This page is using the default release RELEASE_SUMO_V1.0_DART-MX8M.
To view this page for a specific Variscite SoM and software release, please follow these steps:
- Visit variwiki.com
- Select your SoM
- Select the software release
Testing MIPI-CSI2 cameras
Before running any of the pipelines below make sure you have camera(s) connected. i.MX family of processors uses gstreamer as 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 the following output
# v4l2-ctl --list-devices i.MX6S_CSI (platform:30a90000.csi1_bridge): /dev/video0 i.MX6S_CSI (platform:30b80000.csi2_bridge): /dev/video1
As you can see above there are 2 cameras accessible as /dev/video0 and /dev/video1
Testing Camera Preview on Display
In the examples below /dev/videoX is either /dev/video0 or /dev/video1
- 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 /dev/videoX is either /dev/video0 or /dev/video1
- 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
Using both cameras simultaneously
The following pipeline is an example of using both cameras simultaneously.
In this example a short video stream from each camera is saved as an MJPEG-encoded AVI file.
# gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=100 ! video/x-raw,width=1920,height=1080 ! jpegenc ! avimux ! filesink location=./test0.avi \ v4l2src device=/dev/video1 num-buffers=100 ! video/x-raw,width=1920,height=1080 ! jpegenc ! avimux ! filesink location=./test1.avi
