[XviD-devel] Variable frame rate -plugin_single.c

[Makira]

I sent this on 16 sep., but I think it didn't get to the list since I hadn't
subscribe. Sorry if this is a double post.

I'm using xvid in OpenShiiva (http://openshiiva.sf.net).

Just updated to xvid dev-api-4 cvs of today (a few hours ago).

The only file I changed is the plugin_single.c file. If you could integrate
the patch for vfr, I wouldn't have to keep a local copy... I think it is
safe, it shouldn't affect normal usage afaik.
