Interface:
|
||
|
|
- type (string like caps) channels/x-mpegts-pat
|
||
|
|
- GstStructure to describe the what the list is, name, where from etc. (how many entries you can select, if multiple tried, first one picked)
|
||
|
|
- method to list entries (channels)
|
||
|
|
- method to get current entries
|
||
|
|
- method to set list of entries
|
||
|
|
- each entry contains an id (32 bit int say), GstStructure (with additional stuff)
|
||
|
|
|
||
|
|
signals to say when entry list changes
|
||
|
|
to say when current entry changes
|
||
|
|
|
||
|
|
So for a transport stream, this interface would be exported and it could contain a list of interfaces...eg it would export PAT, and PAT list would contain interfaces in the GstStructure for the PMT.
|
||
|
|
|
||
|
|
dvbsrc -> list of frequencies
|
||
|
|
flutsdemux -> list of programs (PAT) and list of PMT streams per program
|
||
|
|
|
||
|
|
get list of frequencies, select frequency
|
||
|
|
get list of programs, select programs
|
||
|
|
get list of streams, select streams
|
||
|
|
|
||
|
|
only give program details in PAT list, when we have seen the PMT for that program.
|
||
|
|
|
||
|
|
possibly another interface to select multiple list interfaces from an element. (interface selector interface)

other option is to tag
