Hi,

 

We have implemented the rotation of ipu by changing mxc_ipuv3_fb_rotate.c(file attached).
It give the successful rotation but when I start to stream the camera on display it gives the following error.

 

# gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! imxipuvi
deotransform ! imxipuvideosink
Setting pipeline to PAUSED ...
ERROR: v4l2 capture: unsupported ioctrl!
Pipeline is live and does not need PREROLL ...

New clock: GstSystemClock
imx-ipuv3 2400000.ipu: ERR[0xa8c8ac00-no:0x3e270]ipu task_id:1 busy!

imx-ipuv3 2400000.ipu: ERR: no-0x3e270,ipu_queue_task err:-125

 

Can you please help to sort out this issue?
