Overview

A stage is a discrete processing unit with defined inputs and outputs. Stages are connected together to form a directed processing graph, where data flows along connections between stage outputs and stage inputs. There are 4 stage types in decode-orc:

• Source stages are the starting point of every decode-orc pipeline. They load captured video (and any associated audio or data) from disk and make it available for further processing.
• Transform stages are where most of the real work in decode-orc happens. They take video from a source stage (or another transform stage) and modify, combine, or reinterpret it to improve quality or prepare it for output.
• Media sink stages terminate a pipeline by writing decoded or processed media/data to disk or external hardware.
• Analysis sink stages compute diagnostics and measurements and write analysis results to disk. They do not produce media streams.

Since there are quite a large number of sink stages they are divided into 3 sub-sections:

• Sink (Core) - These are the core ld-decode and vhs-decode supporting sinks
• Sink (Analysis) - There are analysis sinks that output statistics
• Sink (3rd Party) - These are sinks to support 3rd party application such as HackDAC and Daphne
