Struct Av1Clip 

pub struct Av1Clip {
    pub width: u32,
    pub height: u32,
    pub fps: u32,
    pub frames: Vec<Vec<u8>>,
}

An AV1 stream: one temporal unit (the OBUs of one picture) per frame.

Fields

width: u32

height: u32

fps: u32

frames: Vec<Vec<u8>>

Implementations

impl Av1Clip

pub fn from_ivf(b: &[u8]) -> Option<Self>

Parses an IVF file (32-byte header, then a 12-byte header before each frame) holding AV1 at a whole number of frames per second.

pub fn is_key(&self, i: usize) -> bool

Whether frame i starts a new sequence: it carries a sequence header, which encoders (rav1e among them) repeat at each keyframe.

pub fn av1c(&self) -> Vec<u8>

The av1C record (AV1 codec configuration) that MP4 and Matroska carry: profile, level and tier read from the sequence header, the colour fields for 8-bit 4:2:0, and the sequence header OBU itself.

pub fn matroska(&self, webm: bool) -> Vec<u8>

The clip as a WebM (webm) or Matroska file: one cluster per keyframe, with cues pointing at them.

pub fn mp4(&self) -> Vec<u8>

The clip as an MP4 file: moov first, then one chunk of samples in mdat, with keyframes listed in stss.
