[M4IF Technotes] question about intra_dc_vlc_thr2

[Kumar, Gautam]

Kosuge-San,
intra_vlc_format is function of intra_dc_vlc_thr and qp.
if intra_vlc_format = 1 and mbintra = 1 ==> dc value is encoded using ac
table (table B-16).
last need not to be zero. run is always zero for this, as this is the first
element.
i think, escape code should be used if it falls outside the table range.
Warm Regards,
Gautam
