Membrane.Source (Membrane Core v0.7.0) View Source
Module that should be used in sources - elements producing data. Declares appropriate behaviours implementation and provides default callbacks implementation.
Source elements can define only output pads. Job of a usual source is to produce
some data (read from soundcard, download through HTTP, etc.) and send it through
such pad. If the pad works in pull mode, then element is also responsible for
receiving demands and send buffers only if they have previously been demanded
(for more details, see
Sources, like all elements, can of course have multiple pads if needed to
provide more complex solutions.
