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

libvcos.so is found in /usr/lib folder and I think the library is loaded
properly.
I use gstreamer 1.0.8 and the last git gst-omx.
thanks for your help.
