Implementations

impl SequenceHeader

pub fn parse(data: &[u8]) -> Result<Self>

pub fn parse_wvc1(data: &[u8]) -> Result<Self>

Parse VC-1 Advanced Profile private data carried by WVC1.

WVC1 ASF stream properties contain VC-1 start-code-delimited sequence and entry-point units (the first byte is commonly the private-data length). This follows FFmpeg’s VC1/WVC1 initialization path: locate the 0x0000010f sequence header and 0x0000010e entry point, remove VC-1 emulation-prevention bytes from each payload, then parse both units.

pub fn apply_wvc1_entry_point(&mut self, data: &[u8]) -> Result<()>

pub fn uses_transposed_scans(&self) -> bool

Trait Implementations

impl Clone for SequenceHeader

fn clone(&self) -> SequenceHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SequenceHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
