The attached patch should fix this, it was missing a condition for skipping 
insertion of the convert filter.  It now skips conversion if inpixfmt == 
FMT_NONE for empty filter chains.

I also replaced all (I think) appropriate instances of -1 with the enum value 
FMT_NONE, should make it clearer what's going on, and keep things from 
breaking horribly if the value should change in the future.
