EVT Camera Driver Example Software

[mrawding]

Hello,

I am trying to spin up a ROS2 node to run the single camera on the EVT board. Are there any software packages and/or source code available to interface with the single camera on the EVT?

Hi @mrawding ,

Not much just right now but in the next week or two we'll have some public facing camera code up.

Hi Travis,

Any update on the public facing code? It would be great if there is a gstreamer example on how to interface with the /dev/rb5-camera* pipes and get the frame data.

From what I gathered, it looks like the rb5-camera-server is using the camx API + gstreamer instead of HAL3 and Camera3 API like it does on the voxl.

Hi @mrawding ,

The current early release on the EVT hardware relies on gstreamer.... for example:

cd /data/misc/camera
rm *

gst-launch-1.0 -e qtiqmmfsrc camera=0 name=tracker ! video/x-h264,format=NV12,width=640,height=480,framerate=30/1 ! queue ! h264parse ! avdec_h264 ! videoconvert ! pngenc ! multifilesink enable-last-sample=false location="/data/misc/camera/cam0_img_%d_.png"

This will save images to the path specified. We're actively working on getting the same interfacing as VOXL up on this ;). Next few weeks should have some good PUBLIC REPO updates.
