xCapture

xCapture is a packet capture tool for lighting control protocols. It captures E1.31 (sACN) and ArtNet network traffic and saves it as FSEQ or ESEQ sequence files compatible with xLights and Falcon Player (FPP).

xCapture is part of the xLights family of tools for holiday and entertainment lighting.

Features

• Capture E1.31 (sACN) and Art-Net DMX packets from the network
• Save captured data as FSEQ or ESEQ sequence files
• Configure specific universe ranges to capture
• Automatic frame timing detection
• Trigger-based capture (start/stop on channel value)
• Fill in missing frames for clean playback
