Fields

frame_type: FrameType

pqindex: u8

pquant: u8

halfqp: bool

pqual_mode: u8

mvrange: u8

rptfrm: u8

pts_ms: u32

rangeredfrm: bool

header_bits: usize

Bit offset where the macroblock layer starts (from beginning of the frame payload).

This includes the full picture header and any bitplanes decoded from it.

skipmb_plane: Option<Vec<u8>>

Skipped-MB bitplane (None if not present or raw-mode)

directmb_plane: Option<Vec<u8>>

Direct-mode bitplane for B-frames

bfrac_num: i32

B-frame temporal fraction from SMPTE 421M §7.1.3.6 Table 40.

bfrac_den: i32
