Hi, Well, I thought the 'J' was a mistake :D But I don't see any reason it wouldn't work.

However, just to be sure: Are you sure this converts yuvJ420p (not YUV420P) to RGB24? I have been using those same functions, but it always give me the green screen with noise. I will try again anyway.

However, I have found out that the format of the frame is in YUVJ420P but I need to display in RGB24. When using sws_getContext and swscale, all I get is a green screen filled with noise. Does anybody know how I can make this conversion work?
