Timed metadata allows you to build interactivity into live streams. Wowza Streaming Engine™ media server software, the Wowza Streaming Cloud™ service, Wowza GoCoder™ SDK, and Wowza™ Player all support timed metadata in streaming workflows.
The three core workflows are:
Wowza Streaming Engine to Wowza Streaming Cloud
Ingest (or inject) AMF metadata into Wowza Streaming Engine and send it to Wowza Streaming Cloud. In Wowza Streaming Cloud, convert the AMF metadata into ID3 tags, transcode the stream into adaptive-bitrate renditions, and send the renditions with the timed metadata to a CDN edge resource using HLS.
Wowza Streaming Engine to a Wowza CDN or HLS stream target
Ingest (or inject) AMF metadata into Wowza Streaming Engine. Convert the AMF metadata to ID3 and send the ID3 tags with transcoded output renditions for HLS delivery using a Wowza CDN or other edge resource.
Wowza Streaming Cloud with Ultra Low Latency
Ingest AMF metadata into a Wowza Streaming Cloud Ultra Low Latency Stream Target. Pass the AMF data to the ultra low latency edge server with the WOWZ stream, and convert it to ID3 and send those tags with the HLS backup stream.
