DescribeLiveDomainFrameRateAndBitRateData -

Usage notes

You can call this operation to query the real-time bitrates and frame rates of live streams, which helps you evaluate the stream ingest quality. A delay exists in data collection and statistics. We recommend that you query the data of more than 5 minutes ago.

Note Use this operation to replace the deprecated DescribeLiveStreamsFrameRateAndBitRateData operation.

QPS limit

You can call this operation up to 100 times per second per account. Requests that exceed this limit are dropped and you will experience service interruptions. We recommend that you take note of this limit when you call this operation. For more information, see QPS limits.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
