Comment (by BtbN):

 Ok, i'm done with bisecting and ended up with the following:

 There are only 'skip'ped commits left to test.
 The first bad commit could be any of:
 We cannot bisect more!

 2c541554076c was the last commit to test, and i couldn't compile it for
 some reason, as configure suddenly started not knowing most of the options
 i usualy pass to it(Using gentoo git ebuild for easy building+testing).
 After I finaly managed to configure it, it failed to compile with

 make: *** No rule to make target `tools/ffescape'.  Stop.

 I then manualy tested the b7fe35c9e50e17 commit, which configures and
 builds without problems, but also has the crash on mpeg2 decode.
 On each step, i manualy applyed the fix from b066d90211 if neccessary.

 H264 decodes fine, mpeg2 always crashes. Didn't test any other codecs.
 Program used to test libavcodec was a vlc git build.
