[x264-devel] Regarding disabling 4x4 in JM code

[mahesh k]

thanks for ur reply. Plz tell me whether intra 4x4 is must in base line
profile or it is an optional.
 Can't we run the baseline profile decoder without 4x4 as per standard?
I need this because at present we have not implemented this 4x4 mode But we
want to decode any standard bitstream that is as per standard but return the
error code accordingly .
Also I am confused with the syntax element mb_type.
What values does mb_type should have if i need to check whether this is an
4x4 or 16x16.
Also plz tell me in clear about this mb_type and ma_mde.
If possible refer some good document on this.

Thanks in advance.
