regarding DM6437 Resizer

rect
Prodigy 170 points

HI,

I am using dm6437 evm. I tried video_preview application in dvsdk and it worked fine. My application requires frame with widthxheight 1280x800. in the video_preview example frame widthxheight are set to 720x480 for both front end and back end. i dont have problem in displaying 720x480 in the output but i need a 1280x800 input. I just checked through resizer and it does upscaling only in 2x i.e if input is 320x240 its upscaled to 640x480. is there a way to upscale 720x480 to 1280x800?

    Hi rect

    The resizer can scale from 1/4x to 4x, although there are some limitations. You should read SPRU977D (particularly section 5.6.6) and SPRAAI7B for more information.

    If you are unable to get the resized ratio you want, you could consider passing your image through the resizer twice. This will give you a wider range of options.

    I didn't have a Linux machine around on which to run the supplied calccoeff utility (SPRAAI7B 4.3) I ended up setting up a virtual Ubuntu machine using VirtualBox. This gives you an easy (and free!) way to run the utility. I've not found a Windows version of calccoeff, but if it's available I'd very much like to hear about it!

    All the best
