I’m trying to get the gpu memory buffer from my gstreamer command.
In my source code, I’m using below command.
str_gst_launch = “v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080,format=UYVY !
nvvidconv ! video/x-raw(memory:NVMM),width=512,height=512,format=BGRx ! appsink name=mysink”;
As I know, my command returns gpu memory buffer. So I tried to dump it by cudaMemcpy.
CUDA_CHECK(cudaMemcpy(dst, src_from_gstreamer, (unsigned char) * 512*512 * 4, cudaMemcpyDeviceToHost));
But I could see ‘[ERROR] CUDA 1’ , when I run cudaMemcpy.
So my question is, can I get the gpu memory buffer from gstreamer? And can I pass it to cuda process, without cpu memcpy?
Thanks in advance.
