如何在HTML5视频上设置缩略图?
有没有办法在HTML5视频上设置缩略图?我想在播放之前先看一些图片。我的代码如下所示: <video width="470" height="255" controls> <source src="video.mp4" type="video/mp4"> <source src="video.ogg" type="video/ogg"> <source src="video.webm" type="video/webm"> <object data="video.mp4" width="470" height="255"> <embed src="video.swf" width="470" height="255"> </object> </video> 谢谢!
