I have installed Visual Studio 2010 and linked OpenCv 2.1
It works fine with image processing programs.But while i run a simple video capture program ,i get an error "msvcr90d.dll canot find".
Any clues on the problem?
I solved this problem by searching for msvcr90.dll on the C: drive and copied it over to the lib directory of OpenCV.
msvcr90d.dll is a dll in VS 2008, DO i need to install VS2008 ? And is it lib\debug to which i hav to copy the dll?
Hi,
Your error seems to be windows dll related but it can also come from some library install problems, is your dll corrupted ?
Also, when dealing with video processing, you need a video file decoder. FFMPEG is required.
Then, check your installation/configuration. If you recompile from sources, check if FFMPEG is found when configuring with the cmake tool.
Have a look at install guide for more details.
Hope it helps.
msvcr90.dll was the Visual C runtime library for Visual Studio 2008. You should be able to get the library only by downloading the redistributable for free from here http://www.microsoft.com/en-us/download/details.aspx?id=29.
I hav installed Microsoft Visual C++ 2008 Redistributable Setup, but i couldnt find msvcr90d.dll on C drive .Please help me ..
Whenever the redistributable is installed, the msvcr90.dll is in c:\winnt\system32 (perhaps winnt is name something else). Worst case, you could just copy the .dll into the folder where the executable is :)
Also you can take a look at this article from Ms where it tells you a bit the story. You are not the first one to stumble upon the .dll mess, that for sure ;)
