Scope of Issue:

When ffmpeg is built for static library and this compiled static library is linked with another dynamic library then the final linking failed with error --

ffmpeg/libavcodec/libavcodec.a(xx_yyyy.o): relocation R_X86_64_PC32 against symbol `ff_xx_yy_zz_qq' can not be used when making a shared object; recompile with -fPIC

How to fix:

Use the ffmpeg-2.2.patch in your FFmpeg-n2.2 release source.

How to apply patch:

  1. Copy the downloaded patch to your FFmpeg-n2.2 folder.
  2. Test the patch compatibility with your ffmpeg source by --
patch --dry-run -p1 -i  ffmpeg-2.2.patch
giving this command inside your ffmpeg source folder.
  1. If the test returns no fail patch file then you are good to patch.
  2. Now patch by following command --
patch -p1 -i ffmpeg-2.2.patch
  1. Now enjoy linking with your any other project library !!
Note: I am not in blame for any other issue and any other copyright law , if ffmpeg have any for this. This is only a remedy for the group who suffers from this compilation errors.
