[Bug 35780] New: unhandled exception; qcap; while running cura.py
http://bugs.winehq.org/show_bug.cgi?id=35780 Bug ID: 35780 Summary: unhandled exception; qcap; while running cura.py Product: Wine Version: 1.6.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: blocker Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: jluscher(a)gmail.com Created attachment 47775 --> http://bugs.winehq.org/attachment.cgi?id=47775 backtrace file from wine at crash Running Cura (for 3D printing - developed in Python). Cura is running very well under wine 1.6; manipulating models in 3D, slicing the models into GCode, saving the GCode to disk, etc. Linux detects the attachment of the USB cable to the printer controller (Marlin) at 'ttyUSB0', and Cura also acknowledges the connection has been made - it changes a button of the GUI from 'slice' to 'print'. When I click on 'print' a window is opened and at the same time another is opened from wine reporting a crash (backtrace attached). I have searched for something called 'qcap' which, to me, appears to be the last code being run - but I can find nothing on it. I am running Cura 14.01 from website: http://software.ultimaker.com/ James Luscher -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=35780 --- Comment #1 from James Luscher <jluscher(a)gmail.com> --- More research indicated that the crash was related to accessing the webcam. I have an image (.png) of the details here: http://ubuntuone.com/26EJrLnsjM9NxS4FbbrJIq The developer has responded that the next revision of Cura (14.02) is going to remove access to the webcam. I will try the new version ASAP, which will hopefully, let me proceed with running the program - though it doesn't mean that any problem has been fixed :-( James -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=35780 --- Comment #3 from James Luscher <jluscher(a)gmail.com> --- Further research shows Cura makes use of a Python VideoCapture module for windows documented at: http://videocapture.sourceforge.net/ The comments for videocapture refer to this Windows tech: "The low-level module uses DirectShow which is already included in DirectX 8.0 and higher."

It attempts to use the camera as the initial filter and a sample grabber as the intermediate filter, and expects the sample grabber to connect to the default renderer: hr = self->ob_pBuilder->RenderStream( &PIN_CATEGORY_CAPTURE, // changed from ..._PREVIEW to ..._CAPTURE &MEDIATYPE_Video, self->ob_pSrc, // src pF, // via NULL // dest ; or pNullRenderer ); if (FAILED(hr)) { PyErr_SetString(VidcapError, "Capture Graph could not be created."); cleanup(self); return FALSE; } (self->ob_pSrc = camera, pF = sample grabber) This fails on Wine, in all 3 of the examples that come with VideoCapture-0.9.5.

It should be able to; I accidentally broke the sample grabber in some ways recently. I have some patches. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

https://bugs.winehq.org/show_bug.cgi?id=35780 --- Comment #7 from Damjan Jovanovic <damjan.jov(a)gmail.com> --- Cura is open-source (AGPLv3), and the source code can be downloaded from: https://github.com/Ultimaker/Cura/archive/14.01.zip To build it, however, is a mission. Can you please test whether this is still an issue with Wine 5.0-rc2 or later? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
