EXC_BAD_ACCESS from Canon's EDSDK EdsInitializeSDK() API

由 时光怂恿深爱的人放手 提交于 2019-12-11 11:07:03
问题 I'm writing a camera control program in Xcode 7.2 on OS X 10.11.2 and every once and a while my program will crash at EdsInitializeSDK(). Most of the solutions online suggest downloading other EDSDK.framework file, but this hasn't worked for me. Also, most of the solutions were written almost 3 years ago. The thing that doesn't make sense to me is that the program runs most of the time and only occasionally crashes. Has anyone found a work around to prevent the bad access? 回答1: This seems to

EDSDK callbacks not working

问题 I have a working command line application, using EDSDK v2.13. However, when I register callbacks, there is a burst of property events then nothing. I have remedied this a loop like this: while(!_kbhit()) { EdsOpenSession(camera); Sleep(10); EdsCloseSession(camera); } This seems horribly kludgy. Is the SDK broken, or am I missing something? 回答1: If you're using the EDSDK on Windows, you have to have a Windows message loop in your main thread, otherwise callbacks won't happen. (This is because

问题 I download the source only tutorial here. When I run it with connect my Canon 70D, I got the error below. What is the point I missed? The Error: The error occurs on this line: And here is how the folder which includes EXE file looks like: 回答1: I fixed this problem by letting the camera know there's enough disk space on the host. Adding the line CameraHandler.SetCapacity(); before CameraHandler.TakePhoto(); should do the trick. 回答2: Error 0x8D07 stands for EDS_ERR_TAKE_PICTURE_CARD_NG I'm not

Canon LiveView: image convertion to OpenCV Mat

I use example from Canon EDSDK and all was ok until this part of code: // // Display image // I googled a lot of examples but all of them was written on C# or MFC or VB. Also I found advise to use libjpegTurbo for decompressing image and then showing it using opencv. I tried to use libjpegTurbo but failed to

take picture and directly save image to pc using edsdk 2.8

由 ◇◆丶佛笑我妖孽 提交于 2019-12-06 13:13:51
I'm new to the EDSDK 2.8 At the moment, my program can take pictures. However, when a picture is taken, that picture is temporarily stored in a buffer in the Canon camera. I would like to know how to save it directory to the PC? Does anyone have any ideas? Or sample code in c# or vb.net? Here is what I have done: First, you have to register for the callback event when an object is created (ie, a picture). I did this in a registerEvents method that I created: // Register OBJECT events edsObjectEventHandler = new EDSDK.EdsObjectEventHandler(objectEventHandler); error = EDSDK
