i.MX8QM - Unable to use imxvideoconvert_g2d

[AndreSilva]

Hi NXP Support,

I am trying to perform a colorspace conversion using hardware acceleration, with the imxvideoconvert_g2d, here is log:

GST_DEBUG=2 taskset 0x10 gst-launch-1.0 -v v4l2src device=/dev/video0 io-mode=dmabuf ! video/x-raw,width=1920,height=1080,framerate=30/1,format=UYVY ! imxvideoconvert_g2d ! v4l2h264enc ! h264parse ! matroskamux ! filesink location=gst.mkv

how about adding "output-io-mode=dmabuf-import" after v4l2h264enc ?
