VideoPlayer Class¶
Description¶
VideoPlayer是视频播放类。
EasyAR支持普通的视频、透明视频和流媒体播放。视频内容会被渲染到传入setRenderTexture的texture上。
该类只支持OpenGLES2的texture。
由于依赖于OpenGLES，本类的所有函数(包括析构函数)都必须在单个包含OpenGLES上下文的线程中调用。
当前版本要求宽高均为16的倍数。
支持的视频文件格式
Windows: Media Foundation兼容格式，安装额外的解码器可以支持更多格式，请参考 Supported Media Formats in Media Foundation ，不支持DirectShow
Mac: 不支持
Android: 系统支持的格式，请参考 Supported media formats 。
iOS: 系统支持的格式，当前没有有效的参考文档

setVideoType¶
设置视频类型。如果没有手动设置，将默认为普通类型。这个方法需要在open之前调用。

- C++17
void setVideoType(VideoType videoType)
- C++03

setRenderTexture¶
传入用来显示视频的texture到播放器。这个方法需要在open之前调用。
- C
void easyar_VideoPlayer_setRenderTexture(easyar_VideoPlayer * This, easyar_TextureId * texture)
- C++17
void setRenderTexture(std::shared_ptr<TextureId> texture)

open¶
从 path 打开视频。
path 可以是本地视频文件（path/to/video.mp4）或url（http://www.../.../video.mp4）。storageType 表示path的类型。详细描述参见 StorageType 。
这个方法是异步的方法。open可能会花一些时间才能完成。如果你希望知道视频打开的结果或播放中的状态，需要处理callback数据。callback会在callbackScheduler对应的线程中被调用。你可以在回调中检查打开是否成功结束并在成功打开之后开始播放。
