[MPlayer-G2-dev] Communication between layers?

[Nico]

Hi,

it seems my message wan never delivered nor archived, so here it is again.

The question is: is there an api to permit 2-way communication between 
layers (stream and demuxer in my case)?

An application (that I care for) is:

1) the dvb input module opens the device and sets filters for pids 160 
(V), 80 (A), eventually 500 (subs) and 0
    (for PAT, that I'm working on)
2) the ts_demuxer queues the usual a/v/s content to the respective fifos 
and parses the PAT to find the PMT(same as above) pids
3) at this point ts_demux needs more TS pids: the ones corresponding to 
the PMTs found in the PAT, so it needs to ask the
    dvb stream module to add more  pids to the stream. How to do it?
4) the dvb module tries to obey and needs to report the exit code to the 
demuxer
5) ts_demux needs to parse the PMTs and can decide to add or remove 
certain pids from the stream;
    it can also tell the dvb module that there are more channels 
available in the same frequency
    or what's the map of the other frequencies found in the NIT (i'm 
overly optimistic in this case).


Thanks,

        Nico
