根据YouTube docs的showinfo参数:
Setting the parameter's value to 0 causes the player to not display information like the video title and uploader before the video starts playing.
那么，为什么标题仍显示在下面的代码中？请注意，我没有使用其他任何可能引起冲突的参数(例如
modestbranding)。<iframe src="https://www.youtube.com/embed/fVH2lJeZVGU?showinfo=0">最佳答案
Showinfo不能那样工作。
请参阅已定义的方法帮助:
Setting the parameter's value to 0 causes the player to not display information like the video title and uploader before the video starts playing. If the player is loading a playlist, and you explicitly set the parameter value to 1, then, upon loading, the player will also display thumbnail images for the videos in the playlist. Note that this functionality is only supported for the AS3 player.
关于iframe - YouTube showinfo参数不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45508613/
