Sorry i was busy working something else last few days. I have started going
through the code before changes. Before I go and start making mess in
stable code I want to be clear on what I am doing.
In prerecorded application I think following lines are responsible to
finally play a file.
1- file->open() ---- Open the file of correct codec as per payload-type.
2- setOutput(file); ---- It i think copies the buffer into session to
finally play.
3- AmSession::onSessionStart(); ---- This starts playing the file.
Now the real reason i want to implement this in playfile() function of
DSM.cpp because I want to use playfile_precoded (Lets say) multiple times
(I want to play files like "You.g729", then "have.g729" then
"Hundred.g729"...and so on.
If we maky a playfile_precoded() it will be like this ...
{
AmPrecodedFileInstance* file =
file_def->getFileInstance(RTPStream()->getPayloadType());
if (!file) {
ERROR("no payload\n");
}
if (!file || file->open()) {
ERROR("PrecodedDialog::onSessionStart: Cannot open file\n");
dlg->bye();
setStopped();
return;
}
setOutput(file);
}
But if i call this function multiple times wouldn't it set buffer to last
file?.. There should be some kind of queue to really work it out (Or may be
there already is)
Also I need to implement Stop Function?
