Hi, I am using the demo applications for the resizer, the coefficients are setup by the header files for the demo... Euan C

When I run the demos all they show is a heavily distorted version of the previous frame (after running another demo e.g. encodedecode, or the blue boot screen if no demos were run before running the resize demo). >From the terminal window everything seems to be running smoothly as it shows >debug messages stating the time taken to resize each frame but it does not >output correctly to the display. On the TI website their FAQ suggests that the resizer may produce artifacts due to write overflows, I don't think I would class what I'm seeing as artifacts but I wanted to check this out anyway. However the register definitions they give to allow you to check for overflows don't seem to be correct (the FAQ lists them as RSZx_WBL_O and the app not lists them as VPSS_PCR.RSZx_WBL_O (where x is 1 to 4) but neither of these definitions work when compiling. Has anyone else had problems with the display output of the resizer demos or tried using these overflow registers? I am using DVEVM/DVSDK v.120.
