It seems gstreamer doesn’t have plugin nvstreammux. The question is how to install this plugin, I searched around didn’t figure out yet. I installed all the packages with JetPack 4.4 and SDKmanager 1.1, isn’t that supposed to install everything needed for deepstream 5.0 applications?
Can you find nvstreammux plugin?
gst-inspect-1.0 /usr/lib/aarch64-linux-gnu/gstreamer-1.0/deepstream/libnvdsgst_multistream.so
If you choose install deepstream by sdkmanager, it will automatically install the package needed.
Thanks @Amycao. I do install deepstream 5.0 by sdkmanager 1.1, the nvstreammux library is there, yet the date is not the installation date, it seems the date when the plugin was generated by nvidia?
Nothing with ‘dmesg | grep -i gpu’, below is what I observed in /var/log/syslog/. It seems the gpu card was not initialized properly. This is TX2 development kit, it’s supposed to be supported by the kernel in JetPack4.4, right?

I think the root cause to this issue is that the GPU card is broken. I even tried flashing JetPack 4.2.3 to this TX2, it got the same error, failed to initialize the GPU card.

Don’t know how easy the TX2 dev kit may get broken.
Can you do one more test to try with Jetpack 3.3? it’s an earlier jetpack version. I flashed with this version, cuda sample work well, if your device still can not initialize GPU properly, then it should be GPU broken.
