Members

hdr
Compatible with VIDEOINFOHEADER2.
dwStartTimeCode
25-bit "group-of-pictures" time code at start of data (not used for DVD).
cbSequenceHeader
Length in bytes of dwSequenceHeader (zero for DVD).
dwProfile
MPEG2Profile enumerated type member.
dwLevel
MPEG2Level enumerated type member.
dwFlags
Flag indicating preferences. Set one or a combination of the following values.

AMMPEG2_DoPanScan If set, the MPEG-2 video decoder should crop the output image based on pan-scan vectors in the picture display extension and change the picture aspect ratio accordingly.
AMMPEG2_DVDLine21Field1 If set, the MPEG-2 decoder must be able to produce an output pin for DVD style closed-captioned data found in the Group Of Pictures (GOP) layer of field 1.
AMMPEG2_DVDLine21Field2 If set, the MPEG-2 decoder must be able to produce an output pin for DVD style closed-captioned data found in the GOP layer of field 2.
AMMPEG2_SourceIsLetterboxed If set, indicates that black bars have been encoded in the top and bottom of the video.
AMMPEG2_FilmCameraMode If set, indicates "film mode" used for the 625/50 (line/field) content. If cleared, indicates that "camera mode" was used.

Set undefined flags to zero or connection will be rejected.

dwSequenceHeader
Sequence header including quantization matrices, if any.

AMMPEG2_DoPanScan	If set, the MPEG-2 video decoder should crop the output image based on pan-scan vectors in the picture display extension and change the picture aspect ratio accordingly.
AMMPEG2_DVDLine21Field1	If set, the MPEG-2 decoder must be able to produce an output pin for DVD style closed-captioned data found in the Group Of Pictures (GOP) layer of field 1.
AMMPEG2_DVDLine21Field2	If set, the MPEG-2 decoder must be able to produce an output pin for DVD style closed-captioned data found in the GOP layer of field 2.
AMMPEG2_SourceIsLetterboxed	If set, indicates that black bars have been encoded in the top and bottom of the video.
AMMPEG2_FilmCameraMode	If set, indicates "film mode" used for the 625/50 (line/field) content. If cleared, indicates that "camera mode" was used.
