首帧非常满是因为avplayer得拿到metadata后才能播放，也就是刚刚开始那个range(0, 2)但是如果metadata这部分信息不在视频流头部，avplayer会假设在尾部请求尾部，如果都不在会一直request取metadata。最好的办法是该url的视频用特殊的视频编码器把metadata放在最头部，播放会最快

打不开的错误，可以断点看看 downloader 里面 dataTask 都报啥错了。
首帧很慢的问题，用这个 commit 21926ff 试试，看还有没有问题。
最好是视频 url 能发一下，好排查问题

这个视频编码器的处理， 需要使用哪个？ 在服务端做吗？求指教， 谢谢🙏
