如何使用 GetHLSStreamingSessionURL 从 kinesis 视频流获取 URL

发布于 2025-01-10 14:55:27 字数 855 浏览 0 评论 0原文

我正在尝试使用 getHLSStreamingSessionURL 获取 URL 以在 kinesis 视频流上查看我的视频。

在邮递员上，我创建了一个对“https://endpoint/getHLSStreamingSessionURL”的 POST 调用

在邮递员上，我收到 200 响应，但响应正文是：

{
    "Output": {
        "__type": "com.amazon.coral.service#UnknownOperationException"
    },
    "Version": "1.0"
}

我希望响应返回 HLS url。

这是我的请求正文：

{
   "ContainerFormat": "FRAGMENTED_MP4",
   "DiscontinuityMode": "ON_DISCONTINUITY",
   "DisplayFragmentTimestamp": "ALWAYS",
   "Expires": 300,
   "HLSFragmentSelector": { 
      "FragmentSelectorType": "PRODUCER_TIMESTAMP",
       "TimestampRange": { 
        "EndTimestamp": 1646055362163,
        "StartTimestamp": 1646055362143
      }
   },
   "PlaybackMode": "ON-DEMAND",
   "StreamName": "DEV_videoStreamTest"
}

任何人都可以建议我的 http 请求出了什么问题并解释这个响应到底意味着什么吗？

I am trying to get a URL to view my video on kinesis video streams with getHLSStreamingSessionURL.

On postman I have created a POST call to 'https://endpoint/getHLSStreamingSessionURL

On postman I get a 200 response but the response body is :

{
    "Output": {
        "__type": "com.amazon.coral.service#UnknownOperationException"
    },
    "Version": "1.0"
}

I expect the response to return a HLS url.

And here is my request body:

{
   "ContainerFormat": "FRAGMENTED_MP4",
   "DiscontinuityMode": "ON_DISCONTINUITY",
   "DisplayFragmentTimestamp": "ALWAYS",
   "Expires": 300,
   "HLSFragmentSelector": { 
      "FragmentSelectorType": "PRODUCER_TIMESTAMP",
       "TimestampRange": { 
        "EndTimestamp": 1646055362163,
        "StartTimestamp": 1646055362143
      }
   },
   "PlaybackMode": "ON-DEMAND",
   "StreamName": "DEV_videoStreamTest"
}

Can anyone suggest what is wrong with my http request and explain what exactly this response means?

我发现这有点复杂，但你需要打电话给
首先 GetDataEndpoint 以获得正确的 API 端点 URL调用获取HLSStreamingSessionURL。

AWS Github 上有一个很棒的完整示例，您可以使用它来尝试所有参数：
amazon-kinesis-video-streams-media-viewer

但简而言之，调用

https://kinesisvideo.<region>.amazonaws.com/getDataEndpoint

返回类似这样的内容：

{ "DataEndpoint": "https://b-1234xyz.kinesisvideo.us-west-2.amazonaws.com" }

然后调用 getHLSStreamingSessionURL 替换您的基本 url：

https://b-1234xyz.kinesisvideo.us-west-2.amazonaws.com/getHLSStreamingSessionURL

我正在使用 boto3，所以这是我的简化示例 Python：

import boto3

# Get the API URL
kinesis_client = boto3.client("kinesisvideo")
response = kinesis_client.get_data_endpoint(
    StreamName=stream_name,
    APIName="GET_HLS_STREAMING_SESSION_URL"
)
endpoint_url = response.get("DataEndpoint")

# Get the Stream URL
kinesis_client = boto3.client(
    "kinesis-video-archived-media",
    endpoint_url=endpoint_url
)
response = kinesis_client.get_hls_streaming_session_url(
    StreamName=stream_name,
    ...
)

I found this a bit convoluted, but you need to make a call to
GetDataEndpoint first in order to get the correct API endpoint url to make the call to GetHLSStreamingSessionURL.

There's a great full example on the AWS Github, and you can use that to try out all the parameters:
amazon-kinesis-video-streams-media-viewer

But in short, the call to

https://kinesisvideo.<region>.amazonaws.com/getDataEndpoint

returns something like this:

{ "DataEndpoint": "https://b-1234xyz.kinesisvideo.us-west-2.amazonaws.com" }

then you make the call to getHLSStreamingSessionURL replacing your base url:

https://b-1234xyz.kinesisvideo.us-west-2.amazonaws.com/getHLSStreamingSessionURL

I'm using boto3, so here's my simplified example in python:

import boto3

# Get the API URL
kinesis_client = boto3.client("kinesisvideo")
response = kinesis_client.get_data_endpoint(
    StreamName=stream_name,
    APIName="GET_HLS_STREAMING_SESSION_URL"
)
endpoint_url = response.get("DataEndpoint")

# Get the Stream URL
kinesis_client = boto3.client(
    "kinesis-video-archived-media",
    endpoint_url=endpoint_url
)
response = kinesis_client.get_hls_streaming_session_url(
    StreamName=stream_name,
    ...
)
