# Find ffmpeg/libav libraries (libavcodec, libavformat and libavutil)
# Once done this will define
#
#  FFMPEG_FOUND             - system has libavcodec, libavformat, libavutil
#  FFMPEG_INCLUDE_DIR       - the libav include directories
#  FFMPEG_LIBRARIES         - the libav libraries
#
#  LIBAVCODEC_LIBRARY      - the libavcodec library
#  LIBAVCODEC_INCLUDE_DIR  - the libavcodec include directory
#  LIBAVFORMAT_LIBRARY     - the libavformat library
#  LIBAVUTIL_LIBRARY       - the libavutil library
