| 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 |
