Part Number:AM5728
Tool/software: Linux
Hello,
I am using AM5728 PSDK 04.00.00.04.
We specify the dual camera, sample source (modetest.c) and currently WB 1920 x 1080p HDMI to the LCD.
ioctl (VIDIOC_STREAMON, VIDIOC_STREAMOFF, VIDIOC_DQBUF, VIDIOC_QBUF ...)
1080p has no problem.
but, if 1080p HDMI is changed to 1080i, WB, a lot of error messages occurred
Although it is displayed on the LCD on the WB screen, it is not a general screen.
An error message is attached.

==============================================
This problem also occurred in PSDK 03.01.00.06 version.
At this time, we solved the problem by modifying wbcap_handle_vsync (struct wbcap_dev * dev) of omap_wb_cap.
However, the same solution is not applied in PSDK 04.00.00.04 version currently in use.
Our customers want the 1080i.
please, I want you to help me.
Provide cases where more information is needed.
Thank you!
