How To Monitor and Troubleshoot Your Live Stream

This post addresses potential obstacles you might encounter as a broadcaster and a route to avoiding them with active monitoring, stream diagnostics, and a support team behind it all. It's part of our series on BoxCast Features.

As a broadcaster, ensuring your viewers have a positive experience is absolutely critical. A low quality or disrupted stream can be a poor mark on your organization and brand.

High quality live streaming can be easy. However, there are still external obstacles that can prevent a perfect broadcast. The number one offender is your network connection.

In order to troubleshoot issues as quickly as possible, we always recommend choosing a live streaming provider that offers direct customer support.

A customer support team paired with a platform that monitors and diagnoses your stream is the best way to ensure a great broadcast every time.

What Can Happen to Your Stream

If you have an end-to-end streaming platform, there are two potential points of transfer during your stream.

The first is the capture connection, in which your video data transfers (in packets) from your video camera or video production equipment via an encoder.

The second is the delivery connection, where the stream goes from your platform to other simulcast destinations (like Facebook Live or YouTube Live).

Capture and Delivery-1

Capture Connection

A good internet connection is crucial for the capture connection. Specifically, you must have good upload bandwidth.

Even if you think you're receiving the necessary bandwidth for your stream because of what Internet Service Provider says it's providing, it's always worthwhile to test on your own.

A poor connection between the video capture point and the streaming platform will result in packet loss. Packet loss, although fine in small amounts, will result in dropped frames and blocky pictures if left untamed.

Common sources of capture connection trouble include:

  • Poor upload speed
  • Fluctuating bitrate
  • Bad ethernet cable
  • Bad router
  • Bad ethernet switch

Delivery Connection

The delivery connection deals with the transfer of live video between your live streaming provider and external simulcast destinations. With BoxCast, those destinations include Facebook Live, YouTube Live, and Twitter within the platform, and any other destination via RTMP.

Note, when you send your stream through your live streaming platform's own CDN to its player, there is no external delivery connection.

The delivery connection can go awry if your external destinations fail to connect to your streaming platform. The ways in which the destinations connect can vary.

Common sources of delivery connection failure include:

  • Disconnected destination account
  • Destination algorithm observes potential copyright infringement

Here are resources that cover each of those streaming destinations:


How To Combat Potential Live Stream Issues

A comprehensive approach to troubleshooting your live stream includes proactive broadcast monitoring, diagnostics to better understand your stream health, and a support team to help you interpret what's going on.

This approach also includes the ability observe your stream from anywhere. Not all broadcasters are on location. If your equipment is in a side room or if you are in a completely different place, you still need access to what's going on with your broadcast.

At BoxCast, we've thought carefully about how all of these elements can work together to proactively give you the confidence you need to create a great stream.

All of the following elements of monitoring and diagnostics are available on the BoxCast Dashboard, which can be accessed from anywhere.

Don't have a computer on you? They are even available for on the BoxCast Broadcaster App for iOS.


Broadcast Monitoring

Broadcast Monitoring in your BoxCast Dashboard gives you peace of mind that the capture and delivery connections are in place.

Source + Destination Statuses

Right beside the video player with your live broadcast you will see indicators for source and destinations. When the green indicator appears beside your proper source and simulcast destinations, you can rest easy knowing that everything is up and working correctly. When the red light appears, there are issues connecting.


Note, the destinations will not appear if you have not chosen to simulcast. Why? If you are streaming only to your website, BoxCast.tv, and/or Roku, AppleTV, Amazon Fire TV, or Chromecast your streaming destinations are all within the BoxCast CDN. In this case, there's no delivery connection to an external platform, so it's one less thing to worry about.

If you click on the source box, you reveal details about the particular source you are using for the broadcast including the status, video source connection type (HDMI, SDI, or RTMP) , WAN IP Address, video input, and streaming profile.


Broadcast Status Bar

If something is not properly connected, you will receive status alerts on your broadcast page to let you know what's disconnected.


If everything is connected and your broadcast is live, the broadcast status bar will let you know that all is well.



Stream Diagnostics

While Broadcast Monitoring provides indicators that everything is connected or that something may be amiss, Stream Diagnostics allows broadcasters to dive a little bit deeper into the details.

On the broadcast page in the Dashboard, you can view stream health alerts, bitrate and frame rate data, stream health graphs, and a stream health rating.

After the stream ends, broadcasters receive a stream health rating with tips on how to improve future broadcasts.



Stream Health Alerts

In the Diagnostics tab on the broadcast page, broadcasters can see alerts on their stream health. Unlike the status bar that lets you know if the stream is live and external connections are functioning, these alerts give you a more detailed summary of stream health warnings.

The platform intelligently prescribes specific alerting conditions based on which encoder you are using and other factors such as your target streaming resolution (e.g. you don't need as high of a bitrate for a 720p stream as you do for a 1080p60). 

Below is a quick explanation of what the alerts mean:

  • Waiting to receive data: Our servers have not yet processed any data from your BoxCaster or encoder. Make sure everything is plugged in and ready to go.
  • Bitrate too low: Some data is being received, but it is not at a high enough bitrate for your selected profile. This is something you will not have to worry about if you are using a BoxCaster, but if you are using RTMP, you may need to update your encoder settings.
  • Frame rate too low: The frame rate of the broadcast has fallen too low.  This may often accompany a "bitrate too low" message if your Internet is experiencing packet loss. 
  • Frame rate too high: The frame rate of your broadcast is too high.  If you are trying to stream at 60fps, you must have the Pro Feature Bundle with high frame rate support, otherwise it will drop frames to bring it down to 30fps.
  • Bitrate too high: The detected broadcast bitrate is too high for the selected profile. This can lead to other issues such as transcode delays. We provide you the proper RTMP Encoder setting in the dashboard for you to use to prevent this.
  • Transcode delayed: We have detected that the cloud transcoding is falling behind. This issue is often caused by misconfigured RTMP encoders. It can lead to buffering for viewers. Please refer to the RTMP Encoder Settings on the dashboard for the proper bitrates and profiles.  Depending on the specific encoder, you may need to do some testing to find the best settings for your quality expectations.
  • Discontinuity detected: A "discontinuity" in the stream was detected.  This is most often in combination with a streaming interruption, but might also be triggered if your encoding parameters or audio/video timestamps change.
  • Streaming interrupted: No data is being received by our servers, and viewers are likely to experience buffering.  Ensure you have a sufficient internet connection to stream (and some extra buffer) to prevent this from happening in the future. 
  • Poor network health: The server has detected that the stream is not a high enough quality for the selected video resolution. This can be due to too low of upload bandwidth, packet loss, or other network characteristics that keep the bitrate lower than desired.

Bitrate and Frame Rate Summary

In the same summary view, broadcasters can see a quick summary of the bitrate as well as the frame rate of the stream.


Stream Health Graphs

By toggling on the Show Graphs box in the summary view, broadcasters can see minute-by minute analysis on:

  • Broadcast Bitrate (Kbps, Mbps)
  • Broadcast Frame Rate (FPS)
  • Simulcast (FPS)
  • Packet Loss

These graphs reveal insight into the fluctuations in connectivity throughout the duration of the broadcast.


Stream Health Rating

After a broadcast ends, a star rating (5 star scale) is assigned, based on several factors. Here's a guide to the ratings:

  • 5 stars: The broadcast quality was great! The bitrates and frame rates matched what we expected, and there were no alerts generated during the entire broadcast.
  • 4.5 stars: Good job! No critical alerts were generated.
  • 4 stars: There may have been some alerts, but the overall average bitrates and frame rates were good.
  • 1, 2, or 3 stars: The detected average bitrates and/or frame rates were lower than preferred for the target video resolution in your broadcast. You might need to work with your Internet Service Provider to improve your Internet connection if this continues to be a problem.

Additional tips and recommendations may be given directly in the dashboard to help you understand how to resolve certain detected alert conditions.
