Interesting, some things to try tonight. The patch to ao_oss.c is to
set the sample rate after pausing/resuming, which was breaking ac3
passthrough on my sound card. I'll play around with the audio options
some....

On the advice of someone on the freebsd mailing lists, I reduced my
patches to just those that are required to compile, and reduced my
configure arguments closer to the default. It didn't make a
difference, audio is still correct, and video plays too fast.

I am now configuring with:
--extra-cflags="-DBROKEN_RELOCATIONS -I/usr/local/include/freetype"
--enable-freetype --enable-vdpau

and the diff is reduced to:
