Thanks!

Hi Marco,

The maximum limit for second resizer output is 1088 pixels per line. This is mentioned int he Programmers Guide for VPFE on DM365.

Dear Anshuman,

then the current limit of 640x480 is just a linux driver issue? Can it be avoided by allocating a bigger buffer in the driver or is it strictly enforced elsewhere?

Thanks!

Marco,

Yes, the driver is limiting the size of the buffer. The value of 640x480 is not used anywhere else but in buffer allocation. There is no check for max width for resizer B for 640 pixels.

So if you just change your davnci-vpfe.c file in the kernel for allocating bigger buffer to meet your requirement, it should be good enough.

Let me know if it helps.

Anshuman
