Comment (by m_doe):

 From my own investigation it has become clear that the OMX encoder in it's
 current form will only ever output H264 High 4.0 unless the encoder is
 explicitly told to use an alternative profile using
 OMX_VIDEO_PARAM_AVCTYPE.

 The encoder will also only support constant bitrate using a baseline
 profile, but not main or high. CBR can be achieved with the
 OMX_VIDEO_PARAM_BITRATETYPE. If this is not applied the encoder is
 essentially hard coded to run OMX_Video_ControlRateVariable, i.e. variable
 bit rate output.
