I’m quite new to gstreamer. I tried to install the accelerated GStreamer following the Accelerated GStreamer User Guide.
Then I tried to verify the accelerated version was installed rather than the plain version by running
And here’s what my /etc/apt/sources.list looks like:

R32.4.3 is already a quite old release. For this release, there may not be an apt package nvidia-l4t-gstreamer. The nvidia accelerated gstreamer plugins should be installed by jetpack, so there should be nothing more to do. If gstreamer cannot find these, probably there is something wrong in your environment.
I’d suggest reflashing, and better use latest release.
