Crate mp4parse

Module for parsing ISO Base Media Format aka video/mp4 streams.

Structs

• ALACSpecificBox
  Represent an ALACSpecificBox ‘alac’
• AV1ConfigBox
  See AV1-ISOBMFF § 2.3.3
• AudioSampleEntry
• AuxiliaryTypeProperty
  See HEIF (ISO 23008-12:2017) § 6.5.8
• AvifContext
• ChunkOffsetBox
• CompositionOffsetBox
• ES_Descriptor
  An Elementary Stream Descriptor See MPEG-4 Systems (ISO 14496-1:2010) § 7.2.6.5
• FLACMetadataBlock
• FLACSpecificBox
  Represents a FLACSpecificBox ‘dfLa’
• IccColourInformation
  The raw bytes of the ICC profile
• ImageSpatialExtentsProperty
• ItemPropertiesBox
  See ISOBMFF (ISO 14496-12:2020) § 8.11.14.1
• Matrix
• MediaContext
  Internal data structures.
• MediaScaledTime
  A time to be scaled by the media’s global (mvhd) timescale.
• MediaTimeScale
  The media’s global (mvhd) timescale in units per second.
• MetadataBox
  Represents the contents of ‘ilst’ atoms within a metadata box ‘meta’, parsed as iTunes metadata using the conventional tags.
• MovieExtendsBox
• NclxColourInformation
  Despite Rec. ITU-T H.273 (12/2016) defining the CICP fields as having a range of 0-255, and only a small fraction of those values being used, ISOBMFF (ISO 14496-12:2020) § 12.1.5 defines them as 16-bit values in the colr box. Since we have no use for the additional range, and it would complicate matters later, we fallibly convert before storing the input.
• OpusSpecificBox
  Represent an OpusSpecificBox ‘dOps’
• PixelAspectRatio
• PixelInformation
• ProtectionSchemeInfoBox
• ProtectionSystemSpecificHeaderBox
• Sample
• SampleDescriptionBox
• SampleSizeBox
• SampleToChunk
• SampleToChunkBox
• SchemeTypeBox
• SyncSampleBox
• TimeOffset
• TimeToSampleBox
• Track
• TrackEncryptionBox
• TrackHeaderBox
  Track header box ‘tkhd’
• TrackReference
• TrackReferenceBox
• TrackScaledTime
  A time to be scaled by the track’s local (mdhd) timescale. Members are time in scale units and the track id.
• TrackTimeScale
  The track’s local (mdhd) timescale. Members are timescale units per second and the track id.
• UnsupportedFeatures
  A collection to indicate unsupported features that were encountered during parsing. Since the default behavior for many such features is to ignore them, this often not fatal and there may be several to report.
• UserdataBox
  Represents a userdata box ‘udta’. Currently, only the metadata atom ‘meta’ is parsed.
• VPxConfigBox
  Represent a Video Partition Codec Configuration ‘vpcC’ box (aka vp9). The meaning of each field is covered in detail in “VP Codec ISO Media File Format Binding”.
• VideoSampleEntry

Enums

• AdvisoryRating
  Represents the parental advisory rating on the track, stored within the ‘rtng’ atom.
• AudioCodecSpecific
• CodecType
• ColourInformation
• Error
  Describes parser failures.
• Feature
• Genre
  Represents possible contents of the ©gen or gnre atoms within a metadata box. ‘udta.meta.ilst’ may only have either a standard genre box ‘gnre’ or a custom genre box ‘©gen’, but never both at once.
• ImageMirror
  The axis about which the image is mirrored (opposite of flip) Visualized in terms of starting with (⥠) UPWARDS HARPOON WITH BARB LEFT FROM BAR similar to a DIGIT ONE (1)
• ImageRotation
  Rotation in the positive (that is, anticlockwise) direction Visualized in terms of starting with (⥠) UPWARDS HARPOON WITH BARB LEFT FROM BAR similar to a DIGIT ONE (1)
• ItemProperty
  See ISOBMFF (ISO 14496-12:2020) § 8.11.14.1 Variants with no associated data are recognized but not necessarily supported. See Feature to determine support.
• MediaType
  Represents the contents of a ‘stik’ atom that indicates content types within iTunes.
• ParseStrictness
• SampleEntry
• Status
  The return value to the C API Any detail that needs to be communicated to the caller must be encoded here since the Error type’s associated data is part of the FFI.
• TimeOffsetVersion
• TrackReferenceEntry
• TrackType
• VideoCodecSpecific

Constants

• AVIF_BRAND
  The brand to identify AV1 image items The ‘avif’ brand indicates structural requirements on files See https://aomediacodec.github.io/av1-avif/#image-and-image-collection-brand
• AVIS_BRAND
  The brand to identify AVIF image sequences The ‘avis’ brand indicates structural requirements on files See https://aomediacodec.github.io/av1-avif/#image-and-image-collection-brand
• MIF1_BRAND
  The HEIF image and image collection brand The ‘mif1’ brand indicates structural requirements on files See HEIF (ISO 23008-12:2017) § 10.2.1
• MSF1_BRAND
  The HEIF image sequence brand The ‘msf1’ brand indicates structural requirements on files See HEIF (ISO 23008-12:2017) § 10.3.1

Traits

• ToUsize
  A trait to indicate a type can be infallibly converted to usize. This should only be implemented for infallible conversions, so only unsigned types are valid.

Functions

• read_avif
  Read the contents of an AVIF file
• read_mp4
  Read the contents of a box, including sub boxes.
• serialize_opus_header
  Re-serialize the Opus codec-specific config data as an OpusHead packet.

Type Definitions

• ByteData
• Result
  Result shorthand using our Error enum.
• TryBox
• TryHashMap
• TryString
• TryVec
