nv_omx_h264enc does not connect with rtph264pay

[ondrahnilicka]

Hello,

I would like to encode video on my Tegra T30 Apalis board with L4T (Angstrom
Linux) to H.264 and send it over UDP. When I run the statement: 
gst-launch -v videotestsrc ! ffmpegcolorspace ! 'video/x-raw-yuv' !
nv_omx_h264enc ! rtph264pay ! fakesink silent=0   (or with udpsink)

i got this error: "Element doesn't implement handling of this stream."
The whole error description is below.
I tried many similar statements and compile the app in C with the same
result. The problem is really between the nv_omx_h264enc and the rtph264pay
plugins. I tried the x264enc encoder instead of the nv_omx_h264enc and it
works. In rtph264pay sources i see that "payload" hasn't adjusted a
clock-rate, but i don't know where to fix it. Maybe it is a plugin version
problem.

Versions:
gst-launch-0.10 version 0.10.36
gst-plugins-good - 0.10.31-r13.7
nv_omx_h264enc version 0.10.1

Does anybody have an idea?

Thank you.
