Quotas and limits

This document lists the quotas and system limits that apply to Live Stream API.

Quotas specify the amount of a countable, shared resource that you can use. Quotas are defined by Google Cloud services such as Live Stream API.
System limits are fixed values that cannot be changed.

Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.

The Cloud Quotas system does the following:

Monitors your consumption of Google Cloud products and services
Restricts your consumption of those resources
Provides a way to request changes to the quota value

In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.

Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.

There are also system limits on Live Stream API resources. System limits can't be changed.

General limits

Live stream sessions last for 24 hours after you start a channel. After 24 hours in any StreamingState other than STOPPED or STOPPING, the channel may be restarted.
A mux stream with a ts container must contain exactly one audio stream and up to one video stream.
Only HLS manifests can contain mux streams with the ts container. Manifests cannot contain a mixture of ts and fmp4 mux streams.

Allocation quotas

The following regional quotas don't reset over time and instead are released when you release the resource:

Quotas per region	Value
Channels	10¹
Inputs	20
HD output streams	20
SD output streams	40
Assets	10

¹Channel quota applies to running channels. You can only run up to 10 channels at a time per region.

Request quotas

The following quotas apply to Live Stream API requests:

Request quota	Value
API requests per minute	6000
Operation requests per minute per region	1200
Get requests per minute per region	1200
List requests per minute per region	300
Mutation requests per minute per region	300

These quotas apply to each Google Cloud project and are shared across all applications and IP addresses using that project.

Input limits

Input streams must follow the limits provided below:

Tier	Resolution	Bitrate	FPS
SD	<720p	<=6 Mbps	<=60
HD	<=1080p	<=25 Mbps	<=60

Output limits

Tier	Resolution	Bitrate	FPS
SD	<720p	<=3 Mbps	<=60
HD	<=1080p	<=15 Mbps	<=60

Per-channel resource limits

The following limits apply to each individual channel:

Resource per channel	Value
Events¹	1000
Input attachments	6
Manifests	10
HD video output streams	3
Total video output streams	10
Audio output streams	20
Sprite sheet settings	3

¹ Once the limit is reached, you must delete the oldest events to make room for new events.

Quota increases

If you want to increase any of your quotas for Live Stream API, you can use the Google Cloud console to request a quota increase. For details, see Requesting higher quota.
