使用使用libstagefrighthw.so显示yuv数据问题，能成功创建VideoRenderer *mTarget对象,
但是在mTarget->render(yuv, frame_len, NULL);//图像为720p的，程序直接挂在render函数中的
LOGE("Doing a memcpy. Report this issue.");
memcpy(mOverlayAddresses[mIndex]->pointer(), data, size);
此memcpy代码中。
mOverlayAddresses[mIndex]->pointer() 内存大小是足够大

把frame_len设置成1280(720p的,如果是640*480则改为640，相应的上面其他参数也更改)，可以出现闪烁的图像。程序不会挂。
请问是否是有些什么设置没有设置？
请求给为给点意见和建议，或者一起讨论下！
