- Now histogram update if some windows is playing but not the current window - If the current window is a module window it will check if the source window is playing - The white fill of the window is only drawn after 500ms. Trying to reduce the continuous refreshing even on simple modules
Calyp
Enhanced YUV video player based on Qt focusing on image/video analysis
