在視頻制作中,可以將含有關鍵信息的視頻起始、結尾內容以畫中畫的形式拼接嵌入到正片視頻中,稱為開板、尾板。本文為您介紹媒體處理中Python SDK設置開板和尾板的示例代碼。
示例代碼
import os
import json
from urllib.parse import quote
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException

# region_id 為調用的服務地域ID,支持的地域參考 http://bestwisewords.com/document_detail/43248.html
client = AcsClient(region_id = 'cn-shanghai', credential = credentials)

request = SubmitJobsRequest()
request.set_accept_format('json')
# Input參數結構 object需要進行url編碼
job_input = {'Location': oss_location,
'Bucket': oss_bucket,
'Object': quote(head_object) }
request.set_Input(json.dumps(job_input))
# Output參數結構
output = {'OutputObject': quote(oss_output_object)}
output['TemplateId'] = template_id
# Output->OpeningList開板參數結構

'Width': 640,
'Start': 2}
output['OpeningList'] = [opening_video]
# Output->TailSlateList尾板參數結構
tailslate_video = {'TailUrl': 'http://%s.%s.aliyuncs.com/%s'%(oss_bucket, oss_location, quote(tail_object)),
'Width': 640,
'BlendDuration': 3,
'BgColor': 'Black'}
output['TailSlateList'] = [tailslate_video]
# Outputs輸出參數結構
outputs = [output]
request.set_Outputs(json.dumps(outputs))
request.set_OutputBucket(oss_bucket)

request.set_PipelineId(pipeline_id)
response_str = client.do_action_with_exception(request)
response = json.loads(response_str)
# 輸出打印
print(str(response, encoding='utf-8'))
