After going thru pygui code, I modified the example as below. I have two issues
1. In each call back function, at the end I need to add a dummy raise exception, else it misbehaves. For example, if I comment dummy exception of onIncomingCall, incoming call will get disconnected with 500 error. In pyGUI, it looks like ttk.master.after()
plays critical role. As I am trying it in a headless server (mean only cli), not sure how to handle it?
2. When I try to use createRecorder getting following error
-----------------------------------------------
Traceback (most recent call last):
File "pjsua2_cli_demo.py", line 33, in onCallState
self.recorder.createRecorder('xxxxxxxxxxxxxx/PJSUA2/example/pygui/file.wav');
File "xxxxxxxxxxxxxxxx/.local/lib/python3.6/site-packages/pjsua2.py", line 4110, in createRecorder
return _pjsua2.AudioMediaRecorder_createRecorder(self, file_name, enc_type, max_size, options)
NotImplementedError: Wrong number or type of arguments for overloaded function 'AudioMediaRecorder_createRecorder'.
Possible C/C++ prototypes are:
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int,pj_ssize_t,unsigned int)
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int,pj_ssize_t)
pj::AudioMediaRecorder::createRecorder(pj::string const &,unsigned int)
pj::AudioMediaRecorder::createRecorder(pj::string const &)
------------------------------------------------
Note: I am having issues in replying to same thread. So opened a Stakeworkflow query for same. If this time also, it created to new thread, I will continue to use stakeworkflow
