<div dir="ltr">Hi all, I try to encode a video test with OMX plugin for gstreamer on my raspberry pi and I have an error when I launch the gst-launch command. the gst-omx plugin was installed in my filesystem in /usr/lib/gstreamer-1.0. this is the gst-launch command with some traces : # export GST_DEBUG="omx:9" # gst-launch-1.0 videotestsrc is-live=1 ! omxh264enc ! udpsink host=10.33.229.91
