That will take roughly 7,5 hours (give or take) in a worst case scenario.
That's why I want to automate with git bisec run. I played around with "git
log" a found a commit that (what I think) seems close to 0.10 that will
produce 13 iterations:
$ git bisect good 33c21378a846d880110324f3e139a693a9bb30ca
Bisecting: 6686 revisions left to test after this (roughly 13 steps)
[15a0fb58a3294876c23989915a4a6202411be1b0] Merge remote-tracking branch
But it seems you are using an earlier commit. Which commit did you use for
"git bisect good"?

Ok, I'll test that too!

Ok, lets do it! :)

Well, yes - we're aware about the new api and that 1.2 will the be the last
version with the old api. But since a change to the new api will take some
time to implement, we want to use the version 1.2 that solves a bunch of
other more or less serious problems that we currently struggle with in
version 0.10.2. We are talking show stoppers that is for instance
preventing users to watch certain content types, hangs or causes stuttering
video playback. And we can't be sure this problem won't occur with the new
api, can we?
Xbmc does currently work with ffmpeg n1.2 on all platforms except IOS thus
it's worth the effort to fix this particular problem.
