Pearl Mini User Guide Set up an HLS (push) stream
HLS uses an MPEG2-TS transport stream container with a configurable media segment duration, as well as a
configurable playlist size for reassembling the media segments at the ingestion server. Because HLS favors
Quality of Service (QoS) over low-latency, lag times that can be high. If a specific media segment size isn't
required by the ingestion server, then you can shorten the duration of the media segment to decrease latency.
The default segment duration is six seconds.
Using the Admin panel, you can add advanced features like a master manifest, which is an address applied to
each individual media playlist in the stream. You can also assign the HLS stream a user name and password. If
security and authentication credentials are required to stream to the ingestion server, consult the ingestion
server provider.
Important considerations
l Only a single resolution and bitrate stream is supported.
l See Suggested stream settings for the best streaming settings for Pearl Mini.
l Fragmented MP4 is not supported.
l If the HLS ingestion server requires a custom user-agent name, add that to the HLS stream in the
Advanced settings using the Admin panel and ensure the agent-name is added to the HLS ingestion
server's white list. Contact the IT administrator responsible for the ingestion server.
l If the HLS ingestion server requires a user name and password, you can get those credentials from the IT
administrator responsible for the ingestion server.
