Members

hdr

VIDEOINFOHEADER2 structure.

dwStartTimeCode

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.
