如何使用 telethon 下载视频

Question

我正在研究 telethon download_media 和 _download_document 从电报下载视频的方法。我的代码是这样的：

def callback(update): 
        Channel_Entity = client.get_entity(Channel_List) #Get specific Channel information

        file_name = str(document_id)+'.mp4'
        current_path = os.getcwd()
        file_path_gif = current_path+'/media/gif'
        file = open(os.path.join(file_path_gif,file_name),'wb')

        if isinstance(update, UpdateNewChannelMessage): #Check Update message in channel
            if update.message.to_id.channel_id == Channel_Entity.id:

                client._download_document(update.message.media, file, update.message.date, progress_callback=None)

                # OR 

                client.download_media(update.message, file, progress_callback=None)

但是当视频发送到频道并使用此代码下载时，视频无法播放并且播放器打印此消息：无法渲染文件。此代码适用于图像和 gif 文件，但不适用于视频文件。我该怎么办？

希望这段代码对您有所帮助。我用的是Telethon V0.19，但是之前的版本都差不多。

from telethon import TelegramClient

api_id = XXXXXXX
api_hash = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXX'
phone_number = '+98XXXXXXXXX'
################################################
channel_username = 'tehrandb'
################################################

client = TelegramClient('session_name',
                    api_id,
                    api_hash)

assert client.connect()
if not client.is_user_authorized():
    client.send_code_request(phone_number)
    me = client.sign_in(phone_number, input('Enter code: '))

# ---------------------------------------
msgs = client.get_messages(channel_username, limit=100)
for msg in msgs.data:
    if msg.media is not None:
        client.download_media(message=msg)
