Struct Wmv2Decoder 

pub struct Wmv2Decoder { /* private fields */ }

WMV2 (Windows Media Video 8) decoder.

The picture header parsing and macroblock decode paths are aligned with upstream.

Implementations

impl Wmv2Decoder

pub fn new(width: u32, height: u32, extradata: &[u8]) -> Self

Create a decoder for a fixed resolution.

extradata is the 4-byte WMV2 ext header typically carried in ASF stream properties.

pub fn width(&self) -> u32

pub fn height(&self) -> u32

pub fn current_frame(&self) -> &YuvFrame

Borrow the internal YUV420p frame buffer.

The returned reference stays valid until the next successful decode.

pub fn decode_frame( &mut self, payload: &[u8], is_key_frame: bool, ) -> Result<Option<&YuvFrame>>

Decode one assembled WMV2 frame payload.

Returns Ok(None) if no plausible picture header can be found.

pub fn decode_frame_owned( &mut self, payload: &[u8], is_key_frame: bool, ) -> Result<Option<YuvFrame>>

Decode and return an owned frame buffer (clone).
