Can we use IPU for convertiong NV12 to NV21 in libcamera2

Hi All

NV12 to Nv21 conversion is taking lot of cpu for 720P stream. Can we use ipu for the conversion to increase the performance ?

Hi GAUTAM,

MX6 IPU support NV12 format, however it does not support format conversion between NV12 to NV21.  However the only difference I found is to switch U and V byte between NV12 and NV21 according to reference. (http://www.fourcc.org/yuv.php). do not see any specific reason to take a lot of CPU consumption, in this case you should debug it to find the root cause.

Hope this helps
