CDN(内容分发网络)直播加速是一种通过将直播内容分发到多个地理位置的服务器上,使用户能够从最近的服务器获取内容,从而减少延迟和提高观看体验的技术。
CDN直播加速主要涉及以下几个关键概念:
# 创建直播域名
curl -X POST https://cdn.tencentcloudapi.com/instance?Action=CreateLiveDomain \
-H "Authorization: TC3-HMAC-SHA256 Credential=AKIDz8krbsJ5yKBZQpn74WFkmLPx3EXAMPLE/2019-03-26/service/tc3_request, SignedHeaders=content-type;host;x-tc-action;x-tc-timestamp;x-tc-version, Signature=fe5f80f77d5fa3beca078d8ff0ad5bfc785bb29e98162d35b02ee22ddc82cd2b" \
-H "Content-Type: application/json" \
-d '{
"DomainName": "live.example.com",
"SourceType": "push"
}'
# 配置源站信息
curl -X POST https://cdn.tencentcloudapi.com/instance?Action=CreateLiveRecordPlan \
-H "Authorization: TC3-HMAC-SHA256 Credential=AKIDz8krbsJ5yKBZQpn74WFkmLPx3EXAMPLE/2019-03-26/service/tc3_request, SignedHeaders=content-type;host;x-tc-action;x-tc-timestamp;x-tc-version, Signature=fe5f80f77d5fa3beca078d8ff0ad5bfc785bb29e98162d35b02ee22ddc82cd2b" \
-H "Content-Type: application/json" \
-d '{
"DomainName": "live.example.com",
"RecordPlan": {
"PlanName": "DefaultPlan",
"TimeSpan": 3600,
"RecordFormat": "flv",
"OssEndpoint": "oss-cn-hangzhou.aliyuncs.com",
"OssBucket": "live-bucket"
}
}'
通过以上步骤和示例代码,您可以配置CDN直播加速,提升直播内容的传输效率和用户体验。
