[vlc-devel] Re: Trick mode support for MPEG2 TS

[yj]

But I found the following sentence in 6.3.9:

picture_coding_type -- The picture_coding_type
identifies whether a picture is an intra-coded
picture(I),
predictive-coded picture(P) or bidirectionally
predictive-coded picture(B).

It seems that the field picture_coding_type is the
indicator, isn't it?
