Description

When downloading video files, especially large ones, it often happens that the downloaded file size is 0, or the downloaded file size is incorrect, or the download is incomplete.

Steps to reproduce

while(True):
    file = await tiqu_user_app.download_media(message = msg)
    if not os.path.exists(file):
        continue
    if os.path.getsize(file) == 0 or (msg.video and os.path.getsize(file) != msg.video.file_size):
        if msg.video and os.path.getsize(file) != msg.video.file_size:
            print(f"download fail，{os.path.getsize(file)}-{msg.video.file_size}")
        elif os.path.getsize(file) == 0
            print(f"retry:{retry}")
    else:
        break
