Contents
Description
AudioFilter is a BaseTransform-derived base class for simple audio
filters, ie. those that output the same format that they get as input.
AudioFilter will parse the input format for you (with error checking)
before calling your setup function. Also, elements deriving from
AudioFilter may use audioFilterClassAddPadTemplates from
their class_init function to easily configure the set of caps/formats that
the element is able to handle.
Derived classes should override the AudioFilterClass.setup() and
BaseTransformClass.transform_ip() and/or
BaseTransformClass.transform()
virtual functions in their class_init function.
Synopsis
- newtype AudioFilter = AudioFilter (ManagedPtr AudioFilter)
- class (GObject o, IsDescendantOf AudioFilter o) => IsAudioFilter o
- toAudioFilter :: (MonadIO m, IsAudioFilter o) => o -> m AudioFilter
