Incorrect image converting YUV_420_888 into Bitmaps under Android camera2

Question

I’m trying to convert YUV_420_888 images into bitmaps, coming from the camera2 preview. But the output image has incorrect colors.

Next is the test code I’m running

Answer 1

There is no direct way to copy a YUV_420_888 camera frame in into an RS Allocation. Actually, as of today, Renderscript does not support this format.

If you know that, under the hood, your frame is NV21 or YV12 - you can copy the entire ByteBuffer to an array and pass it to RS Allocation.
