Trait containing all EncodingProfile methods.

Implementors

EncodingAudioProfile, EncodingContainerProfile, EncodingProfile, EncodingVideoProfile

Required methods

fn copy(&self) -> EncodingProfile

This is supported on crate feature v1_12 only.

Makes a deep copy of self

Returns

The copy of self

fn allows_dynamic_output(&self) -> bool

Get whether the format that has been negotiated in at some point can be renegotiated later during the encoding.

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

Returns

the description of the profile, can be None.

fn element_properties(&self) -> Option<Structure>

This is supported on crate feature v1_20 only.

Returns

The properties that are going to be set on the underlying element

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

Returns

a suitable file extension for self, or NULL.

fn format(&self) -> Caps

Returns

the gst::Caps corresponding to the media format used in the profile. Unref after usage.

fn input_caps(&self) -> Caps

Computes the full output caps that this self will be able to consume.

Returns

The full caps the given self can consume. Call gst_caps_unref() when you are done with the caps.

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

Returns

the name of the profile, can be None.

fn presence(&self) -> u32

Returns

The number of times the profile is used in its parent container profile. If 0, it is not a mandatory stream.

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

Returns

the name of the gst::Preset to be used in the profile. This is the name that has been set when saving the preset.

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

Returns

the name of the gst::Preset factory to be used in the profile.

fn is_single_segment(&self) -> bool

This is supported on crate feature v1_18 only.

Returns

true if the stream represented by self should use a single segment before the encoder, false otherwise. This means that buffers will be retimestamped and segments will be eat so as to appear as one segment.

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

Returns

the human-readable name of the type of self.

fn is_enabled(&self) -> bool

fn is_equal<P: IsA<EncodingProfile>>(&self, b: &P) -> bool

Checks whether the two EncodingProfile are equal

b

a EncodingProfile

Returns

true if self and b are equal, else false.

fn connect_element_properties_notify<F: Fn(&Self) + Send + Sync + 'static>(
    &self,
    f: F
) -> SignalHandlerId

This is supported on crate feature v1_20 only.
