Question

Can the hardware jpeg encoder of the STM32H743 encode YCbCr progressive scan from DCMI directly or some image preprocessing is needed before sending the frames to the encoder?

You need to convert YCbCr fromat into MCU format expected by the encoder.

Please refer AN4996 for details.

If DCMI frame rate is slow enough, you can use double buffering DMA technic and run software conversion process while receiving incoming YCbCcr data.
