/* 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"
