Disp Q&A

Q: How to scale and rotate the output image?

Use DIVP module to complete.

Code process: YUV422/NV12 → DIVP CHN0(scaling down/up) → DIVP CHN1(rotate) → DISP

The DIVP module supports time-sharing multiplexing. To achieve scaling + rotation, you need to create two channels, one for scaling, one for rotation, and the two channels are linked by sys bind interface. Reference divp_init.c .c).
