Fields

crc32: Option<Crc32>

Optional CRC-32 element for integrity checking.

void: Option<Void>

void element, useful for reserving space during writing.

flag_interlaced: FlagInterlaced

Specify whether the video frames in this track are interlaced.

• 0 - undetermined,
• 1 - interlaced,
• 2 - progressive

field_order: FieldOrder

Specify the field ordering of video frames in this track. If FlagInterlaced is not set to 1, this Element MUST be ignored.

• 0 - progressive,
• 1 - tff,
• 2 - undetermined,
• 6 - bff,
• 9 - bff(swapped),
• 14 - tff(swapped)

stereo_mode: StereoMode

Stereo-3D video mode. There are some more details in notes.

• 0 - mono,
• 1 - side by side (left eye first),
• 2 - top - bottom (right eye is first),
• 3 - top - bottom (left eye is first),
• 4 - checkboard (right eye is first),
• 5 - checkboard (left eye is first),
• 6 - row interleaved (right eye is first),
• 7 - row interleaved (left eye is first),
• 8 - column interleaved (right eye is first),
• 9 - column interleaved (left eye is first),
• 10 - anaglyph (cyan/red),
• 11 - side by side (right eye first),
• 12 - anaglyph (green/magenta),
• 13 - both eyes laced in one Block (left eye is first),
• 14 - both eyes laced in one Block (right eye is first)

alpha_mode: AlphaMode

Indicate whether the BlockAdditional Element with BlockAddID of “1” contains Alpha data, as defined by to the Codec Mapping for the CodecID. Undefined values SHOULD NOT be used as the behavior of known implementations is different (considered either as 0 or 1).

• 0 - none,
• 1 - present

pixel_width: PixelWidth

Width of the encoded video frames in pixels.

pixel_height: PixelHeight

Height of the encoded video frames in pixels.

pixel_crop_bottom: PixelCropBottom

The number of video pixels to remove at the bottom of the image.

pixel_crop_top: PixelCropTop

The number of video pixels to remove at the top of the image.

pixel_crop_left: PixelCropLeft

The number of video pixels to remove on the left of the image.

pixel_crop_right: PixelCropRight

The number of video pixels to remove on the right of the image.

display_width: Option<DisplayWidth>

Width of the video frames to display. Applies to the video frame after cropping (PixelCrop* Elements). If the DisplayUnit of the same TrackEntry is 0, then the default value for DisplayWidth is equal to PixelWidth - PixelCropLeft - PixelCropRight, else there is no default value.

display_height: Option<DisplayHeight>

Height of the video frames to display. Applies to the video frame after cropping (PixelCrop* Elements). If the DisplayUnit of the same TrackEntry is 0, then the default value for DisplayHeight is equal to PixelHeight - PixelCropTop - PixelCropBottom, else there is no default value.

display_unit: DisplayUnit

How DisplayWidth & DisplayHeight are interpreted.

• 0 - pixels,
• 1 - centimeters,
• 2 - inches,
• 3 - display aspect ratio,
• 4 - unknown

uncompressed_fourcc: Option<UncompressedFourcc>

Specify the uncompressed pixel format used for the Track’s data as a FourCC. This value is similar in scope to the biCompression value of AVI’s BITMAPINFO [@?AVIFormat]. There is no definitive list of FourCC values, nor an official registry. Some common values for YUV pixel formats can be found at [@?MSYUV8], [@?MSYUV16] and [@?FourCC-YUV]. Some common values for uncompressed RGB pixel formats can be found at [@?MSRGB] and [@?FourCC-RGB]. UncompressedFourCC MUST be set in TrackEntry, when the CodecID Element of the TrackEntry is set to “V_UNCOMPRESSED”.

colour: Option<Colour>

Settings describing the colour format.

projection: Option<Projection>

Describes the video projection details. Used to render spherical, VR videos or flipping videos horizontally/vertically.

Trait Implementations

impl Clone for Video

fn clone(&self) -> Video

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Video

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

Formats the value using the given formatter.

impl Default for Video

fn default() -> Video

Returns the “default value” for a type.

impl Element for Video

const ID: VInt64

EBML ID of the element.

fn decode_body(buf: &mut &[u8]) -> Result<Self>

Decode the body of the element from a buffer.

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

Encode the body of the element to a buffer.

const HAS_DEFAULT_VALUE: bool = false

Whether the element has a default value, as per Matroska specification. If true, and the element is missing in a master element, it should be treated as if it were present with the default value. If false, and the element is missing in a master element, it should be treated as an error.

impl PartialEq for Video

fn eq(&self, other: &Video) -> 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 StructuralPartialEq for Video
