[Ffmpeg-devel] Strange nb_streams value

Hi again,
I got another heavy problem. After opening an AVI file with 
av_open_input_file(), the given AVFormatContext is invalid. 
av_open_input_file returned 0 so I think everything works 
fine inside the function. I looked into av_open_input_file 
and the AVFormatContext it generates is valid until the end 
of the function. Also the pointer returned by it is valid. 
But after the function returns it is invalid again, although 
it points to the correct location where the generated 
FormatContext was before the function returned. Just for 
your Information: I compile ffmpeg using MinGW (tried both 
'./configure --enable-shared --disable-static --disable-mmx' 
and './configure --enable-shared --disable-static 
--enable-memalignhack'). The Program that uses avformat and 
avcodec is compiled and linked by Microsoft Visual C++ 6.0. 
Please help this time... my other questions all stayed 
unanswered for some reason.
