If the recommended parameters do not suit your stream (codecs, custom FPS, ProRes, High 4:4:4, Enhanced RTMP, etc.), write to us in the chat, send an email to support@gcore.com, or contact your manager to find the solution.
For smoother and more reliable streaming, we offer entry servers in key regions including Luxembourg, Ashburn, Miami, and Singapore. By connecting your streaming equipment to the nearest upload server, you can minimize latency and improve performance before the stream is distributed globally through our CDN.
This feature is especially valuable if your streams originate from multiple locations worldwide. You can specify preferred upload servers and the number of streams per region. Our team will then configure your account to match your streaming setup.
Reach out to our support team or your account manager for setup assistance or additional details.
You can use Push or Pull methods where applicable.
Error | Cause | Solution |
SSL issues | You used rtmps://but in the encoder rtmp://is specified |
Check the protocol in your encoder. Follow step 3 of the guide. |
You used a port (80) unsuitable for secure data transfer | Manually add a correct port (443) to the server link, e.g.: rtmp://vp-push-ed1.gvideo.co:443/in/ | |
No transcoding or image degradation when using web cameras with custom video codecs | The video codec H264+ extension has an over-increased keyframe | Check the outgoing live stream parameters of the web camera:
![]() |
“Connection timed out” | The server URL is incorrect | Check the server URL in the encoder settings. Ensure that protocol is rtmps://. |
Your encoder doesn’t support RTMPS | Check if there is RTMPS support, change encoder if required |
