            Bug ID: 780509
           Summary: h264 encode: Disabling 8x8 transform tool causing
                    wrong selection of Profile
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gstreamer-vaapi

     GNOME version: ---

Disabling the dct8x8 in vaapih264enc causing issues with profile selection.

Sample pipeline: gst-launch-1.0  filesrc location= sample.nv12  ! videoparse
format=nv12 width=1280 height=720 framerate=30/1 !  vaapih264enc  dct8x8=0 ! 
"video/x-h264, profile=high" ! filesink location=sample.264

Expected outcome: encoded stream sample.264 in high profile

But the generated stream encoded as "main" profile ,even if we requested high
profile in capsfilter.
