MediaStreamAudio Struct
A media stream represents one component of your content, such as video, audio, or ancillary data.
After you add a media stream to your flow, you can associate it with sources and outputs that use the ST 2110 JPEG XS or CDI protocol.
Example
ts
declare const stack: Stack;
// Create media streams
const videoStream = MediaStream.video({
mediaStreamId: 1,
mediaStreamName: 'video-stream',
videoFormat: MediaVideoFormat.HD_1080P,
fmtp: {
colorimetry: Colorimetry.BT709,
exactFramerate: Framerate.FPS_29_97,
par: PixelAspectRatio.SQUARE,
videoRange: VideoRange.NARROW,
scanMode: ScanMode.PROGRESSIVE,
tcs: Tcs.SDR,
},
});
const audioStream = MediaStream.audio({
mediaStreamId: 2,
mediaStreamName: 'audio-stream',
channelOrder: AudioStreamOrderOptions.STANDARD_STEREO,
});
// Add to flow
const flow = new Flow(stack, 'MyFlow', {
source: SourceConfiguration.router(),
mediaStreams: [videoStream, audioStream], // Declare at flow level
});
