In the DeepStream plugin sample, there are 2 NvBuffers
The first came from a GstBuffer using ExtractFdFromNvBuffer.
The other is created using NvBufferCreateEx
NvBufferMemMap works only for the one created using NvBufferCreateEx.
For the one that came from the GstBuffer using ExtractFdFromNvBuffer, NvBufferMemMap returns OK
but the memory content is wrong - I even tried NvBufferMemSyncForCpu. Only thing that
worked is NvBuffer2Raw.
Is there any part of the documentation that can explain this?
