It's not a permissions problem:

I compiled ffmpeg as jsd and installed with sudo, although I don't know why that
would make a difference.  I've been using unix for almost 20 years now and
that's the first time I've ever heard someone say that.

BTW, same result with apr 25 ffmpeg on mac os and yesterday's ffmpeg on centos
linux... so it's not likely to be OS-related.
