i'm running gphoto2 on a Linux Raspberry Pi, waiting for a photo to be taken on a Canon EOS 1200D which is connected to the RPi via a USB cable. Most of the time (every once in a while it does work), it seems that the photo capture event isn't firing or gphoto2 isn't detecting it. When I take a photo it says this:
UNKNOWN PTP Property d107 changed UNKNOWN FocusInfo eosversion=0,size=5184x3456,size2=5184x3456,points={{0,743,117,181},{-839,393,172,129},{839,393,172,129},{-1394,0,172,129},{0,0,224,222},{1394,0,172,129},{-839,-393,172,129},{839,-393,172,129},{0,-743,117,181}},select={},unknown={10000000ffff} UNKNOWN PTP Property d108 changed UNKNOWN PTP Property d1b8 changed UNKNOWN PTP Property d1b7 changed UNKNOWN PTP Property d1b0 changed UNKNOWN PTP Property d107 changed UNKNOWN FocusInfo eosversion=0,size=5184x3456,size2=5184x3456,points={{0,743,117,181},{-839,393,172,129},{839,393,172,129},{-1394,0,172,129},{0,0,224,222},{1394,0,172,129},{-839,-393,172,129},{839,-393,172,129},{0,-743,117,181}},select={},unknown={10000000ffff} UNKNOWN PTP Property d108 changed UNKNOWN PTP Property d1b8 changed UNKNOWN PTP Property d104 changed UNKNOWN PTP Property d104 changed
So it seems that the focus event is being detected, but not the actual capturing of the photo.
This is my command:
gphoto2 --filename "%y%m%d%H%M_1.%C" --debug --debug-logfile="/home/user1/gphoto-debug.txt" --capture-tethered
though when I do --capture-image-and-download it does work, the photo is taken and downloaded to the computer, but my camera is being triggered by a sensor so it can't be gphoto triggering it.
This is the content of the --debug-logfile:
