youtube视频中的CPN是什么
What is CPN in youtube video
点击人民币后出现的上下文菜单有一个名为Stats for nerds的选项，之后左上角出现另一个菜单。
关联的参数之一是 CPN。
这是什么意思？
官方回答on reddit thread:
CPN is just a string we use to identify the playback; if you have
problems with the playback, developers can use it to look up log/stats
information on the playback so we can figure out what went wrong.
并在同一个 comment tree:
Yes, CPN is just a unique playback ID, computed on the client; stands
for "Client Playback Nonce."
