Issue behavior

Describe the current behavior

sample_decode  h264 -i  <1920x1080 ideo> -o <1920x1080 YUV>
sample_encode vp9  -hw -w 1920 -h 1080 -nv12 -f 30 -i <1920x1080 YUV> -o out.ivf

Playback the ivf video with VLC is slow.

Debug information

• What's libva/libva-utils/gmmlib/media-driver/Media SDK version?
• Could you confirm whether GPU hardware exist or not by ls /dev/dri?
• Could you attach dmesg log if it's GPU hang by dmesg >dmesg.log 2>&1?
• Could you provide vainfo log if possible by vainfo -a >vainfo.log 2>&1?
• Could you provide strace log if possible by strace YOUR_CMD >strace.log 2>&1?
• Could you provide libva trace log if possible? Run cmd export LIBVA_TRACE=/tmp/libva_trace.log first then execute the case.
• Media SDK tracer output (https://github.com/Intel-Media-SDK/MediaSDK/blob/master/tools/tracer/README.md)?
