One thing to try: remove the following three lines from ffmpegwriter.h:
#if defined _MSC_VER
#define EMULATE_INTTYPES
#endif

If that does not help....

Using google I found this bug report:

You could try to locally apply the patch at the end of the first post to
common.h from libavutil in the contrib/ffmpeg directory.

Alternatively, you could update contrib/ffmpeg to a more recent snapshot
of ffmpeg (using svn update). Maybe they have already fixed the problem.
However, it is possible that gephex won't compile against the most
recent version of ffmpeg.

As a last alternative, you can disable gephex's ffmpeg support (see
configure --help). In that case, gephex will still work but will not
be able to load videos.

In any case, I would be interested to hear how you solved your problem.

Btw, somebody experienced a similar problem more than a year ago [1].


Regards,

Georg
