Hello everyone,
I am on Centos 6.5 64bit
ffmpeg is compiled successfully by following instructions here:
http://trac.ffmpeg.org/wiki/CompilationGuide/Centos
I get error when compiling opencv-2.4.11 with python2.7.6 and ffmpeg
version git-2015-03-21"
after make I get error. Did I compile the ffmpeg wrong or is the version of
ffmpeg too high for opencv?
