This evaluation package contains the current Native sender and its Windows 11 window-capture helper. It has no installer, updater, code signature, or bundled server.

Run

Keep screener-sender.exe and screener-window-capture.exe in the same directory.
Run screener-sender.exe. It opens a loopback-only UI in the default browser; current Chrome or Edge is required.
Enter the Screener server and site access password. Browser VP8 remains the default; browser H.264 and Native window H.264 are explicit opt-ins.
For a browser video source, choose the browser screen/window and optionally select the same window target for process-tree audio. Native window H.264 requires one target and captures its video and process-tree audio together.
Close the console window to stop the sender.

Native capture requires Windows 11 build 22000 or newer. It binds the selected window to its process identity, never falls back to the system mix, and never falls back from the hardware-only Media Foundation H.264 encoder to software. Browser H.264 still requests browser hardware preference without proving which physical encoder Chrome or Edge selected. Viewers use the normal Web client.

Verify the downloaded ZIP against its adjacent .sha256 file, then verify the files inside it with SHA256SUMS.txt. The package is unsigned, so Windows may show an unknown-publisher warning.
