问题 I'm having trouble with Camera.getCamera() in Flash AS3. If there are multiple camera drivers, it does not necessarily pick the correct one. If the default is the correct, the program works fine; however, if another driver is selected as the default then LED on the webcam does not come on and no video is captured. I can cycle through the available cams and select an arbitrary one. I don't, however, know how to determine if the selected camera is correct. It is not returning null. I considered

问题 I would like someone's advice to find a solution for this situation. Basically what I need is to have a permanent web conference room in my web application to handle remote interviews.

I did a little research about this topic and I have found several different solutions but none of them, at least at first

问题 I'm using DirectShowNet in C#. I've been developing an application to work with webcams to display video, change resolution, and take pictures (either Still pin or from the Capture stream). I've been testing it on 2 different machines (Win 7 64-bit & Win 8 64-bit) and with the internal webcams on those machines (they are laptops) and 2 other webcams, Logitech C920 and Microsoft LifeCam Studio. One day, the LifeCam Studio stopped working on my Win 8 machine. Using GraphEditPlus, checking the

问题 A while ago I had this issue with Delphi 2007 unable to run and debug apps while the logitech webcam driver runs. Apparently the Logitech Driver inserts a stub into every process running, thereby messing up the debugger's offset. It's been a year and a bit - is this still an issue? Has Logitech cleaned up their act or do I have to dump my webcam for another brand? 回答1: According to Olaf Monien the problem still happening even in Delphi 2009 Apparently even with the latest Logitech drivers (11

问题 I have written a program using Python and OpenCV where I perform operations on a video stream in run time. It works fine. Now if I want to publish it on a website where someone can see this using their browser and webcam, how do I proceed? 回答1: not really sure what you want to happen but if your going to implement this kind of feature in a website I think you should use a flash application instead of python (or if possible html 5). though your using python on the development of you web app it

问题 I'm making simple webcam program using OpenCV 2.3 and got stuck by the compile error. Any idea will be appreciated. Upon compile, I get the following error at imwrite (in read function in the code below). This sample that uses imwrite to save an image works on my environment, which indicates imwrite in OpenCV 2.3 should work on my env. error: error: invalid initialization of reference of type ‘const cv::_InputArray&’ from expression of type ‘cv::Mat*’ /usr/local/include/opencv2/highgui

问题 I want to develop an App that requires wired communication between Web cam type video camera and iPad2. Basically I will directly connect Web cam and iPad2 using cable and when I start web cam, whatever images(picture/video) captured by web cam should be displayed on iPad2. Based on my research on this I found that iPad2 cable is only made for iPod Program so the connector is not a traditional USB port I can't do direct communication between web cam and iPad2. Am I missing anything? We are
