Stream Manager 2.0 Restreamer Example – File Restreamer
A File restreamer creates live streams from local files. In a Stream Manager cluster, it makes sense to store video files in shared network storage, mounting the network store in the node image. This way all automatically created nodes have access to the files.
The persist
flag will cause Stream Manager to keep the provision distributed in the event that its origin fails (the SM will find a new node).
File restreamer example
restreamer-file-sm.json
[
{
"provisionGuid": "file1",
"streams": [
{
"streamGuid": "live/stream11",
"abrLevel": 0,
"camParams": {
"properties": {
"action": "create",
"type": "file",
"files": "stream1.flv,stream2.mp4",
"loop": true,
"index": 0
}
}
}
]
}
]
Here we will create a new stream live/strean1
playing back the files stream1.flv
and then stream2.mp4
in a loop.
Create Provision API call:
curl -s -H "Content-Type: application/json" -H "Authorization: Bearer ${JWT}" -X POST --data @restreamer-file-sm.json https://as-test1.example.org/as/v1/streams/provision/nodegroup1
At this point we can List Provisions to find our new provision:
curl -s -H "Authorization: Bearer ${JWT}" https://as-test1.example.org/as/v1/streams/provision/nodegroup1 | json_pp
Now that the Restreamer provision exists, any call to Get Server for Publish must include the restream=true
flag to indicate intent to distribute this provision.
So let’s distribute our provision:
curl -s -H "Content-Type: application/json" https://as-test1.example.org/as/v1/streams/stream/nodegroup1/publish/live/stream1?restream=true
Now the stream should be live, so we should find a new stream live/stream1
when we list all streams:
curl -s -H "Content-Type: application/json" https://as-test1.example.org/as/v1/streams/stream/nodegroup1?aggregate=false | json_pp
It may also be useful to query Get Provision Status — this returns the status of the provision’s streams:
curl -H "Authorization: Bearer ${JWT}" https://as-test1.example.org/as/v1/streams/provision/nodegroup1/file1?status=true | json_pp
Later, when you wish to disable pulling (or after the source stream has ended), delete the provision:
curl -s -H "Content-Type: application/json" -H "Authorization: Bearer ${JWT}" -X DELETE https://as-test1.example.org/as/v1/streams/provision/nodegroup1/file1
