we are porting RTOS system for imx6 platform and have an issue for IPU function.
Is that possible to change the parameter (such as width/height/u offset etc.) for CPMEM channel buffer without closing the channel?
We need to do Seamless switch for different resolution movies，it is more simple if the bg channel can output different resolution image (like from 720p to 1080p) without close the bg channel.
Or do you have any other proposal for this kind of function?
