Trait containing all EncodingProfile methods.

Implementors

crate::EncodingAudioProfile, crate::EncodingContainerProfile, crate::EncodingProfile, crate::EncodingVideoProfile

Required methods

`fn copy(&self) -> EncodingProfile`[src]

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`[src]

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

`fn description(&self) -> Option<GString>`[src]

Returns

the description of the profile, can be None.

`fn file_extension(&self) -> Option<GString>`[src]

Returns

a suitable file extension for self, or NULL.

`fn format(&self) -> Caps`[src]

Returns

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

`fn input_caps(&self) -> Caps`[src]

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>`[src]

Returns

the name of the profile, can be None.

`fn presence(&self) -> u32`[src]

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>`[src]

Returns

the name of the crate::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>`[src]

Returns

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

`fn is_single_segment(&self) -> bool`[src]

This is supported on crate feature v1_18 only.

Returns

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