Apollo

Apollo is a self-hosted desktop stream host for Artemis(Moonlight Noir). Offering low latency, native client resolution, cloud gaming server capabilities with support for AMD, Intel, and Nvidia GPUs for hardware encoding. Software encoding is also available. A web UI is provided to allow configuration and client pairing from your favorite web browser. Pair from the local server or any mobile device.

Major features:

• Built-in Virtual Display with HDR support that matches the resolution/framerate config of your client automatically
• Permission management for clients
• Clipboard sync
• Commands for client connection/disconnection (checkout Auto pause/resume games)
• Input only mode

Usage

Refer to LizardByte's documentation hosted on Read the Docs for now.

Currently Virtual Display support is Windows only, Linux support is planned and will be implemented in the future.

About Permission System

Check out the Wiki

[!NOTE] The FIRST client paired with Apollo will be granted with FULL permissions, then other newly paired clients will only be granted with View Streams and List Apps permission. If you encounter Permission Denied error when trying to launch any app, go check the permission for that device and grant Launch Apps permission. The same applies to the situation when you find that you can't move mouse or type with keyboard on newly paired clients, grant the corresponding client Mouse Input and Keyboard Input permissions.

About Virtual Display

[!WARNING] It is highly recommend to remove any other virtual display solutions from your system and Apollo/Sunshine config, to reduce confusions and compatibility issues.

[!NOTE] TL;DR Just treat your Artemis/Moonlight client like a dedicated PnP monitor with Apollo.

Apollo uses SudoVDA for virtual display. It features auto resolution and framerate matching for your Artemis/Moonlight clients. The virtual display is created upon the stream starts and removed once the app quits. If you do not see a new virtual display added or removed when the stream starts or stops, there may be a driver misconfiguration, or another persistent virtual display might still be active.

The virtual display works just like any physically attached monitors with SudoVDA, there's completely no need for a super complicated solution to "fix" resolution configurations for your devices. Unlike all other solutions that reuses one identity or generate a random one each time for any virtual display sessions, Apollo assigns a fixed identity for each Artemis/Moonlight client, so your display configuration will be automatically remembered and managed by Windows natively.

Configuration for dual GPU laptops

Apollo supports dual GPUs seamlessly.

If you want to use your dGPU, just set the Adapter Name to your dGPU and enable Headless mode in Audio/Video tab, save and restart your computer. No dummy plug is needed any more, the image will be rendered and encoded directly from your dGPU.

About HDR

HDR starts supporting from Windows 11 23H2 and generally supported on 24H2. Some systems might not have HDR toggle on 23H2 and you just need to upgrade to 24H2. Any system lower than 23H2/Windows 10 will not have HDR option available.

[!NOTE] The below section is written for professional media workers. It doesn't stop you from enabling HDR if you know what you're doing and have deep understanding about how HDR works.

Apollo and SudoVDA can handle HDR just fine like any other streaming solutions.

If you have had good experience with HDR previously, you can safely ignore this section.

If you're curious, read on, but don't blame Apollo for poor HDR support.

Whether HDR streaming looks good, it depends completely on your client.

In short, ICC color correction should be totally useless while streaming HDR. It's your client's job to get HDR content displayed right, not the host. But in fact, it does affect the captured video stream and reflect changes on devices that can handle HDR correctly. On other devices that can't, the info is not respected at all.

It's very complicated to explain why HDR is a total mess, and why enabling HDR makes the image appear dark/yellow. If it's your first time got HDR streaming working, and thinks HDR looks awful, you're right, but that's not Apollo's fault, it's your device that tone mapped SDR content to the maximum of the capability of its screen, there's no headroom for anything beyond that actual peak brightness for HDR. For details, please take a look here.

For client devices, usually Apple products that have HDR capability can be trusted to have good results, other than that, your luck depends.

Disclaimer

I got kicked from Moonlight and Sunshine's Discord server and banned from Sunshine's GitHub repo literally for helping people out.

This is what I got for finding a bug, opened an issue, getting no response, troubleshoot myself, fixed the issue myself, shared it by PR to the main repo hoping my efforts can help someone else during the maintenance gap.

Yes, I'm going away. Apollo and Artemis(Moonlight Noir) will no longer be compatible with OG Sunshine and OG Moonlight eventually, but they'll work even better with much more carefully designed features.

The Moonlight repo had stayed silent for 5 months, with nobody actually responding to issues, and people are getting totally no help besides the limited FAQ in their Discord server. I tried to answer issues and questions, solve problems within my ability but I got kicked out just for helping others.

PRs for feature improvements are welcomed here unlike the main repo, your ideas are more likely to be appreciated and your efforts are actually being respected. We welcome people who can and willing to share their efforts, helping yourselves and other people in need.

Update: They have contacted me and apologized for this incident, but the fact it happened still motivated me to start my own fork.
