## Member Function Documentation

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_audio_streams | ( |  | ) |

Finds all the Gst::DiscovererAudioInfo contained in info.

Returns:
  A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_audio_streams | ( |  | ) | const

Finds all the Gst::DiscovererAudioInfo contained in info.

Returns:
  A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_container_streams | ( |  | ) |

Finds all the Gst::DiscovererContainerInfo contained in info.

Returns:
  A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_container_streams | ( |  | ) | const

Finds all the Gst::DiscovererContainerInfo contained in info.

Returns:
  A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

ClockTime Gst::DiscovererInfo::get_duration | ( |  | ) | const

Returns:
  The duration of the URI in Gst::ClockTime (nanoseconds).

Structure Gst::DiscovererInfo::get_misc | ( |  | ) | const

Returns:
  Miscellaneous information stored as a Gst::Structure (for example: information about missing plugins). If you wish to use the Gst::Structure after the life-time of info, you will need to copy it.

DiscovererResult Gst::DiscovererInfo::get_result | ( |  | ) | const

Returns:
  The result of the discovery as a Gst::DiscovererResult.

bool Gst::DiscovererInfo::get_seekable | ( |  | ) | const

Returns:
  The wheter the URI is seekable.

Glib::RefPtr<const DiscovererStreamInfo> Gst::DiscovererInfo::get_stream_info | ( |  | ) | const

Returns:
  The structure (or topology) of the URI as a Gst::DiscovererStreamInfo. This structure can be traversed to see the original hierarchy. Unref with gst_discoverer_stream_info_unref() after usage.

Glib::RefPtr<DiscovererStreamInfo> Gst::DiscovererInfo::get_stream_info | ( |  | ) |

Returns:
  The structure (or topology) of the URI as a Gst::DiscovererStreamInfo. This structure can be traversed to see the original hierarchy. Unref with gst_discoverer_stream_info_unref() after usage.

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_stream_list | ( |  | ) |

Returns:
  The list of all streams contained in the #info. Free after usage with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_stream_list | ( |  | ) | const

Returns:
  The list of all streams contained in the #info. Free after usage with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_streams | ( | GType | streamtype | ) | const

Finds the Gst::DiscovererStreamInfo contained in info that match the given streamtype.

Parameters:

  streamtype | A Type derived from Gst::DiscovererStreamInfo.

Returns:
  A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_streams | ( | GType | streamtype | ) |

Finds the Gst::DiscovererStreamInfo contained in info that match the given streamtype.

Parameters:

  streamtype | A Type derived from Gst::DiscovererStreamInfo.

Returns:
  A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

TagList Gst::DiscovererInfo::get_tags | ( |  | ) | const

Returns:
  All tags contained in the U::RI. If you wish to use the tags after the life-time of info, you will need to copy them.

Returns:
  The URI to which this information corresponds to. Copy it if you wish to use it after the life-time of info.

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_video_streams | ( |  | ) | const

Finds all the Gst::DiscovererVideoInfo contained in info.
