# - Try to find ffmpeg libraries (libavcodec, libavformat and libavutil)
# Once done this will define

# FFMPEG_FOUND - system has ffmpeg or libav
# FFMPEG_INCLUDE_DIR - the ffmpeg include directory
# FFMPEG_LIBRARIES - Link these to use ffmpeg
# FFMPEG_LIBAVCODEC
# FFMPEG_LIBAVFORMAT
# FFMPEG_LIBAVUTIL
