I am making an android app in java that can do bulb capture, it's not using libgphoto2, but instead using the hex codes the cameras support. The problem is the Canon EDSDK documentation does not give the hex values the camera needs for EosRemoteRelease full press, half press, etc.
How does libgphoto2 send this information to the camera? Is it a hex value or something else? This is how what I'm trying to do is done with gphoto2: gphoto2 --wait-event=2s --set-config eosremoterelease=Immediate --wait-event=5s --set-config eosremoterelease=Off This is how I'm doing it in my java app: EosRemoteReleaseOn = 0x9128; sleep.500ms EosRemoteReleaseOff = 0x9129; However it is doing nothing. I think because I am not passing the "immediate" value to the camera over USB PTP. However, I cannot simply pass it to the camera as "immediate", there must be a numerical value for it. Where in gphoto2 can I find this numerical value? I searched the entire codebase for gphoto2 but can't find where this is handled at all. And when you set this in gphoto2: set-config bulb=1 set-config bulb=0 What is that changing? Where is it located? How is it affecting the PTP Hex Codes being sent to the camera? -- View this message in context: http://gphoto-software.10949.n7.nabble.com/EOS-PTP-HEX-codes-for-Bulb-and-EosRemoteRelease-Is-there-a-way-of-finding-them-tp16816.html Sent from the gphoto-devel mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Gphoto-devel mailing list Gphoto-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gphoto-devel
