cutcutcodec.core.classes.stream

Defines the structure of an abstract multimedia stream.

Classes

`Stream`(node)	A General multimedia stream.
`StreamWrapper`(node, index)	Allow to dynamically transfer the methods of an instanced stream.

Details

class cutcutcodec.core.classes.stream.Stream(node)[source]

A General multimedia stream.

Attributes

beginningFraction: The stream beginning instant in second (readonly).
durationFraction or inf: The duration of the flow in seconds, it can be infinite (readonly). This value needs to be accurate.
indexint: The absolute stream index from the parent node (0 to n-1) (readonly).
nodecutcutcodec.core.classes.node.Node: The node where this stream comes from (readonly). Allows back propagation in the assembly graph.
node_maincutcutcodec.core.classes.node.Node: The node used for the compilation. This node has the same output_streams as node but not nescessary the same input_streams and te same properties. It can be used for factorisation (read and write).

Initialise and create the class.

nodecutcutcodec.core.classes.node.Node: The node where this stream comes from. The audit must be conducted in the children’s classes. It is not done here in order to avoid cyclic imports.
node_maincutcutcodec.core.classes.node.Node: In the case this streams comes from cutcutcodec.core.filter.meta_filter.MetaFilter, node_main is the meta filter while node is the subgraph of the meta-filter.

class cutcutcodec.core.classes.stream.StreamWrapper(node, index: Integral)[source]

Allow to dynamically transfer the methods of an instanced stream.

streamcutcutcodec.core.classes.stream.Stream: The stream containing the properties to be transferred (readonly). This stream is one of the input streams of the parent node.

Initialise and create the class.

nodecutcutcodec.core.classes.node.Node: The parent node, transmitted to cutcutcodec.core.classes.stream.Stream.
indexnumber.Integral: The index of the stream among all the input streams of the node. 0 for the first, 1 for the second …
