Video Raw Data Frame Colors Issue

As a brief context, I am trying to get video frames from Zoom Video SDK and feed them into Mediapipe Hands model as bitmaps.
However, I noticed that the conversion from the yuv buffers to bitmaps is resulting in grayscale bitmap images with green and pink spots [please find a screenshot below]

the method I’m using for conversion is the following:

fun ZoomVideoSDKVideoRawData.toBitmap(): Bitmap? {
    val width = streamWidth
    val height = streamHeight
    val yuvBytes = ByteArray(width * (height + height / 2))
    val yPlane = getyBuffer()
    val uPlane = getuBuffer()
    val vPlane = getvBuffer()
    // copy Y
    yPlane.get(yuvBytes, 0, width * height)
    // copy U
    var offset = width * height
    uPlane.get(yuvBytes, offset, width * height / 4)
    // copy V
    offset += width * height / 4
    vPlane.get(yuvBytes, offset, width * height / 4)
    // make YUV image
    val yuvImage = YuvImage(yuvBytes, ImageFormat.NV21, width, height, null)
    // convert image to bitmap
    val out = ByteArrayOutputStream()
    yuvImage.compressToJpeg(Rect(0, 0, width, height), 50, out)
    val imageBytes = out.toByteArray()
    val image = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.size)
    // return result
    return image

any idea why the colors of the resulting bitmap are corrupted?

Which Android Video SDK version?
Zoom Video SDK 1.2.3 Android

Thank you in advance!
