If you're interested in higher reputation, you can consider answering this same question on StackOverflow; else I will link to your answer from there. |

One might acchieve an equivalent solution to your problem, but then for v2.4.4 and Visual Studios 2010, by following my steps indicated in this answer to my own question, posted a little while ago. |

I've asked this question on StackOverflow, but only received comment to 'refer to OpenCV developers'. Hence this post, which one could view as being a repost. My apologies for my internet-littering, however I do still believe this is a relevant question for this forum and it's members. |
2013-05-16 06:51:40 -0600 | asked a question | How to solve OpenCV Error "function not implemented (called functionality is disabled for current build or platform) when using VideoWriter_GPU? My Hard- & Software:
Question Intro I'm running an opencv project in Visual Studios 2010 and have implemented cuda support. All cuda-functionalities are working fine - to the best of my knowledge - and are indeed improving speed on the image processing, no errors encountered. However, I now also wanted to attemp to speed up the video-writing function in this project of mine by replacing the current cv::VideoWriter with the gpu::VideoWriter_GPU function. (The reason for this is that the cv::VideoWriter seems to somehow cause processes running outside of the scope in which the VideoWriter is called to be slowed down, resulting in images available at the DirectShow driver being dropped by the VideoCapture-function, hence messing up an algorithm I've implemented. But that issue's worth a seperate question) Problem To attempt to speed-up the , I've now replaced the VideoWriter-calls with calls to the VideoWriter_GPU-functionality (and correspondingly adapted syntax, and naturally provided the function with GpuMat's). When I run my project (Compile & Run in Debug-mode), I get the following error-message (directly originating at the calling of gpu::VideoWriter_GPU):
and the program then ends with
Corresponding header-file and error message can also be viewed here. The thrown error also refers back to a CV_ERROR-code (to be found in header file ...\build\include\opencv2\core\types_c.h) which reads:
I've purposely currently not included any of my actual code, because the error-message originates so clearly from the call to the gpu::VideoWriter_GPU, which is making me think it's not a coding or syntax problem. (Please leave a comment if you feel my code is necessary for answering this question. My steps so far I miss the natural gift of understanding what precisely this message means or how to interpret it, or how to search deeper into openCV sourcecode to find the origin of the error. Does my opencv v2.4.4 simply not support what I want...? Does this function simply not work on my windows 7, 64bit system...? Or maybe is Sourceforge's precompiled OpenCV v2.4.4 limited? OpenCV documentation neither on v2.4.4 nor v2.4.5 provide with any clarity regarding versioned use or build-availability of the function Further, I've checked out as many available google-hits ...

2013-05-02 08:44:30 -0600 | asked a question | OpenCV 2.4.5.0 Documentation gpu::subtract says "const GpuMat& b to be ADDED to const GpuMat& a" In the OpenCV 2.4.5.0 Documentation on docs.opencv.org, I was looking up the parameters to be passed to the function gpu::subtract(). Unexpectedly, it states for parameter GpuMat& b Does this really mean that the second GpuMat will be ADDED to the first (even though this is supposed to be the gpu:subtract()-function). Or is this a type-error? (the parameter-declaration written with the function gpu:add() has the exact same words as the gpu::subtract()-function, suggesting to me that this may indeed be a typo... I still would like to know for sure though, and otherwise bring this to the attention. |
