He Junyan 248baef400 MSDK: Import VA surface as encoder's input.
We make all MSDK encoders declare "memory:VAMemory" feature. Then
the pipeline such as:
  gst-launch-1.0 -vf filesrc location=xxx.h264 ! h264parse ! \
       vah264dec ! msdkh265enc ! fakesink
will choose VA memory caps between the VA decoder and MSDK encoder.
