720x480:

# gst-launch-1.0 v4l2src device=/dev/videoX num-buffers=1 ! video/x-raw,width=720,height=480 ! jpegenc ! filesink location=/tmp/test_720x480.jpg

• HD 720p 1280x720:

# gst-launch-1.0 v4l2src device=/dev/videoX num-buffers=1 ! video/x-raw,width=1280,height=720 ! jpegenc ! filesink location=/tmp/test_1280x720.jpg

• Full HD 1080p 1920x1080:

# gst-launch-1.0 v4l2src device=/dev/videoX num-buffers=1 ! video/x-raw,width=1920,height=1080 ! jpegenc ! filesink location=/tmp/test_1920x1080.jpg

• QSXGA 1944p 2592x1944:

# gst-launch-1.0 v4l2src device=/dev/videoX num-buffers=1 ! video/x-raw,width=2592,height=1944 ! jpegenc ! filesink location=/tmp/test_2592x1944.jpg
