NV12 saving by EGLStream::IImageHeaderlessFile is different than saving from dma buffer

[Hnil.DN]

Hi Dane,

Thanks for the reply.
I tested the original nvbuf_util library and it doesn’t have problem with copying buffer. I did the test similarly to Copying YUV420 buffer using NvBufferTransform cause pixel value change - #7 by kazunori.kimura

However, the my issue above persists even with the patched library.
