Hello,
I'm developing a HAL-based software running on STM32F778AI MCU. The software uses the hardware JPEG decoder in DMA mode.
It decodes 'classical' JPEG images that have 8-bit DQTs without an issue.
But if a JPEG's the precision of the quantization table is set to 1 and its luminance table defined with 16-bit values, then the JPEG decoder fails.
Is there a nice way to make F7's JPEG decoder work on JPEGs with 16-bit DQTs?
