# - Try to find Gstreamer and its plugins
|

|
|
|
# Once done, this will define
|

#
|
|
|
|
|
# GSTREAMER_1_0_FOUND - system has Gstreamer
|
|
|
|
|
# GSTREAMER_1_0_INCLUDE_DIRS - the Gstreamer include directories

|
# GSTREAMER_1_0_LIBRARIES - link these to use Gstreamer
|
|
|
|
|
#
|

# Additionally, gstreamer-base is always looked for and required, and
|
|
|

# the following related variables are defined:
|
|
|
|
|
#
|
|
|
|

# GSTREAMER_1_0_BASE_INCLUDE_DIRS - gstreamer-base's include directory

|
|
# 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_1_0_APP_INCLUDE_DIRS and GSTREAMER_1_0_APP_LIBRARIES
