libffmpeg.so from new sources

[warchief]

Hi there,
I cross-compiled libffmpeg.so succesfully like you described here.
But then I saw that the sources you provided are pretty old: opus 1.0.2 and especially ffmpeg 1.0 is out of date.
Just replacing old versus new sources folders on my own fail to compile: opus won't be found with newer sources.
So would you provide us with newer sources anytime soon or would you tell me what to edit to get a compilation done?
Thx in advance.
