Hi,
I mapped an CUeglFrame
from a NvBufSurface
as described here.
I have verified that the frameType
is CU_EGL_FRAME_TYPE_PITCH
and that cuFormat
is CU_AD_FORMAT_UNSIGNED_INT8
. This brings me to the conclusion, that I need to get the data from pPitch
as uint8_t
.
I want to access the pPitch data, but I get a SIGSEGV as soon as I try to access it.
This is the code to access it egl_current_frame is the CUeglFrame variable used here:
g_print("Data 0: %d\n", static_cast<uint8_t *>(egl_current_frame.frame.pPitch[0])[0]);
Is there more documentation on how to access this data?
My goal is to use this data in a custom cuda kernel to do calculations on.
