我谨以动态方式添加文字,以读作超文本5。 目前,通过闪电和通过闪电在一定时间间隔内预期的变量来实现。 超文本5中的对应(如果有的话)是什么? 是否有任何实例?
You could render the frames to a canvas, and then add the text from there. Here is an example http://www.craftymind.com/2010/04/20/blowing-up-html5-video-and-mapping-it-into-3d-space/

The equivalent for this would be the text track api or the track element. Which gives you multiple things. A cuechange event for scripting (kind=metadata), using the text track api to directly render subtitles into the video (kind=subtitles).
如上文所解释,“超文本”5 给你以“电传”和“标志”来实现这一点。 目前只有Safari支持这一点。 http://jsfiddle.net/trixta/QZJTM/“rel=“nofollow” 例如,在上使用聚氯乙烯。
