dan67397

I'm using dm365 and dvsdk4.00.I want to edit output video data in davinci_display_isr() (in davinci_display.c) when i run the decode demo.

but the addr is phys(0x8xxxxxxx)and nextFrm->baddr (0x4xxxxxxx)is for userland,I can not read in driver.How can i get the virtual address of video frame?

Have you considered editing the frame in application?

I need to do something for different applications.for some applications,

I have no src code .and i want to run other more applications easily.

so it is better to do this in driver.
