Hello everyones,
I am trying to integrate a camera inside weatherradio like said this section:
github.com/indilib/indi-3rdparty/blob/ma...adme-WeatherRadio.md
I am using:
a Raspberry Zero with raspbian buster os
a Raspberry Camera OV5647
Raspistill is working because i capture images with this instruction:
raspistill -ISO 100 -ss 1000 -v -o /usr/share/weatherradio/html/media/current_weather.jpg
"raspistill" Camera App (commit bab9bf8790cd Tainted)
Camera Name ov5647
Width 2592, Height 1944, filename /usr/share/weatherradio/html/media/current_weather.jpg
Using camera 0, sensor mode 0
GPS output Disabled
Quality 85, Raw no
Thumbnail enabled Yes, width 64, height 48, quality 35
Time delay 5000, Timelapse 0
Link to latest frame enabled no
Full resolution preview No
Capture method : Single capture
Preview Yes, Full screen Yes
Preview window 0,0,1024,768
Opacity 255
Sharpness 0, Contrast 0, Brightness 50
Saturation 0, ISO 100, Video Stabilisation No, Exposure compensation 0
Exposure Mode 'auto', AWB Mode 'auto', Image Effect 'none'
Flicker Avoid Mode 'off'
Metering Mode 'average', Colour Effect Enabled No with U = 128, V = 128
Rotation 0, hflip No, vflip No
ROI x 0.000000, y 0.000000, w 1.000000 h 1.000000
Camera component done
Encoder component done
Starting component connection stage
Connecting camera preview port to video render.
Connecting camera stills port to encoder input port
Opening output file /usr/share/weatherradio/html/media/current_weather.jpg
Enabling encoder output port
Starting capture -1
Finished capture -1
Closing down
Close down completed, all components disconnected, disabled and destroyed
My problem its with script camery.py that is in
/usr/share/weatherradio/bin the script said this:
#!/usr/bin/python3
#
# Script for shooting single images with automatic exposure adaption
# day and night..

When i run this script i got an error:
javier@raspberrypi:/usr/share/weatherradio $ ./bin/camera.py
Traceback (most recent call last):

Please, somebody can help me?
