ScreenStream is a user-friendly Android application for streaming your device screen and audio. Use Local mode (MJPEG) or Global mode (WebRTC) to view the stream in a web browser, or use RTSP mode with a compatible RTSP client or player.
The Google Play version supports all modes: Global mode (WebRTC), Local mode (MJPEG), and RTSP mode, with ads included.
F-Droid versions are ad-free and support only Local mode (MJPEG) and RTSP mode.
If ScreenStream is useful to you and you want to support its development, you can use any of the options below.
Preferred (Tether Wallet / Tether.me): dmkr0@tether.me
Tether Wallet supports Tether.me addresses as human-readable identifiers, so this is the simplest option if you already use Tether Wallet.
If you prefer direct on-chain transfers, use one of these addresses:
USD₮ / USA₮ (Ethereum / ERC-20): 0x5bb898c72dd3dD5E7f7A0Ab12854a60374B7c1dA
BTC (on-chain): bc1q8wuv4esej0rdyn2jwkd93v7wvyep7uutzsmlh9
ScreenStream offers three stream modes: Global mode (WebRTC) (available only in the Google Play Store version), Local mode (MJPEG), and RTSP mode. All modes stream the Android device screen, but they function differently. Audio support is available in Global mode (WebRTC) and RTSP mode only. The modes are independent of each other and have different capabilities, restrictions, and customization options.
| Mode | Transport | Audio | Internet required | Server side | Security |
|---|---|---|---|---|---|
| Local mode (MJPEG) | MJPEG over HTTP | ✕ | No | Built-in | Optional 4-6 digit PIN |
| Global mode (WebRTC) | WebRTC | ✓ | Yes | Public signaling service at screenstream.io | End-to-end encryption + password |
| RTSP mode | RTSP H.265/H.264 OPUS/AAC/G.711 |
✓ | No (server) / Depends (client) | Built‑in server (Server mode) / External server (client mode) | Client mode supports RTSP auth + RTSPS (TLS) |
In Global mode (WebRTC) and Local mode (MJPEG), the number of clients is not directly limited, but each client uses CPU resources and separate bandwidth.
ScreenStream uses Android's MediaProjection API and requires Android 6.0 or higher.
Warning
-
High traffic on mobile networks: Streaming over 3G/4G/5G/LTE can consume a large amount of data.
-
Streaming delay: Expect at least 0.5-1 second of delay, and potentially more on slower devices, unstable networks, or under heavy CPU load.
-
Not optimized for video playback: ScreenStream is not designed for streaming video content, especially HD video, so playback quality may not meet your expectations.
Local mode uses MJPEG and a built-in HTTP server. It works on a local network without internet, such as Wi-Fi, a device hotspot, Network-over-USB, or any other network between the Android device and the client's browser.
For optimal performance, a fast and stable network connection is recommended due to high traffic and low network delay requirements.
In Local mode, the app processes each frame independently, one by one, enabling additional image transformations such as cropping, resizing, rotating, and more before sending the image to the client's web browser.
The Local mode offers the following functionality:
- Uses MJPEG.
- PIN protection, no encryption.
- Video only, sent as separate images.
- Works on your local network, no internet required.
- Built-in HTTP server.
- Allows resizing by percentage or exact resolution.
- Supports Wi-Fi, mobile networks, IPv4, and IPv6.
- Clients connect in a browser using the app address.
- Highly customizable.
- Each client uses separate bandwidth.
Note
-
Please be aware that certain cell operators may block incoming connections to your device for security reasons. Consequently, even if your device has an IP address from a cell operator, connecting to the device using this IP address may not be possible.
-
Some Wi-Fi networks, particularly public or guest networks, may block connections between its clients for security reasons. In such cases, connecting to the device via Wi-Fi might not be feasible. For instance, a laptop and a phone within such a Wi-Fi network will not be able to connect to each other.
Screenshots
Global mode in the ScreenStream application is built on WebRTC technology and relies on an external signaling server to facilitate communication between the streaming host (the app) and the streaming client, which is a web browser equipped with the ScreenStream Web Client.
Both the signaling server and the web client for ScreenStream are open-source and available in the ScreenStreamWeb repository. These components are publicly available at screenstream.io. The system is designed to work with modern desktop and mobile browsers that support WebRTC, including Chrome, Safari, Edge, Firefox, and others.
Global mode offers the following functionality:
- Powered by WebRTC technology.
- End-to-end encrypted communication.
- Stream protection with password.
- Supports video and audio streaming.
- Connect using a unique stream ID and password.
- Requires an internet connection for streaming.
- Each client uses separate internet bandwidth.
Note
Global mode (WebRTC) is available only in the Google Play version.

RTSP mode in ScreenStream supports two sub‑modes: server mode (default) hosts this device as an RTSP server, while client mode connects to an external RTSP media server, providing compatibility with a wide range of standard RTSP clients.
For optimal performance, a fast and stable network connection is recommended due to high traffic and low network delay requirements.
- Powered by RTSP protocol.
- Server mode (default) hosts device as an RTSP server.
- Client mode connects to a remote RTSP server (e.g., MediaMTX).
- Supports video and audio with codec configuration.
- Server mode adds protocol, interface/address filters, IPv4/IPv6, and port settings.
- Requires an RTSP client or player for viewing.
- Tested with VLC media player, FFplay, mpv, and gst-play-1.0 (GStreamer) players.
Note
Client mode requires an RTSP‑capable media server (e.g., MediaMTX).
