# - 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-interfaces: GSTREAMER_INTERFACES_INCLUDE_DIRS and GSTREAMER_INTERFACES_LIBRARIES
|
||
|
# gstreamer-pbutils: GSTREAMER_PBUTILS_INCLUDE_DIRS and GSTREAMER_PBUTILS_LIBRARIES
|

# gstreamer-video: GSTREAMER_VIDEO_INCLUDE_DIRS and GSTREAMER_VIDEO_LIBRARIES
