Hello @jsalg.1​ ,

Can you please provide more details ?

• Which version of TouchGFX are you using ?
• Did you try to delete you Middlewares/ST folder and regenerate code with TouchGFXDesigner ?

Thanks,

/Yoann

Thanks for your response, Yoann,

I am using TouchGFX Designer 4. 20.0 version. I have created application to play video clip (.avi), First I created screen and added video widget on top of that screen and generated code from touchGFX, later I opened the generated code folder and launched the STMCubeIDE by clicking on .cproject and clicked on the build project option from STMCUbe IDE.
