How to use ScriptIntrinsicYuvToRGB (converting byte[] yuv to byte[] rgba)

Question

I have byte[] yuvByteArray (540x360 image captured from Camera.PreviewCallback.onPreviewFrame method and dumped into assets/yuv.bin fi

Answer 1

Our internal test app uses the following sequence to create the YUV allocation.

    tb = new Type.Builder(mRS, Element.createPixel(mRS, 
              Element.DataType.UNSIGNED_8, Element.DataKind.PIXEL_YUV));
    tb.setX(mWidth);
    tb.setY(mHeight);
    tb.setYuvFormat(android.graphics.ImageFormat.NV21);
    mAllocationIn = Allocation.createTyped(mRS, tb.create(), Allocation.USAGE_SCRIPT);

Then inside the callback that new YUV data is available do

    mAllocationIn.copyFrom(theYuvByteArray);
