Вызов pj_thread_register из python

0 голосов
/ 30 мая 2020

Я пытаюсь использовать pjsip через pjsua2 в python. У меня проблема с потоками. 

import pjsua2 as pj
import threading

# pjsua2 test function
def pjsua2_test():
  # Create and initialize the library
  ep = pj.Endpoint()
  ep.libCreate()

if __name__ == "__main__":
  pjsuadaemonthread = threading.Thread(name='PJSUA',
                      target=pjsua2_test)
  pjsuadaemonthread.start()
  ep = pj.Endpoint()
  ep.libHandleEvents(10)

Я получаю эту ошибку: 

python3: ../src/pj/os_core_unix.c:692: pj_thread_this: Assertion `!"Calling pjlib from unknown/external thread. You must " "register external threads with pj_thread_register() " "before calling any pjlib functions."' failed.

Как мне вызвать pj_thread_register () из python?

Это синтаксис pj_thread_register (): 

ep.libRegisterThread('PJSUA')

К сожалению, даже если вы вызываете libRegisterThread, он не кажется совместимым с python threading.

Я думаю, это потому, что pjsip внутренне использует потоки типа pj_thread_t, а python потоки не относятся к типу pj_thread_t.

Для получения дополнительной информации взгляните на Endpoint :: libRegisterThread в исходном коде pjsip.

Однако, если вы просто хотите запустить pjsip в другом потоке, приведенный ниже код может помочь. Он запускает pjsip в фоновом потоке с именем «PJSUA-THREAD». Ключ в том, чтобы вызвать libCreate () в другом потоке, как я делаю ниже. 

'''Tests running PJSUA2 in a different thread'''
import logging
import threading
import pjsua2

date_fmt = '%Y-%m-%d,%H:%M:%S'
log_format = "%(levelname)s %(asctime)s.%(msecs)03d %(threadName)s %(name)s.%(funcName)s %(message)s"
logging.basicConfig(format=log_format, datefmt=date_fmt, level=logging.DEBUG)

_logger = logging.getLogger(__name__)

THREAD_NAME = "PJSUA-THREAD"

def main():
    _logger.debug("entered main()")
    pjsuadaemonthread = threading.Thread(name=THREAD_NAME, target=pjsua2_test)
    pjsuadaemonthread.start()
    _logger.debug("thread started")
    pjsuadaemonthread.join()

# pjsua2 test function
def pjsua2_test():
    # NOTE: PjSip will initialize and run on PJSUA-THREAD, see logs
    ep = pjsua2.Endpoint()
    ep.libCreate()
    _logger.debug("after libCreate()")
    ep_cfg = pjsua2.EpConfig()
    ep_cfg.uaConfig.mainThreadOnly = False
    ep_cfg.uaConfig.threadCnt = 1
    ep.libInit(ep_cfg)
    _logger.debug("after libInit(ep_cfg)")
    ep.libStart()
    _logger.debug("after libStart()")
    iter_count = 0
    event_count = 0
    while iter_count < 10:
        event_count += ep.libHandleEvents(10)
        _logger.debug("iter_count %d (%d events processed)", iter_count, event_count)
        iter_count += 1
    ep.libDestroy()
    _logger.debug("after ep.libDestroy()")

if __name__ == "__main__":
    main()
    _logger.debug("after main()")

Вот вывод журнала. Вы можете видеть, что pjsip работает в потоке PJSUA-THREAD.
