Struct H264Decoder 

pub struct H264Decoder { /* private fields */ }

Baseline H.264 decoder.

Parses SPS/PPS from the bitstream to determine frame dimensions. Decodes I-slice macroblocks using CAVLC entropy decoding with full coefficient reconstruction (I_PCM, I_16x16, I_4x4 macroblock types), 4x4 inverse DCT, dequantization, and DC prediction for both luma and chroma planes. P-slice motion compensation and B-slice bidirectional prediction are handled by companion modules (h264_motion, h264_bslice). Deblocking is provided by h264_deblock.

Implementations

impl H264Decoder

pub fn new() -> Self

pub fn process_nal( &mut self, nal: &NalUnit, ) -> Result<Option<DecodedFrame>, VideoError>

Trait Implementations

impl Default for H264Decoder

fn default() -> Self

Returns the “default value” for a type.

impl VideoDecoder for H264Decoder

fn codec(&self) -> VideoCodec

fn decode( &mut self, data: &[u8], timestamp_us: u64, ) -> Result<Option<DecodedFrame>, VideoError>

Decode a single compressed access unit into an RGB8 frame. Returns None if the decoder needs more data (e.g., initial SPS/PPS).

fn flush(&mut self) -> Result<Vec<DecodedFrame>, VideoError>

Flush any remaining buffered frames.
