Hardware Encoders

Hardware encoders provide a compact and portable streaming solution and can be especially useful on film sets. Using a hardware encoder means that you can stream to your room without a computer.


Our hardware encoder step-by-step setup guide can be found here

Hardware encoders have an HDMI and / or SDI port. A source, like an SDI camera feed, is plugged into the encoder and a connection to the internet is established using ethernet, wifi, or mobile data - depending on the encoder's features. The encoder is usually configured using a mobile or web app where the encoder's video and audio settings are adjusted, stream keys are entered, and streaming is started.

General Requirements

Most hardware encoders will work with Louper, provided they support the following:

  • RTMP or SRT streaming protocols
  • H264 / x264 video
  • AAC or Opus audio
  • Ability to set B-frames to 0
  • Ability to set Keyframe Interval of 2 seconds or less
  • Ability to set custom RTMP or SRT urls

To work with Louper, the stream you send must be encoded with zero B-frames and a Keyframe Interval of 2 seconds or less.
