Hi Folks, Where can we know more about NVMM memory, in terms of its architectural location on Tegra SoC or external DDR ? Would like to understand where buffer are created when we do - Gstreamer CAPS like - filtercaps = gst_caps_from_string("video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)30/1 "); I need to transfer contents of Gstreamer - GstBuffer to opencv CV::Mat. While doing so I run into problems/issues related to NVMM (I think). He…

For instructions on how to use the nvvidconv with appsink.

Fabian
