Struct SubSampleInformationBoxEntry

pub struct SubSampleInformationBoxEntry {
    pub sample_delta: u32,
    pub subsample_count: u16,
    pub subsample_info: Vec<SubSampleInformationBoxEntrySubSample>,
}

Entry in SubSampleInformationBox.

Fields

sample_delta: u32

An integer that indicates the sample having sub‐sample structure. It is coded as the difference, in decoding order, between the desired sample number, and the sample number indicated in the previous entry. If the current entry is the first entry in the track, the value indicates the sample number of the first sample having sub-sample information, that is, the value is the difference between the sample number and zero (0). If the current entry is the first entry in a track fragment with preceding non-empty track fragments, the value indicates the difference between the sample number of the first sample having sub-sample information and the sample number of the last sample in the previous track fragment. If the current entry is the first entry in a track fragment without any preceding track fragments, the value indicates the sample number of the first sample having sub-sample information, that is, the value is the difference between the sample number and zero (0). This implies that the sample_delta for the first entry describing the first sample in the track or in the track fragment is always 1.

subsample_count: u16

An integer that specifies the number of sub-sample for the current sample. If there is no sub-sample structure, then this field takes the value 0.

subsample_info: Vec<SubSampleInformationBoxEntrySubSample>

subsample_size, subsample_priority, discardable and codec_specific_parameters.

Implementations

impl SubSampleInformationBoxEntry

pub fn size(&self, version: u8) -> usize

Returns the size of this entry in bytes, depending on the version.

Trait Implementations

impl Debug for SubSampleInformationBoxEntry

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

Formats the value using the given formatter.

impl<'a> DeserializeSeed<'a, u8> for SubSampleInformationBoxEntry

fn deserialize_seed<R: ZeroCopyReader<'a>>(reader: R, seed: u8) -> Result<Self>

Deserialize a value from the given zero-copy reader using the provided seed.

impl PartialEq for SubSampleInformationBoxEntry

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