txproto is a fully scriptable and flexible multimedia streaming/handling program that captures, streams and records from a variety of sources.

• Fully scriptable via Lua
• Fully atomic API
• Every frame is perfect
• Frame-perfect synchronization between video and audio capture
• Custom first-class capture/output code for minimal overhead:
  • Most feature-complete and accurate Pulseaudio implementation, including isolated client capture
  • Zero-copy Wayland capture via the wlr-export-dmabuf-unstable protocol
  • Low-overhead X11 capture via XCB/SHM
  • Wayland capture via the wlr-screencopy-unstable protocol (both software or DMA-BUF frames supported)
• Second-class libavdevice capture/output support
• Headless operation supported
• Optional Vulkan-only GUI via libplacebo, supported window systems:
  • Wayland
• Minimal dependencies (FFmpeg and Lua required, libplacebo and all custom capture code optional)
• Liberally licensed (LGPL v2.1)
