This article describes how to use the AJA Helo Encoder for Livestreaming to the STREAMBOXY video platform.
Requirements
- You have an AJA Helo Encoder and use the latest firmware v4.0
- Your AJA Helo is connected to the internet via ethernet + router and online
- Your internet upstream speed is at least 12 Mbits for a smooth 1080p stream with 25 frames per second
- Your firewall allows outgoing TCP connections via ports 2935 and 2936 (RTMPS) and optionally allows TCP ports 1935 and 1936 as fallback (RTMP)
- You have created a livestream in STREAMBOXY and have the permission to manage the upstream
