Hi

I want to display 4 channel video to one monitor.

I displaied 4 channel video croped. but I'd like to display full size image not croped using resize.

Could you guide how to resize yuv image? camera image size is 1280x944, 4ch / display resolution is 1920x1080.

Thank you.

    Hi Lee,

    You could use Mosaic Node to display multiple video on a single frame. Please check multi-camera example, it displays 4 camera input in 2x2 format in single frame.. You could even change it to display in 4x1 format. 

    But please note that it cannot do upscaling, so it cannot upscale from 1280 width to 1920 width.. If you want to display in 4x1 format, then resolution for each output would be 1280x270 from 1280x944.. 

    Regards,
