how to make decodebin select va-api decoder.

[cfd new]

Hi, Chris,
   thanks for your reply. I tried it
   GST_PLUGIN_FEATURE_RANK=vah264dec:259 gst-launch-1.0 -v filesrc location=/home/simulator/Downloads/test.mkv ! decodebin ! autovideosink

the output still shows that avdec_h264 is applied.

  hello 
  by API, you can connect to the "autoplug-select" signal
  else you could set "GST_PLUGIN_FEATURE_RANK" (seehttps://gstreamer.freedesktop.org/documentation/gstreamer/running.html?gi-language=c)

has output to show av decoder is applied. How to make decodebin select va-api decoder. 
vaapi decoder is not installed. Instead, va-api decoder is installed.
