Live Streaming Data Transfer Plan: Billing

Live streaming data transfer plans support only the pay-per-daily-traffic billing pattern.

No.

Resource plan details

You can query for currently valid resource plans and resource plans that expired within the last year.

No.

Pay-by-traffic

If you use the pay-by-traffic billing method, the maximum bandwidth is 10 Gbit/s by default.

If you need assistance, submit a ticket.

Bandwidth throttling

According to the Product-Specific Terms in the Alibaba Cloud International Website Product Terms of Service, if the billing method for network usage of your domain name is pay-by-traffic or pay-by-bandwidth and the bandwidth consumed within 1 minute increases by 10 Gbit/s, Alibaba Cloud enables bandwidth throttling for the domain name to prevent potential attacks from harming your network or impacting your business.

To disable bandwidth throttling or if throttling was triggered erroneously, contact your account manager or submit a ticket.

Accelerated domain name

• If the acceleration region of your domain name is Global or Chinese Mainland, the domain name must have an ICP filing. For more information, see Domain name ICP filing.

• By default, you can add up to 20 accelerated domain names to ApsaraVideo Live within each Alibaba Cloud account.

If you have any questions, please submit a ticket.

Live stream ingest

• For live centers in the China (Beijing), China (Shanghai), and China (Shenzhen) regions, each accelerated domain name supports concurrent ingest of up to 300 source streams by default.

• For live centers in other regions, each accelerated domain name supports concurrent ingest of up to 50 source streams by default.

• For live centers in the China (Beijing), China (Shanghai), China (Shenzhen), and Singapore regions, go to the Quota Center to apply for a quota increase. For more information, see Quota management.

• For live centers in other regions, if you want to increase the quota, contact your account manager or submit a ticket.

ApsaraVideo Live does not limit the bitrate of ingested streams and supports common resolutions and bitrates. To prevent stuttering during stream ingest, we recommend that you use a bitrate of 4 Mbit/s or less.

No.

The RTMP, ARTC, and SRT protocols are supported for stream ingest.

No.

Live stream playback

The RTMP, FLV, HLS, ARTC, SRT, and CMAF protocols are supported for streaming. The SRT protocol is not available by default. To use it, contact your account manager or contact us.

No.

User-Agent blacklist and whitelist

You cannot configure the User-Agent blacklist or whitelist in the ApsaraVideo Live console due to complex configurations and the risk of misoperation.

If you have requirements, you can submit a ticket to request assistance.

Video encryption (Alibaba Cloud proprietary cryptography and DRM encryption)

• Videos can be generated only in the HLS format.

• The encrypted videos can be played only using ApsaraVideo Player and cannot be played by a web client.

No.

Live stream management

• You can call the ForbidLiveStream operation to forbid up to 10,000 live streams. The operation fails if this threshold is exceeded.

• You can call the ForbidLiveStream operation up to 20 times per second per account.

No.

Live stream snapshots

Live stream snapshots can be generated only in the JPG format.

No.

DRM

• You can configure settings only through the console. API calls are not supported.

• This feature is available only in the Shanghai, Singapore, and Indonesia live centers.

• The first time you use the DRM feature for your domain name, you must submit a ticket to enable the feature.

• Supports only ApsaraVideo Player version 5.3.4 and later.

You can submit a ticket.

Domain name management

You must upload a certificate for an accelerated domain name with HTTPS secure acceleration enabled. Because the Tengine service used by ApsaraVideo Live is based on NGINX, only certificates in PEM format that can be read by NGINX are supported.

No.

IP address blacklist and whitelist

The IP address blacklist and whitelist support IPv6 addresses. IPv6 addresses must use uppercase letters. For example, 2001:DB8:0:23:8:XXX:XXXC:417A or 2001:0DB8:0000:XXXX:XXXX:0800:200C:417A. You cannot use shortened IPv6 address representations. For example, 2001:0DB8::XXXX:XXXX:200C:417A is not supported.

No.

Live stream transcoding

• When you configure transcoding templates based on domain name+AppName, a single template cannot contain both standard and Narrowband HD^TM template types.

• For live centers in the China (Beijing), China (Shanghai), and China (Shenzhen) regions, each domain name supports up to 300 concurrent transcoded streams.

• For live centers in other regions, each domain name supports up to 50 concurrent transcoded streams.

• A Narrowband HD^TM transcoding template cannot transcode streams using the H.265 codec.

• You can configure parameters in a multi-bitrate transcoding template as needed.

• For live centers in the China (Beijing), China (Shanghai), China (Shenzhen), and Singapore regions, go to the Quota Center to apply for a quota increase. For more information, see Quota management.

• For live centers in other regions, if you want to increase the quota of concurrent transcoded streams, contact your account manager or submit a ticket.

Live stream recording

• The OSS bucket used to store live stream recordings must reside in the same region as the domain name's live center. Cross-region recording is not supported.

• The VOD transcoding template group must be in the same region as the live center.

• If the ingest bitrate of an ultra-high definition (UHD) 4K or 8K live stream exceeds 25 Mbps and a single TS segment file exceeds 100 MB, the live stream recording will fail.

No.

Live stream pulling

• You cannot pull streams from IPv6 addresses.

• The following limits apply when you configure regular stream pulling:

  • You can add up to four origin URLs.

  • You can use up to 10 templates for regular stream pulling simultaneously.

  • The duration of stream pulling cannot exceed seven days.

• You can call the AddLivePullStreamInfoConfig operation to pull live streams in the RTMP, HTTP, and FLV formats. You can call the operation up to 15 times per second per account.

No.

Stream relay from a live center

A stream can be relayed to up to 200 destination URLs from a live center. If this limit is reached, you cannot add additional stream relay templates.

No.

Push SDK

• Push SDK download: Each version of Push SDK contains two suites. One suite applies only to the ARM architecture and supports debugging on physical devices. The other suite applies to the ARM architecture and simulators, supporting debugging on both physical devices and simulators. If you want to publish your project online, you must use the suite that applies only to the ARM architecture.

• Demo compilation: The demo runs only on physical devices. You cannot run the demo on a virtual machine.

• Stream ingest on mobile devices: When you ingest a local video on a mobile device, the original YUV format for video images is used.
