Capture config. BT878

[Racer]

Hi,


I've Accorp PCI capture card based on BT878 chip. The problem is that original capture settings is only 3 fixed image sizes for Pal: Full 768x576; 1/2 384x288 and 1/4 176x144. I'd like to know, how to change these defaults (in registers or dll's), because I need default size 720x576 and colorspace YUV, not 768x576, and RGB15 - it's for Ulead direct mpeg2 capture.

P.S. The card supports 720x576 an YUV colorspace - in VirtualDub I can choose "set custom format" and use these settings, but capture only in avi format

P.P.S. win98SE and vfw drivers, not wdm.

Any ideas how to change this?

capturing to uncompressed avi with huffyuv should give you best possible quality for further action (like de-interlacing/smoothing etc) and then converting into whatever suits you best.

o.k., thanks, I know that (better way is using picvideo mjpeg - quality like huffyuv, but don't need so much disk space), but that's no answer to my question about bt878 configuration
