| # - 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-gl: GSTREAMER_GL_INCLUDE_DIRS and GSTREAMER_GL_LIBRARIES |
| # gstreamer-mpegts: GSTREAMER_MPEGTS_INCLUDE_DIRS and GSTREAMER_MPEGTS_LIBRARIES |
| # gstreamer-pbutils: GSTREAMER_PBUTILS_INCLUDE_DIRS and GSTREAMER_PBUTILS_LIBRARIES |
| # gstreamer-tag: GSTREAMER_TAG_INCLUDE_DIRS and GSTREAMER_TAG_LIBRARIES |
| # gstreamer-video: GSTREAMER_VIDEO_INCLUDE_DIRS and GSTREAMER_VIDEO_LIBRARIES |
| # gstreamer-codecparser:GSTREAMER_CODECPARSERS_INCLUDE_DIRS and GSTREAMER_CODECPARSERS_LIBRARIES |
