TX2 r28.1 omxh265enc Warnings

I get three warnings when using omxh265enc in the below pipeline. Can anyone help me clear them up? What is the consequence of these warnings? As-is the video streams successfully.

  1. WARN omx gstomx.c:2836:plugin_init: Failed to load configuration file: Valid key file could not be found in search dirs
  2. WARN omxh265enc gstomxh265enc.c:146:gst_omx_h265_enc_set_format: Setting profile/level not supported by component
  3. WARN omxvideoenc gstomxvideoenc.c:1804:gst_omx_video_enc_set_format: Error setting temporal_tradeoff 0 : Vendor specific error (0x00000001)

Hi,
These warning prints should be harmless. 2 and 3 are false alarms.
