Unfortunately I'm not using the command line. :-(
I am linking to the DLLs produced by mingw/gcc from within Visual
Studio.  And I know it's not a VS problem (so don't bash, please?),
because this stuff has worked before.  I am programmatically generating
frames of noise and throwing them at the encoder.  I set only certain
members of AVCodecContext (as mentioned in the first email), and leave
the rest to default.
