rotate screen on the sink device.

[kkangs]

when using normally (not fix), screen like pressed side by side.
(Source : Nexus 4(left img), Sink : Galaxy Nexus(right img), Screen : Vertical)

i want to display the original image(display) when portrait mode.
e.g. sink Nexus5, source Nexus5 -> like equally mode(portrait or landscape) wanna equal image display!

but, now when rotating a screen, it's equall mode. how to fix?

// Sink side modify

/frameworks/native/libs/gui/GLConsumer.cpp

status_t GLConsumer::updateAndReleaseLocked(const BufferQueue::BufferItem& item)
{
    status_t err = NO_ERROR;

// ...

    // for Miracast Sink, screen rotation
    BufferQueue::BufferItem newrot;
    newrot.mTransform = item.mTransform;
    if (mName == "A Sink Surface") {

// ...

        if (mSinkRotate) {
            newrot.mTransform = item.mTransform | 0x04; //
/system/core/include/system/graphics.h HAL_TRANSFORM_ROT_90    = 0x04,
            //ST_LOGW("updateAndReleaseLocked() Force
Transform::ROT_90 [%d, %d]", mSlots[buf].mGraphicBuffer->getWidth(),
mSlots[buf].mGraphicBuffer->getHeight());
        }

        // add this
        newrot.mScalingMode = NATIVE_WINDOW_SCALING_MODE_SCALE_CROP;
        ST_LOGW("updateAndReleaseLocked() item.mScalingMode[%d, %d]",
item.mScalingMode, newrot.mScalingMode);
    }
   // /system/core/include/system/window.h
   //NATIVE_WINDOW_SCALING_MODE_FREEZE           = 0,
   //NATIVE_WINDOW_SCALING_MODE_SCALE_TO_WINDOW  = 1,
   //NATIVE_WINDOW_SCALING_MODE_SCALE_CROP       = 2,
   //NATIVE_WINDOW_SCALING_MODE_NO_SCALE_CROP    = 3,

    // Update the GLConsumer state.
    mCurrentTexture = buf;
    mCurrentTextureBuf = mSlots[buf].mGraphicBuffer;
    mCurrentCrop = item.mCrop;
    //mCurrentTransform = item.mTransform;
    mCurrentTransform = newrot.mTransform; // control rotation
    //mCurrentScalingMode = item.mScalingMode;
    mCurrentScalingMode = newrot.mScalingMode; // control scaling // add this

this works only Source side resolution 800x480
