使用场景

场景 1:批量提交素材(自动创建素材组)

不传 group_id,服务端自动创建 AIGC 类型素材组后提交素材。
{
  "group": {
    "name": "virtual-avatar-group",
    "description": "demo group"
  },
  "project_name": "default",
  "asset_type": "Image",
  "assets": [
    {
      "url": "https://example.com/avatar-a.png",
      "name": "avatar-a"
    },
    {
      "url": "https://example.com/avatar-b.png",
      "name": "avatar-b"
    }
  ]
}

场景 2:向已有素材组追加素材

传入 group_id,跳过素材组创建直接提交。
{
  "group_id": "group_xxx",
  "project_name": "default",
  "asset_type": "Image",
  "assets": [
    {
      "url": "https://example.com/avatar-a.png",
      "name": "avatar-a"
    }
  ]
}

场景 3:单素材兼容写法

只提交一个素材时,可直接使用顶层 urlname 字段。
{
  "group_id": "group_xxx",
  "url": "https://example.com/avatar.png",
  "asset_type": "Image",
  "name": "avatar-1"
}

查询审核结果

素材提交后为异步审核任务,使用 获取任务状态 接口查询:
GET /v1/tasks/{id}

全部通过

{
  "code": 200,
  "data": {
    "id": "task_01K...",
    "status": "completed",
    "progress": 100,
    "result": {
      "assets": [
        {
          "asset_id": "asset_a",
          "asset_url": "asset://asset_a",
          "status": "Active"
        },
        {
          "asset_id": "asset_b",
          "asset_url": "asset://asset_b",
          "status": "Active"
        }
      ],
      "usable_assets": [
        {
          "asset_id": "asset_a",
          "asset_url": "asset://asset_a",
          "status": "Active"
        },
        {
          "asset_id": "asset_b",
          "asset_url": "asset://asset_b",
          "status": "Active"
        }
      ],
      "failed_assets": []
    }
  }
}

部分失败

批量提交时,只要有一个素材审核失败,任务状态为 failed。已通过的素材仍可用,出现在 result.usable_assets
{
  "code": 200,
  "data": {
    "id": "task_01K...",
    "status": "failed",
    "progress": 100,
    "result": {
      "assets": [
        {
          "asset_id": "asset_a",
          "asset_url": "asset://asset_a",
          "status": "Active"
        },
        {
          "asset_id": "asset_b",
          "asset_url": "asset://asset_b",
          "status": "Failed"
        }
      ],
      "usable_assets": [
        {
          "asset_id": "asset_a",
          "asset_url": "asset://asset_a",
          "status": "Active"
        }
      ],
      "failed_assets": [
        {
          "asset_id": "asset_b",
          "asset_url": "asset://asset_b",
          "status": "Failed"
        }
      ]
    },
    "error": {
      "code": "task_failed",
      "message": "部分素材审核失败"
    }
  }
}
  • result.usable_assets[].asset_url 可直接用于 Seedance 2.0 视频生成
  • result.failed_assets 中的素材需更换源文件或重新提交
  • 单素材任务也会兼容返回 result.asset_url

审核后使用素材

审核通过后,将 asset://... URL 直接传入 Seedance 2.0 视频生成 接口:
{
  "model": "doubao-seedance-2.0",
  "prompt": "让人物在城市街道自然行走",
  "image_urls": ["asset://asset_a"],
  "duration": 5,
  "resolution": "720p"
}
服务端识别到 asset:// 前缀后,会直接提交官方生成任务,不会再次触发素材审核。
