Hi, Thank you Carl Eugen Hoyos:

I just have no idea what's the relationship between ffmpeg and libav? It
seems
libav is replacing ffmpeg? Which is newer? Are ffmpeg and libav 2 different
groups?

It's always problematic to build ffmpeg under Windows anyway. At the bottom
of
http://ffmpeg.zeranoe.com/builds/, the dependent 3rd party (external)
libraries
are afforded, but not all of those libraries are able to be built
successfully
under Windows. A typical example is bzip2:

$ make install
...
chmod: changing permissions of '/usr/local/bin/bzip2': Bad file number
make: *** [install] Error 1


In fact, I just want ffmpeg to be successfully built and be able to support
RTMPDump, x264, Xvid, etc.... However, there are always some problems...


Please do help...


Thank you very much.


Best Regards
Pei
