[Mp4-tech] How to play with INTRA_DC_VLC_THR to improve coding efficiency?

[Lefan Zhong]

Hi,
It is very tricky to implement INTRA_DC_VLC_THR, even Momusys reference code
cannot handle it correcly for some corner cases (when first MB in a packet
is skipped).
Does anyone know any reference about the compression improvement with this
complex INTRA_DC_VLC_THR? Or any story about it is in the standard simple
profile?
Thanks,
Lefan
