Usage of yuvcorrect_tune is a bit tricky, and usage given by yuvcorrect_tune -h is not sufficiently explicit, it seems. In fact, first of all, fifo must be a fifo, that is, you create it using command "mkfifo fifo" Then, you lanch "cat fifo | yuvplay" in a first shell, and then you launch "yuvcorrect_tune -I frame -M HALF_LEFT > fifo" in a second shell You should see your image appears your the left part adjustable using various keystrokes. I can see also I forget to mention that pressing the ESCAPE key will allow you to change of correction type. Hope it works for you too, as it works for me.
