Hello, I want to preview my video on HDMI LCD, my cmos sensor is 8 bit grayscale, 752x480. and I tested it with mxc_v4l2_overlay.c from imx_test package.
I find the image show in LCD in not the same as the sensor output, i.e. smaller , copied to 16 same images, green background! (see the attachment)
I want to know if grayscale image direct preview is supported by imx6q? if yes, how should I modified the driver(I have modified the driver for capture grayscale sensor image, but not for preview)?
or do I have to first capture it to mem,then output to LCD (mxc_v4l2_output.c)?
thanks a lot !
