    To learn about the licenses required to use different editions of the SDK, please see SDK and license.

    Downloading the SDK

    We provide three editions of the MLVB SDK currently: LiteAV_Smart, Professional, and Enterprise. You can unlock their live streaming features with MLVB SDK licenses.

    Edition Description
    LiteAV_Smart With a LiteAV_Smart license, you can use features including publishing, playback, and basic beauty filters (skin brightening and smoothing).
    Professional The Professional edition integrates multiple audio/video services of Tencent Cloud. Other than the support for LEB, it offers the same MLVB features as LiteAV_Smart, but it is free of the duplicate symbol issue that may arise if you integrate multiple audio/video SDKs. You can use the MLVB features of the Professional edition with a LiteAV_Smart license, but to use the features of other Tencent Cloud services, you need to activate the services first.

    For details on the features supported by different SDK editions, please see Features.
