Freeze Frame with the Video IP Suite

Has anyone determined how to do a Freeze Frame using the Video IP Suite? Can I use the GO bit in the Frame Buffer or is there another way to Freeze the video stream and keep a clean frame of video on...

Hello,

Yes, when repeating is allowed, setting the Go bit to zero on the run-time control of the writer thread should freeze the output stream.

However, you have to set the Go bit to zero before the frame buffer receives the end of packet of the frame you want to repeat. If you are trying to freeze the output in reaction to an event such as the video input cable being pulled out then it might already be too late for that.
