STM32F769 jpeg header decoder Problem

hi

I am practicing jpeg hardware decoding with stm32f769 disco board. During practice, some images were displayed normally, but some images could not be displayed at all.

 

I tested with this :
STM32Cube_FW_F7_V1.17.0\Projects\STM32F769I-Discovery\Examples\JPEG\JPEG_DecodingUsingFs_DMA
 
I haven't modified the example.

As a result of comparing headers that display images normally and headers that do not, it seems to be related to the number of marker ID SOS (Start of scan: 0xffda).

The images displayed normally had only one SOS, but there were several images that could not be displayed at all.

How should I handle images that are not displayed due to these headers.

Can you please support me with a solution for this?
