Implementations
impl DiscovererInfo[src]
impl DiscovererInfo[src]pub fn copy(&self) -> DiscovererInfo[src]
pub fn copy(&self) -> DiscovererInfo[src]Returns
A copy of the crate::DiscovererInfo
pub fn audio_streams(&self) -> Vec<DiscovererStreamInfo>[src]
pub fn audio_streams(&self) -> Vec<DiscovererStreamInfo>[src]Finds all the crate::DiscovererAudioInfo contained in self
Returns
A [crate::glib::List] of
matching crate::DiscovererStreamInfo. The caller should free it with
[crate::DiscovererStreamInfo::list_free()].
pub fn container_streams(&self) -> Vec<DiscovererStreamInfo>[src]
pub fn container_streams(&self) -> Vec<DiscovererStreamInfo>[src]Finds all the crate::DiscovererContainerInfo contained in self
Returns
A [crate::glib::List] of
matching crate::DiscovererStreamInfo. The caller should free it with
[crate::DiscovererStreamInfo::list_free()].
pub fn duration(&self) -> ClockTime[src]
pub fn duration(&self) -> ClockTime[src]Returns
the duration of the URI in crate::gst::ClockTime (nanoseconds).
pub fn is_live(&self) -> bool[src]

This functions is deprecated since version 1.4, use
[Self::get_missing_elements_installer_details]
Returns
Miscellaneous information stored as a crate::gst::Structure
(for example: information about missing plugins). If you wish to use the
crate::gst::Structure after the life-time of self, you will need to copy it.
pub fn missing_elements_installer_details(&self) -> Vec<GString>[src]
pub fn missing_elements_installer_details(&self) -> Vec<GString>[src]Get the installer details for missing elements
Returns
An array of strings
containing information about how to install the various missing elements
for self to be usable. If you wish to use the strings after the life-time
of self, you will need to copy them.

gst_discoverer_stream_info_unref() after usage.
pub fn stream_list(&self) -> Vec<DiscovererStreamInfo>[src]
pub fn stream_list(&self) -> Vec<DiscovererStreamInfo>[src]Returns
the list of
all streams contained in the info. Free after usage
with [crate::DiscovererStreamInfo::list_free()].

given streamtype.
streamtype
a crate::glib::Type derived from crate::DiscovererStreamInfo

pub fn subtitle_streams(&self) -> Vec<DiscovererStreamInfo>[src]Finds all the crate::DiscovererSubtitleInfo contained in self
Returns
A [crate::glib::List] of
matching crate::DiscovererStreamInfo. The caller should free it with
[crate::DiscovererStreamInfo::list_free()].
pub fn tags(&self) -> Option<TagList>[src]
pub fn tags(&self) -> Option<TagList>[src]Returns
all tags contained in the URI. If you wish to use
the tags after the life-time of self, you will need to copy them.
pub fn toc(&self) -> Option<Toc>[src]
pub fn toc(&self) -> Option<Toc>[src]Returns
TOC contained in the URI. If you wish to use
the TOC after the life-time of self, you will need to copy it.
pub fn uri(&self) -> Option<GString>[src]
pub fn uri(&self) -> Option<GString>[src]Returns
the URI to which this information corresponds to.
Copy it if you wish to use it after the life-time of self.

pub fn video_streams(&self) -> Vec<DiscovererStreamInfo>[src]Finds all the crate::DiscovererVideoInfo contained in self
Returns
A [crate::glib::List] of
matching crate::DiscovererStreamInfo. The caller should free it with
[crate::DiscovererStreamInfo::list_free()].
pub fn to_variant(
&self,
flags: DiscovererSerializeFlags
) -> Result<Variant, BoolError>[src]
pub fn to_variant(
&self,
flags: DiscovererSerializeFlags
) -> Result<Variant, BoolError>[src]Serializes self to a crate::glib::Variant that can be parsed again
through Self::from_variant().
Note that any crate::gst::Toc (s) that might have been discovered will not be serialized
for now.
flags
A combination of crate::DiscovererSerializeFlags to specify
what needs to be serialized.
Returns
A newly-allocated crate::glib::Variant representing self.
pub fn from_variant(variant: &Variant) -> Result<DiscovererInfo, BoolError>[src]
