I solved this problem by searching for msvcr90.dll on the C: drive and copied it over to the lib directory of OpenCV.

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.

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 ;)
