This should work:

  $ git remote add tpm-fdo git://people.freedesktop.org/~tpm/gst-plugins-good
    (I'm sure there's an http url too, but don't know it right now)

  $ git fetch tpm-fdo

  $ gitk tpm-fdo/matroskademux-scan-clusters-for-keyframe-2 &

You probably don't need the two first ones ("WIP: gdkpixbufsink-test") and the
last one ("matroskademux: implement keyframe search also without cluster prev
size") is also optional for you, but shouldn't do any harm.

I also forgot to mention that I ran into some issues when testing the initial
patch: when scrubbing/seeking towards the end of the file (beyond start of last
cluster? don't remember) I could easily trigger fatal seeking errors (though
I'm sure they could be fixed of course). I could only trigger it with a certain
sequence of seeks though.
