Warning: This page is designed to be used with a 'release' URL parameter.
This page is using the default release RELEASE_DUNFELL_V1.0_VAR-SOM-MX7.
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
VAR-SOM-MX7 - Camera
Testing our MIPI cameras
Camera probe
Make sure the camera is connected, and boot the board.
Then, run the below command to verify the camera was detected successfully:
# v4l2-ctl --list-devices
This should output below
i.MX6S_CSI (platform:30710000.csi):
/dev/video1
pxp (pxp_v4l2_out):
/dev/video0
In the output seen above, "i.MX6S_CSI" is the camera, and "pxp" is the i.MX Pixel Processing Pipeline.
i.MX platform specific gstreamer plugins
Run below command to verify you have the i.MX7 platform specific gstreamer plugins installed on your system:
# gst-inspect-1.0 | grep "imx" imxpxp: imxpxpvideotransform: Freescale PxP video transform imxpxp: imxpxpvideosink: Freescale PxP video sink imxv4l2videosrc: imxv4l2videosrc: V4L2 CSI Video Source imxaudio: imxmp3audioenc: Freescale i.MX MP3 encoder imxaudio: imxuniaudiodec: Freescale i.MX uniaudio decoder
Gstreamer example 1: Testing Camera Loopback / Camera preview on the display
The below pipelines are suitable for the fslc based Yocto releases for the VAR-SOM-MX7 (Yocto Morty and newer).
- For 640x480@30fps:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 imx-capture-mode=0 ! imxpxpvideosink
- For 720x480@30fps:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 imx-capture-mode=1 ! imxpxpvideosink
- For 1280x720@30fps :
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 imx-capture-mode=2 ! imxpxpvideosink
- For 1920x1080@30fps:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 imx-capture-mode=3 ! imxpxpvideosink
- For 2592x1944@15fps:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 imx-capture-mode=4 ! imxpxpvideosink
Gstreamer example 2: Taking a JPEG snapshot from the camera
To capture and encode a JPEG snapshot from the camera, run one of the below pipelines depending on the wanted resolution:
- For 640x480:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 num-buffers=1 imx-capture-mode=0 ! 'video/x-raw,format=UYVY' ! jpegenc ! filesink location=/tmp/test.jpg
- For 720x480:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 num-buffers=1 imx-capture-mode=1 ! 'video/x-raw,format=UYVY' ! jpegenc ! filesink location=/tmp/test.jpg
- For 1280x720:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 num-buffers=1 imx-capture-mode=2 ! 'video/x-raw,format=UYVY' ! jpegenc ! filesink location=/tmp/test.jpg
- For 1920x1080:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 num-buffers=1 imx-capture-mode=3 ! 'video/x-raw,format=UYVY' ! jpegenc ! filesink location=/tmp/test.jpg
- For 2592x1944:
# gst-launch-1.0 imxv4l2videosrc device=/dev/video1 num-buffers=1 imx-capture-mode=4 ! 'video/x-raw,format=UYVY' ! jpegenc ! filesink location=/tmp/test.jpg
