Implementors
crate::DiscovererAudioInfo, crate::DiscovererContainerInfo, crate::DiscovererStreamInfo, crate::DiscovererSubtitleInfo, crate::DiscovererVideoInfo
Required methods
fn caps(&self) -> Option<Caps>[src]
Returns
the crate::gst::Caps of the stream. Unref with
gst_caps_unref after usage.
fn misc(&self) -> Option<Structure>[src]
Deprecated
This functions is deprecated since version 1.4, use
[crate::DiscovererInfo::get_missing_elements_installer_details]
Returns
additional information regarding the stream (for
example codec version, profile, etc..). If you wish to use the crate::gst::Structure
after the life-time of self you will need to copy it.
fn next(&self) -> Option<DiscovererStreamInfo>[src]
Returns
the next crate::DiscovererStreamInfo in a chain. None
for final streams.
Unref with gst_discoverer_stream_info_unref after usage.
fn previous(&self) -> Option<DiscovererStreamInfo>[src]
Returns
the previous crate::DiscovererStreamInfo in a chain.
None for starting points. Unref with gst_discoverer_stream_info_unref
after usage.
fn stream_id(&self) -> Option<GString>[src]
Returns
the stream ID of this stream. If you wish to
use the stream ID after the life-time of self you will need to copy it.
fn stream_type_nick(&self) -> GString[src]
Returns
a human readable name for the stream type of the given self (ex : “audio”,
“container”,…).
fn tags(&self) -> Option<TagList>[src]
Returns
the tags contained in this stream. If you wish to
use the tags after the life-time of self you will need to copy them.
fn toc(&self) -> Option<Toc>[src]
Returns
the TOC contained in this stream. If you wish to
use the TOC after the life-time of self you will need to copy it.
