Set up an HLS (push) stream
HTTP Live Streaming (HLS) is an adaptive, HTTP-based streaming protocol that sends video and audio
content over the network in small, media segments that get reassembled at the streaming destination.
Media segments stream over HTTP port 80 or port 443 for HTTPS, which are typically open for network
access. As such, the content can easily traverse firewalls with little to no IT involvement.
Pearl Mini can send a single resolution and bitrate HLS stream as an HTTP POST (or HTTP PUT) to HLS
ingestion servers and CDNs such as Akamai and YouTube. The default is HTTP POST. Your channels on
Pearl Mini must be configured for H.264 and AAC audio codec to stream using HLS. Pearl Mini supports
MD5, SHA-256, and SHA-512 hashing algorithms to authenticate the 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
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.
