Yuv format is not supported

[zzxjl1]

The problem happens when set the resolution to 2160x1080.

`/**

• Thrown by [YuvImage.Factory.invoke] for non supported yuv formats.
• According to the Android documentation no phone should encounter this exception.

Hi, this bug can be reproduced by using new CameraX library and if you put setTargetResolution method inside your ImageAnalysis. It it really weird, because if setTargetResolution method is not called image.yuv() works perfectly.

I am really sorry but i do not have many time to investigate that bug so in my code i replace it by a lot slower method, but maybe this snippet from stackoverflow will help you:

fun imageToMat(image: Image): Mat {
var buffer: ByteBuffer
var rowStride: Int
var pixelStride: Int
val width = image.width
val height = image.height
var offset = 0
val planes = image.planes
val data = ByteArray(
image.width * image.height * ImageFormat.getBitsPerPixel(ImageFormat.YUV_420_888) / 8)
val rowData = ByteArray(planes[0].rowStride)
for (i in planes.indices) {
buffer = planes[i].buffer
rowStride = planes[i].rowStride
pixelStride = planes[i].pixelStride
val w = if (i == 0) width else width / 2
val h = if (i == 0) height else height / 2
for (row in 0 until h) {
val bytesPerPixel = ImageFormat.getBitsPerPixel(ImageFormat.YUV_420_888) / 8
if (pixelStride == bytesPerPixel) {
val length = w * bytesPerPixel
buffer[data, offset, length]
if (h - row != 1) {
buffer.position(buffer.position() + rowStride - length)
}
offset += length
} else {
if (h - row == 1) {
buffer[rowData, 0, width - pixelStride + 1]
} else {
buffer[rowData, 0, rowStride]
}
for (col in 0 until w) {
data[offset++] = rowData[col * pixelStride]
}
}
}
}
val mat = Mat(height + height / 2, width, CvType.CV_8UC1)
mat.put(0, 0, data)
return mat
}

try { mat = Yuv.rgb(image); // YUV_420_888 to Mat(RGB) } catch (Exception e) { // destory camera activity and start it with another resolution }
After some debuging, i came up with this method and it works fine now.
