UnsupportedImageFormatException

[gordinmitya]

Yuv format is not supported: Yuv(resource=androidx.camera.core.SettableImageProxy@f251aa8, width=864, height=480, y=Plane(buffer=java.nio.DirectByteBuffer[pos=0 lim=430048 cap=430048], pixelStride=1, rowStride=896), u=Plane(buffer=java.nio.DirectByteBuffer[pos=0 lim=215007 cap=215007], pixelStride=2, rowStride=896), v=Plane(buffer=java.nio.DirectByteBuffer[pos=0 lim=215007 cap=215007], pixelStride=2, rowStride=896))

Hello, can you suggest what is the possible cause for this error? I noticed strange values width = 864 but rowStride = 896, may be this is the reason.

@sellmair can you provide some info about these lines:

operator fun YuvImage.Factory.invoke(yuv: Yuv): YuvImage {
    // YuvImage.kt
    if (yuv.y.pixelStride != 1 || yuv.y.rowStride != yuv.width) { // <-- here
        throw UnsupportedImageFormatException(yuv)

// Yuv+defrag.kt
fun Yuv.defrag(): Yuv {
    val start = System.currentTimeMillis()

    require(y.pixelStride == 1)
    require(y.rowStride == width) // <--- and here

In documentation it's not stated that y.rowStride == width is always guaranteed. Why don't we just remove them and let defragPlanePadding do the job?

Thanks for creating the issue, I have exactly the same problem using a Google Pixel 2.

@m-rm I fixed it with commenting two lines I mentioned above

But that's not the best fix, because it will move all the pixels from NV21 format to YUV420. I'm going to create more efficient library – will post update here.

you tried the camera2 API ?

[gordinmitya]

with camera api 1 we don't need that – there's ready to use byte[]

@LiorA1 @m-rm made a correct implementation with unit tests, demo app, benchmarks https://github.com/gordinmitya/yuv2buf
