先修改buffersize至少为1080*1920那么
到底是frameworks/native/libs/gui/Surface.cpp这个文件修改有效，还是frameworks/native/libs/ui/GraphicBufferAllocator.cpp这个文件修改有效的呢？
需改这个文件：frameworks/native/libs/ui/GraphicBufferAllocator.cpp就有效果了。

下面修改复制的部分内容：
//zcfdebug++<<
                                ALOGE("zcfdebug1 mActiveBuffer->stride is %d", mActiveBuffer->stride);
                                ALOGE("zcfdebug1 mActiveBuffer->height is %d", mActiveBuffer->height);

        if (mActiveBuffer != NULL) {
                                if(mActiveBuffer!=NULL){
                                    uint8_t* img = NULL;
                                        ALOGE("zcfdebug1 here run buf!=NULL && buf->height==1920 && buf->stride ==1920");
                                    mActiveBuffer->lock(GRALLOC_USAGE_SW_WRITE_OFTEN, (void**)(&img));
                                        memcpy(img+960*mActiveBuffer->stride*4,img,mActiveBuffer->stride * 960*4);
                                    mActiveBuffer->unlock();
                                }


        }
//zcfdebug>>++

下面看看开口的大小是那个文件导致的？
1，是frameworks/native/services/surfaceflinger/Layer.cpp这个文件的两处修改导致的？
不是
2，frameworks/native/libs/gui/Surface.cpp是这个文件修改导致的？也不是
3，是frameworks/native/services/surfaceflinger/SurfaceFlinger.cpp这个文件修改导致的？也不是
4，是frameworks/native/services/surfaceflinger/DisplayHardware/HWComposer.cpp这个文件修改导致的吗？

zangcf

已经确认就是HWComposer修改导致的，如果值修改这个地方，会是什么样子的呢？

zangcf

1，frameworks/native/libs/gui/Surface.cpp修改回去
确实和这个文件没有关系
2，frameworks/native/services/surfaceflinger/Layer.cpp改回去
和这个文件确实有关系的？

zangcf

下面试试看修改高度，统一在底层修改如何呢？
