在浏览了PJSIP库站点中提供的pygui代码之后,我修改了下面的示例。我有两个问题
在每个回调函数的末尾,我需要添加一个虚拟的raise异常,否则它会行为错误。例如,如果我注释onIncomingCall的伪异常,传入的调用将断开连接,并出现500个错误。在pyGUI,它看起来像ttk.master.after.之后()起关键作用。当我在无头服务器(仅指cli)中尝试时,不知道如何处理它?
当我尝试创建记录器时,出现以下错误:
Traceback (most recent call last): File "pjsua2_cli_demo.py", line 33, in onCallState self.recorder.createRecorder('xxxxxxxxxxx/PJSUA2/example/pygui/file.wav'); File "xxxxxxxxxxx/.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 &)

在编译pjsuaswig之前,将以下行添加到pjsipapps/src/swig文件夹中的pjsua2.i
使用这个额外的函数,您可以创建一个pj_ssize_t类型的变量并将其传递给createRecorder函数。在
