When using SpotMe live streaming services, it is important that you adequately set your source encoder settings, in the case you are using a software audio/video source encoder such as OBS, vMix, Wirecast, XSplit (among others).
Hardware based encoders usually offer the same set of configuration parameters, so this article also applies to these devices.
Browser based solutions such as StreamYard, or online conferencing systems such as Zoom or WebEx, come with pre-configured encoder settings and do not offer any degree of configuration, therefore this article can be bypassed if this is what you are using.
Important: RTMP is not supported. SpotMe streaming supports only RTMPS.
Recommended settings
Protocol
Use RTMP streaming
We only support RTMPS (RTMP over SSL) and do not support unsecured RTMP.

Important notes
- The required internet uplink connection bandwidth for ingesting your live stream in optimal conditions should be at least twice the encoder video output bitrate value.
- It is recommended to use a wired connection for greater bandwidth stability.
- If you are using a shared network (e.g. office), ask your IT to dedicate/reserve bandwidth for your source encoding appliance. If this is not possible, it is recommended you perform a bandwidth measure over a long period of time prior to your live streaming event. Tools such as Networx can be used for this task (https://www.softperfect.com/products/networx/).
- If your are using vMix, make sure that there is no firewall blocking incoming traffic on your system.
- It is not recommended to ingest your live stream at a higher bitrate than 5000 kbps as the highest bitrate available for end user viewing is fixed at 5000 kbps. Going above will result in consuming your uplink bandwidth for nothing.
