DataSource
Object Hierarchy:
Description:
public interface DataSource : Object
Interface for all data streams provided by a #RygelMediaEngine.
The data source is responsible for providing the streamable byte-stream via its data_available signal. End-of-stream is signalled by the
done signal, while errors are signalled by the error signal.
Implementations should fulfil at least these requirements:
- It should support at least the file:// URI scheme.
- It should be able to stream any kind of binary data, regardless of the format.
Content:
Methods:
- public abstract void start (HTTPSeek? offsets) throws
Error
Start producing the data.
- public abstract void freeze ()
Temporarily stop data generation.
- public abstract void thaw ()
Resume data generation from a previous freeze call.
- public abstract void stop ()
Stop producing data. After calling stop(), calling start() should
produce data from the beginning and not resume streaming.
Signals:
- public signal void data_available (
uint8
[] data)
Emitted when the source has produced some data.
- public signal void done ()
Emitted when the source does not have data anymore.
- public signal void error (
Error
error)
Emitted when the source encounters a problem during data generation.
