question about subFrameMode

Hi,

I have a question about subFrameMode.

I used the rdk4.0 on DM816x, and I want to realize the image rotation by used tiler, my image resolution is 2952*1936.

I used the link as follow:

capture ->dei0 ->dei1->framesout->...

I enable tiler on dei0, and translate the tiler address to 90-degree address on the output of dei0, and the dei worked on bypass mode.

However, the dei only  support the max resolution of image is 1920*1080.

Could I enable the dei subFrameMode to realize the 2592*1936 non-tiler memory to 2592*1936 tilered memory by the deiLink.

Regards,

Tianxing

    No subframe mode cannot be used. Subframe mode is to reduce processing latency by providing callbacks after subframe processing is compelte. It doesn't enable processing mega pixel resolution. Only link that supports mega pixel resolution scaling is mpScalerLink.
