HTML to NDI Utility

Turn Most Web Pages in Chromium into an NDI Source

This utility is a simple wrapper around Chromium, the browser engine that powers Google Chrome. It sends HTML pages to NDI, including audio if playback on the page is supported.

Features

• HTTP API that allows changing the web page being rendered to NDI.
• If pages have the background set to transparent, alpha is preserved.
• Audio from the browser instance is sent to NDI.
• Defaults to 1920x1080 @ 60 frames per second.
• Can be set to any resolution.
• Open-source.

Known Limitations

• Frames are sent to NDI in RGBA format. Some machines may experience a slight performance penalty.
• H.264 and any other non-free codecs are not available for video playback since this uses Chromium. Sites like YouTube likely won’t work.
• Audio data received from the browser is passed to NDI directly.
• NDI frame rate is set to 60 frames per second. The internal max render frame rate is set to be capped at 60 frames per second.
