General-purpose signalization demux.
|
explicit |
Constructor for full services and PID's analysis.
All signalization is demuxed. A full map of services and PID's is internally built. This is the typical constructor to use the application only needs to query the structure of services and PID's. It is still possible to add a handler for signalization tables later.
When the demux is reset, the full filtered are restored.
[in,out] | duck | TSDuck execution context. The reference is kept inside the demux. Contextual information (such as standards) are accumulated in the context from demuxed sections. |
