Trait containing all RTSPOnvifMediaFactory methods.

§Implementors

RTSPOnvifMediaFactory

Provided Methods§

Source

fn backchannel_bandwidth(&self) -> u32

Get the configured/supported bandwidth of the ONVIF backchannel pipeline in bits per second.

§Returns

the configured/supported backchannel bandwidth.

Source

fn backchannel_launch(&self) -> Option<GString>

Get the gst_parse_launch() pipeline description that will be used in the default prepare vmethod for generating the ONVIF backchannel pipeline.

§Returns

the configured backchannel launch description. g_free() after usage.

Source

fn has_backchannel_support(&self) -> bool

Returns true if an ONVIF backchannel is supported by the media factory.

§Returns

true if an ONVIF backchannel is supported by the media factory.

Source

fn has_replay_support(&self) -> bool

§Returns

true if ONVIF replay is supported by the media factory.

Source

fn set_backchannel_bandwidth(&self, bandwidth: u32)

Set the configured/supported bandwidth of the ONVIF backchannel pipeline in bits per second.

§bandwidth

the bandwidth in bits per second

Source

fn set_backchannel_launch(&self, launch: Option<&str>)

The gst_parse_launch() line to use for constructing the ONVIF backchannel pipeline in the default prepare vmethod if requested by the client.

The pipeline description should return a GstBin as the toplevel element which can be accomplished by enclosing the description with brackets ‘(’ ‘)’.

The description should return a pipeline with a single depayloader named depay_backchannel. A caps query on the depayloader’s sinkpad should return all possible, complete RTP caps that are going to be supported. At least the payload type, clock-rate and encoding-name need to be specified.

Note: The pipeline part passed here must end in sinks that are not waiting until pre-rolling before reaching the PAUSED state, i.e. setting async=false on GstBaseSink. Otherwise the whole media will not be able to prepare.

§launch

the launch description

Source

fn set_replay_support(&self, has_replay_support: bool)

Set to true if ONVIF replay is supported by the media factory.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
