how can use "mppvideodec" with gstreamer
#1
Hello, 
        Actually i am using rockpro64(rk3399) board. I have flashed bionoc-ubuntu-64bit image. 
UI can see "mppvideodec" plugins when execute "gst-inspect-1.0 |grep mpp" command. 

But, when i tried to use "mmpvideodec" in gstreamer,k i got some errors as below: 

Setting pipeline to PAUSED ... 
mpi: mpp version: Without VCS, under bleeding 
Pipeline is live and does not need PREROLL ... 
Got context from element 'autovideosink0': gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayX11\)\ gldisplayx11-0";

Setting pipeline to PAUSED ...

I have tried pipeline as below: 
1. gst-launch-1.0 v4l2src device=/dev/video0 ! mppvideodec ! autovideosink 
2. gst-launch-1.0 -v rtspsrc location=rtsp://admin:jenex#2018@192.168.1.108:554 latency=10 ! rtph264depay ! h264parse ! mppvideodec ! videoconvert ! autovideosink sync=false 

Moreover, what is the meaning of "none" in below output:
