[FFmpeg-devel] [PATCH] Change behviour of empty AVFilterFormats lists

This makes an empty list mean 'all formats supported'. This will simplify some 
things for the format negotiation later on. Before the patch, returning an 
empty list in query_formats() would simply mean no format supported, which is 
non-sensical. This way a lot of unnecessary merging of 'all formats' lists is 
avoided.
