  avcodec/vc1 : fix mb_height for field pictures
  Fixes ticket2531
  Tables are always allocated now with sufficient space for either progressive
  
  or interlaced content. The alternative would be to detect a change
  
  and reallocate.

  In short the errors are :

  I have tried with and without the :1935 port number, with ffmpeg_x64.exe but no difference. Is the stream key the invalid argument or something else ?

  Revert "Merge commit ’61c31e4ee7ea79a9e74c0476b81244febf17e6d7’" (configure : Properly set zlib dependencies for all components)
  The reverted commit introduced undefined behavior.
  
  undefined in the sense that the evaluation order of the dependencies affects the results
  Fixes Ticket2920
  This reverts commit c32db6adab9942781cc5a23f62abb839a5595a83, reversing
  
  changes made to 05f1b4e2ecc4683467669a190e3a53df413de805.
  Alternative solutions would be to change the dependency solver to handle non trivial
  
  dependencies or to enable zlib by default before the dependency solver, this would
  
  leave a zlib dependency in the libs though then even when no zlib is needed or used.
