gstreamer camera source IPU/GPU rotate method?

Hi everyone

 

Now I am trying to use the ov5640 camera with imx6qsabresd yocto project,

and I can use the following gstreamer command to show the preview from ov5640 to LCD.

 

>gst-launch-1.0 imxv4l2src device=/dev/video1 ! 'video/x-raw, capture-mode=1, format=(string)NV12, width=640, height=480, framerate=(fraction)30/1' ! imxv4l2sink

I want to rotate the preview,

and I have tried the ! videoflip method=clockwise !

but it seems like a software method and it is too slow(very low fps).

 

Is there any IPU/GPU or other HW method which can do the gstreamer rotate in high FPS?

 

thank you and best regard
