Pychromecast 脚本不再投射到屏幕

Question

我有一个小的 python 脚本，它应该投射任何提供的媒体文件并在我指定的任何设备上显示它。前几天它运行得很好，但是在第二天早上进行了一些测试后，脚本不再投射。我的终端中没有弹出任何运行时错误，Visual Studio Code 的问题选项卡中也没有任何陈述的问题。因此，除了查看代码以查看我是否有不属于的东西之外，我不太确定我可以提供哪些其他信息会有帮助。

import time
import pychromecast

#List chromecasts on the network, but don't connect
services, browser = pychromecast.discovery.discover_chromecasts()
#print(*services, sep='\n')
#print(browser, sep='\n')
#Shut down discovery
pychromecast.discovery.stop_discovery(browser)

#Discover and connect to chromecasts named Waiting Area TV
chromecasts, browser = pychromecast.get_listed_chromecasts(friendly_names=['Atlas Conference TV'])

#print(chromecasts)
#print('\n')
#print(browser)
#print('\n')
#print([cc.name for cc in chromecasts])

for cast in chromecasts:
    # Start worker thread and wait for cast device to be ready
    cast.wait()
    #DeviceStatus(friendly_name='Atlas Conference TV', model_name='Chromecast', manufacturer='Google Inc.', uuid=UUID('df6944da-f016-4cb8-97d0-3da2ccaa380b'), cast_type='cast')

    print(cast.status)
    #CastStatus(is_active_input=True, is_stand_by=False, volume_level=1.0, volume_muted=False, app_id='CC1AD845', display_name='Default Media Receiver', namespaces=['urn:x-cast:com.google.cast.player.message', 'urn:x-cast:com.google.cast.media'], session_id='CCA39713-9A4F-34A6-A8BF-5D97BE7ECA5C', transport_id='web-9', status_text='')
    mc = cast.media_controller
    mc.play_media('http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4', 'video/mp4')
    print(mc.status)
    #MediaStatus(current_time=42.458322, content_id='http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4', content_type='video/mp4', duration=596.474195, stream_type='BUFFERED', idle_reason=None, media_session_id=1, playback_rate=1, player_state='PLAYING', supported_media_commands=15, volume_level=1, volume_muted=False)

time.sleep(20)

for cast in chromecasts:
    cast.wait()
    mc = cast.media_controller
    mc.stop()
    print('\n')
    print(f"Cast: [{cast}]... \nShould be playing... \ntime to stop it.")
    print(cast.status)
    time.sleep(2)
    cast.wait()
    cast.quit_app()
    print(cast.status)
# # Shut down discovery
pychromecast.discovery.stop_discovery(browser)

这是一个老问题，但万一有人再次通过它， 您需要定义您的应用程序 ID 并将其传递给“CastStatus”

import time
import pychromecast
from pychromecast.controllers.receiver import CastStatus

#List chromecasts on the network, but don't connect
services, browser = pychromecast.discovery.discover_chromecasts()
#print(*services, sep='
')
#print(browser, sep='
')
#Shut down discovery
pychromecast.discovery.stop_discovery(browser)

#Discover and connect to chromecasts named Waiting Area TV
chromecasts, browser = pychromecast.get_listed_chromecasts(friendly_names=['Family Room TV'])

#print(chromecasts)
#print('
')
#print(browser)
#print('
')
#print([cc.name for cc in chromecasts])

app_id = '545??????'

for cast in chromecasts:
    # Start worker thread and wait for cast device to be ready
    cast.wait()
    #DeviceStatus(friendly_name='Atlas Conference TV', model_name='Chromecast', manufacturer='Google Inc.', uuid=UUID('df6944da-f016-4cb8-97d0-3da2ccaa380b'), cast_type='cast')

    print(cast.status)
    CastStatus(is_active_input=True, icon_url='', volume_control_type=1, is_stand_by=False, volume_level=1.0,
               volume_muted=False, app_id=app_id, display_name='Default Media Receiver',
               namespaces=['urn:x-cast:com.google.cast.player.message', 'urn:x-cast:com.google.cast.media'],
               session_id='CCA39713-9A4F-34A6-A8BF-5D97BE7ECA5C', transport_id='web-9', status_text='')

    #CastStatus(is_active_input=True, is_stand_by=False, volume_level=1.0, volume_muted=False, app_id='CC1AD845', display_name='Default Media Receiver', namespaces=['urn:x-cast:com.google.cast.player.message', 'urn:x-cast:com.google.cast.media'], session_id='CCA39713-9A4F-34A6-A8BF-5D97BE7ECA5C', transport_id='web-9', status_text='')
    mc = cast.media_controller
    mc.play_media('http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4', 'video/mp4')
    print(mc.status)
    #MediaStatus(current_time=42.458322, content_id='http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4', content_type='video/mp4', duration=596.474195, stream_type='BUFFERED', idle_reason=None, media_session_id=1, playback_rate=1, player_state='PLAYING', supported_media_commands=15, volume_level=1, volume_muted=False)
    time.sleep(10)

time.sleep(20)

for cast in chromecasts:
    cast.wait()
    mc = cast.media_controller
    mc.stop()
    print('

    print(f"Cast: [{cast}]...

time to stop it.")
    print(cast.status)
    time.sleep(2)
    cast.wait()
    cast.quit_app()
    print(cast.status)
# # Shut down discovery
pychromecast.discovery.stop_discovery(browser)
