Naturally, if I could just mark areas to show in the input video, and have each sink grab its own area of interest, then I wouldn't need to have 16 streams which get individually cropped and border-added. </BLOCKQUOTE> I've implemented a 2x2 video-wall using 5 RPi using only videocrop with a single stream (obviously that technique mean each RPI receive a quarter HD stream). I had a copy obviously because I didn't have time to improve videocrop to offload cropping to the eglglesink. The videocrop API (hence the CropMeta) where completly sufficient. Can you explain why in your wall design you need to add black borders ? cheers, Nicolas </BODY> </HTML>
