async def main():
  chat = LiveChatAsync(　  
    video_id, 
    callback = func,

Data Format

This processor saves chat data as text of JSON lines. for example...

{"addChatItemAction": {"item": {"liveChatTextMessageRenderer": {"message": {"runs": [{"text": ...}\n
{"addChatItemAction": {"item": {"liveChatPaidMessageRenderer": {"id": "xxx", "timestampUsec": ...}\n
{"addChatItemAction": {"item": {"liveChatTextMessageRenderer": {"message": {"runs": [{"text": ...}\n

The entire file cannot be imported as one JSON file. You need to fetch and parse the JSON line by line.
