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:
2c541554076cc8a72e7145d4da30389ca763f32f
b7fe35c9e50e1701274364adf7280bf4a02b092b
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.
