yes,I have test the ipipeif rsz and the ccdc culling pattern,I think these two methon is different in their implement: the ipipeif rsz only dicimate the pixels that is larger than 1280 pixels,so it is not the real scale,which means you can only get the left block of the image; and the culling pattern decimate the pixels in a different way,you can specifies the decimation parameter in a 8x8 windows,so you can get a whole look of the image Am I right?

I have done resize of 1920 pixels to 1280 pixels. You need to set the rsz parameter to input width * 16 / output width. Also set decm in ipipeif cfg register to 1 to enable decimation at the ipipeif. If you are using the ipipe driver provided with MV LSP, this can be achieved by setting these parameters in the ipipeif structure for IPIPE_SET_PARAM ioctl. structure name ipipeif parameters :- decimation = 1; rsz = <value calculated as above> From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of pavelhan Sent: Thursday, October 09, 2008 5:24 AM To: davinci-linux-open-source Subject: Is there anyone use the ipipeif resizer on the dm355? Hello All! From the dm355 VPFE datasheet,the resizer block on the ipipeif(not ipipe) has the ability to resize the input image to its 1x to 1/7x resolution.But in my application, I find that if I use it to resize a 1920x1080 image to its 1/2 resolution and then perform the ipipe processing,I only can get the left block of the image displayed on the TV.In my viewpoint, I hope I can get a full image with a smaller resolution disaplayed on my TV,not just the left block.Is it possible to use the ipipeif resizer to achieve this goal? Thank you! Any help will be appreciated! 2008-10-09 Pavel Han Oplinx Co.,Ltd Address:Hanggang Fuchun Business Mansion 2116# Futian, Shenzhen 518041,PRC Tel: (086)0755-88359865 Website:www.oplinx.com.cn E-mail: [EMAIL PROTECTED] __________ Information from ESET Smart Security, version of virus signature database 3608 (20081113) __________ The message was checked by ESET Smart Security. http://www.eset.com
