Function Overview

Streaming is the process of collecting, encoding and packaging live content and then transmitting it to the Huawei Cloud Live center.

Streaming protocol: Real Time Messaging Protocol (RTMP)
Streaming tool: third-party streaming tools, such as Open Broadcaster Software (OBS), XSplit, and Flash Media Live Encoder (FMLE)

Playback is the process of playing live streams pushed from the streaming end. You can play live streams pushed from the Huawei Cloud Live or a third-party origin server.

Playback protocol: RTMP, HTTP-FLV, and HTTP Live Streaming (HLS)
Playback mode: Live supports third-party players such as VLC. LLL supports playback on web devices through online demos or open APIs.

You can record and store live content in Object Storage Service (OBS) buckets, where you can download and share the content.

You can transcode live streams into video streams with different resolutions and bitrates that fit the network conditions.

In the AP-Bangkok region, you need to submit a service ticket for configuration review. The transcoding configuration takes effect only after it is approved.

Live captures snapshots from a live stream based on a configured template and stores the captured snapshots in an OBS bucket. Multiple snapshot templates can be configured for a domain name. The template in which AppName is the same as that in the ingest URL takes effect.

In the AP-Bangkok region, you need to submit a service ticket for configuration review. The snapshot configuration takes effect only after it is approved.

You can add a callback URL on the Live console for receiving notifications when stream pushing starts or ends. The notifications are sent as POST requests to your server through an HTTP API. Then your server returns a status code to confirm that the notifications have been received.

In the AP-Bangkok region, you need to submit a service ticket for configuration review. The configuration of stream status notifications takes effect only after it is approved.

The playback latency of Live defaults to 2 seconds. You can change the value to 4 or 6 seconds. You can configure the latency for RTMP and HTTP-FLV streams. The keyframe interval of players cannot be greater than the configured latency. The actual latency is affected by factors such as the network status of the player.

By default, live content is pulled from Huawei origin servers. You can configure an origin address to pull live content from your own origin server to the Live center for distribution.

If you allow pulling live content from your own origin server for a streaming domain name, this streaming domain name cannot associate with any ingest domain name, and functions of Live cannot be used, such as transcoding, recording, snapshot capturing, and stream status notifications. The default origin port number is 80 for HTTP and 1935 for RTMP. If you use a non-default port as the origin port, submit a service ticket to bind the port with your origin server.

Live allows you to configure HTTPS secure acceleration for streaming domain names. You can configure your own SSL certificates or certificates purchased from Huawei Cloud on the Live console. Only certificates in PEM format are supported. You can also enable force redirect to forcibly redirect user requests to HTTPS.

Live provides referer validation, URL validation, and ACL to identify and filter out malicious visitors. Only authenticated visitors can use Live.

URL validation protects live resources from unauthorized download and theft. Referer validation uses referer blacklists/whitelists to prevent hotlinking. However, referer validation cannot well protect live resources because the referer content can be forged. As a result, you are advised to use URL validation.

URL validation: Both ingest and streaming URLs can be validated. You can customize the authentication key and expiration time and use multiple authentication algorithms provided by Live.
Referer validation: You can configure a referer blacklist or whitelist to identify and filter out malicious visitors.

ACL: You can configure an IP address blacklist or whitelist to identify and filter out malicious visitors.t.

You can view the downstream bandwidth/traffic statistics of all streaming domain names, and the total transcoding duration, maximum number of concurrent recording channels, and number of snapshots of all ingest domain names.

You can view the downstream bandwidth/traffic, playback profile, status codes returned in the request response of a streaming domain name, and the number of online viewers of the corresponding livestream. You can also view monitoring information such as the upstream bandwidth/traffic, total number of stream push channels, historical stream push details, and stream push frame rate/bitrate of an ingest domain name.

Live provides the log management function that allows you to view detailed logs about the network users' access to all streaming domain names and download logs of the past 90 days.

You can query and download logs in a time span of up to seven days. To query and download logs in a longer time span, repeat the operations.

Enterprise project is a method for managing resources and services in a unified manner. Resources and services in different regions can be added to the same enterprise project. For example, you can create several enterprise projects based on your company's divisions or projects, and then add your cloud resources and services to these enterprise projects accordingly.

When adding a domain name, you can specify an enterprise project to which the bucket will belong, to facilitate domain resource and permission management.
