Hi,
as I described in another post, some strange artifacts appear on my screen. In my application a video stream comming from CCDC is stored to SDRAM, resized by IPIPE and displayed through the VPBE on a TFT monitor. The artifacts are best described as ripped appart frames.
I am working on this problem now for a while. There had been many more artifacts in my frames, which I detected by reading the column right after the frame. The column has to consist of black pixel only, otherwise IPIPE wrote pixel data into a wrong area. This detection reduced the flickering from one in evry 5 seconds down to one every 5 to 10 minutes.
But still, every 5 to 10 minutes one ripped frame is displayed, which I am not able to detect. My guess is that the VPBE is responsible for the last ripping artifacts.
I realy can use some feedback on this...
