我正在尝试使用 mplayer 播放 youtube 流。在运行时mplayer -cache 2048 https://www.youtube.com/watch?v=USUA_1WVM8I，我得到以下输出，并且视频根本无法播放。

任何其他 YouTube 视频也会发生同样的情况。
从输出来看，TLS 库似乎存在一些问题，但我用 VLC 尝试了相同的视频，它们播放得很好。如何使用 mplayer 解决这个问题？
答案1
mplayer 不支持 HTTPS 协议。因此，您应该将 mplayer 与 youtube-dl 结合使用，将视频下载到帧缓冲区中然后播放。
像这样：
curl --ciphers RC4-SHA "$(youtube-dl -g http://www.youtube.com/watch?v=XEVlyP4_11M)" | mplayer -
