I would like to use the ffmpeg library so I have video support with my OpenCV 3.0 build. I'm using the excellent step-by-step instructions from the book Practical OpenCV by Samarth Brahmbhatt (http://www.it-ebooks.info/book/3145/) But every time I run `make`, the build quits while trying to link libopencv_videoio.so, and throws this error:> Linking CXX shared library> ../../lib/libopencv_videoio.so>> /usr/bin/ld:> /usr/local/lib/libavcodec.a(vc1dsp_mmx.o):> relocation R_X86_64_PC32 against> symbol `ff_pw_9' can not be used when> making a shared object; recompile with> -fPIC
First, there was actually some similar error, and I fixed it by recompiling x264 with the additional option `--enable-pic`. That was easy.
But I've recompiled ffmpeg a bunch of times, with the options `--extra-cflags=-fPIC`, `--extra-cxxflags=-fPIC`, `--enable-pic`, and nearly every combination of those options. Nothing will make this work.
I don't have any problem following the same steps with OpenCV 2.4.9.
Help!
