Frequently Asked Questions

Why should I care about multi-bitrate streaming?

  1. Because you can increase viewer’s experience. Each viewer has got limitations on their download speed. Sending multi bitrates ensures less buffering because each viewer connects to the best resolution depending on their current download speed.

What codecs should I use?

You must hold Soho+ or higher service Plan

H264 for video and AAC for audio. If you use any other variations, the live stream most likely won't work on mobile devices.

You have to upgrade your account at least to Soho+. Sign in to your panel and go to Account > Service plans and upgrade your account - Packages & Pricing

How should the resolutions and bitrates be set?

Our recommendations for primary resolution is to set it to 720p @ 1.5 mbits. Next resolution should be 854 x480 @ 800kbps and last one should be 640 x 360 @ 400kbps

Why is there an out of sync message?

Most likely your CPU is overloaded and running over 70%. You may need a more powerful PC such as an Intel Core i7 or you need to reduce the output resolutions so your PC has sufficient power to manage your streams.

I cannot publish my stream. Why?

Most likely your outbound TCP 1935 port is being blocked by your firewall, router or ISP. It could also be that your account is locked or you do not hold active Business or above service plan subscription. Also ensure the stream name ( stream key) is correct without any spaces before or after.
