We need a complere bugreport you are missing approximately 99%
which exact revissiom broke it
which file? url of where its available
how to reproduce? exact command lines, exact output from whatever tool you use
to identify cpu useage with old and new revissions

also this belongs to our issue tracker
i normally do not mind complete, short and clean bugreports on ffmpeg-dev 
but this one doesnt look like one.
