关于win8.1平板前后摄像头调用的问题

qingfengtech · 发表于 2016-7-7 21:35:23

三星win8.1平板摄像头在控件设备列表里可以显示，后置型号为OV8830，前置是OV2270(这个没记清)
程序调用黑屏，可以调用出画质调节，切换摄像头也均无反应，用一个第三方的摄像头美化软件YouCam 可以在设备列表里列出这个虚拟摄像头，可以调用，但这个软件只能调用后置摄像头，无法调用前置的
注 win8.1自带的相机是可以调用前后摄像头的，我的程序在win7平台调用USB摄像头完全正常，切换正常

请官方核实，如何解决？

补充一点
anychatsdk.ini不能写出videocapture设备， audiocapture是正常的，手工添加后，程序也能知道选的是添加的那个头，但仍然是黑屏

您好，anychatsdk.ini是Anychat系统的参数控制写出来的；试试使用QQ视频，前置摄像头是否正常？

您好，这是由于获取摄像头失败导致的。请问有试过其他第三方软件能获取到摄像头吗？

您好，请将打开摄像头失败后的日志文件（BRAnyChatCore.log）附上来，我们帮您分析一下，谢谢。

QQ可以正确识别后置摄像头，前置也不能识别
anychat可以识别到两个头，但那个都不能激活

QQ可以正确识别后置摄像头，前置也不能识别

从您的测试情况，以及日志输出的信息来分析，可能是这台平板的摄像头驱动存在一定的特殊之处，没有兼容标准的DirectShow体系。

AnyChat、QQ都是兼容DirectShow体系的，如果QQ也不能打开该摄像头，则AnyChat也是无法打开该摄像头的，除非由厂家提供相关的API接口做定制开发。
