VideoTrackInfo

Remarks

A record rather than the container's own track type, so that a codec never references a demuxer. That is not tidiness: it is what lets an MP4 reader arrive later and reuse every codec anybody has written against this.

Fields and properties (8)

• public string CodecId

  What the container called it — V_VP9, V_UNCOMPRESSED. Matroska's spelling is used even by a container that spells it differently, because a registry has to agree on one.

• public int Width

  The coded width in samples.

• public int Height

  The coded height in samples.

• public ReadOnlyMemory<byte> CodecPrivate

  The codec's own header, or empty if it needs none.

• public string FourCc

  The sample format of an uncompressed track, or empty.

• public VideoRational FrameRate

  The nominal rate, or unknown.

• public VideoColourRange Range

  What range the container said the samples use.

• public VideoColourMatrix Matrix

  What coefficients it said they were made with.
