In my project, SD card was used to store the video, JPEG peripherals +DMA2D were used to convert the video format and finally displayed on the LCD screen, but only the first 4 frames could be converted each time, and then HAL_JPEG_DecodeCpltCallback could not be entered.While entering HAL_JPEG_DataReadyCallback all the time, the output address increases consistently and eventually exceeds the SDRAM size area, causing DMA access errors.
The relevant documents refer to:STM32Cube_FW_H7_V1.8.0\Projects\STM32H743I-EVAL\Examples\JPEG\JPEG_DecodingUsingFs_DMA
Here's my project.
Thank you very much for your help here!
