I’m working around multi-stream processing with jetson, and I used Opencv+Gstreamer using python to decode the frames with HW accelerator, and I used optimal solution for decoding with opencv+gstreamer, but because I connected USB Coral TPU to jetson, I have to copied the decoded frames from NVMM buffer to CPU buffer to USB TPU.
I’ve tested the deepstream samples and I found that the decoder of this SDK don’t use memory. because the NVMM buffer directly connected to GPU processing.
Q1) NVMM buffer is independent of jetson memory?
Q2) CPU buffer is part of jetson memory?
Q3) How I can access to NVMM buffer for GPU processing without copy to CPU buffer?
