If I understand what you mean:
1) I add an array mpMediaEventListeners of IMediaEventListener* to
MpCallFlowGraph.
In MpCallFlowGraph constructor, I initialize the array elements to NULL as
all flowgraph arrays.
2) In MpCallFlowGraph::createConnection( IMediaEventListener*
pMediaEventListener=NULL ), I store pMediaEventListener to the "found
ConnectionId" array slot.
3) In a resource linked to a specific connection such as mpDecodeInBandDtmf,
I send notifications like this:
if( ((MpCallFlowGraph*)mpFlowGraph)->mpMediaEventListeners[mConnectionId] !=
null )
{
((MpCallFlowGraph*)mpFlowGraph)->mpMediaEventListeners[mConnectionId]->onInB
andDtmf(IDevice_Audio, dtmfDigit );
}
The cast from MpFlowGraphBase to MpCallFlowGraph isn't very clean. What
about the "new" resource notification scheme you are all talking about ? I
would also like to use this to get MEDIA_PLAYBUFFER_START/STOP and
MEDIA_PLAYFILE_START/STOP notifications from MprFromFile as it was working
in the sipxtapi-media-update branch...
