Dear Community

i have a question about Horizontal inversion(horizontal flip)

i know imx6's ipu has below IP block

Image converter , Image rotator

IC and IRT has a horizontal inversion

my first question is how can i use that function of IC or IRT ?

what is best choice of IC or IRT ?

i already 120 bit set to 1 , but movie clip is not changed

i did some test with mxc_vpu_test.out program

mxc_vpu_test.out has a option "-m" about mirror

i have confirmed horizontal flip video with "-m 2" option

but i have a question VPU has a function about horizontal flip ?

What is different IPU flip and VPU MIRROR ? it is my second question

Hi Allen

vpu and ipu are different blocks, vpu is processing

only video. For vpu mirror capability one can look at attached

VPU Linux Programming Manual sect.sect.3.2.1.12 MirrorDirection.

As for ipu one can look at examples on

ipu-examples release notes - v0.1 | NXP Community

i.MX6 IPU and rotating a frame buffer | NXP Community

seems it is possible to reuse rotate example for conversion it to mirror

Best regards
igor
