Comment 3 for bug 195483

* I tried to add the "vbr=(0,2,3,4) parameter and the here are the results:

- vbr=0
  I obtain the same file with CBR 128 kbps (vbr=0 stands for no vbr!)

- vbr=2
  I obtain a 32 kbps CBR file with incorrect total lenght (7:28 instead of 1:42) (vbr=2 stands for use the old algorithm)

- vbr=3
  I obtain a 112 kbps CBR file with incorrect total lenght (1:51 instead of 1:42) (vbr=3 stands for use a medium bitrate)

- vbr=4
  I obtain a 32 kbps CBR file with incorrect total lenght (7:28 instead of 1:42) (vbr=4 stands for use the new algorithm)
