* fix(ffmpeg): bound QSV encoder retries Limit QSV frame submission to 100 retries and synchronization to 10 retries so persistent SDK warnings return an error to the caller. Retain queued buffers when synchronization reaches its retry limit, and allow later calls to retry without latching an error. Wait 1 ms between retryable submission warnings on Windows: the original av_usleep(500) becomes Sleep(0), exhausting the retry budget before even a brief device-busy interval can end. Preserve non-Windows wait behavior and the existing negative SDK result handling. Validated against FFmpeg 7.1.1 on Intel UHD 730 with 42 fault/control cases, synchronization-timeout recovery and close cleanup, real H.264 and HEVC encoding, and separate QSV hardware decoding. Four concurrent 1080p encoders completed 2400 frames without errors. * fix(ffmpeg): handle undersized QSV HEVC buffers Reserve at least three bytes per aligned pixel for HEVC output, following Intel's documented workaround for underestimated bitstream capacity. Check the size before assigning it to AVPacket's integer capacity. Report negative synchronization results before reading output metadata or draining the FIFO, keeping failed tasks owned until encoder close. On Intel UHD 730, the existing code fails at input 242 with real desktop captures; the patched code encodes and decodes all 1,200 inputs. Inputs and PTS match, and the first 241 encoded frames are byte-identical. H.264 also passes 300 frames, and restoring the small buffer verifies error handling. * fix(ffmpeg): refresh QSV HEVC capacity after reset and shorten sync waits * fix(ffmpeg): apply QSV buffer sizing to H.264 * fix: backport FFmpeg hybrid MP4 finalization fix Backport FFmpeg commit 36896af64a9ecf6835758186e7161a2e954c364d so hybrid MP4 finalization writes the final moov before hiding the original fragmented index. Preserve recoverable fragments when the final index cannot be written.

Yet another remote desktop solution, written in Rust. Works out of the box with no configuration required. You have full control of your data, with no concerns about security. You can use our rendezvous/relay server, set up your own, or write your own rendezvous/relay server.
RustDesk welcomes contribution from everyone. See CONTRIBUTING.md for help getting started.
Dependencies
Desktop versions use Flutter or Sciter (deprecated) for GUI. This tutorial is for Sciter only, since it is easier and more friendly to start. Check out our CI for building the Flutter version.
Please download Sciter dynamic library yourself.
Raw Steps to build
-
Prepare your Rust development env and C++ build env
-
Install vcpkg, and set
VCPKG_ROOTenv variable correctly- Windows: vcpkg install libvpx:x64-windows-static libyuv:x64-windows-static opus:x64-windows-static aom:x64-windows-static
- Linux/macOS: vcpkg install libvpx libyuv opus aom
-
run
cargo run

How to build with Docker
Begin by cloning the repository and building the Docker container:
git clone https://github.com/rustdesk/rustdesk
cd rustdesk
git submodule update --init --recursive
docker build -t "rustdesk-builder" .
Then, each time you need to build the application, run the following command:
docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder
Note that the first build may take longer before dependencies are cached, subsequent builds will be faster. Additionally, if you need to specify different arguments to the build command, you may do so at the end of the command in the <OPTIONAL-ARGS> position. For instance, if you wanted to build an optimized release version, you would run the command above followed by --release. The resulting executable will be available in the target folder on your system, and can be run with:
target/debug/rustdesk
Or, if you're running a release executable:
target/release/rustdesk
Please ensure that you run these commands from the root of the RustDesk repository, or the application may not find the required resources. Also note that other cargo subcommands such as install or run are not currently supported via this method as they would install or run the program inside the container instead of the host.
