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?
