[RZ/G1E] Display image is wrong with VSPM filtering

Hi all,

I am trying a scaling, displaying, and file saving on RZ/G1E (BSP for starter kit + multimedia package).
But, display image is wrong. I attached the image.

This is the flow of concrete processing.

  H.264 dec -> scaling & NV12 format convert with VSPM (DATA-A)
    DATA-A -> format convert with VSPM -> display(wayland)
    DATA-A -> NV12 file saving

[Command]
# gst-launch-1.0 filesrc location=input.mp4 ! qtdemux ! omxh264dec ! vspmfilter outbuf-alloc=true ! video/x-raw,format=NV12,width=800,height=480 ! tee tee0. ! vspmfilter outbuf-alloc=false ! video/x-raw,format=BGRA ! waylandsink sync=false async=false tee0. ! filesink location=output.dat sync=false async=false

BTW, if set I420 format, display image is good.

# gst-launch-1.0 filesrc location=input.mp4 ! qtdemux ! omxh264dec ! vspmfilter outbuf-alloc=true ! video/x-raw,format=I420,width=800,height=480 ! tee tee0. ! vspmfilter outbuf-alloc=false ! video/x-raw,format=BGRA ! waylandsink sync=false async=false tee0. ! filesink location=output.dat sync=false async=false

Do you know how to resolve?

Best Regards,
Kenji
