public sealed class Channel : IMessage<Channel>, IEquatable<Channel>, IDeepCloneable<Channel>, IBufferMessage, IMessage
Reference documentation and code samples for the Live Stream v1 API class Channel.
Channel resource represents the processor that does a user-defined
"streaming" operation, which includes getting an input stream through an
input, transcoding it to multiple renditions, and publishing output live
streams in certain formats (for example, HLS or DASH) to the specified
location.
Output only. The
[InputAttachment.key][google.cloud.video.livestream.v1.InputAttachment.key]
that serves as the current input source. The first input in the
[input_attachments][google.cloud.video.livestream.v1.Channel.input_attachments]
is the initial input source.
public RepeatedField<Encryption> Encryptions { get; }
Encryption configurations for this channel. Each configuration has an ID
which is referred to by each MuxStream to indicate which configuration is
used for that output.
public RepeatedField<InputAttachment> InputAttachments { get; }
A list of input attachments that this channel uses.
One channel can have multiple inputs as the input sources. Only one
input can be selected as the input source at one time.
Output only. A description of the reason for the streaming error. This
property is always present when
[streaming_state][google.cloud.video.livestream.v1.Channel.streaming_state]
is
[STREAMING_ERROR][google.cloud.video.livestream.v1.Channel.StreamingState.STREAMING_ERROR].
