  FFmpeg examples README
  ----------------------
  
  Both following use cases rely on pkg-config and make, thus make sure
  that you have them installed and working on your system.
  
  
  Method 1: build the installed examples in a generic read/write user directory
  
  Copy to a read/write user directory and just use "make", it will link
  to the libraries on your system, assuming the PKG_CONFIG_PATH is
  correctly configured.
  
  Method 2: build the examples in-tree
  
  Assuming you are in the source FFmpeg checkout directory, you need to build
  FFmpeg (no need to make install in any prefix). Then just run "make examples".
  This will build the examples using the FFmpeg build system. You can clean those
  examples using "make examplesclean"
  
  If you want to try the dedicated Makefile examples (to emulate the first
  method), go into doc/examples and run a command such as
  PKG_CONFIG_PATH=pc-uninstalled make.
