memory leak
hello
having issues with (broken down to suspected code)
device = GPhoto2::Camera.first
data = device.preview.data
leaks - i call the data = device.preview.data in a loop - to get a updated preview - works - but seems that memory is leaking
how can i check and verify that this is called
actual code:
while true
sleep 0.5
@mutex.synchronize do
file = device.preview
self.preview = file.data
end
if shutdown
break
end
end
if i remove the device.preview - and do self.preview="123" the leak is gone.
regards
helmut
ffi-gphoto2 gem not working when bundled and used in Sinatra/Rails app
Great gem! I can only seem to use it in one off ruby scripts though. When I include it in a Gemfile for a Rails or Sinatra app, bundle install and require 'gphoto2' I am met with the following error:
.rvm/gems/ruby-2.1.2/gems/ffi-gphoto2-0.5.0/lib/ffi/gphoto2_port.rb:3:in `module:GPhoto2Port': uninitialized constant FFI::Library (NameError)
Any thoughts?
reset camera
i would love to get a Camer.reset, wich does a usb reset, like gphoto2 --reset
(as sometimes the cam hang's)
the required C code
GPPort *port;
GPPortInfo info;
/* If a camera is already open, close it, as we need a new port */
if (gp_params.camera) {
gp_camera_exit (gp_params.camera, gp_params.context);
/* exit, not free. will reopen on next command. */
}
params->p.r = gp_port_new (&port);
if (params->p.r != GP_OK) {
gp_log(GP_LOG_ERROR,"port_reset", "new failed %d", params->p.r);
break;
}
params->p.r = gp_camera_get_port_info (gp_params.camera, &info);
if (params->p.r != GP_OK) {
gp_log(GP_LOG_ERROR,"port_reset", "camera_get_port_info failed");
break;
}
params->p.r = gp_port_set_info (port, info);
if (params->p.r != GP_OK) {
gp_log(GP_LOG_ERROR,"port_reset", "port_set_info failed");
break;
}
params->p.r = gp_port_open (port);
if (params->p.r != GP_OK) {
gp_log(GP_LOG_ERROR,"port_reset", "open failed %d", params->p.r);
break;
}
params->p.r = gp_port_reset (port);
gp_port_close (port);
gp_port_free (port);
actually i have no clue of the ffi stuff, could you help me with it?
Calling save fails when setting iso, shutterspeed2 or f-number
I can set some configuration keys like imagesize and imagequality then call camera.save and camera.capture just fine. But when I try to set configuration for iso and call camera.save I get an Unspecified error (-1). And when I try to set configuration for shutterspeed2 or f-number and call camera.save I get an Unsupported operation (-6).
This works:

First, thanks for this gem.
I'm seeing a lot of errors with the latest libgphoto2. Any interest in updating things? (I would be willing to throw a little money behind a bug bounty if you wanted ($200?))
Thanks!
