amazon-web-services - 使用 aws chime 增加 createMediaCapturePipeline 的视频捕获时间

Question

我正在使用 chime sdk 创建 createMediaCapturePipeline 来录制 chime 会议，它工作正常，但它只会在 5 秒内捕获视频帧。如何增加拍摄视频的时间。下面是我的代码：

            var region = 'us-east-1';
            const chime = new AWS.Chime({ region: region });
            let meetingId = input.MeetingId
            const captureRequest = {
                "SourceType": "ChimeSdkMeeting",
                "SourceArn": "arn:aws:chime::"+aws_account_id+":meeting:" + meetingId,
                "SinkType": "S3Bucket",
                "SinkArn": "arn:aws:s3:::"+my_bucket+" + meetingId
            }
            const captureInfo = await chime.createMediaCapturePipeline(captureRequest).promise();
