playbin can't detect vaapi decoder correctly when playing a video stream.

I'm trying to turn on streaming video with H.264 codec manually. I have noticed spice-gtk will use playbin to decode the video stream with recent gstreamer.  However,  playbin tends to use software decoder (avdec_h264) on my box (latest Archlinux running on an Intel i5-6500 PC with gstreamer-vaapi). When I remove gstreamer-libav, gstreamer complains like this and refuse to setup pipeline:

However, after install gstreamer-libav, the log shows playbin is using avdec_h264. Also, I can confirm playbin is using vaapih264dec when I manually change the encoder of spice-server from x264 to vaapih264enc.
