/* About XviD VBR Library, Edouard Gomez (GomGom) said:
  <GomGom> header bytes == frame header bytes :-)
  <GomGom> total bytes = frame bytes == texture + header
  <GomGom> quant = quant returned by xvidcore
  <GomGom> it's possible that xvid lowers or increases the passed quant because of lumimasking
  <GomGom> kblks = blocks coded as intra blocks
  <GomGom> mblks = blocks coded as predicted blocks
  <GomGom> ublks = skipped blocks
  <GomGom> at the moemnt le vbr lib uses total bytes, and quant
  <GomGom> so it's easy to use it with divx5 (wo bframes)
  <klOUg> bframes breaks what assumptions?
  <GomGom> quant estimation for next frame
  <GomGom> because of the bframe quant multiplier given to divx5
  <GomGom> that the vbr lib does not "know"
