Hello ,

I have a problem when i use IPU to resize a grayscale picture。And my english is not well。I need your help。

./mxc_ipu -c 1 -i 2496,3520,IPU0,0,0,0,0,0,0 -O 4096,7024,IPU0,0,0,0,0,0 -f temp-2a.raw temp.raw

Here is a serial port debug information：

mxc_ipu mxc_ipu: Warn: no:0x0,calc_stripes ret:1 //

====== ipu task ======

input:

foramt: 0x59455247

width: 2496

height: 3520

crop.w = 2496

crop.h = 3520

crop.pos.x = 0

crop.pos.y = 0

output:

foramt: 0x59455247

width: 4096

height: 7024

roate: 0

crop.w = 2048

crop.h = 2048

crop.pos.x = 0

crop.pos.y = 0

Hi yu

The existing stripe algorithm used for the image resizing is limited to ~2000 x ~2000 pixels –> for the input frame. the current max resolution is 5616x3744. Regarding the resize limitation of multiples of 16 , it may be possible for YUV4:4:4
