I needed a newer ffmpeg snapshot than the one in Portage so I grabbed a new nightly and updated the ebuild. It's had to change a bit because AMR now works through an external library. I also had to update one of the patches. Thought I might as well share my update to save someone some time. (-:
Created attachment 120197 [details] ffmpeg-0.4.9_p20070524.ebuild
Created attachment 120198 [details, diff] ffmpeg-0.4.9_p20070524-asmpic.patch
Seems it was bumped without looking at this. Ho hum.
