On Windows x64, I have a gstream pipeline program using OpenCV 2.4.8 throws run-time error about the procedure entry point findHomography not located in library avcodec-55.dll.

Here is the exact message on the dialog box:

"The procedure entry point ?findHomography@cv@@YA?AVMat@AEBV_InputArray@1@0HNAEBV_OutputArray@1@@Z could not be located in the dynamic link library avcode-55.dll."

I have no clue how to debug this issue or what to try. I appreciate your pointers if you come across similar issue or suggest me how to debug such issue.

Regards, Amit!

  • This looks like it is not able to link the library. Have you checked your linker/include settings for openCV are correct? – GPPK Jun 09 '14 at 14:47
  • This run-time error goes away if I use debug OpenCV dlls. Still no idea why release OpenCV dlls give run-time error. Hoping someone will know about it. Thanks! – arm Jun 09 '14 at 22:56

  1. You have not downloaded or built the OpenCV Libraries in release mode (the would be named something like opencv_Core248.dll) & you will need to do so and link them in.

  2. You have linked inside visual studio the opencv_core249 d.dll libraries and not linked in the release libraries which do not have the d
