I am not sure I understand what this is supposed to do.
If you want to run a filter with an input conversion, in principles, you can
simply make it override its input format and return VLC_SUCCESS. You probably
also want the output format copied from the output format.
So I don´t see why you need to change either the core or the chain converter.
And not only I don´t see the need, but I very much suspect that it breaks the
use case whereby a filter legitimately refuses to start by returning an error.
E.g. deinterlacer on RGB input, VDPAU filters on CPU chroma...
