Hi, I purchased a NanoPi NEO AIR recently, and I've been trying to get gstreamer1.0 to run and encode h264. I've installed the gst-plugin-cedar but get the following logs: GST_PLUGIN_PATH=/usr/local/lib/gstreamer-1.0/ gst-launch-1.0 -ve videotestsrc ! cedar_h264enc ! h264parse ! matroskamux ! filesink location="cedar.mkv" Setting pipeline to PAUSED ...
