Unity5.6版本添加了一个新的组件VideoPlayer，这个组件是用来播放视频，这个解决了之前用movietexture播放视频，只能在PC端使用的问题，因为刚出来，可能还有一些问题，今天我要说的是怎样将视频显示在UGUI上，我用了两种方法，一种是在RawImage显示，一种是在Image上显示，这两个有什么区别，一个就是直接放Texture就可以，一个是要把Texture转成Sprite，刚开始的思路是将Texture强转为Texture2D，但是Unity运行的时候会报错，后来想到了用RenderTexture来获取Texture2D，在转成Sprite。好了，下面就是代码。

代码就这些，其实也没多复杂。只要将上面的代码拖到UGUI的Image或者RawImage上选择相应的模式就能进行视频播放了。文章源自大腿Plus-https://www.zhaoshijun.com/archives/584

目前来说这个组件还是很好用的，但是在某些情况下，会有莫名其妙的问题。等遇到了再说吧。文章源自大腿Plus-https://www.zhaoshijun.com/archives/584

大长腿,刚刚用了你这个方法,打包到手机上不能播放,貌似是找不到资源,直接一篇空白

@ 杰之诺风 你电脑装QuickTime Player播放器了吗，没有的话装一个，把视频重新导进去

怎么在安卓手机上播放直接黑屏啊

@ 一半是记忆。一半是继续 可能和Unity版本有关系

能进行暂停和播放么
B1
@ 此郎非彼狼 可以，不过要自己写暂停播放的方法
