Start recording - "Start is not allowed!"

Wowza Video (Formerly Streaming Cloud)

After I started a transcoder, I tried to start recording via

https://api.cloud.wowza.com/api/v1.5/transcoders/{id}/start_recording

but response was

{
  "meta": {
    "status": 422,
    "code": "ERR-422-InvalidStateChange",
    "title": "Invalid State Change Error",
    "message": "The request couldn't be processed. Start is not allowed!",
    "description": ""
  },
  "request_id": "e9a083ee8d056a12c4ae37b06c52fcde",
  "request_timestamp": "2020-07-10T10:54:48.017Z"
}

I tried with both transcoder_type: passthrough | transcoded but no luck…

Also, createTranscoder api has recording: boolean field, but documentation says

recording

boolean

This parameter is sunset and no longer available.

and it seems simply ignored (even if I specified recording: true, no recordings are started when I started the transcoder)

I confirmed that no recording is running via

[https://api.cloud.wowza.com/api/v1.5/transcoders/{id}/recordings](https://api.cloud.wowza.com/api/v1.5/transcoders/%7bid%7d/recordings)

Can someone help me to start recording?

Self solved, I just need to specify

properties: [
  {
    "section": "recording",
    "key": "mp4",
    "value": true
  }
]

on creating transcoder, then no need to manually start.

Also, recording will be created after the transcoder stops. So don’t worry if you can’t find any recordings while transcoder is running.
