[Ffmpeg-devel] ffmpeg crashes on windows

I've happily used ffmpeg in my code for quite some time. Currently I
tried encoding a video and it just didn't worked anymore. I have
updated the CVS since it last worked so something happened there.
Naturally I got the very latest version from the CVS and rebuilt but
it still doesn't work! I thought it was my own fault somehow but it
seems other have been suffering from the same problems on the list.
Here's a list of what does not work:
ffmpeg.exe crashes (access violation, no output)
output_example.exe works but says "could not open codec" for any
format I've tried
The same thing happens to my own code; avcodec_open does not work
anymore! It returns something <0 for ANY format I've tried. FFmpeg.exe
might never have worked on my computer - never tried it before - but
output_example worked alright before and so did my own code.
I compile using MINGW32 with visual studio .2003 for creating the
.DLL-files. Lotsa warnings during compile (as always) but no errors.
Hope I'm not wasting your time!
