Struct AvcConfig 

pub struct AvcConfig {
    pub nal_length_size: usize,
    pub sps: Vec<Vec<u8>>,
    pub pps: Vec<Vec<u8>>,
}

Available on crate features codec-h264 and codec only.

Parsed AVC decoder configuration (the avcC record from a video sequence header / AVCDecoderConfigurationRecord), retaining the parameter sets needed to (a) build Annex-B config for a decoder and (b) self-contain each keyframe.

Lives in the codec layer (not a protocol module) so every consumer — the RTMP FLV path, the transcode pipeline, and any host — shares one parser.

Fields

nal_length_size: usize

NAL length prefix width in bytes (lengthSizeMinusOne + 1).

sps: Vec<Vec<u8>>

Sequence parameter sets.

pps: Vec<Vec<u8>>

Picture parameter sets.

Implementations

impl AvcConfig

pub fn parse(rec: &[u8]) -> Option<Self>

Parse an AVCDecoderConfigurationRecord (avcC). Returns None if the buffer is too short or its configurationVersion is not 1.

pub fn to_annexb(&self) -> Bytes

The SPS/PPS as an Annex-B access unit (each NAL prefixed with 00 00 00 01).

pub fn to_avc_record(&self) -> Bytes

Rebuild an AVCDecoderConfigurationRecord from the stored parameter sets (used when serving a play request).

pub fn avcc_to_annexb(&self, avcc: &[u8], prepend_params: bool) -> Option<Bytes>

Build an Annex-B access unit from length-prefixed (AVCC) NAL data, optionally prepending SPS/PPS so a keyframe is self-decodable.

Trait Implementations

impl Clone for AvcConfig

fn clone(&self) -> AvcConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AvcConfig

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

Formats the value using the given formatter.

impl Default for AvcConfig

fn default() -> AvcConfig

Returns the “default value” for a type.

impl Eq for AvcConfig

impl PartialEq for AvcConfig

fn eq(&self, other: &AvcConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
