# - Try to find GStreamer and its plugins # Once done, this will define # # GSTREAMER_FOUND - system has GStreamer # GSTREAMER_INCLUDE_DIRS - the GStreamer include directories # GSTREAMER_LIBRARIES - link these to use GStreamer # # Additionally, gstreamer-base is always looked for and required, and # the following related variables are defined: # # GSTREAMER_BASE_INCLUDE_DIRS - gstreamer-base's include directory # GSTREAMER_BASE_LIBRARIES - link to these to use gstreamer-base # # Optionally, the COMPONENTS keyword can be passed to find_package() # and GStreamer plugins can be looked for. Currently, the following # plugins can be searched, and they define the following variables if # found: # # gstreamer-app: GSTREAMER_APP_INCLUDE_DIRS and GSTREAMER_APP_LIBRARIES # gstreamer-audio: GSTREAMER_AUDIO_INCLUDE_DIRS and GSTREAMER_AUDIO_LIBRARIES # gstreamer-fft: GSTREAMER_FFT_INCLUDE_DIRS and GSTREAMER_FFT_LIBRARIES # gstreamer-pbutils: GSTREAMER_PBUTILS_INCLUDE_DIRS and GSTREAMER_PBUTILS_LIBRARIES # gstreamer-video: GSTREAMER_VIDEO_INCLUDE_DIRS and GSTREAMER_VIDEO_LIBRARIES # # Copyright (C) 2012 Raphael Kubo da Costa # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.
