Darn, and here I was hoping there was a policy change in favor of
vector intrinsics ;-)
Would a patch replacing some of my mmx.h-based work with vector
intrinsics be accepted if the mmx.h macro code were retained and
selected via an #ifdef for older compilers?

There are two patches here. The first, cleanup-verbose-nvr-v1.patch,

The second, cleanup-exit-nvr-v1.patch, replaces a number of exits with a
errored boolean and some tests of that variable.

I don't know if it's related or not, but there is some timecode wierdness in

A while back there was some discussion about the audio time code sync
packets being wrong for some reason and that caused playback problems.
