New frame before end of frame error (IPU)

How should "New frame before end of frame error" (IPU_INT_STAT_5) be handled in the IPU? I have not been able to find any documentation on how this error condition should be handled. I would appreciate if someone could point me to the relevant documentation.


Whenever this error occurs the video being overlaid on the display is vertically offset from the top, wraps around and never recovers its correct vertical offset. I am reproducing this issue by switching between 2 analog video inputs.


My current plan is to handle this error by detecting the "New frame before end of frame error" and then restarting the video overlay as this has proven to be the only way to correct this problem.


I would appreciate any feedback on whether this is the right way to handle this issue.


Thank you.
