Solve a Streaming Radio problem

This guide makes it possible to make a diagnosis of your Streaming Radio in order to find the origin of possible problems, causes of disconnection, etc.

Preamble

• If you are broadcasting your FM radio, check the proper operation of the acquisition card.
• If you are broadcasting a Webradio, make sure that your broadcast software works properly.
  • Pay attention to the CPU charge on your computer: make sure that it is not saturation, making sure you have enough memory if you do operations in addition to an AAC feed encoding, which is very memory-intensive.
• It may be your Fibre/ADSL line that can no longer track the data sent to the server.
  • You must have an upload rate (so up) at least equivalent to the total of the streams sent to the server (e.g. a radio that sends a stream in 128kbs + a stream in 48kbs, that gives 130 + 50 = 180kbit/s at least).
  • Generally, radios dedicate a line exclusively to the broadcast of audio streams in order to avoid any saturation of bandwidth in the event of simultaneous sending, such as sending a large e-mail with an attachment. This precaution ensures that the upload does not monopolize bandwidth, which could result in interruptions in the broadcast of audio streams during listening.
  • Your ISP can also generate a cut-off on the line, even a tiny one, but it will have the effect of shutting down the radio stream.
• If your encoder is configured to send metadatatas to servers via a text file hosted by another provider, and the latter undergoes disruptions, the flow can also be disturbed!

Analyze recent statistics

The statistics allow you to view possible interruptions of flows. To access this information:

1. Click here in order to access the management of your product on the Manager Infomaniak (Need help?).
2. Click directly on the nameallocated to the product concerned.
3. Click on Statistics in the left side menu:
   
   • The statistics are detailed on this other guide.

Check the proper functioning of the elements

The page of radio diagnosis allows you to access various information. To access these diagnoses:

1. Click here in order to access the management of your product on the Manager Infomaniak (Need help?).
2. Click directly on the nameallocated to the product concerned.
3. Click on the name of the audio stream concerned:
   
4. Click on Diagnosis in the left side menu:
   
   1. The tab Network and flow allows for test connection between your server and Infomaniak infrastructures.
   2. The tab Encoders displays a history of encoder connections to analyze whether the flows were operational.
   3. The tab Servers provide information on the general state of the network infrastructure in order to verify the proper functioning of the reception and broadcasting servers.
   4. The tab Stability of buffer is detailed on this other guide.

Note that in the case of a general shutdown of broadcast flows, the Infomaniak teams are notified and intervene immediately.
