This little guide is here to help you to troubleshoot using the tools we provide.
DO NOT PANIC: Technical problems arrive and panicking won’t help. You must remain calm to troubleshoot effectively.
The troubles can come from:
- Your Internet connection.
- The network lock.
- A wrong encoder configuration.
I can't retrieve my live feed on LiveU Studio
- Check that you're in the Testing or Publishing phase on LiveU Studio.
-
Check if the feed is correctly sent:
- Download VLC.
- In the LiveU Studio Production section (1).
- Click on the problematic RTMP input (2).
- Click on View (3).
- Copy the provided URL (4).

- Paste this URL in VLC (Open network stream).
⇒ Do you receive the stream in VLC?
Yes ⇒ The feed should be visible in the LiveU Studio, if this is not the case please contact us via chat or mail.
No ⇒ This indicates you have a local problem (internet connection/network lock/bad encoder configuration).
Please check :
- Your internet connection, as well as the RTMP URL, defined in the encoder.
- Check that your encoder is sending the feed and that the encoding profile is as follows :
- Video profile: H264 or H265
- Audio profile: AAC, 48Khz
- Key Frame interval: 2 sec
- Bitrate recommendations

If the problem persists don't hesitate to contact us by chat.
Viewers are complaining about the stream
Check the stream on VLC
- In the LiveU Studio Publish tab (1), click on the RTMP recording button (2) and copy the provided URL.
- Paste this URL in VLC (Open network stream).

You can now look at the quality we are currently delivering.
⇒ Is the quality of the live feed as expected?
Yes ⇒ It's a local problem (on the viewer side) or a problem on the server of the social network you are sending to, there is nothing to do.
No ⇒ go to the next step and let's check the received feed (input).

Bitrate variations
Too many variations imply an issue with the live source you are ingesting.

- Profiles you might get:


What to do in case of a problem with the feed received by LiveU Studio?
- Contact your network technician.
- If the bandwidth is used by other devices -> setup a QoS on the device emitting the feed.
- Use a second internet connection to publish a backup feed.
- If the minimum local delay is:
- Less or equal to 2s -> set the LU Studio input delay value to auto.
- Greater than 2s -> increase the latency (put the same delay value in your encoder than in LiveU Studio).
- Your bandwidth is too low/unstable:
- In case of slow down/fps problem in 1080p 60 fps:
- Reduce the number of layers and/or sources to the minimum (you can use hotkeys to optimize the number of input/layers).
