 Using audio upmixer, avcodec_open gives this error message:

 "Specified sample_fmt is not supported."

 Since there is no error code returned, execution proceeds until there is
 then a floating point exception in AudioOutputBase::AddData when
 calculating maxlength because encoder->FrameSize() is zero.

 The attached patch seems to fix it.  Also, there is now a floating-point
 AC3 encoder available so the patch includes a change to select the encoder
 by name.
