-# - Try to find ffmpeg libraries (libavcodec, libavformat and libavutil)

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

+# FFmpeg_INCLUDE_<component>: where to find <component>.h
+# FFmpeg_LIBRARY_<component>: where to find the <component> library
+# FFmpeg_INCLUDE_DIR: aggregate all the include paths

+# This module defines the following targets, which are prefered over variables:

+# FFmpeg::<component>: Target to use <component> directly, with include path,
+# library and dependencies set up. If you are using a static build, you are
