Hi,
although I refered to the manual, I worry about the audio file to be played
with first seconds cut.
Sometimes only 2 sec are cut and sometimes even 5 or more are missing at the
beginning.
It depends on the time that it takes for "reading"/preparing the wave file.
That's the way I implement it in MyCallCallback class:
> def on_media_state(self):
> if self.call.info().media_state == pj.MediaState.ACTIVE:
> global player_id
> call_slot = self.call.info().conf_slot
> #pj.Lib.instance().conf_connect(call_slot, 0)
> #pj.Lib.instance().conf_connect(0, call_slot)
> print "one more..."
> wfile = wave.open("play.wav")
> time = (1.0 * wfile.getnframes ()) / wfile.getframerate ()
> print str(time) + "ms"
> wfile.close()
> player_id = lib.create_player("play.wav",True)
> lib.conf_connect(lib.player_get_slot(player_id), current_call.info
> ().conf_slot)
> print "audio wait...",time
> sleep(time*3)
> print "audio over now..."
> lib.conf_disconnect(lib.player_get_slot(player_id),
> current_call.info().conf_slot)
> lib.player_destroy(player_id)
> print "!!!destroyed lib + player"
>
And it works without error messages, but as described above, it does not
play the file from the beginning :-(
It "sleeps" as expected after this output (log level: 4) and after some
seconds it starts playing the audio for the caller:
> 20:17:58.039 strm0x89515ec VAD temporarily disabled
> 20:17:58.039 strm0x89515ec Encoder stream started
> 20:17:58.039 strm0x89515ec Decoder stream started
> 20:17:58.039 pjsua_media.c Media updates, stream #0: PCMA (sendrecv)
> one more...
> 12.631625ms
> 20:17:58.039 wav_player.c File player 'play.wav' created:
> samp.rate=8000, ch=1, bufsize=4KB, filesize=202KB
> 20:17:58.040 conference.c Port 2 (play.wav) transmitting to port 1 (
> sip:101 at 192.168.1.99 <sip%3A101 at 192.168.1.99>)
> audio wait... 12.631625
>
And just to be sure there is no error in another part of the .py, that's how
i catch the call-in:
> def on_incoming_call(self, call):
> global current_call, player_id
> if current_call:
> print "Busy...",current_call
> print "dont mind..."
> call.answer(486, "Busy")
> return
> print "Incoming call from ", call.info().remote_uri
> current_call = call
> call_cb = MyCallCallback(call)
> call.set_callback(call_cb)
> call.answer(200)
>
Looking fwd. to advice from you.
Thanks a lot and have a nice day
