no clue if this will work, but looks worth a shot:

https://edge.launchpad.net/~freshmedia/+archive/ppa

I found that by clicking around in:

https://edge.launchpad.net/ubuntu/+ppas?name_filter=ffmpeg

It worked!

here is the scripts I use for updating stuff:

http://dev.personnelware.com/carl/a/updebs/uplibdv.sh

it makes a libdv4 dir, installed the build deps, grabs the souce, then
exits so you can cd in there and make the change (which isn't on the
line, search for
return dv_is_normal_speed(decoder); /* don't do audio if speed is not 1 */

replace it with
return(TRUE);

once the change is made, cut/paste the rest of the commands from the
script (I should really have a .diff and patch command.. but...)

debchange --nmu $0
# build the .deb
# dpkg-buildpackage -uc -b
DEB_BUILD_OPTIONS="nostrip" dpkg-buildpackage -uc -b
# install the deb.
# using this command, on your own :)
set +x
cd ..
echo cd $PACKAGE/
for i in *.deb; do
  echo sudo dpkg -i $i
done


There is one to grab ffmpeg trunk too - it shuffles around the debian
dir, and might run all the way though without any intervention:

12 seems high. but I wouldn't worry about that 'now'
