An error occurs, when a self-compiled version of gstreamer-0.10 is launched to use a gst-omx:

$ gst-launch-0.10 -v udpsrc port=9078 ! 'application/x-rtp,payload=96,encoding-name=H264' ! rtph264depay ! h264parse ! omxh264dec ! dfbvideosink

Surprisingly a similar error occurs, when I try a self-compiled gstreamer-1.0:

$ gst-launch-1.0 -v udpsrc port=9078 ! 'application/x-rtp,payload=96,encoding-name=H264' ! rtph264depay ! h264parse ! omxh264dec ! autovideosink

Suggests that the error may not be gst-omx related, but to be some kind of misconfiguration maybe ...

Maybe I need to compile gst-plugins-base with theora and gst-plugins-good with VP8 support

apt-get install libmpeg2-4-dev libtheora-dev libvpx-dev

No, that didn't solve it.

Turns out, the error messages are outputted from gstomx itself, while reading the config. The problem disappears, when removing all sections except H264 encode/decode from /etc/xdg/gstomx.conf.
