August'24: Kamaelia is in maintenance mode and will recieve periodic updates, about twice a year, primarily targeted around Python 3 and ecosystem compatibility. PRs are always welcome. Latest Release: 1.14.32 (2024/3/24)

Kamaelia.Codec.Vorbis.AOAudioPlaybackAdaptor

For examples and more explanations, see the module level docs.

class AOAudioPlaybackAdaptor(Axon.Component.component)

AOAudioPlaybackAdaptor() -> new AOAudioPlaybackAdaptor

Expects to recieve data from standard inbox, and plays it using libao. When it recieves a message on the control port: Sends a producerConsumed to its outbox. Then shutsdown.

Requires libao and pyao (python bindings)

Example

A simple player:

Pipeline(
    ReadFileAdaptor("somefile.ogg"),
    VorbisDecode(),
    AOAudioPlaybackAdaptor(),
).run()

Inboxes

control : If a message is received here, the component shutsdown
inbox : Any raw PCM encoded data recieved here is played through the default oss playback device

Outboxes

outbox : UNUSED
signal : When the component shutsdown, it sends a producerFinished message out this outbox

Methods defined here

Warning!

You should be using the inbox/outbox interface, not these methods (except construction). This documentation is designed as a roadmap as to their functionalilty for maintainers and new component developers.

init(self)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

main(self)

Performs the logic described above
