DataSource
Object Hierarchy:
Description:
public interface DataSource : Object
Interface for all data streams from a media engine. The data source is responsible for providing the streamable byte-stream via its
data_available signal. End-of-stream is signalled through the done signal, while errors are signalled by using the error signal.
# The only required URI scheme is file:/""/ # A DataSource should be able to stream any kind of binary data, regardless of the format

- public abstract void start (HTTPSeek? offsets) throws
