从S3存储桶流式传输视频 [英] Streaming videos from S3 bucket
问题描述
我正在使用Node.js服务器进行视频流传输.我已将Amazon S3存储桶用作视频存储.当nodejs在Amazon EC2实例中运行时.为了响应客户端的请求流式传输特定的视频文件，需要先将文件从S3存储桶下载到EC2实例(nodejs服务器)，这是一个耗时的过程，客户端必须在第一个客户端之前等待几秒钟.视频片段从nodejs发送到客户端.我正在寻找一种删除下载时间间隔的方法. 我的问题是:
I am working on video streaming with nodejs server. I have used Amazon S3 bucket as video storage. While nodejs is running in an Amazon EC2 instance. In order to stream a specific video file in response to a client's request, the file needs to be downloaded from S3 bucket to EC2 instance (nodejs server) first, which is a time consuming process and client has to wait for several seconds before the first video segment is sent from nodejs to client. I am looking for a way to remove the downloading time interval. My questions are :
1#是否可以直接从S3存储桶中流式传输?
1# Is there a way to directly stream from S3 bucket?
或
2#S3存储是否允许获取存储文件的小块而不是下载整个文件?
2# Does S3 storage allows to get small chunks of stored file instead of downloading the whole file?
注意:视频流应该由iOS视频播放器使用. 我是视频流和S3存储的新手.
Note : Video stream is supposed to be used by iOS video players. I am a newbie to video streaming and S3 storage.
在这种情况下，建议我最好的解决方案.
Kindly suggest me the best possible solution in this scenario.
