Struct Decoder 

pub struct Decoder { /* private fields */ }

Implementations

impl Decoder

pub fn new<P: AsRef<Path>>(path: P) -> Result<Self>

pub fn container_metadata(&self) -> Result<ContainerMetadata>

pub fn timestamps(&self) -> Result<Vec<i64>>

pub fn prefetch(&self, timestamp_ns: i64)

Hint the OS to prefetch a frame’s range into the page cache (B4). See motioncam_decoder::Decoder::prefetch. No-op on Windows.

pub fn load_frame(&self, timestamp_ns: i64) -> Result<(Vec<u16>, FrameMetadata)>

pub fn load_frame_into( &self, timestamp_ns: i64, out: &mut [u16], ) -> Result<[f32; 3]>

Decode a frame into a caller-owned buffer (B1). Returns only the asShotNeutral triplet (B2) — the only metadata the export hot path uses. Use load_frame if you need the other fields.

pub fn load_frame_metadata(&self, timestamp_ns: i64) -> Result<FrameMetadata>

pub fn write_audio_to<W: Write>(&self, writer: &mut W) -> Result<()>

Write all audio chunks to writer as raw s16le PCM, one chunk at a time. Never holds more than one chunk in memory — safe for long recordings. The caller should wrap the file in a BufWriter for decent I/O coalescing.
