Implementations

impl MacroblockDecoder

pub fn new(width: u32, height: u32) -> Self

pub fn decode_frame( &mut self, payload: &[u8], pic_hdr: &PictureHeader, seq: &SequenceHeader, frame: &mut YuvFrame, ) -> Result<()>

impl MacroblockDecoder

pub fn wmv2_set_extradata(&mut self, extradata: &[u8])

Decode one WMV2 frame. hdr is the already-parsed per-frame header. This is the public entry point called from main.rs. Parse WMV2 ext-header from ASF extradata (upstream decode_ext_header).

If extradata is missing/short, we keep all flags at default false.

pub fn wmv2_copy_ref(&self, out: &mut YuvFrame) -> bool

pub fn decode_wmv2_frame( &mut self, payload: &[u8], hdr: &Wmv2FrameHeader, params: &Wmv2Params, frame: &mut YuvFrame, ) -> Result<()>

pub fn probe_wmv2_payload(&self, payload: &[u8], hdr: &Wmv2FrameHeader) -> usize

Heuristic probe: try to parse a few macroblock headers after hdr.header_bits. Used to disambiguate ASF framing-byte offsets when the picture header can be (mis-)parsed at multiple byte offsets.

Returns a “score” = number of MB headers successfully parsed (higher is better).
