There is no support for FFMPEG HW accelerators in GStreamer and should not be
included in builds without pathces.
For OMX, you should look for gst-omx with RPi target build (because OMX from RPi
is not standard, well no OMX implementation is). You may want to start using
V4L2 drivers for RPi instead, with v4l2h264enc.
