Visual sample entry

ISO/IEC 14496-12 - 12.1.3

Sub boxes:

• btrt
• clap
• pasp
• colr
• clli
• mdcv
• cclv
• amve
• Any other boxes

Fields

sample_entry: SampleEntry

The sample entry that this box inherits from.

pre_defined: u16

Pre-defined 16 bits, must be 0.

reserved1: u16

Reserved 16 bits, must be 0.

pre_defined2: [u32; 3]

Pre-defined 3 * 32 bits, must be 0.

width: u16

The maximum visual width and height of the stream described by this sample description, in pixels.

height: u16

See width.

horiz_resolution: FixedU32<U16>

Must be set to 0x00480000 (72 dpi).

vert_resolution: FixedU32<U16>

Must be set to 0x00480000 (72 dpi).

reserved2: u32

Reserved 32 bits, must be 0.

frame_count: u16

How many frames of compressed video are stored in each sample. The default is 1, for one frame per sample; it may be more than 1 for multiple frames per sample.

compressor_name: [u8; 32]

A name, for informative purposes. It is formatted in a fixed 32-byte field, with the first byte set to the number of bytes to be displayed, followed by that number of bytes of displayable data encoded using UTF-8, and then padding to complete 32 bytes total (including the size byte). The field may be set to 0.

depth: u16

One of the following values:

• 0x0018: images are in colour with no alpha.

pre_defined4: i16

Pre-defined 16 bits, must be -1.

Implementations

impl VisualSampleEntry

pub fn new( sample_entry: SampleEntry, width: u16, height: u16, compressor_name: [u8; 32], ) -> Self

Creates a new VisualSampleEntry with the given parameters.

Trait Implementations

impl Debug for VisualSampleEntry

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for VisualSampleEntry

fn deserialize<R>(reader: R) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl IsoSized for VisualSampleEntry

fn size(&self) -> usize

Returns the size of the type when serialized.

impl PartialEq for VisualSampleEntry

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

impl Serialize for VisualSampleEntry

fn serialize<W>(&self, writer: W) -> Result<()>

where W: Write,

Serialize the value into the given writer.

impl Eq for VisualSampleEntry

impl StructuralPartialEq for VisualSampleEntry
