Struct Pcm 

pub struct Pcm {
    pub fourcc: FourCC,
    pub audio: Audio,
    pub pcmc: Option<PcmC>,
    pub chnl: Option<Chnl>,
    pub btrt: Option<Btrt>,
}

Fields

fourcc: FourCC

audio: Audio

pcmc: Option<PcmC>

chnl: Option<Chnl>

btrt: Option<Btrt>

Implementations

impl Pcm

pub fn decode_with_fourcc<B: Buf>(fourcc: FourCC, buf: &mut B) -> Result<Self>

pub fn encode_with_fourcc<B: BufMut>(&self, buf: &mut B) -> Result<()>

pub fn format(&self) -> Option<PcmFormat>

Returns the resolved sample format of this entry.

The pcmC box wins when present. Otherwise the format implied by the fourcc is used:

• twos: big-endian integer, sample_size bits (8 or 16 per QTFF-2001)
• sowt: little-endian integer, sample_size bits (8 or 16 per QTFF-2001)
• in24 / in32: big-endian integer, 24 / 32 bits
• fl32 / fl64: big-endian float, 32 / 64 bits
• s16l: little-endian integer, 16 bits
• lpcm: QTFF format flags are only defined for version 2 sound sample descriptions, which are not decoded here; defaults to big-endian integer, sample_size bits

Returns None for an unknown fourcc, or for an ipcm/fpcm entry missing its mandatory pcmC box (which decode_with_fourcc never produces).

Trait Implementations

impl Clone for Pcm

fn clone(&self) -> Pcm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pcm

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

Formats the value using the given formatter.

impl Eq for Pcm

impl PartialEq for Pcm

fn eq(&self, other: &Pcm) -> 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.
