Hi,
I'm using frame buffer to freeze, that is clearing the GO bit of the writer of frame buffer, and it turned out clean, and I released the freeze(setting the GO bit), the screen returned to normal without flickering. The dataflow is like this, CVI->FB->CVO. But when I used the dataflow which I have uploaded as the attachment, the freeze turned out to be fine, but when I released the frame buffer(setting GO bit), I noticed the screen just flickered a little and returned to normal. So can someone give me a hint on this ? Is it not appropriate to freeze frame with frame buffer? Thanks a lot!Link Copied

Hi,
Make sure you tick the check box "discard invalid frames/fields" in the vfb. Otherwise, the incomplete frame stuck between the CVI and the VFB during the freeze will be propagated when you restart the frame buffer and the output will glitch.- Mark as New

Yes, I have ticked the check box "discard invalid frames/fileds" in the vfb. But it still flickered. I am out right now, I will upload some snaps of my configuration later. Thx again for help.
