Connection Between Software and the Event Manager

The connection is not working.

  • The first thing to check is that you have the correct URL in the settings of your streaming software. If the url is not correct, the software cannot transmit your video's information to the event manager to broadcast to your customers.

If you are using OBS Studio, copy the URL under the Server line in the RTMP section.
Also make sure you have written stream under the key field of OBS.

If you are using Larix Broadcaster, copy the URL from the SRT section.

  • Do you have a good internet connection? Check out our full article on this essential element of live video.

Although the recommended upload speed is a minimum of 10 Mbits/s, our team's tests seem to conclude that you will probably encounter streaming problems if your upload speed is less than 15 Mbits/s.

It is also important to note that the speed varies depending on your network's traffic. A speed test carried out at 1 p.m. could give a very different result than one carried out at 7 p.m., a time when a large number of people use the Internet.

Other users on your internet connection? Be aware that if someone is listening to videos, taking part in a conference, or playing an online video game on the same connection as you, it greatly affects your ability to stream live video.

  • Do you allow enough time to establish the connection? It may take several seconds after you start your video on your device for it to communicate with the event manager and establish a connection with the servers used for live streaming. Our team encountered delays of up to 45 seconds before the connection was made.

If the connection is not established the first time, do not hesitate to stop streaming on your device, wait a few seconds and start again.

  • s your streaming device, whether it's a mobile device or a computer, powerful enough to support streaming?

Your device may not be powerful enough for live video. Make sure your software and capture device are set to 720p and 30 fps. If they are not, your device is attempting to produce a higher resolution than necessary and reduces the performance of the software unnecessarily.

OBS Studio

  1. In Settings, click Video.
  2. Change your resolutions (Base (Canvas) Resolution & Output (Scaled) Resolution ) for 1280x720
  3. Change your Common FPS Value to 30.
  4. In the Output tab, make sure that the Video Bitrate is 4000 and that the Encoder is x264

If these changes still don't help, you can investigate online if the problem has been resolved by someone else.

However, your computer or mobile device may not be powerful enough for streaming. How do you know? Does the broadcast of your video cause your processor (CPU) activity rate to rise above 70%? Does your device get hot (like it's burning) when you stream the video? These are signs that your device is not powerful enough.

👉 If you are using OBS Studio, this comprehensive article can help you determine and resolve your problem.



Image lag

Most of the time, if your video suffers from lag, there are two reasons: Your internet connection is too weak or your streaming device is not powerful enough. See the solutions above. ☝️

Another solution would be to change the video bit rate from 4000 Kpbs to 2500Kpbs.

Pre-recorded video, how big is your file?

If your file is too large, you will not be able to stream the desired video quality. When it comes to live streaming, bigger does not equal better customer experience. Try to shrinking your file.


No image appears on OBS

  • Make sure your video capture device is in the Sources section of OBS Studio. If missing, click the + under Sources (next to Controls in the lower section)

Select Video Capture Device.

Once the device is named, you can select it from the drop-down menu under Device.

  • Make sure, also, that the eye icon next to the source name (signifying on-screen visibility) is white and not pale gray.



Loop sound

  1. Is it possible that your audio device also picks up an already open window with your live video? If yes, simply mute the sound from this window.
  2. Is there any other way that your video captures its own sound? Is someone watching your video inside the sound capture area?


No sound (OBS studio)

  • Make sure your audio capture device is in the Sources section of OBS Studio. If it is not, click the + under Sources (next to Controls in the lower section)

Select Audio Input Capture.

Once the device is named, you can select it from the drop-down menu under Device.


No sound (Larix Broadcaster)

  • Have you given permission to the Larix Braodcaster application to use your microphone? Without this authorization, the application does not have access to the elements necessary for sound recording. Go to the Settings of your mobile device and accept the authorizations requested by the application.
