<div dir="ltr">Thank you everyone for the suggestions!<div><br></div><div>@David Ing your suggestion was definitely correct. As per your advice I searched around for a list of required libraries for the gstreamer source build and came across this article: <a href="https://medium.com/@nareshkumarganesan/nvidia-hardware-accelerated-video-encoding-decoding-nvcodec-gstreamer-4b8eab662bf1">https://medium.com/@nareshkumarganesan/nvidia-hardware-accelerated-video-encoding-decoding-nvcodec-gstreamer-4b8eab662bf1</a>. It provided me a full list of suggested libraries to install to support gstreamer. After installation, and some tweaking, the tutorial code examples now seem to run fine. Thank you for your help!<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 22, 2021 at 10:55 AM David Ing <<a href="mailto:ding@panopto.com">ding@panopto.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">The build (gst-build) requires many packages to be installed in order to support certain features.
