# xfirefly Airplay-SDK: a binary receiver package sold as protocol source > The repository ships Android, Windows, hotel and Miracast receiver binaries rather than a buildable project, advertises AirPlay protocol source for sale, and documents its own latency and codec limits candidly. **xfirefly/Airplay-SDK** — The Best Airplay SDK supports Airplay Mirroring and AirPlay Casting to a receiver device. - Repository: https://github.com/xfirefly/Airplay-SDK - Website: http://deeprd.com/ - Stars: 4,007 · Forks: 327 - Language: HTML - License: not declared - Published: 2026-10-07 · Updated: 2026-10-07 · Language: en - Canonical page: https://hysenlabs.com/projects/xfirefly-airplay-sdk ## What is actually committed to the repository This is not a source project. The tree is short and its entries are almost all binaries and images: an Android receiver APK, a separate Android sender APK, a hotel edition receiver APK, a Miracast TV receiver APK, a Windows receiver directory, a macOS and Linux directory, and an `image/` folder for the screenshots. There is no build system, no package manifest, and no compiler source. GitHub classifies the repository as HTML, which is accurate in a literal sense given the README is the only text that matters. So this is a distribution point for prebuilt receiver applications, not a codebase you can read, audit or fork. What is offered beyond the binaries is more interesting, and it is commercial rather than open. The README states plainly that AirPlay protocol source code is sold, runnable on platforms including Linux and Android. That sentence reframes everything else in the repository: the free APKs are demonstrations, and the actual product is the protocol implementation you license. The numbers around that are worth recording. There are 4007 stars, 327 forks and only 2 open issues. Very few forks for a repository with no buildable source is consistent with the tree containing binaries rather than code. The repository was pushed to on 2026-06-29, is not archived, and its single tagged release, 1.5.16, was published on 2022-03-28. ## The feature list, translated and read carefully The README is written in Chinese, with an English version linked at the top, so here is what the claims amount to once translated. The core claim is AirPlay mirroring and casting to a receiver device, with the project description calling it the best AirPlay SDK, which is marketing rather than a measured result and should be read that way. On the video side, the README lists resolution negotiation across 1080p, 2K and 4K, frame rate negotiation at 30 and 60 fps, and support for AirPlay H.265, which the document singles out as important for high-resolution mirroring. It claims AirPlay mirroring at very low latency and gives a figure of 120 milliseconds for the experience of playing racing games without perceptible delay. YouTube casting over AirPlay HLS is supported, as is speed playback and 4K video including content pushed from Chinese streaming apps, though the README notes that 4K depends on the receiver hardware. The wired paths are a genuine differentiator. iPhone and iPad mirroring over a USB cable works by plugging in the data cable, without root, and the README claims the connection survives the screen turning off with frame rate holding at 60 fps. Android USB mirroring is supported with both audio and video over the AOA and ADB protocols. Audio and layout features round it out: ALAC lossless audio transmission, picture-in-picture display mode, portrait display support for phone screens enlarged on vertical advertising displays, up to four simultaneous split screens on one large display, and casting reverse control where the Android receiver controls the sending device. Multiple AirPlay devices can mirror at once, and the Windows section describes one-to-many and many-to-one mirroring for meetings and presentations using a cast code. ## Two receiver editions aimed at different deployments The binaries are not one application with two skins. The home edition is described as full-function wireless and wired phone and computer casting. The hotel edition is a different product with a privacy model: the phone scans a code to bind, and casting is one-to-one, which is a deliberate design for a shared room where you would not want a stranger's device appearing on the network. That distinction is the most useful thing in the README for anyone evaluating the project, because it shows the author thinking about a deployment constraint rather than only about the protocol. A hotel room has a different threat and etiquette model from a living room, and building a scan-to-bind edition is a response to that. The Miracast APK is a separate thing again. It is described as a universal Wi-Fi Display receiver compatible with multiple platforms, which means it speaks the Android Wi-Fi Display protocol rather than AirPlay, and it is included for devices that need that fallback. There is also a download site separate from the repository, plus mirrors of the project on Gitee, and direct contact details including an email address, a WeChat handle and a Telegram channel. A QR code image is committed for the contact section. None of that is a technical signal, but it does tell you the project is run as a commercial operation with support channels rather than a volunteer effort, which is relevant when you are considering the source-code purchase. Screenshots in the tree cover the home edition, the hotel edition, picture-in-picture, music playback, and the four-way split layout, so the visual record of what the receivers look like is committed alongside the binaries. ## The README admits the codec problem directly The most credible section of the document is the one about problems. The README notes that installing the app on some platforms can produce stuttering or delay in mirroring, and attributes this to differences in codec implementations between chip vendors. It says the app is mainly tuned and debugged on Rockchip and Qualcomm phone platforms, that performance is smooth on a Rockchip 3288, and that achieving the best result requires platform-specific debugging and optimization for the chip. That admission is worth more than the feature list. Screen mirroring on an Android box depends on the hardware video decoder behaving the way the author expected, and vendor codec implementations vary in exactly the ways that produce stutter. Naming the affected silicon, claiming one known-good board, and telling integrators to tune per platform is the kind of statement you can act on, and it implicitly concedes that the product is not one-size-fits-all. The same section links to demonstration videos hosted on a Chinese video platform, showing a two-way split and Android casting, which gives you something to watch before committing hardware. The 120 millisecond latency figure should be read in the same light. It appears among the performance claims without a stated measurement method, platform, or resolution, so it is best understood as a target under good conditions rather than a specification you can design against. The README's own admission about codec variance is the more useful input for your own testing plan. ## Licensing is the question to ask before anything else The repository reports no licence at all, and there is no LICENSE file in the tree. For a project whose tree consists entirely of compiled binaries, that is the single most consequential fact, and it is worth stating plainly rather than glossing: without a licence, there is no stated permission to use, modify or redistribute the APKs or the Windows executable, and a commercial engagement would have to be established separately. That is not an accusation, just how open source licensing works. Plenty of vendors ship binaries in public repositories as marketing and negotiate terms privately. But it does mean the stars on this repository, 4007 of them, signal interest rather than adoption, and a developer who wants to depend on this should not read the presence of a public repository as permission to build on it. The same caution applies to the second inconsistency. The single release is 1.5.16 from March 2022, while the repository itself was pushed to in June 2026. Those two facts sit side by side without explanation, so the release tag tells you nothing about the current state of the binaries in the tree. If you need a specific version for a product decision, ask for a version explicitly rather than inferring one from the tag. The commercial path, on the project's own description, is the sale of AirPlay protocol source code for platforms such as Linux and Android. That is a different and more capable proposition than the free APKs, and it is the only part of this repository with a plausible path to integration into a product you own. ## Conclusion Judge this repository as a vendor contact rather than as an open source dependency, because that is what it is: prebuilt receivers, a commercial offer for the protocol source, and a README that reads as a sales document written in Chinese. Two things to settle before you evaluate it seriously. The licence field on the repository is empty, so there is no stated permission for the binaries in the tree, and the only release, 1.5.16, dates from March 2022 even though the repository was pushed to as recently as 2026-06-29. If you need AirPlay on a product, the practical sequence is to install one of the APK receivers on a Rockchip or Qualcomm board, check whether mirroring is smooth for your codec mix, and only then open the licensing conversation, since that conversation determines whether anything here is usable to you. ## FAQ ### What does the xfirefly Airplay-SDK repository actually contain? Committed binaries rather than source: an Android receiver APK, an Android sender APK, a hotel edition receiver APK, a Miracast TV receiver APK, a Windows receiver directory, and screenshots. There is no build system or compiler code in the tree. AirPlay protocol source code is offered for sale separately. ### Does the Airplay-SDK work over a USB cable instead of Wi-Fi? Yes. The README describes wired mirroring for iPhone and iPad by connecting a data cable, with no root required, and claims the connection survives the screen turning off while frame rate holds at 60 fps. Android USB mirroring is also supported with audio and video over the AOA and ADB protocols. ### What are the known limitations of the Airplay-SDK receivers? The README says mirroring can stutter or lag on some platforms because codec implementations differ between chip vendors. It states the app is mainly tuned on Rockchip and Qualcomm hardware, is smooth on a Rockchip 3288, and needs per-chip optimization for best results. Reported latency also depends on the receiver hardware. ## Sources - [Issues](https://github.com/xfirefly/Airplay-SDK/issues) - [Project website](http://deeprd.com/) - [README](https://github.com/xfirefly/Airplay-SDK/blob/master/README.md) - [Releases](https://github.com/xfirefly/Airplay-SDK/releases) - [xfirefly/Airplay-SDK on GitHub](https://github.com/xfirefly/Airplay-SDK) --- Hysen Labs editorial analysis, written from the project's own repository and release notes.
