Rpi CSI Camera usage

[Mikerr]

So now the v1.3 camera works with tinkerOS 2.03

view preview with this:

Code:

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=NV12,width=640,height=480 ! videoconvert ! autovideosink

For single images, initially I just got black images - but the camera needs some setup time, so this discards the early frames: 

Code:

gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=5 ! video/x-raw,format=NV12,width=640,height=480 ! videoconvert ! jpegenc ! multifilesink location=test.jpg

Code:

gpicview test.jpg

I've generalised that into a bigger script camstill.sh so you can do:

Code:

./camstill.sh -e jpeg -w 1280 -h 800

or for PNG format:

Code:

./camstill.sh -e png -f test.png

text overlay

Code:

./camstill.sh -t "Experiment 13"

All the camera scripts are at http://github.com/mikerr/tinkercam


Other apps don't seem to able to access the camera via V4lL: /dev/video0 shows up and called rkisp10_ispdev but apps won't access it ?
