配额用于指定您可以使用的可计数共享资源的数量。配额由 Live Stream API 等 Google Cloud 服务定义。
系统限制是无法更改的固定值。
Google Cloud 使用配额来帮助确保公平性并减少资源使用和可用性的激增。配额用于限制您的 Google Cloud 项目可使用的Google Cloud 资源的数量。配额适用于一系列资源类型，包括硬件、软件和网络组件。例如，配额可以限制对某项服务的 API 调用次数、您的项目并发使用的负载均衡器数量或者您可以创建的项目数量。配额可以防止服务过载，从而保护Google Cloud 用户社区。配额还可以帮助您管理自己的 Google Cloud 资源。

Quotas are defined by Google Cloud services such as Live Stream API.\n- *System limits* are fixed values that cannot be changed.\n\nGoogle Cloud uses quotas to help ensure fairness and reduce\nspikes in resource use and availability. A quota restricts how much of a\nGoogle Cloud resource your Google Cloud project can use. Quotas\napply to a range of resource types, including hardware, software, and network\ncomponents. For example, quotas can restrict the number of API calls to a\nservice, the number of load balancers used concurrently by your project, or the\nnumber of projects that you can create. Quotas protect the community of\nGoogle Cloud users by preventing the overloading of services. Quotas also\nhelp you to manage your own Google Cloud resources.\n\nThe Cloud Quotas system does the following:\n\n- Monitors your consumption of Google Cloud products and services\n- Restricts your consumption of those resources\n- Provides a way to [request changes to the quota value](/docs/quotas/help/request_increase) and [automate quota adjustments](/docs/quotas/quota-adjuster)\n\nIn most cases, when you attempt to consume more of a resource than its quota\nallows, the system blocks access to the resource, and the task that\nyou're trying to perform fails.\n\nQuotas generally apply at the Google Cloud project\nlevel. Your use of a resource in one project doesn't affect\nyour available quota in another project. Within a Google Cloud project, quotas\nare shared across all applications and IP addresses.\n\n\nThere are also *system limits* on Live Stream API resources.\nSystem limits can't be changed.\n\nGeneral limits\n--------------\n\n- Live stream sessions last for 24 hours after you start a channel. After 24\n hours in any [`StreamingState`](/livestream/docs/reference/rest/v1/projects.locations.channels#streamingstate) other than `STOPPED` or `STOPPING`, the channel may be restarted.\n\n- A mux stream with a `ts` container must contain exactly one audio stream and up\n to one video stream.\n\n- Only HLS manifests can contain mux streams with the `ts` container. Manifests\n cannot contain a mixture of `ts` and `fmp4` mux streams.\n\n- Input with H265 codec is only supported for SRT inputs.\n\nAllocation quotas\n-----------------\n\nThe following regional quotas don't reset over time and instead are released\nwhen you release the resource:\n\n^1^Channel quota applies to running channels. You can only run up to\n10 channels at a time per region.\n\nRate quotas\n-----------\n\nThe following quotas apply to Live Stream API requests:\n\nThese quotas apply to each Google Cloud project and are shared across all\napplications and IP addresses using that project.\n\nInput limits\n------------\n\nInput streams must follow the limits provided below:\n\nOutput limits\n-------------\n\nPer-channel resource limits\n---------------------------\n\nThe following limits apply to each individual channel:\n\n^1^ Once the limit is reached, you must delete the oldest events to make\nroom for new events.\n\nQuota increases\n---------------\n\nIf you want to increase any of your quotas for Live Stream API, you can\nuse the Google Cloud console to request a quota increase. For more information, see\n[Request a quota adjustment](/docs/quotas/help/request_increase)."]]
