However because most TV channels now air with 16:9 content inside 4:3 images, I would like to crop out the top and bottom black bars before encoding via the hardware MPEG2 encoder. I tried using the ctl_crop_top and ctl_crop_height in /sysfs as well as the --set-crop option of v4l2-ctrl but only received error messages indicating a value out of range. The card has a cx25843 which should support cropping. Does anyone know how to get this feature to work ? Thanks in advance for the help, Joseph
