Hi together,
I want to use the Video Widget with the STM32U599 and TouchGFX version 4.25.0, but I can't activate video mode in STM32CubeMX.
Are there any new details about this problem?
Or is video usage not supported with the STM32U599?

Hello @IHaas.1.

STM32U599 does not have the JPEG codec peripheral. To achieve hardware-decoded video on U5, you need to use STM32U5F7/G7 or STM32U5F9/G9.

However, it should be possible to achieve software-decoded video, although I have not tested it on STM32U599 myself. Unfortunately, STM32CubeMX does not provide the LibJPEG middleware for STM32U599. However, you should be able to copy it from another MCU where it it included, such as one of the STM32H7. Use version control to track changes when enabling LibJPEG in STM32CubeMX and activating software video decoding in the X-CUBE-TOUCHGFX middleware.
By replicating these modifications, you should be able to achieve software-decoded video on STM32U599.

Best regards,
Johan
