Camerax Analyzer imageProxy to Bitmap conversion gives the greenish image.

[Ramesh Sambu]

I used the below code to convert the imageProxy.In production getting the greenish images for some devices.Please help me to do in the right direction and minimua

private fun imageProxyToBitmap(image: ImageProxy): Bitmap? {
val yBuffer = image.planes[0].buffer // Y
val vuBuffer = image.planes[2].buffer // VU
val ySize = yBuffer.remaining()
val vuSize = vuBuffer.remaining()
val nv21 = ByteArray(ySize + vuSize)
yBuffer.get(nv21, 0, ySize)
vuBuffer.get(nv21, ySize, vuSize)
val yuvImage = YuvImage(nv21, ImageFormat.NV21, image.width, image.height, null)
val out = ByteArrayOutputStream()
yuvImage.compressToJpeg(Rect(0, 0, yuvImage.width, yuvImage.height), 50, out)
val imageBytes = out.toByteArray()
return BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.size)
}

Hi,

Could you check on these devices, the image.width is equal to image.getPlanes()[0].getRowStride() or not? 

Otherwise, you need to use rowStride instead.

Best,

You could refer to this utility function and try to see if it works.
