[x264-devel] Not using all pictures as reference

Hi!

Is it possible to configure x264 to not use all pictures as reference
pircute? Like only using every other or every fourth picture as a
reference picture?

My application is streaming an encoded file over a network with (at
encode time) unknown bandwidth. Therefore it would be useful to be able
to change the stream's required bandwidth by dropping pictures that
does not affect the state of the decoder. What I would like to achieve
is sort of a "poor mans" bitrate-scalability.

Thanks for any help
/Fredrik
