提取出分辨率、音质等信息最好的音视频流。
Args:
**以下参数仅能在音视频流分离的情况下产生作用，flv / mp4 试看流 / html5 mp4 流下以下参数均没有作用**
video_max_quality (VideoQuality) : 设置提取的视频流清晰度最大值，设置此参数绝对不会禁止 HDR/杜比. Defaults to VideoQuality._8K.
audio_max_quality (AudioQuality) : 设置提取的音频流清晰度最大值. 设置此参数绝对不会禁止 Hi-Res/杜比. Defaults to AudioQuality._192K.
video_min_quality (VideoQuality, optional) : 设置提取的视频流清晰度最小值，设置此参数绝对不会禁止 HDR/杜比. Defaults to VideoQuality._360P.
audio_min_quality (AudioQuality, optional) : 设置提取的音频流清晰度最小值. 设置此参数绝对不会禁止 Hi-Res/杜比. Defaults to AudioQuality._64K.
video_accepted_qualities(List[VideoQuality], optional): 设置允许的所有视频流清晰度. Defaults to ALL.
audio_accepted_qualities(List[AudioQuality], optional): 设置允许的所有音频清晰度. Defaults to ALL.
codecs (List[VideoCodecs]) : 设置所有允许提取出来的视频编码. 在数组中越靠前的编码选择优先级越高. 此项不会忽略 HDR/杜比. Defaults to [VideoCodecs.AV1, VideoCodecs.AVC, VideoCodecs.HEV].
no_dolby_video (bool) : 是否禁止提取杜比视界视频流. Defaults to False.
no_dolby_audio (bool) : 是否禁止提取杜比全景声音频流. Defaults to False.
no_hdr (bool) : 是否禁止提取 HDR 视频流. Defaults to False.
no_hires (bool) : 是否禁止提取 Hi-Res 音频流. Defaults to False.
Returns:
List[VideoStreamDownloadURL | AudioStreamDownloadURL | FLVStreamDownloadURL | HTML5MP4DownloadURL | None]: FLV 视频流 / HTML5 MP4 视频流 / 番剧或课程试看 MP4 视频流返回 `[FLVStreamDownloadURL | HTML5MP4StreamDownloadURL | EpisodeTryMP4DownloadURL]`, 否则为 `[VideoStreamDownloadURL, AudioStreamDownloadURL]`, 如果未匹配上任何合适的流则对应的位置位 `None`
