Which kind of element posted a crate::bus::BusEvent — cheap to compare/match, unlike the accompanying name: Arc<str> (an instance-level identifier chosen by whoever constructed it, needed alongside this to tell apart e.g. two Queues in the same pipeline; see Element::element_type).

Variants

FileDemuxer

File or container demultiplexer source.

AppSource

Application-fed buffer source.

RtspSource

RTSP network stream source.

TestVideoSource

Synthetic video source.

TestAudioSource

Synthetic audio source.

DxgiCaptureSource

Windows desktop-duplication capture source.

WgcCaptureSource

Windows Graphics Capture window source.

PipeWireAudioCaptureSource

PipeWire audio capture source.

PipeWireScreenCaptureSource

PipeWire screen capture source.

WasapiCaptureSource

Windows WASAPI audio capture source.

MfCaptureSource

Windows Media Foundation camera capture source.

V4l2CaptureSource

Linux V4L2 camera capture source.

AudioMixer

Multi-input audio mixer source.

AudioMixerInput

One input registered with an ElementType::AudioMixer, which is a Sink in whichever pipeline feeds it rather than part of the mixer’s own.

Its own variant because it reads as one: an input that called itself AudioMixer put a mixer at the end of every branch feeding one, and a topology diagram with four of them in it is a diagram nobody can count the mixers from.

Other

Anything outside this crate’s own elements — a test double, or a custom Sink/SourceElement implemented downstream of this crate. Keeps this enum from needing to grow every time someone adds their own element.
