Your stream source is not connected

If you have a message stating that your feed is not connected:


  • Check that you have entered the correct URL and streaming key in your encoder (e.g. OBS). A bad copy and paste or a forgotten saving of these parameters is sometimes the reason of the problem.


  • Check your encoder settings. 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)
SCANNING Progressive
AUDIO SAMPLE RATE 48 kHz (48,000 Hz)

Check the bitrate (bottom right for OBS), if it is constant (or at 0 kb/s) there is a problem.


  • Stop the stream on OBS and restart it. Disconnect from the OKAST Back-Office and come back to the live page. If this doesn’t work, try to restart OBS.


  • Check the OBS version, we recommend downloading the latest version of the software, at least version 26.0. If it still doesn’t work, try with another encoder.


  • Your uplink is not powerful enough to send the stream to our streaming server. To check, go for example to and note the upload rate information. Depending on the quality of the content you want to live stream, here are our minimum upload speed recommendations:
Résolution Fps Bitrate Débit Montant Minimum
720p 30fps 3000 kbps 3,7 Mbps
720P 60fps 4500 kbps 5,6 Mbps
1080p 30fps 5000 kbps 5,6 Mbps
1080p 60fps 6000 kbps 7,5 Mbps

Warning: on shared connections, this theoretical throughput can be shared between several users. So we recommend to have at least 3 times the minimum amount of bandwidth in the bandwidth test.

Poor quality image

  • The movements are not fluid: it is certainly due to a frame rate too low (less than 25fps). Try to increase to 50 or 60 fps (especially if it’s a sport video). In any case, we recommend doing a maximum of tests beforehand to find the perfect configuration.  Warning: if you change the setting on your camera or capture device, change it on your encoder as well (and vice versa).


  • The image is jerky or barely appears: it may be a problem with your internet connection or your encoder. You can try to restart the encoder or stream at a lower resolution (from 1080p to 720p).


  • Grey image or regular image loss: check your internet connection. If it is low, lower the bitrate.
