2014-10-30 15:18:42 -0600 | commented question | OpenCV Cross Compile Issue for ARM with FFMPEG support on x86 host I used this to print out where the libs are message(STATUS "CMAKE_LIBRARY_PATH is " ${CMAKE_LIBRARY_PATH}) message(STATUS "CMAKE_INCLUDE_PATH is " ${CMAKE_INCLUDE_PATH}) message(STATUS "PKG_CONFIG_PATH is " $ENV{PKG_CONFIG_PATH}) It does point to the ffmpeg cross compiled lib path. |

2014-10-28 18:37:22 -0600 | asked a question | OpenCV Cross Compile Issue for ARM with FFMPEG support on x86 host I am trying to compile OpenCV with ffmpeg support for ARM Platform on a x86 host. I downloaded and compiled ffmpeg for arm platform (both static - FFMPEG_ARM_LIB and dynamic libs - FFMPEG_ARM_LIB_SO) When I run cmake in opencv, it gives the following - -- Video I/O:
I changed the following flags to point to the lib paths of both ffmpeg static and dynamic libs- However, the opencv is still not able to recognize the ffmpeg libs. My FFMPEG compilation command was ./configure --enable-shared --disable-static\ --cross-prefix=arm-linux-gnueabi- --arch=armv7a\ --target-os=linux --prefix=<path> What am I doing wrong here? 1. Am I compiling the ffmpeg with the wrong option? 2. Am I missing some element in CMake which would make it point to the compiled ffmpeg lib for ARM on my system?
