Struct SampleSizeAtom 

pub struct SampleSizeAtom {
    pub version: u8,
    pub flags: [u8; 3],
    pub sample_size: u32,
    pub sample_count: u32,
    pub entry_sizes: SampleEntrySizes,
}

Sample Size Atom (stsz) - ISO/IEC 14496-12 This atom contains the sample count and a table giving the size in bytes of each sample. Samples within the media may have different sizes, up to the limit of a 32-bit integer.

Fields

version: u8

flags: [u8; 3]

sample_size: u32

If this field is set to some value other than 0, then it gives the (constant) size of every sample in the track. If this field is set to 0, then the samples have different sizes, and those sizes are stored in the sample size table.

sample_count: u32

Number of samples in the track

entry_sizes: SampleEntrySizes

If sample_size is 0, this contains the size of each sample, indexed by sample number. If sample_size is non-zero, this table is empty.

Implementations

impl SampleSizeAtom

pub fn sample_count(&self) -> usize

Returns sample_count if it’s set, otherwise entry_sizes.len()

impl SampleSizeAtom

pub fn sample_sizes(&self) -> impl Iterator<Item = &u32> + '_

Returns an iterator over all sample sizes.

If sample_size != 0 this will repeat that value sample_count times; otherwise it will yield the values from entry_sizes.

pub fn builder() -> SampleSizeAtomBuilder
