2015-03-23 18:29:54 -0600 | asked a question | Build libopencv_ffmpeg.so on Linux/OSX Hi, I built opencv(3.0 Beta) on windows which supports ffmpeg as a loadable library called opencv_ffmpeg.dll, I find it is quite convenient to use ffmpeg that way. Is that possible to build ffmpeg to libopencv_ffmpeg.so on Linux and MacOS and load it dynamically? Thanks. Best Regards, Pelscope |
