二、通过Python-SDK调用视频理解-生成视频封面

1、pip install

pip install aliyun-python-sdk-videorecog==1.0.4

2、创建GenerateVideoCover

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.auth.credentials import AccessKeyCredential
from aliyunsdkvideorecog.request.v20200320.GenerateVideoCoverRequest import GenerateVideoCoverRequest
credentials = AccessKeyCredential('accesskey', 'accesskeysecret')
client = AcsClient(region_id='cn-shanghai', credential=credentials)
request = GenerateVideoCoverRequest()
request.set_accept_format('json')
request.set_VideoUrl("url")
request.set_IsGif(False)
response = client.do_action_with_exception(request)
print(str(response, encoding='utf-8'))

3、返回异步任务请求ID

{
 "RequestId": "02***E7B-E496-58C0-AC31-B6***9B"
}

4、查询异步任务结果

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.auth.credentials import AccessKeyCredential
from aliyunsdkvideorecog.request.v20200320.GetAsyncJobResultRequest import GetAsyncJobResultRequest
credentials = AccessKeyCredential('accesskey', 'accesskeysecret')
client = AcsClient(region_id='cn-shanghai', credential=credentials)
request = GetAsyncJobResultRequest()
request.set_accept_format('json')
request.set_JobId("02***E7B-E496-58C0-AC31-B6***9B")
response = client.do_action_with_exception(request)
print(str(response, encoding='utf-8'))

5、获取异步结果数据返回

{
 "RequestId": "3C****AA-44FE-5978-B950-05131914018A",
 "Data": {
 "Status": "PROCESS_SUCCESS",
 "JobId": "02***E7B-E496-58C0-AC31-B6***9B",
 "Result": "{\"Outputs\":[{\"ImageURL\":\"http://vibktp**********8Cw%3D\",\"Confifidence\":8.933435588336971}, 
{\"ImageURL\":\"http://vibkt

 }
}
