gstreamer camera source IPU/GPU rotate method?

[stevesu]

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

Hi Steve

one can look at attached Linux Guide from Linux 3.14.28
