用的sdk版本：
compile 'com.ksyun.media:libksylive-java:2.4.2'
compile 'com.ksyun.media:libksylive-armv7a:2.4.2'

创建两个KSYStreamer对象mPusher1和mPusher2，并且分别设置了GLSurfaceView。
mPusher1.setCameraFacing(CameraCapture.FACING_FRONT)，mPusher2.setCameraFacing(CameraCapture.FACING_BACK)，
然后mPusher1.startCameraPreview()的时候显示第1个预览画面
再调用mPusher2.startCameraPreview()的时候显示第2个预览画面，但是第1个预览画面卡住了。

我直接用安卓原生的方法可以同时开启两个摄像头预览。

这种场景我们还未测试，后续我们看下。

你那边有错误log输出么？

我们验证了下，SDK目前为了健壮性的考虑，暂不支持同时开启多个camera，后续我们会考虑改进这块的逻辑，保证健壮性的前提下支持多camera输出。
