    ApsaraVideo Live：AddCustomLiveStreamTranscode

    更新時間：Oct 29, 2024

    Adds a custom transcoding configuration.

    This operation supports the following types of custom transcoding templates:

    • h264: custom H.264 standard transcoding.
    • h264-nbhd: custom H.264 Narrowband HD™ transcoding.
    • h265: custom H.265 standard transcoding.
    • h265-nbhd: custom H.265 Narrowband HD™ transcoding.
    • audio: audio-only transcoding.

    QPS limit

    You can call this operation up to 6,000 times per minute 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.
