Eclipse 1.3.4

Eclipse 1.3.4 is the first public release of Eclipse, the screen-side app of the Eclipse + Umbra project: everyday game streaming plus two-PC couch co-op on LG webOS, Windows and Linux. Pair it with Umbra 0.5.0 on the host PCs.

Built from ecb10341. Every package reports version 1.3.4 and that commit.

Downloads

Device	Asset	Notes
LG webOS TV	com.aurora.gamestream_1.3.4_arm.ipk	Install with webOS Dev Manager (Developer Mode). The app id stays com.aurora.gamestream, so an earlier install keeps its settings and pairings.
Windows x64 (installer)	eclipse-windows-x64-setup-unsigned.exe	Per-user install, no administrator rights, no background service. Adds Start menu entries and an Apps & features uninstaller.
Windows x64 (portable)	eclipse-windows-x64-unsigned.zip	Extract everything and run moonlight-tv.exe (inherited executable name).
Linux x86_64	eclipse-linux-x86_64.tar.gz	Extract, then ./install.sh (per-user) or run ./eclipse in place. Needs glibc 2.35+ (Ubuntu 22.04 baseline).

Each asset has a matching .sha256 file, and SHA256SUMS covers everything. Source archives are attached for the exact build (see Source below).

What's in this release

• Two-PC co-op on one screen: two PCs running Umbra each stream half of the picture, joined into one image. Horizontal and vertical splits, with controllers assigned per PC. The co-op pane is built into Umbra 0.5.0 and set up automatically. Mixed NVIDIA + AMD pairs use Umbra's GPU HEVC encoder.
• Co-op sound: both PCs' sound is mixed into one output. Settings → Co-op → "Play shared sounds once" removes the second copy of a sound both PCs play (narration, cutscenes, music), with Accurate (default, look-ahead slider 0–100 ms, default 40), Fast and Off. In this release the filter no longer removes a sound only one PC played: it keeps gunfire and reload sounds it used to cut short (see Tested).
• Disconnect pauses, Quit ends: in co-op, Disconnect pauses both PCs so you can resume, and Quit ends both.
• LG TVs on webOS 26: settings, pairings and co-op keep working after the TV restarts. A restart opens up the Developer Mode app folders; Eclipse locks its own folders again when it starts.
• Installers and clean removal: a Windows per-user installer with a keep-settings option, a Linux per-user installer and uninstaller, and webOS settings in an app-owned, protected folder. Uninstalling removes only what Eclipse owns.
• Support logs: Settings → About → Keep diagnostic logs, then Share logs (on the TV it serves a download page on your network; PINs and passwords are left out).
• No network queries for development hardware: release builds send nothing for the project's own Raspberry Pi controller hub.

Tested

• Co-op sound filter, scored against the game's own sounds: Halo: Combat Evolved's sound files were matched in 76 minutes of recorded two-PC co-op (each PC's own audio, Opus-coded the way it streams). Sounds only one PC played that the filter cut by 6 dB or more went from 7% to 3% (238 to 98 of 3,442); pairs where exactly one copy of a shared sound was removed went from 63% to 68%; pairs where both copies were cut went from 20 to 4.
• The same filter, by ear and live: in side-by-side listening, the maintainer picked this version as the best: the same as the original sound where 1.3.3 cut an assault-rifle burst, gun noises and shotgun-reload shells. A live two-PC co-op session on the LG G5 with the same code (a TV test build) sounded good.
• LG G5, webOS 26 (11.2.0): a long live two-PC co-op Halo session with the 1.3.3 code this release builds on.
• Packages: every package was checked for version 1.3.4 and commit ecb10341, for matching checksums, and for no local paths or user names inside.
• Installing these exact packages:
  • LG G5: the IPK installed over 1.3.3 and kept the existing settings and pairings; Eclipse 1.3.4 launched to the foreground and kept running.
  • Windows 11: the installer upgraded an existing 1.3.2 install silently (/S), left hosts.ini and moonlight.ini byte-identical, and the app started, stayed responsive and closed normally.
  • Linux (WSL): install.sh replaced an existing 1.3.2 install; the app started and ran without errors.

Known issues

• Windows packages are unsigned. Windows SmartScreen may warn. Check the SHA-256 before running. Code signing through SignPath Foundation is being set up.
• Some games pick music or other sound clips at random on each PC. The two PCs then play different clips at the same moment, which the filter cannot merge, so you hear both. Halo: Combat Evolved does this with its music. Turn the game's music off on one PC if it sounds doubled.
• Umbra 0.5.0 does not report its graphics card, so Eclipse asks once for each PC after it is paired, although Settings → Co-op → Graphics cards says Umbra reports it.
• After a TV restart, until Eclipse next starts, other Developer Mode apps could read or change its files. Eclipse locks them again when it starts.
• If the TV restarts before Eclipse is first opened, box art is stored in a temporary folder and downloaded again after each restart.
• The extra audio delay that Accurate adds has not been measured on the TV. Choose Fast or lower the look-ahead if you notice lag.
• Only the LG G5 on webOS 26 has been physically tested. Other LG models and firmware versions need reports. Linux is tested under WSL; native Linux with AMD/Intel VA-API is not yet validated.

Eclipse is a fork of moonlight-tv (GPL-3.0). Upstream names that remain in identifiers and file names (Moonlight, moonlight-tv.exe, com.aurora.gamestream) are kept for compatibility. This project is developed with AI assistance: Claude and Codex write and debug code under the maintainer's direction and hands-on testing. See the Project Hub for details.
