Critical Issue
When you turn on frame locking in the Clocked Video
Output it attempts to align its start of frame (output by
the vid_sof signal) to the incoming start of frame
signal (the sof signal). When it achieves this aligment,
the IP core frame locks the output video (the start of frames are
aligned) to the input video.
This issue affects systems enabling the frame locking functionality in the Clocked Video Output.
The output video frame lock is out by one cycle.
To work around this issue, move the Clocked Video Output start
of frame one cycle earlier. For example, if the start of frame required
for Mode 1 is at sample 10, write 9 into bits 2 to
15 of the Mode1 SOF Sample register.
This issue will be fixed in a future version of the Video and Image Processing Suite.
