public sealed class ElementaryStream : IMessage<ElementaryStream>, IEquatable<ElementaryStream>, IDeepCloneable<ElementaryStream>, IBufferMessage, IMessage
Reference documentation and code samples for the Live Stream v1 API class ElementaryStream.
Encoding of an input element such as an audio, video, or text track.
Elementary streams must be packaged before mapping and sharing between
different output formats.
A unique key for this elementary stream. The key must be 1-63
characters in length. The key must begin and end with a letter (regardless
of case) or a number, but can contain dashes or underscores in between.
