// 由于采用自动显示（在AnyChatCoreSDK.InitSDK时设置了AnyChatCoreSDK.BRAC_FUNC_VIDEO_AUTODISP），所以屏蔽通过回调的方式显示视频，效率更高
// 如果希望对视频进行处理，则可以设置AnyChatCoreSDK.BRAC_FUNC_VIDEO_CBDATA，去掉AnyChatCoreSDK.BRAC_FUNC_VIDEO_AUTODISP，然后开放下面的代码即可
// 有关AnyChat自动显示和回调显示的区别可参考：http://www.anychat.cn/faq/index.php?action=artikel&cat=2&id=196&artlang=zh
