Struct Vc1PictureHeader 

pub struct Vc1PictureHeader {
    pub fcm: u8,
    pub picture_type: u8,
}

Minimal picture header (§7.1.1). Picture-type decode in VC-1 is VLC-coded and depends on the entry-point’s interlace flag, the sequence header’s finterpflag, etc. We surface only the FCM (frame coding mode) and the picture type, which is what VdpPictureInfoVC1::picture_type ultimately consumes.

Fields

fcm: u8

FCM — frame coding mode (§7.1.1.15). 0 = progressive frame, 2 = interlaced field, 3 = interlaced frame.

picture_type: u8

Picture type: 0=I, 1=P, 2=B, 3=BI, 4=skipped (for progressive pictures). For interlaced field pictures this is per-field and uses different VLC; the parser falls back to a 3-bit fixed-length read for those.
