• Building OpenCV 2.4.11 on Linux with `libopencv_ffmpeg.so`

  28 décembre 2016, par SomethingSomething

  When downloading OpenCV sources, no matter whether it is for Windows or for Linux, the sources directory contains only the Windows already-compiled shared library 3rdparty/ffmpeg/opencv_ffmpeg.dll, that is essential for the VideoCapture module to work on the Python portings for OpenCV.

  In Linux, as this file is not provided, you’d expect it to be automatically built when you build OpenCV, especially when in CMakeCache.txt, you can spot the line WITH_FFMPEG:BOOL=ON.

  It is of course not built... Any idea ?

• use AForge.Video.FFMPEG.dll to grab video thumbnail

  5 avril 2015, par Sean

  I am using AForge.Video.FFMPEG.dll to grab video thumbnail on website, it will be shown on webpage or other clients. I downloaded latest version of the dll and related native library into /bin folder and copied to system32 folder as well.

  but when I compiled the project, it will told me :
  "
  Could not load file or assembly ’AForge.Video.FFMPEG.DLL’ or one of its dependencies. The specified module could not be found.
  "

  1. I copied all DLLs
     

  2. All DLLs are 32bit, not x64 bit.

  3. I saw another article to introduce how to load native c or managed c++ library in asp.net, but doesn’t work for me.
     http://blogs.msdn.com/b/jorman/archive/2007/08/31/loading-c-assemblies-in-asp-net.aspx

  4. My developing environment : Windows2012R2 VS2010

  5. When I was compiling the project, compiler will throw above exception.

  Thanks,

  Sean
