After a look at your code, it seems that to solve my problem, i need to add the following in paramProc :
| CODE |
if (g_VFVAPIVersion>=12)
{
const VDXPixmapLayout& pxsrc = *fa->src.mpPixmapLayout;
VDXPixmapLayout& pxdst = *fa->dst.mpPixmapLayout;
pxdst = pxsrc;
}
|
if i declare V16, not needed if i declared V15. |

Sorry for the delay in replying (I'm kind of on a weekend cycle now).
Your fixes are both correct. V16 no longer allows you to access mpPixmap in startProc() because that was requiring the runtime to allocate a buffer just to start the filter, which wasted memory. mpPixmapLayout has been valid there since it was introduced and you should use that in startProc for all API versions that have it.
I changed the default behavior of paramProc() for similar reasons, since the default was causing unnecessary constraints on buffer allocation. You don't actually need to copy the entire struct, just the pitch.
