We are trying to use the IPU.IC for combining BG and FG.
We assume UYVY(BT.601) from BG and RGB565 from FG combined in the IC then output YUY2(BT.601).
The colorkey and global alpha value set to blend FG and BG but output looks corrupt.
We can see vertical stripe on screen and every odd(2nd) Y seemed always having wrong value.
For instance, in the data, we can see:
BG(UYVY): 80h 10h 80h 10h
FG(RGB565): 00h 00h 00h 00h
alpha is 0xff
result(YUY2): 10h 80h 00h 80h (our expectation is 0x10801080)
Do you have any ideas to fix this(2nd Y)?
