I doubt you need to add any -extra-cflags. Once you install FFmpeg, run sudo ldconfig. Follow the how to compile FFmpeg () guide you linked to, except add -enable-shared during the x264 and FFmpeg. I'm not sure what OpenCV is or does, but I got it to compile:ġ. (This thread was posted in Multimedia forum but was suggested to move here) I would really appreciate if anyone could help! I'm stuck here, and I've been trying to get this working for the past 2 days.

This time, however, there is no configure script where I can set this option. However, I get the same compile error requesting I recompile with -fPIC when I try to make OpenCV. After building both x264 and ffmpeg with -enable-pic and -extra-cflags=-fPIC options, they both seem to work just fine.

After some more research, it seems to have to do with shared libraries and 64 bit architectures. When I do this, I get errors asking me to recompile with -fPIC set. The steps listed seem to work alright, though I apparently need to set -enable-shared as well. I am trying to follow the suggestion to recompile ffmpeg manually using this guide: After a fair amount of research, it seems this is caused by using a 'stripped' version of ffmpeg (LGPL instead of GPL). I'm trying to use OpenCV for video capture (and its other image processing features), but I get a steady stream of warnings from swscaler: 'no accelerated colorspace conversion found'.
