c++ - How to solve OpenCV Error "function not implemented (called functionality is disabled for current build or platform) when using VideoWriter_GPU? -


question intro

i'm running opencv project in visual studios 2010 , have implemented cuda support (refer my previous question precise info on set-up). cuda-functionalities working fine - best of knowledge - , indeed improving speed on image processing.

however, wanted attemp speed video-writing function in project replacing current cv::videowriter gpu::videowriter_gpu function. reason cv::videowriter seems somehow cause processes running outside of scope in videowriter called slowed down, resulting in images available @ directshow driver being dropped videocapture-function, hence messing algorithm i've implemented.

problem

to attempt solve issue, i've replaced videowriter-calls videowriter_gpu-functionality (and corresponding syntax), when run project (compile & run in debug-mode), following error-message (directly originating atthe calling of gpu::videowriter_gpu):

opencv error: function/feature not implemented (the called functionality  disabled current build or platform) in unknown function, file  c:slave\builds\wininstallermegapack\opencv\modules\gpu\src\precomp.hpp, line 131.

and program ends with

   code -529697949 (0xe06d7363)

i've purposely not included of code because error-message originates call gpu::videowriter_gpu, making me think it's not coding or syntax problem. (please comment if feel code necessary answering question.

my steps far

i miss natural gift of understanding precisely message means or how interpret it. opencv v2.4.4 not support want...? function not work on windows 7, 64bit system...?

i've checked out many available google-hits find (relating error message , combinations of searchterms "opencv, gpu, videowriter_gpu, disabled current build") have not understood problem or how solve it.

corresponding header-file , error message can found here.

this post , this post suggest error message trying tell me opencv not provide option of using function or functionality aiming use. or maybe cuda not @ supported.. that's against experience every single opencv gpu-function i've tried use has seemed work fine.

question

could please explain me why not working me, , more importantly share me should make videowriter_gpu work?

many thanks!

maybe link can give little idea of problem is: videoreader_gpu not available, built nvcuvid?. seems problem cuda_disabler var.

c# - DetailsView in ASP.Net - How to add another column on the side/add a control in each row? -

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite
