Live Stream Not Working? How to Troubleshoot Live Streaming Issues with Broadcasting
When it comes to live streaming, there are many moving parts. Broadcasters need a workflow for filming the live event, encoding or transcoding the files, delivering the video to users, and allowing playback by viewers. While a modern live streaming platform makes it simple to get started, issues can still pop up.
Even though only 2.6% of live streams fail to start—the biggest problem with live video now—businesses can still lose viewers when streams have issues. If something goes wrong, therefore, broadcasters must respond with error handling best practices for streaming.
That’s why we’ll take a deep dive into how to troubleshoot video streaming issues immediately. Our suggestions follow a typical streaming workflow from video encoding to delivering and playback.
Let’s see what you can do if your live stream is not working correctly. Let’s get right into it so you can troubleshoot your live streaming issues confidently.
Why Isn’t My Live Streaming Working?
First, let’s explore some of the reasons why your live stream might not work as planned. Video streaming issues can occur at any point during the process, so it can be helpful to understand all the steps involved in successful live streaming.
Here are some of the most common reasons for live streaming failures:
1. Using the Wrong Technology
Whether you’re a vlogger doing a simple live stream from your bedroom or a broadcaster doing an elaborate multi-camera stream, you need to use the proper hardware and software.
A lack of preparation is one of the most common reasons for live stream not working. For instance, for live streaming a music event, you need to ensure that everyone musician is properly mic’d up, that the audio is being mixed properly, and that all the cameras are capturing good-quality video.
2. Not Enough Bandwidth
Nothing will drive your viewership down quicker than a live stream with a lot of buffering. Even one short buffering interruption can lower your viewership by nearly 40%. That’s why you need to test your internet connection before you start streaming.
But even with enough bandwidth, your live stream is not working, possibly due to a lack of speed. For example, most Internet service provider plans in the U.S. have an upload speed of 5 Mbps or less. That means you can only live stream video at 720p resolution with a bitrate of 3 Mbps or lower.
3. Audio and Video Not Synced
If your audio and video are out of sync, it can be extremely jarring for viewers. An issue usually causes this stream broadcast unexpected error with the encoder software, but poor internet connections or playback issues can also cause it.
To fix this problem, check your encoder settings and ensure the audio and video bitrates are identical. Simply restarting your encoder software can also fix your video streaming issues. We’ll discuss this process in more detail later. Also, checking your connection and playback devices can help too.
4. Live Streaming Mistakes to Learn From
Mistakes are bound to happen during live broadcasts. Sometimes, you can’t do anything about it. You probably remember this infamous (and hilarious) BBC interview from a few years back. If not, you remember when a power outage disrupted the Super Bowl feed.
Luckily, you can avoid some mistakes and your live stream not working can be avoided.. With enough preparation, you can ensure your live stream goes off without a hitch. Here are some common mistakes broadcasters make and how to avoid them.
5. Not Testing Your Equipment
One common live streaming mistake is not testing your equipment before going live. That can be a costly mistake, especially if you’re using new or rented equipment.
To avoid your live stream not working, always test your equipment before going live.
That way, you can identify and fix any potential issues. The same goes for software. For instance, if you’re using a new live streaming platform like Mslive, it’s important to try it out, learn the ins and outs, and test it with your equipment before going live.
10 Ways to Troubleshoot live streaming Issues
When live streaming, your environment may cause some issues. But as we all know, live streaming technical difficulties can give you a much stronger headache. So, how can you decrease the chances of a live stream not working?
Here are ten ways to troubleshoot live streaming issues:
1. Check Encoder Settings
Double-checking for the correct encoder settings is the best way to ensure a quality live streaming experience.
Most live streams require a hardware or software encoder to convert RAW video files into a format suitable for streaming. Modern encoders, however, have a lot of settings to choose from, and an improper configuration could cause issues.
That’s a common live stream problem, so we always suggest you double-check your encoder settings if your live stream isn’t working correctly.
That’s why at Mslive, we recommend the following settings.
VIDEO CODEC H.264 (x264 may work)
FRAME RATE 25 or 30
KEYFRAME INTERVAL 2 secs (or 2x frame rate)
ENCODING BITRATE Constant (CBR)
AUDIO CODEC AAC
AUDIO BITRATE 128 kbps
AUDIO CHANNELS 2 (Stereo)
AUDIO SAMPLE RATE 48 kHz (48,000 Hz)
These settings are a baseline requirement for a live streaming setup with Mslive. That’s because they’re ideal for ensuring compatibility with the Mslive video platform and a wide range of user devices.
If you don’t see a message that indicates the encoding hardware or software is streaming to primary, there could be an issue with your encoder settings.
First, you’ll want to ensure your live stream encoder is pointed at your streaming server, which delivers the stream to end-users. The encoder’s “Stream Name” and “Stream URL” should match the values provided by your Online Video Platform (OVP).
If the encoder only has a single URL field, you’ll need to use the ‘Backup URL’ under the ‘Other RTMP encoders’ section of Mslive’s encoder software setup page.
If you’re using encoding software that’s not integrated with Mslive, you may also need to enter a login and password during configuration. That information—different from your Mslive account—will also appear on the Mslive encoder setup page.
When multi-bitrate streaming, some encoders require specific names for each stream. However, the requirements may be different, depending on which encoder you’re using. If there still seems to be an issue with your encoder, we recommend trying another option, like OBS Studio.
If an encoder software error occurs while streaming, try the steps above to address the issue.
2. Confirm Bandwidth Availability
Bandwidth measures the data transfer rate, which varies depending on streaming quality, viewers, and more. That means some streams will use more traffic than others, and you’ll need to analyze your bandwidth usage and availability if you’re experiencing live streaming problems.
Every Mslive plan has a limited amount of bandwidth available for streaming. Once you’ve hit the limit, your stream will stop unless you’ve set up overage protection. You can also upgrade your video bandwidth anytime, but it won’t go into effect mid-stream.
That is why it is important to check and ensure you have enough bandwidth before starting your live stream to avoid this streaming issue.
You can check if you’ve hit the limit by viewing the “Upgrade my plan” option within your Mslive account. You can also use our calculator to determine which plan matches your bandwidth requirements based on broadcast frequency, viewers, stream length, and quality.
3. Compare Upload Speed & Bitrate
There needs to be the right ratio between upload speed and bitrate.
The bitrate of a stream is a measurement of the number of bits required to be transmitted per second. Transferring the stream to your OVP needs to be at least as fast as the video stream’s bitrate. Streams with bitrates that exceed bandwidth could suffer from lags, buffering, or outages.
If you’re using adaptive bitrate (ABR) streaming, your total bitrate is the sum of every bitrate you’re streaming simultaneously. We recommend keeping this amount at less than half of your upload speed because network conditions often fluctuate throughout the day.
You can test your upload speed using https://testmy.net/upload. If your steam’s unable to maintain a stable broadcast, you should compare your upload speed to the total bitrate. Then, adjust the bitrates included in your streaming profile to see if it helps.
You can also improve your upload speed by using a wired connection, increasing your internet plan, moving your encoder closer to the router, or limiting the WiFi usage of other devices on the network.To do this, you need to check with your Internet service provider.
You should adjust your total bitrate and upload speed until you find a balance that offers high-quality streams without issues.
Getting the right bitrate set-up will help you avoid quality issues when live streaming.
4. Turn Live Channel On
When broadcasting with Mslive, you’ll need a live channel turned on and configured properly. The channel settings determine the enabled features, viewer restrictions, the video player’s branding, and more.
For example, set up a channel to stream to an HTML5 video player, a low-latency live channel, or a playlist channel for a continuous series of videos. Channels give broadcasters full control over how their video content reaches end-users.
You’ll need to create a live channel within the Mslive dashboard to deliver your encoded video stream to users. Live channels are set to off by default, so a simple mistake is forgetting to enable them before the stream starts.
If the encoder is running, but the video preview is black, make sure you’ve turned the correct live channel on within the Mslive dashboard.
That is an easy streaming problem to fix!
5. Open Streaming Ports & Firewall
Make sure your ports and firewall aren’t blocking the stream.
While most broadcasters can begin streaming immediately, sometimes certain ports are closed by their IT team or a firewall. In addition, your PC or network may sometimes have an integrated firewall that automatically blocks the required ports.
Firewall blocking a video stream is a common issue that we can help you fix!
If there are issues, you should first check if port 1935 is open when streaming troubleshooting. That’s the default port for RTMP and is necessary for your encoder to transfer the stream to Mslive. In addition, the video platform will also attempt to use port 80 or 443 as a backup. That’s why ensuring all three ports remain open is a good idea.
For Mac users, you can check which ports are open by opening the Network Utility. From there, enter your IP address and click scan. After a few moments, you’ll see a list of open TCP ports.
Windows users can check their open ports using the Command Prompt. Type in the command ‘netstart a’ and press enter. Any ports that appear with the LISTENING state are open already.
If one or more of the necessary ports are closed, you’ll likely need to contact your IT team to get them opened manually.
There you have it. If you were wondering, “why won’t my live stream work?” before reading this, we hope you found your answer. Remember, experiencing live streaming problems isn’t anything out of the ordinary.
It may require checking your connection speed, contacting your Internet service provider, or tweaking your encoder settings, but you’ll be able to do it.
Brands should implement a robust and resilient live stream workflow they can rely on in the future. The last thing a broadcaster wants is issues during a live stream that impact the user experience. That said, knowing how to troubleshoot live streams is critical for companies.
